| The steps to install Apache DevLake via Helm for Kubernetes |
| sidebar_position: 2 |
| --- |
| |
| ## Prerequisites |
| |
| - Helm >= 3.6.0 |
| - Kubernetes >= 1.19.0 |
| |
| ## Quick Start |
| |
| #### You can also check https://github.com/apache/incubator-devlake-helm-chart to make contribution |
| |
| #### To install or upgrade to the latest version, please check [here](https://github.com/apache/incubator-devlake-helm-chart/releases) |
| |
| ### Install |
| |
| To install the chart with release name `devlake`,follow these steps: |
| |
| 1. Generate a secure encryption key using a method such as OpenSSL. For example, run the following command to generate a 128-character string consisting of uppercase letters: |
| |
| ``` |
| openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1 |
| ``` |
| |
| 2. Copy the generated string, set the value of the ENCRYPTION_SECRET environment variable by running the following command: |
| |
| ``` |
| export ENCRYPTION_SECRET="copied string" |
| ``` |
| |
| This command will set the `ENCRYPTION_SECRET` environment variable to the value of the copied string. |
| |
| **Please make sure to keep the ENCRYPTION_SECRET safe as it is used to encrypt sensitive information in the database, such as personal access tokens and passwords. If ENCRYPTION_SECRET is lost, it may not be possible to decrypt this sensitive information.** |
| |
| 3. By default, the timezone is UTC. To customize the timezone settings, apply the `--set commonEnvs.TZ="your timezone",grafana.env.TZ="your timezone"` command. For further guidance, please refer to [FAQ](#faq). |
| |
| 4. By default, a random password is generated and stored in a Kubernetes Secret for the Grafana admin user. Alternatively, you can explicitly set the password via `--set grafana.adminPassword=<your password>`. For further guidance, please refer to [FAQ](#faq). |
| |
| 5. Install the chart by running the following commands: |
| |
| ```shell |
| helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart |
| helm repo update |
| helm install devlake devlake/devlake --version=0.19.0-beta6 --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |
| ``` |
| |
| And visit your devlake from the node port (32001 by default). |
| |
| http://YOUR-NODE-IP:32001 |
| |
| #### Tips: |
| |
| If you are using minikube inside your mac, please use the following command to forward the port: |
| |
| ```shell |
| kubectl port-forward service/devlake-ui 30090:4000 |
| ``` |
| |
| and open another terminal: |
| |
| ```shell |
| kubectl port-forward service/devlake-grafana 30091:3000 |
| ``` |
| |
| Then you can visit: |
| config-ui by url `http://YOUR-NODE-IP:30090` |
| grafana by url `http://YOUR-NODE-IP:30091` |
| |
| ### Upgrade |
| |
| **Note:** |
| |
| **Back up your Grafana dashboards** before upgrading if you have modified/customized any dashboards. You can re-import these dashboards to Grafana after the upgrade. |
| |
| **If you're upgrading from DevLake v0.17.x or earlier versions to v0.18.x or later versions:** |
| |
| 1. Copy the ENCODE_KEY value from /app/config/.env of the lake pod (e.g. devlake-lake-0), and replace the <ENCRYPTION_SECRET> in the upgrade command below. |
| |
| 2. You may encounter the below error when upgrading because the built-in grafana has been replaced by the official grafana dependency. So you may need to delete the grafana deployment first. |
| |
| > Error: UPGRADE FAILED: cannot patch "devlake-grafana" with kind Deployment: Deployment.apps "devlake-grafana" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/instance":"devlake", "app.kubernetes.io/name":"grafana"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable |
| |
| ```shell |
| helm repo update |
| helm upgrade devlake devlake/devlake --version=0.19.0-beta6 --set lake.encryptionSecret.secret=<ENCRYPTION_SECRET> |
| ``` |
| |
| **If you're upgrading from DevLake v0.18.x or later versions:** |
| |
| ```shell |
| helm repo update |
| helm upgrade devlake devlake/devlake --version=0.19.0-beta6 |
| ``` |
| |
| ### Uninstall |
| |
| To uninstall/delete the `devlake` release: |
| |
| ```shell |
| helm uninstall devlake |
| ``` |
| |
| ## Some example deployments |
| |
| ### Deploy with NodePort |
| |
| Conditions: |
| |
| - IP Address of Kubernetes node: 192.168.0.6 |
| - Want to visit devlake with port 30000. |
| |
| ``` |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake --set service.uiPort=30000 --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |
| ``` |
| |
| After deployed, visit devlake: http://192.168.0.6:30000 |
| |
| ### Deploy with Ingress |
| |
| Conditions: |
| |
| - I have already configured default ingress for the Kubernetes cluster |
| - I want to use http://devlake.example.com for visiting devlake |
| |
| ``` |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake --set "ingress.enabled=true,ingress.hostname=devlake.example.com" --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |

| ## FAQ |
| |
| 1. Can I use a managed Cloud database service instead of running database in docker? |
| |
| Yes, it just set useExternal value to true while you deploy devlake with helm chart. Below we'll use MySQL on AWS RDS as an example. |
| |
| a. (Optional) Create a MySQL instance on AWS RDS following this [doc](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_GettingStarted.CreatingConnecting.MySQL.html), skip this step if you'd like to use an existing instance |
| b. Proviede below values while install from helm: |
| |
| - `mysql.useExternal`: this should be `true` |
| - `mysql.externalServer`: use your RDS instance's IP address or domain name. |
| - `mysql.externalPort`: use your RDS instance's database port. |
| - `mysql.username`: use your `username` for access RDS instance's DB |
| - `mysql.password`: use your `password` for access RDS instance's DB |
| - `mysql.database`: use your RDS instance's DB name, you may need to create a database first with `CREATE DATABASE <DB name>;` |
| |
| Here is the example: |
| |
| ``` |
| helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart |
| helm repo update |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake \ |
| --set mysql.useExternal=true \ |
| --set mysql.externalServer=db.example.com \ |
| --set mysql.externalPort=3306 \ |
| --set mysql.username=admin \ |
| --set mysql.password=password_4_admin \ |
| --set mysql.database=devlake |
| --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |
| |
| ``` |
| |
| 2. Can I use a secret to store the database connection details? |
| |
| Yes, to do so, you need to have a secret in your Kubernetes Cluster that contains the following values: |
| |
| - `MYSQL_USER`: The user to connect to your DB. |
| - `MYSQL_PASSWORD`: The password to connect to your DB. |
| - `MYSQL_DATABASE`: The database to connect to your DB. |
| - `MYSQL_ROOT_PASSWORD`: The root password to connect to your DB. |
| - `DB_URL`: mysql://`username`:`password`@`dbserver`:`port`/`database`?charset=utf8mb4&parseTime=True |
| |
| The secret name needs to be the same as the value `option.connectionSecretName` |
| |
| 3. Can I use an external Grafana instead of running built-in Grafana? |
| |
| Yes, the devlake helm chart supports using an external Grafana. You can set the following values while installing from helm: |
| |
| - `grafana.enabled`: this should be `false` |
| - `grafana.external.url`: use your Grafana's URL, e.g. `https://grafana.example.com` |
| |
| Here is the example: |
| |
| ``` |
| helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart |
| helm repo update |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake \ |
| --set grafana.enabled=false \ |
| --set grafana.external.url=https://grafana.example.com |
| --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |
| |
| ``` |
| |
| 4. How to set the timezone? If not explicitly set, the default is UTC |
| |
| - `commonEnvs.TZ`: your timezone |
| - `grafana.env.TZ`: your timezone |
| |
| Here is the example: |
| |
| ``` |
| helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart |
| helm repo update |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake \ |
| --set commonEnvs.TZ=<your timezone> \ |
| --set grafana.env.TZ=<your timezone> |
| |
| ``` |
| |
| 5. How to set the Grafana admin password? If not explicitly set, a random password will be generated and saved in a Kubernetes Secret |
| |
| - `grafana.adminPassword`: your password |
| |
| Here is the example: |
| |
| ``` |
| helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart |
| helm repo update |
| ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1) |
| helm install devlake devlake/devlake \ |
| --set grafana.adminPassword=<your password> \ |
| --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET |
| |
| ``` |
