This chart deploys Percona Server for MongoDB Cluster on Kubernetes controlled by Percona Operator for MongoDB.
Useful links:
- Percona Operator for MongoDB running in your Kubernetes cluster. See installation details here or in the Operator Documentation.
- Kubernetes 1.19+
- Helm v3
This chart will deploy Percona Server for MongoDB 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 psmdb release name using a dedicated namespace (recommended):
helm repo add percona https://percona.github.io/percona-helm-charts/
helm install my-db percona/psmdb-db --version 1.13.0 --namespace my-namespaceThe chart can be customized using the following configurable parameters:

Specify parameters using --set key=value[,key=value] argument to helm install
Notice that you can use multiple replica sets only with sharding enabled.
This is great for a dev PSMDB/MongoDB cluster as it doesn't bother with backups and sharding setup.
$ helm install dev --namespace psmdb . \
--set runUid=1001 --set "replsets[0].volumeSpec.pvc.resources.requests.storage=20Gi" \
--set backup.enabled=false --set sharding.enabled=false
