Architecture

Percona Operators are based on the Operator SDK and leverage Kubernetes primitives to follow best CNCF practices.

Please read more about architecture and design decisions here.

Quickstart installation

Helm

Install the Operator:

helm install my-op percona/pxc-operator

kubectl

It usually takes two steps to deploy Percona XtraDB Cluster on Kubernetes.

Deploy the Operator from deploy/bundle.yaml:

kubectl apply -f https://raw.githubusercontent.com/percona/percona-xtradb-cluster-operator/main/deploy/bundle.yaml

Deploy the database cluster itself from deploy/cr.yaml:

kubectl apply -f https://raw.githubusercontent.com/percona/percona-xtradb-cluster-operator/main/deploy/cr.yaml
