This chart will deploy Percona XtraDB Cluster in Kubernetes. It will create a Custom Resource, and the Operator will trigger the creation of corresponding Kubernetes primitives: StatefulSets, Pods, Secrets, etc.
To install the chart with the pxc release name using a dedicated namespace (recommended):
helm repo add percona https://percona.github.io/percona-helm-charts/
helm install my-db percona/pxc-db --version 1.15.1 --namespace my-namespaceThe chart can be customized using the following configurable parameters:
| Parameter | Description | Default |
|---|---|---|
crVersion |
Version of the Operator the Custom Resource belongs to | 1.15.1 |

Specify parameters using --set key=value[,key=value] argument to helm install
This is great for a dev cluster as it doesn't require a persistent disk and doesn't bother with a proxy, backups, or TLS.
$ helm install dev --namespace pxc . \
--set proxysql.enabled=false --set tls.enabled=false --set unsafeFlags.tls=true \
--set pxc.persistence.enabled=false --set backup-enabled=falseFirst you need a working cert-manager installed with appropriate Issuers set up. Check out the JetStack Helm Chart to do that.
By setting pxc.certManager=true we're signaling the Helm chart to not create secrets,which will in turn let the operator know to request appropriate certificate resources to be filled by cert-manager.
$ helm install dev --namespace pxc . --set pxc.certManager=trueThe pxc-database chart contains an example production values file that should set you well on your path to running a production database. It is not fully production grade as there are some requirements for you to provide your own secrets for passwords and TLS to be truly production ready, but it does provide comments on how to do those parts.
$ helm install prod --file production-values.yaml --namespace pxc .
