How to upgrade the cluster version

example for upgrading v2.1.0 to the latest version.

step1 update operator

helm repo update
helm upgrade demo radondb/mysql-operator --version 0.1.1

step2 apply new crd

Use the latest version.

kubectl apply -f https://raw.githubusercontent.com/radondb/radondb-mysql-kubernetes/main/charts/mysql-operator/crds/mysql.radondb.com_mysqlclusters.yaml

If the CRD between the two versions does not change, this step is not required.
Backup and User's CRD also need to be updated in the same way. The difference is that you need to get the latest version in the charts/mysql-operator/crds folder in the source code.

step3 apply new cr

kubectl apply -f https://raw.githubusercontent.com/radondb/radondb-mysql-kubernetes/main/config/samples/mysql_v1alpha1_mysqlcluster.yaml
