Two clusters in same namespace

MySQL & MariaDB Percona Operator for MySQL
1

my question is simple

I have one working cluster and I created another one. The only issue is visible that operators are conflicting between each other.

So second operator is:

apiVersion: apps/v1

kind: Deployment

metadata:

 name: percona-xtradb-cluster-operator-2

 namespace: ptest

spec:

 replicas: 1

 selector:

  matchLabels:

   name: percona-xtradb-cluster-operator-2

 template:

  metadata:

   labels:

    name: percona-xtradb-cluster-operator-2

  spec:

   serviceAccountName: percona-xtradb-cluster-operator-2

   containers:

    - name: percona-xtradb-cluster-operator-2

     image: percona/percona-xtradb-cluster-operator:1.4.0

     ports:

     - containerPort: 60000

      name: metrics

     command:

     - percona-xtradb-cluster-operator

     imagePullPolicy: Always

     env:

      - name: WATCH_NAMESPACE

       valueFrom:

        fieldRef:

         fieldPath: metadata.namespace

      - name: OPERATOR_NAME

       value: "percona-xtradb-cluster-operator-2"

Any way to specify that it should use cluster2 instead of cluster1?

$ k get pods -n ptest

percona-xtradb-cluster-operator-7f96c796d7-tpmk8    1/1     Running   0          48m

In operator’s log I can see that these names of “cluster1” and “cluster2” are conflicting. So not right name used in first or second operator.

You only need one operator per namespace.

With one operator you can start multiple cluster instances in that namespace.
