GreptimeTeam/greptimedb-operator: Run GreptimeDB on Kubernetes.

The GreptimeDB Operator manages the GreptimeDB resources on Kubernetes using the Operator pattern. It is like an autopilot that automates the deployment, provisioning, and orchestration of the GreptimeDB cluster and standalone.

The GreptimeDB Operator includes, but is not limited to, the following features:

• Automated Provisioning

  Automates the deployment of the GreptimeDB cluster and standalone on Kubernetes by providing CRD GreptimeDBCluster and GreptimeDBStandalone.

• Multi-Cloud Support

  Users can deploy the GreptimeDB on any Kubernetes cluster, including on-premises and cloud environments(like AWS, GCP, Aliyun etc.).

• Scaling

  Scale the GreptimeDB cluster as easily as changing the replicas field in the GreptimeDBCluster CR.

• Monitoring Bootstrap

  Bootstrap the GreptimeDB monitoring stack for the GreptimeDB cluster by providing the monitoring field in the GreptimeDBCluster CR.

The GreptimeDB Operator requires at least Kubernetes 1.18.0.

The fastest way to install the GreptimeDB Operator is to use bundle.yaml:

kubectl apply -f \
  https://github.com/GreptimeTeam/greptimedb-operator/releases/latest/download/bundle.yaml \
  --server-side 

The greptimedb-operator will be installed in the greptimedb-admin namespace. When the greptimedb-operator is running, you can see the following output:

$ kubectl get pods -n greptimedb-admin
NAME                                   READY   STATUS    RESTARTS   AGE
greptimedb-operator-7947d785b5-b668p   1/1     Running   0          2m18s

Once the operator is running, you can experience the GreptimeDB by creating a basic standalone instance:

cat <<EOF | kubectl apply -f -
apiVersion: greptime.io/v1alpha1
kind: GreptimeDBStandalone
metadata:
  name: basic
spec:
  base:
    main:
      image: greptime/greptimedb:latest
EOF

When the standalone is running, you can see the following output:

$ kubectl get greptimedbstandalones basic
NAME    PHASE     VERSION   AGE
basic   Running   latest    75s

You can use kubectl port-forward to access the GreptimeDB:

kubectl port-forward svc/basic-standalone 4001:4001 4002:4002 4003:4003 4000:4000

Please refer to the quick-start to try more examples.

The GreptimeDB Operator provides a set of examples to help you understand how to use the GreptimeDB Operator. You can find the examples in the examples directory.

For production use, we recommend deploying the GreptimeDB Operator with the GreptimeDB official Helm chart.
