Install Percona XtraDB Cluster with customized parameters¶

You can customize the configuration of Percona XtraDB Cluster and install it with customized parameters.

To check available configuration options, see deploy/cr.yaml and Custom Resource Options.

kubectlHelm

To customize the configuration, do the following:

Clone the repository with all manifests and source code by executing the following command:
```
$ git clone -b v1.14.1 https://github.com/percona/percona-xtradb-cluster-operator
```
Edit the required options and apply the modified deploy/cr.yaml file as follows:
```
$ kubectl apply -f deploy/cr.yaml
```

To install Percona XtraDB Cluster with custom parameters, use the following command:

$ helm install --set key=value

You can pass any of the Operator’s Custom Resource options as a --set key=value[,key=value] argument.

The following example deploys a Percona XtraDB Cluster in the pxc namespace, with disabled backups and 20 Gi storage:

Command lineYAML file

$ helm install my-db percona/pxc-db --version 1.14.1 --namespace pxc \
  --set pxc.volumeSpec.resources.requests.storage=20Gi \
  --set backup.enabled=false

You can specify customized options in a YAML file instead of using separate command line parameters. The resulting file similar to the following example looks as follows:

values.yaml

allowUnsafeConfigurations: true
sharding:
  enabled: false
pxc:
  size: 3
  volumeSpec:
    pvc:
      resources:
        requests:
          storage: 2Gi
backup:
  enabled: false

Apply the resulting YAML file as follows:

$ helm install my-db percona/pxc-db --namespace pxc -f values.yaml
