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¶
-
Create the namespace name you will use, if not exist:
$ kubectl create namespace my-namespace-nameTrying to create an already-existing namespace will show you a self-explanatory error message. Also, you can use the
defalutnamespace.Note
In this document
defaultnamespace is used in all examples. Substitutedefaultwith your namespace name if you use a different one. -
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 )
