Install via Helm
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

Install
To install the chart with release name devlake,follow these steps:
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 1Copy 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_SECRETenvironment 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.
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.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.Install the chart by running the following commands:
helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart
helm repo update
helm install devlake devlake/devlake --version=1.0-beta1 --set lake.encryptionSecret.secret=$ENCRYPTION_SECRET
And visit your devlake from the node port (32001 by default).
http://YOUR-NODE-IP:32001
Tips:
If you are using minikube inside your mac, please use the following command to forward the port:
kubectl port-forward service/devlake-ui 30090:4000
and open another terminal:
kubectl port-forward service/devlake-grafana 30091:3000
Then you can visit:
config-ui by url http://YOUR-NODE-IP:30090
grafana by url http://YOUR-NODE-IP:30091
Upgrade
Back up your Grafana dashboards before upgrading if you have modified/customized any dashboards. You can re-import these dashboards to Grafana after the upgrade.
If you are upgrading from DevLake v0.18.x or later versions:
helm repo update
helm upgrade devlake devlake/devlake --version=1.0-beta1
If you are upgrading from DevLake v0.17.x or earlier versions to v0.18.x or later versions:
Copy the ENCODE_KEY value from /app/config/.env of the lake pod (e.g. devlake-lake-0), and replace the <ENCRYPTION_SECRET> in the upgrade command below.
You may encounter the below error when upgrading because the built-in grafana has been replaced by the official grafana dependency. So you may need to delete the grafana deployment first.
Error: UPGRADE FAILED: cannot patch "devlake-grafana" with kind Deployment: Deployment.apps "devlake-grafana" is invalid: spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app.kubernetes.io/instance":"devlake", "app.kubernetes.io/name":"grafana"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: field is immutable
helm repo update
helm upgrade devlake devlake/devlake --version=1.0-beta1 --set lake.encryptionSecret.secret=<ENCRYPTION_SECRET>
Uninstall
To uninstall/delete the devlake release:
helm uninstall devlake
Some example deployments
Deploy with NodePort
Conditions:
- IP Address of Kubernetes node: 192.168.0.6
- Want to visit devlake with port 30000.
ENCRYPTION_SECRET=$(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=$ENCRYPTION_SECRET
After deployed, visit devlake: http://devlake.example.com, and grafana at http://devlake.example.com/grafana
Deploy with Ingress (Https)
Conditions:
- I have already configured ingress(class: nginx) for the Kubernetes cluster, and the https using 8443 port.
- I want to use https://devlake-0.example.com:8443 for visiting devlake.
- The https certificates are generated by letsencrypt.org, and the certificate and key files:
cert.pemandkey.pem
First, create the secret:
kubectl create secret tls ssl-certificate --cert cert.pem --key secret.pem
Then, deploy the devlake:
ENCRYPTION_SECRET=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1)
helm install devlake devlake/devlake \
--set "ingress.enabled=true,ingress.enableHttps=true,ingress.hostname=devlake-0.example.com" \
--set "ingress.className=nginx,ingress.httpsPort=8443" \
--set "ingress.tlsSecretName=ssl-certificate"
--set lake.encryptionSecret.secret=$ENCRYPTION_SECRET
After deployed, visit devlake: https://devlake-0.example.com:8443, and grafana at https://devlake-0.example.com:8443/grafana

FAQ
- 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, 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
- 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
- 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 befalsegrafana.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
- How to set the timezone? If not explicitly set, the default is UTC
commonEnvs.TZ: your timezonegrafana.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=$(openssl rand -base64 2000 | tr -dc 'A-Z' | fold -w 128 | head -n 1)
helm install devlake devlake/devlake \
--set commonEnvs.TZ=<your timezone> \
--set grafana.env.TZ=<your timezone>
- How to set the Grafana admin password? If not explicitly set, a random password will be generated and saved in a Kubernetes Secret
grafana.adminPassword: your password
Here is the example:
helm repo add devlake https://apache.github.io/incubator-devlake-helm-chart
helm repo update
ENCRYPTION_SECRET=$(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
