Percona Operator for MySQL API Documentation

Percona Operator for MySQL based on Percona XtraDB Cluster provides an aggregation-layer extension for the Kubernetes API . Please refer to the official Kubernetes API documentation on the API access and usage details. The following subsections describe the Percona XtraDB Cluster API provided by the Operator.

Prerequisites

1. Create the namespace name you will use, if not exist:

   $ kubectl create namespace my-namespace-name
   

   Trying to create an already-existing namespace will show you a self-explanatory error message. Also, you can use the defalut namespace.

   Note

   In this document default namespace is used in all examples. Substitute default with your namespace name if you use a different one.

2. Prepare

   # set correct API address
   KUBE_CLUSTER=$(kubectl config view --minify -o jsonpath='{.clusters[0].name}')
   API_SERVER=$(kubectl config view -o jsonpath="{.clusters[?(@.name==\"$KUBE_CLUSTER\")].cluster.server}" | sed -e 's#https://##')
   
   # create service account and get token
   kubectl apply --server-side -f deploy/crd.yaml -f deploy/rbac.yaml -n default
   KUBE_TOKEN=$(kubectl get secret $(kubectl get serviceaccount percona-xtradb-cluster-operator -o jsonpath='{.secrets[0].name}' -n default) -o jsonpath='{.data.token}' -n default | base64 --decode )
