Merge pull request #279 from bsig-gh-bot/0.17.2-snapshot-kn905fvxr5 Update snapshot version to 0.17.2-snapshot
Kogito is the next generation of business automation platform focused on cloud-native development, deployment and execution.
To be able to efficiently execute Kogito services on the Cloud there's a need to have Container Images so it can played smoothly on any Kubernetes cluster. There are a few sets images which are divided in three different groups which are the components, the builder images and the runtime images.
To interact with Kogito images, you would need to install the needed dependencies so that the images can be built and tested.
Mandatory dependencies:
Optional dependencies:
Today, the Kogito images are divided basically in 2 vectors, when we talk about images that would be used to assemble or run Kogito applications: Runtime image and Builder image. Those are described bellow.
The Kogito Builder Images are responsible for building the project with Apache Maven and generate the binary that will be used by the Kogito Runtime images to run the Kogito application.
The current available Kogito Builder images are:
The Kogito Quarkus Builder Image allows you to create native image using GraalVM which allows you to have lightweight and fast applications ready to run in the Cloud.
The Kogito Quarkus Builder Image is equipped with the following components:
For more information about what is installed on this image take a look here in the modules.install section.
This image contains a helper option to better understand how to it:
$ docker run -it quay.io/kiegroup/kogito-quarkus-ubi8-s2i:latest /home/kogito/kogito-app-launch.sh -h
By default, a normal java build will be performed. To perform a native build just set the NATIVE build environment variable to true.
See the next topic for an example.
In this example, let's use a simple application available in the Kogito Examples repository: the rules-quarkus-helloworld example, with native compilation disabled.
$ s2i build https://github.com/kiegroup/kogito-examples.git \ --ref master \ --context-dir rules-quarkus-helloworld \ quay.io/kiegroup/kogito-quarkus-ubi8-s2i:latest \ rules-example:1.0 ... [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 08:37 s [INFO] Finished at: 2020-04-06T19:13:42Z [INFO] ------------------------------------------------------------------------ ---> Build finished, installing application from path /tmp/src ---> Installing jar file 'target/rules-quarkus-helloworld-runner.jar' -> '/home/kogito/bin/rules-quarkus-helloworld-runner.jar' ---> Copying application libraries ---> [s2i-core] Copy image metadata file...

INFO ---> [persistence] Skip copying files, persistence directory does not exist... Build completed successfully
After the image is built, let's test it:
$ docker run -it -p 8080:8080 rules-example:1.0 --/ __ \/ / / / _ | / _ \/ //_/ / / / __/ -/ /_/ / /_/ / __ |/ , _/ ,< / /_/ /\ \ --\___\_\____/_/ |_/_/|_/_/|_|\____/___/ 2020-04-08 18:59:57,753 INFO [io.quarkus] (main) rules-quarkus-helloworld 8.0.0-SNAPSHOT (powered by Quarkus 1.3.0.Final) started in 0.839s.

In a different shell, try the following command:
$ curl -H "Content-Type: application/json" -X POST -d '{"strings":["hello"]}' http://localhost:8080/hello # the service will return `["hello", "world"]`
The Kogito Spring Boot Builder Image is equipped with the following components:
For more information about what is installed on this image take a look here in the modules.install section.
This image contains a helper option to better understand how to it:
$ docker run -it quay.io/kiegroup/kogito-springboot-ubi8-s2i:latest /home/kogito/kogito-app-launch.sh -h
In this example, let's use a simple application available in the Kogito Examples repository: the process-springboot-example.
$ s2i build https://github.com/kiegroup/kogito-examples.git \ --ref master \ --context-dir \ process-springboot-example \ quay.io/kiegroup/kogito-springboot-ubi8-s2i:latest \ springboot-example:1.0
After the image is built, let's test it:
$ docker run -it -p 8080:8080 springboot-example:1.0
In a different shell, try the following commands:
$ curl -d '{"approver" : "john", "order" : {"orderNumber" : "12345", "shipped" : false}}' -H "Content-Type: application/json" \ -X POST http://localhost:8080/orders {"id":"10de03c0-828f-4f2e-bb3f-68c3ddfea7ec","approver":"john","order":{"orderNumber":"12345","shipped":false,"total":0.4231905542160477}}✔ $ curl -X GET http://localhost:8080/orders $ curl -X DELETE http://localhost:8080/orders/10de03c0-828f-4f2e-bb3f-68c3ddfea7ec
The time needed to build the application is rather long. This is mainly due to maven downloading all dependencies, which takes several minutes.
If you are planning to build many times the same application, you can use the incremental builds which will improve drastically the build time. Let's start 2 builds with the incremental option enabled and compare the time spent to build each one:
# First incremental build $ time s2i build https://github.com/kiegroup/kogito-examples.git \ --ref master \ --context-dir rules-quarkus-helloworld \ quay.io/kiegroup/kogito-quarkus-ubi8-s2i:latest \ rules-example-incremental:1.0 \ --incremental \ --env NATIVE=false ... real 13m49.819s user 0m1.768s sys 0m1.429s
And now, let's run it again.
# Second incremental build $ time s2i build https://github.com/kiegroup/kogito-examples.git \ --ref master \ --context-dir rules-quarkus-helloworld \ quay.io/kiegroup/kogito-quarkus-ubi8-s2i:latest \ rules-example-incremental:1.0 \ --incremental \ --env NATIVE=false ... real 0m57.582s user 0m1.628s sys 0m1.123s
In the second try, you can see the artifacts getting unpacked and reused from the previous build. Now, pay also attention to the time spent to build it. There is a big difference. In fact, an incremental build reuses the previously built image and it takes advantage of already downloaded artifacts. This can significantly improve the build time.
Another option is to use a Maven Mirror.
This can be used together with incremental builds to speed up the build even more.
To turn it possible we just need to set the MAVEN_MIRROR_URL environment variable when starting a new build, see the example below:
# Third incremental build, with Maven mirror option $ time s2i build https://github.com/kiegroup/kogito-examples.git \ --ref master \ --context-dir rules-quarkus-helloworld \ quay.io/kiegroup/kogito-quarkus-ubi8-s2i:latest \ rules-example-incremental-1 \ --incremental \ --env NATIVE=false \ --env MAVEN_MIRROR_URL=http://nexus.apps.local.cloud/nexus/content/groups/public ... real 0m49.658s user 0m0.968s sys 0m0.539s
Here you can see that the build time has again been reduced. If the maven mirror already have all the dependencies there, the build time can be even faster.
Also, Maven generates lots of transfer logs for downloading/uploading of maven dependencies. By default, these logs are disabled. To view these logs we need to set env variable MAVEN_DOWNLOAD_OUTPUT to true.
If a custom Maven Repository is required, the S2i images also supports it.
In case the MAVEN_REPO_URL environment variable is provided a new Repository and Plugin Repository will be added to the internal settings.xml file.
If no repo-id is provided using the MAVEN_REPO_ID environment variable, a generated one will be used.
There is also the possibility to provide more than one custom Repository. In this case, we need to provide the repo prefix using the MAVEN_REPOS environment variable.
Example, if we want to add two new repositories, the following environment variables is needed:
MAVEN_REPOS="CENTRAL,COMPANY" CENTRAL_MAVEN_REPO_URL="http://central.severinolabs.com/group/public" CENTRAL_MAVEN_REPO_ID="my_cool_id_central" COMPANY_MAVEN_REPO_URL="http://company.severinolabs.com/group/public" COMPANY_MAVEN_REPO_ID="my_cool_id_company"
The Kogito Runtime Images have 2 behaviors:
With this approach, we can have smaller and more compact images that do not include any of the build tools or artifacts (like the local maven repository for example).
Today we have the following Kogito Runtime Images:
A Binary Build allows you to quickly copy the built locally artifacts into the target Kogito Runtime Image, saving the time needed to build the final image using the method with Kogito Builder Images. Below are the supported source structure:
Both methods are described below.
KJAR stands for Knowledge jar which is a custom JAR file that contains Business Process or Rules and all needed dependencies and files to execute it on the target runtime, either Quarkus or Spring Boot.
If you don't have a already existing project, the best way to create a new one is to use Kogito Maven Archetypes to generate project structure. The available archetypes are:
Note that, when building Quarkus based application that is not a UberJAR we also need to copy the lib directory located inside the target directory.
Examples on how to use this feature can be found in the next topics.
This source structure assumes that there is no maven project but only business assets, stored either directly in the top folder or grouped into directories.
Types of Business assets can be:
Upon build, these assets will be copied to a generated maven project and built with Maven to produce a runnable binary. Default value of group id is “com.company”, artifact id is “project” and version is “1.0-SNAPSHOT”. To provide custom value we need to set the PROJECT_GROUP_ID, PROJECT_ARTIFACT_ID and PROJECT_VERSION.
This Kogito Runtime Image contains only the needed files to execute a pre built Kogito application and a JRE.
This image contains a helper option to better understand how to it:
docker run -it quay.io/kiegroup/kogito-quarkus-jvm-ubi8:latest /home/kogito/kogito-app-launch.sh -h
In the next few lines let's take a look on how this image can be used to receive an already built UberJAR. To configure Quarkus to generate a UberJAR please follow the instructions described here
For this example let's use the process-quarkus-example. Once you have checked out the example on your local machine follow the steps below:
Example with UberJAR
# build the example using uberjar reference $ mvn clean package -Dquarkus.package.uber-jar # inspect and run the generated uberjar, for instructions on how to use this example see its README file. $ java -jar target/jbpm-quarkus-example-runner.jar # performing a source to image build to copy the artifacts to the runtime image $ s2i build target/ quay.io/kiegroup/kogito-quarkus-jvm-ubi8:latest process-quarkus-example # run the generated image $ docker run -p 8080:8080 -it process-quarkus-example # On another shell do a simple post request curl -d '{"approver" : "john", "order" : {"orderNumber" : "12345", "shipped" : false}}' -H "Content-Type: application/json" -X POST http://localhost:8080/orders #repare the container logs the following message: Order has been created Order[12345] with assigned approver JOHN
Example with non UberJAR For non uberjar the process is the same, but you only need to remove the property from Quarkus configuration to not generate uberjar.
$ mvn clean package
Note that this time there is a lib folder into the target directory. The s2i build will take care of copying it to the correct place. Just perform a build:
$ s2i build target/ quay.io/kiegroup/kogito-quarkus-jvm-ubi8:latest process-quarkus-example-non-uberjar $ docker run -p 8080:8080 -it process-quarkus-example-non-uberjar # On another shell do a simple post request $ curl -d '{"approver" : "john", "order" : {"orderNumber" : "12345", "shipped" : false}}' -H "Content-Type: application/json" -X POST http://localhost:8080/orders #repare the container logs the following message: Order has been created Order[12345] with assigned approver JOHN
This Kogito Runtime Image contains only the needed files to execute a pre built Kogito application.
This image contains a helper option to better understand how to it:
docker run -it quay.io/kiegroup/kogito-quarkus-ubi8:latest /home/kogito/kogito-app-launch.sh -h
For this example let‘s use the same than the previous one (process-quarkus-example). But this time, let’s perform a native build:
$ mvn clean package -Pnative
A binary has been generated into the target directory. Let's use this binary to perform the source-to-image build:
s2i build target/ quay.io/kiegroup/kogito-quarkus-ubi8:latest binary-test-example -----> [s2i-core] Running runtime assemble script -----> Binary build enabled, artifacts were uploaded directly to the image build -----> Found binary file, native build. -----> Cleaning up unneeded jar files ... ---> Installing application binaries './process-quarkus-example-runner' -> '/home/kogito/bin/process-quarkus-example-runner' ... # run the output image $ docker run -it -p 8080:8080 binary-test-example # on another terminal, interact with the kogito service $ curl -d '{"approver" : "john", "order" : {"orderNumber" : "12345", "shipped" : false}}' -H "Content-Type: application/json" -X POST http://localhost:8080/orders #repare the container logs the following message: Order has been created Order[12345] with assigned approver JOHN
This Kogito Runtime Image contains only the needed files to execute a pre built Kogito application and a JRE.
This image contains a helper option to better understand how to it:
docker run -it quay.io/kiegroup/kogito-springboot-ubi8:latest /home/kogito/kogito-app-launch.sh -h
Let's try, here, the process-springboot-example:
$ mvn clean package
A uberjar file has been generated into the target directory. Let's use this uberjar to perform the build:
$ s2i build target/ quay.io/kiegroup/kogito-springboot-ubi8:latest spring-binary-example -----> [s2i-core] Running runtime assemble script -----> Binary build enabled, artifacts were uploaded directly to the image build -----> Cleaning up unneeded jar files removed 'process-springboot-example-tests.jar' removed 'process-springboot-example-sources.jar' removed 'process-springboot-example-test-sources.jar' -----> Copying uploaded files to /home/kogito ---> [s2i-core] Copy image metadata file...

The Kogito Component Images can be considered as lightweight images that will complement the Kogito core engine by providing extra capabilities, like managing the processes on a web UI or providing persistence layer to the Kogito applications. Today we have 3 Kogito Component Images:
The Data Index Service aims at capturing and indexing data produced by one more Kogito runtime services. For more information please visit this (link)(https://docs.jboss.org/kogito/release/latest/html_single/#proc-kogito-travel-agency-enable-data-index_kogito-deploying-on-openshift). The Data Index Service depends on a running Infinispan or MongoDB Server. The Persistence service can be switched by using its corresponding image
Basic usage with Infinispan:
$ docker run -it --env QUARKUS_INFINISPAN_CLIENT_SERVER_LIST=my-infinispan-server:11222 quay.io/kiegroup/kogito-data-index-infinispan:latest
Basic usage with Mongodb:
$ docker run -it --env QUARKUS_MONGODB_CONNECTION_STRING=mongodb://localhost:27017 quay.io/kiegroup/kogito-data-index-mongodb:latest
To enable debug just use this env while running this image:
docker run -it --env SCRIPT_DEBUG=true --env QUARKUS_INFINISPAN_CLIENT_SERVER_LIST=my-infinispan-server:11222 quay.io/kiegroup/kogito-data-index-infinispan:latest
You should notice a few debug messages present in the system output.
The Kogito Operator can be used to deploy the Kogito Data Index Service to your Kogito infrastructure on a Kubernetes cluster and provide its capabilities to your Kogito applications.
The Explainability Service aims to provide explainability on the decisions that have been taken by kogito runtime applications.
Basic usage
$ docker run -it quay.io/kiegroup/kogito-explainability:latest
To enable debug just use this env while running this image:
docker run -it --env SCRIPT_DEBUG=true quay.io/kiegroup/kogito-explainability:latest

The Kogito Operator can be used to deploy the Kogito Trusty Service to your Kogito infrastructure on a Kubernetes cluster and provide its capabilities to your Kogito applications.
The Kogito Jobs Service is a dedicated lightweight service responsible for scheduling jobs that aim at firing at a given time. It does not execute the job itself but it triggers a callback that could be an HTTP request on a given endpoint specified on the job request, or any other callback that could be supported by the service. For more information please visit this (link)[https://github.com/kiegroup/kogito-runtimes/wiki/Job-Service]
Basic usage:
$ docker run -it quay.io/kiegroup/kogito-jobs-service:latest
To enable debug just use this env while running this image:
docker run -it --env SCRIPT_DEBUG=true quay.io/kiegroup/kogito-jobs-service:latest
You should notice a few debug messages being printed in the system output.
To know what configurations this image accepts please take a look here on the envs section.
The Kogito Operator can be used to deploy the Kogito Jobs Service to your Kogito infrastructure on a Kubernetes cluster and provide its capabilities to your Kogito applications
The Kogito Management Console allows you to have a intuitive way to manage your Kogito processes in execution. It depends on the Kogito Data Index Service on which the Console will connect to so it can be able to manage it. Keep in mind that when using the Process Instance Management Add-on it will enable your Kogito service be manageable through REST API.
To work correctly, the Kogito Management Console needs the Kogito Data Index Service url. If not provided, it will try to connect to the default one (http://localhost:8180).
Basic usage:
$ docker run -it --env KOGITO_DATAINDEX_HTTP_URL=data-index-service-url:9090 quay.io/kiegroup/kogito-management-console:latest
To enable debug just use this env while running this image:
docker run -it --env SCRIPT_DEBUG=true --env KOGITO_DATAINDEX_HTTP_URL=data-index-service-url:9090 quay.io/kiegroup/kogito-management-console:latest
You should notice a few debug messages being printed in the system output.
To know what configurations this image accepts please take a look here on the envs section.
The Kogito Operator can be used to deploy the Kogito Management Console to your Kogito infrastructure on a Kubernetes cluster and provide its capabilities to your Kogito applications.
The Kogito Trusty UI provides an audit tool that allows you to retrieve and inspect the decisions that have been taken by Kogito Runtime Services. It depends on the Kogito Trusty Service on which the Trusty UI will connect to so it can be able to retrieve the information to display.
To work correctly, the Kogito Trusty UI needs the Kogito Trusty Service url. If not provided, it will try to connect to the default one (http://localhost:8180).
Basic usage:
$ docker run -it --env KOGITO_TRUSTY_ENDPOINT=trusty-service-url:9090 quay.io/kiegroup/kogito-trusty-ui:latest

You should notice a few debug messages being printed in the system output.
To know what configurations this image accepts please take a look here on the envs section.
The Kogito Operator can be used to deploy the Kogito Trusty UI to your Kogito infrastructure on a Kubernetes cluster and provide its capabilities to your Kogito applications.
Once the images are built and imported into a registry (quay.io or any other registry), new applications can be built and deployed within a few steps.
As a first step, we need to make the Kogito Images available as Image Streams in OpenShift. If you have cluster-admin rights you can deploy it into the openshift namespace, otherwise, deploy it into the namespace where you have permissions. To install the image stream use this imagestream file: kogito-imagestream.yaml. It points to the latest released version.
Let's use the rules-quarkus-helloworld from Kogito Examples.
# creating a new namespace $ oc new-project rules-quarkus-helloworld Now using project "rules-quarkus-helloworld" on server "https://ocp.lab.cloud:8443". You can add applications to this project with the 'new-app' command. For example, try: oc new-app centos/ruby-25-centos7~https://github.com/sclorg/ruby-ex.git to build a new example application in Ruby. # installing the imagestream on the current namespace $ oc create -f https://raw.githubusercontent.com/kiegroup/kogito-images/0.16.0/kogito-imagestream.yaml imagestream.image.openshift.io/kogito-quarkus-ubi8 created imagestream.image.openshift.io/kogito-quarkus-jvm-ubi8 created imagestream.image.openshift.io/kogito-quarkus-ubi8-s2i created imagestream.image.openshift.io/kogito-springboot-ubi8 created imagestream.image.openshift.io/kogito-springboot-ubi8-s2i created imagestream.image.openshift.io/kogito-data-index-infinispan created imagestream.image.openshift.io/kogito-data-index-mongodb created imagestream.image.openshift.io/kogito-trusty created imagestream.image.openshift.io/kogito-jobs-service created imagestream.image.openshift.io/kogito-management-console created # performing a new build $ oc new-build --name=rules-quarkus-helloworld-builder --image-stream=kogito-quarkus-ubi8-s2i:0.9.0 \ https://github.com/kiegroup/kogito-examples.git#master --context-dir=rules-quarkus-helloworld \ --strategy=source --env NATIVE=false --> Found image 8c9d756 (5 days old) in image stream "rules-quarkus-helloworld/kogito-quarkus-ubi8-s2i" under tag "0.9.0" for "kogito-quarkus-ubi8-s2i:0.9.0" Kogito based on Quarkus ----------------------- Platform for building Kogito based on Quarkus Tags: builder, kogito, quarkus * The source repository appears to match: jee * A source build using source code from https://github.com/kiegroup/kogito-examples.git#master will be created * The resulting image will be pushed to image stream tag "rules-quarkus-helloworld-builder:latest" * Use 'start-build' to trigger a new build --> Creating resources with label build=drools-helloworld-builder ... imagestreamtag.image.openshift.io "rules-quarkus-helloworld-builder:latest" created buildconfig.build.openshift.io "rules-quarkus-helloworld-builder" created --> Success
The build has started, you can check the logs with the following command:
$ oc logs -f bc/rules-quarkus-helloworld-builder
Once the build is finished, you can now create a new build to copy the generated artifact from the source to image build to the Kogito Runtime Image. To do this, execute the following command:
$ oc new-build --name=rules-quarkus-helloworld-service --source-image=rules-quarkus-helloworld-builder \ --source-image-path=/home/kogito/bin:. --image-stream=kogito-quarkus-jvm-ubi8:0.9.0 --> Found image 1608e71 (6 days old) in image stream "rules-quarkus-helloworld/kogito-quarkus-jvm-ubi8" under tag "0.9.0" for "kogito-quarkus-jvm-ubi8:0.9.0" Kogito based on Quarkus JVM image --------------------------------- Runtime image for Kogito based on Quarkus JVM image Tags: builder, runtime, kogito, quarkus, jvm * A source build using <unknown> will be created * The resulting image will be pushed to image stream tag "rules-quarkus-helloworld-service:latest" * Use 'start-build' to trigger a new build --> Creating resources with label build=drools-helloworld-service ... imagestream.image.openshift.io "rules-quarkus-helloworld-service" created buildconfig.build.openshift.io "rules-quarkus-helloworld-service" created --> Success
Follow the logs with the following command:
$ oc logs -f bc/rules-quarkus-helloworld-service
Once the build gets finished, you need to create an application and use the service image created with the latest command.
$ oc new-app rules-quarkus-helloworld-service:latest --> Found image 664b295 (3 minutes old) in image stream "rules-quarkus-helloworld/rules-quarkus-helloworld-service" under tag "latest" for "rules-quarkus-helloworld-service:latest" temp.builder.openshift.io/rules-quarkus-helloworld/rules-quarkus-helloworld-service-1:e8062a99 --------------------------------------------------------------------------------------- Runtime image for Kogito based on Quarkus JVM image Tags: builder, runtime, kogito, quarkus, jvm * This image will be deployed in deployment config "rules-quarkus-helloworld-service" * Port 8080/tcp will be load balanced by service "rules-quarkus-helloworld-service" * Other containers can access this service through the hostname "rules-quarkus-helloworld-service" --> Creating resources ... deploymentconfig.apps.openshift.io "rules-quarkus-helloworld-service" created service "rules-quarkus-helloworld-service" created --> Success Application is not exposed. You can expose services to the outside world by executing one or more of the commands below: 'oc expose svc/rules-quarkus-helloworld-service' Run 'oc status' to view your app.
As described in the command output, to be able to access the application, we need to expose it to the external world. For that, just execute the command listed in the output above, e.g.:
$ oc expose svc/rules-quarkus-helloworld-service
To see the route name, just execute the following command:
$ oc get routes NAME HOST/PORT PATH SERVICES PORT TERMINATION WILDCARD rules-quarkus-helloworld-service rules-quarkus-helloworld-service-rules-quarkus-helloworld.apps.lab.cloud rules-quarkus-helloworld-service 8080-tcp None
Now, with the service address in hand we can test our service:
$ curl -H "Content-Type: application/json" -X POST -d '{"strings":["hello"]}' \ http://rules-quarkus-helloworld-service-rules-quarkus-helloworld.apps.lab.cloud/hello
As output you should see the following response:
["hello","world"]
For more complex deployment, please use the Kogito Cloud Operator
To be able to build the image it should be installed and available on OpenShift before it can be used.
Suppose we have built the Quarkus s2i Image with the following command:
$ make kogito-quarkus-ubi8-s2i
We'll have as output the following image:
quay.io/kiegroup/kogito-quarkus-ubi8-s2i:X.X.X
Then we need to tag the image properly. Suppose your local registry is openshift.local.registry:8443, you should do:
$ docker tag quay.io/kiegroup/kogito-quarkus-ubi8-s2i:X.X.X \ openshift.local.registry:8443/{NAMESPACE}/kogito-quarkus-ubi8-s2i:X.X.X
Where the namespace is the place where you want the image to be available for usage. Once the image is properly tagged, log in to the registry and push the new image:
$ docker login -u <USERNAME> -p <PASSWORD> openshift.local.registry:8443 $ docker push openshift.local.registry:8443/{NAMESPACE}/kogito-quarkus-ubi8-s2i:X.X.X
To deploy and test the new image, follow the same steps as described here
Before proceed please make sure you have checked the requirements.
To build the images for local testing there is a Makefile which will do all the hard work for you. With this Makefile you can:
Build and test all images with only one command:
$ make
If there's no need to run the tests just set the ignore_test env to true, e.g.:
$ make ignore_test=true
Test all images with only one command, no build triggered, set the ignore_build env to true, e.g.:
$ make ignore_build=true
Build images individually, by default it will build and test each image
$ make build-image image_name=kogito-quarkus-ubi8 $ make build-image image_name=kogito-quarkus-jvm-ubi8 $ make build-image image_name=kogito-quarkus-ubi8-s2i $ make build-image image_name=kogito-springboot-ubi8 $ make build-image image_name=kogito-springboot-ubi8-s2i $ make build-image image_name=kogito-data-index-infinispan $ make build-image image_name=kogito-data-index-mongodb $ make build-image image_name=kogito-trusty $ make build-image image_name=kogito-explainability $ make build-image image_name=kogito-jobs-service $ make build-image image_name=kogito-management-console $ make build-image image_name=kogito-trusty-ui
We can ignore the build or the tests while interacting with a specific image as well, to build only:
$ make ignore_test=true image_name={image_name}
Or to test only:
$ make ignore_build=true image_name={image_name}
Build and Push the Images to quay or a repo for you preference, for this you need to edit the Makefile accordingly: bash $ make push It will create 3 tags: - X.Y - X.Y.z - latest
to push a single image:
```bash
$ make push-image image_name={image_name}
```
Push staging images (release candidates, a.k.a rcX tags), the following command will build and push RC images to quay. bash $ make push-staging To override an existing tag use: bash $ make push-staging override=-o It uses the push-staging.py script to handle the images.
Push images to a local registry for testing bash $ make push-local-registry REGISTRY=docker-registry-default.apps.spolti.cloud NS=spolti-1 It uses the push-local-registry.sh script properly tag the images and push to the desired registry.
You can also add cekit_option to the make command, which will be appended to the Cekit command. Default is cekit -v.
CeKit can use modules to better separate concerns and reuse these modules on different images. On the Kogito Images we have several CeKit modules that are used during builds. To better understand the CeKit Modules, please visit this link.
Below you can find all modules used to build the Kogito Images
For each image, we use a specific *-overrides.yaml file which will specific the modules needed. Please inspect the images overrides files to learn which modules are installed on each image:
There is two kind of tests, behave and bats tests.
For more information about behave tests please refer this link
To run all behave tests:
make test
CeKit also allows you to run a specific test. See Writing Behave Tests.
You can also add cekit_option to the make command, which will be appended to the Cekit command. Default is cekit -v.
With the Cekit extension of behave we can run, practically, any kind of test on the containers, even source to image tests. There are a few options that you can use to define what action and what kind of validations/verifications your test must do. The behave test structure looks like:
Feature my cool feature Scenario test my cool feature - it should print Hello and World on logs Given/when image is built/container is ready Then container log should contain Hello And container log should contain World
One feature can have as many scenarios as you want. But one Scenario can have one action defined by the keywords given or when, the most common options for this are:
The Then clause is used to do your validations, test something, looking for a keyword in the logs, etc. If you need to validate more than one thing you can add a new line with the And keyword, like this example:
Scenario test my cool feature - it should print Hello and World on logs Given/when image is built/container is ready Then container log should contain Hello And container log should contain World And container log should not contain World!! And file /opt/eap/standalone/deployments/bar.jar should not exist
The most common sentences are:
CeKit allow us to use tags, it is very useful to segregate tests, if we want to run only the tests for the given image, we need to annotate the test specific or the entire feature with the image name, for example, we have the common tests that needs to run against almost all images, instead to add the same tests for every image feature, we create a common feature and annotate it with the images we want that specific test or feature to run, a example can be found on this common test For example, suppose you are working on a new feature and add tests to cover your changes. You don't want to run all existing tests, this can be easily done by adding the @wip tag on the behave test that you are creating.
All images have already test feature files. If a new image is being created, a new feature file will need to be created and the very first line of this file would need to contain a tag with the image name.
For example, if we are creating a new image called quay.io/kiegroup/kogito-moon-service, we would have a feature called kogito-moon-service.feature under the tests/features directory and this file will looks like with the following example:
@quay.io/kiegroup/kogito-data-index-infinispan Feature: Kogito-data-index-infinispan feature. ... Scenarios......
For a complete list of all available sentences, please refer the CeKit source code: https://github.com/cekit/behave-test-steps/tree/v1/steps
What is Bats tests ? From Google: Bats is a TAP-compliant testing framework for Bash. It provides a simple way to verify that the UNIX programs you write behave as expected.
A Bats test file is a Bash script with special syntax for defining test cases.
Under the hood, each test case is just a function with a description.
To run the bats tests, we need to specify which module and test we want to run.
As an example, let's execute the tests from the kogito-s2i-core module:
$ bats modules/kogito-s2i-core/tests/bats/s2i-core.bats ✓ test manage_incremental_builds ✓ test assemble_runtime no binaries ✓ test assemble_runtime with binaries binaries ✓ test assemble_runtime with binaries binaries and metadata ✓ test runtime_assemble ✓ test runtime_assemble with binary builds ✓ test runtime_assemble with binary builds entire target! ✓ test handle_image_metadata_json no metadata ✓ test handle_image_metadata_json with metadata ✓ test copy_kogito_app default java build no jar file present ✓ test copy_kogito_app default java build jar file present ✓ test copy_kogito_app default quarkus java build no jar file present ✓ test copy_kogito_app default quarkus java build uberJar runner file present ✓ test copy_kogito_app default quarkus native builds file present ✓ build_kogito_app only checks if it will generate the project in case there's no pom.xml ✓ build_kogito_app only checks if it will a build will be triggered if a pom is found 16 tests, 0 failures
The best way to start to interact with Bats tests is take a look on its documentation and after use the existing ones as example.
Here you can find a basic example about how our Bats tests are structured.
For the Kogito Images, we use the Jira issue tracker under the KOGITO project. And to specify that the issue is specific to the Kogito images, there is a component called Image that should be added for any issue related to this repository.
When submitting the Pull Request with the fix for the reported issue, and for a better readability, we use the following pattern:
