The current Dockerfile is based on a CentOS 7 image, downloads JDK 8, clone the Apache Geode git repository, starts a build and execute the basic tests.
./build-runtime-docker.sh
This may take a while depending on your internet connection, but it's worth since this is a one time step and you endup with a container that is tested and ready to be used for development. It will download Gradle and as part of the build, project dependencies as well.
docker run --rm=true -it -p 10334:10334 -p 7575:7575 -p 1099:1099 geode/runtime:0.1 gfsh
From this point you can pretty much follow Apache Geode in 5 minutes for example:
start server --name=server1
But in order to have real fun with containers you are probably better off using something like docker-compose or kubernetes. Those examples will come next.
Install docker-compose following the instructions on this link and move into the composer directory.
There is a docker-compose.yml example file there with a locator and a server. To start the cluster execute:
docker-compose up
Or in order to start it in background:
docker-compose up -d
Do a docker ps and identify the container ID for the locator. Now you can use gfsh on this container and connect to the distributed system:
docker exec -it <locator_container_id> gfsh
gfsh>connect --locator=locator[10334]
Connecting to Locator at [host=locator, port=10334] ..
Connecting to Manager at [host=192.168.99.100, port=1099] ..
Successfully connected to: [host=192.168.99.100, port=1099]
gfsh>list members
Name | Id
------------ | --------------------------------------
locator | locator(locator:33:locator)<v0>:1351
6e96cc0f6b72 | 172.17.1.92(6e96cc0f6b72:34)<v1>:28140
Type exit and now to scale the cluster you can leverage docker-compose scale command. For example:
docker-compose scale server=3
This will start 2 extra Geode server containers. You can verify this step by repeating the last GFSH step and listing the members.
