Open source Kubernetes

This is an alternative to deploying YugabyteDB manually using Yugabyte Operator. The Yugabyte operator is available on Red Hat's OperatorHub.io and hence YugabyteDB can be also be deployed using Operator Lifecycle Manager. As the name suggests, OLM is a tool to help deploy and manage Operators on your cluster.

Read on to find out how you can deploy YugabyteDB with OLM.

Prerequisites

A Kubernetes cluster and kubectl configured to talk to the cluster.

Deploy YugabyteDB using Operator Lifecycle Manager

YugabyteDB can be deployed on any Kubernetes cluster using OLM in three easy steps.

Deploy Operator Lifecycle Manager, so that it can manage Operator deployments for you.

$ curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/0.13.0/install.sh | bash -s 0.13.0

Install YugabyteDB operator

$ kubectl create -f https://operatorhub.io/install/yugabyte-operator.yaml

Watch your operator come up until it reaches Succeeded phase.

$ kubectl get csv -n operators

NAME                       DISPLAY             VERSION   REPLACES   PHASE
yugabyte-operator.v0.0.1   Yugabyte Operator   0.0.1                Succeeded

Create YugabyteDB Custom Resource to create YugabyteDB cluster using operator deployed above

$ kubectl create namespace yb-operator && kubectl create -f https://raw.githubusercontent.com/yugabyte/yugabyte-operator/master/deploy/crds/yugabyte.com_v1alpha1_ybcluster_cr.yaml

Watch your YugabyteDB cluster pods come up.

$ kubectl get pods -n yb-operator

NAME           READY   STATUS    RESTARTS   AGE
yb-master-0    1/1     Running   0          3m32s
yb-master-1    1/1     Running   0          3m32s
yb-master-2    1/1     Running   0          3m31s
yb-tserver-0   1/1     Running   0          3m31s
yb-tserver-1   1/1     Running   0          3m31s
yb-tserver-2   1/1     Running   0          3m31s

Configuration flags

For configuration flags, see Configuration flags.

Use YugabyteDB

When all of the pods in YugabyteDB cluster are running, you can use the YSQL shell (ysqlsh) to access the YSQL API, which is PostgreSQL-compliant.

$ kubectl exec -it -n yb-operator yb-tserver-0 -- ysqlsh -h yb-tserver-0  --echo-queries

For details on the YSQL API, see:

Clean up

To remove the YugabyteDB cluster and operator resources, run the following commands.

NOTE: This will destroy your database and delete all of its data.

kubectl delete -f https://raw.githubusercontent.com/yugabyte/yugabyte-operator/master/deploy/crds/yugabyte.com_v1alpha1_ybcluster_cr.yaml
kubectl delete namespace yb-operator
kubectl delete -f https://operatorhub.io/install/yugabyte-operator.yaml
