Operator Helm Charts

MinIO publishes Helm Charts for the Helm Operator Charts and Helm Tenant Charts. You can use these charts to deploy the MinIO Operator and managed Tenants through Helm.

The following page documents the values.yaml chart for the MinIO Operator. For documentation on the chart for a MinIO Tenant, see Tenant Helm Charts

MinIO Operator Chart

operator

Root key for Operator Helm Chart

env

An array of environment variables to pass to the Operator deployment. Pass an empty array to start Operator with defaults.

For example:

env:
- name: MINIO_OPERATOR_DEPLOYMENT_NAME
  valueFrom:
    fieldRef:
      fieldPath: metadata.labels['app.kubernetes.io/name']
- name: CLUSTER_DOMAIN
  value: "cluster.domain"
- name: WATCHED_NAMESPACE
  value: ""
- name: MINIO_OPERATOR_RUNTIME
  value: "OpenShift"

See Operator environment variables for a list of all supported values.

image

Specify the Operator container image to use for the deployment. image.tag For example, the following sets the image to the quay.io/minio/operator repo and the v6.0.3 tag. The container pulls the image if not already present:

image:
  repository: quay.io/minio/operator
  tag: v6.0.3
  pullPolicy: IfNotPresent

The chart also supports specifying an image based on digest value:

image:
  repository: quay.io/minio/operator@sha256
  digest: 28c80b379c75242c6fe793dfbf212f43c602140a0de5ebe3d9c2a3a7b9f9f983
  pullPolicy: IfNotPresent
sidecarImage

Specify the sidecar container image to deploy on tenant pods for init container and sidecar. Only need to change this if want to use a different version that the default, or want to set a custom registry. sidecarImage.tag For example, the following sets the image to the quay.io/minio/operator-sidecar repo and the v6.0.3 tag. The container pulls the image if not already present:

sidecarImage:
  repository: quay.io/minio/operator-sidecar
  tag: v6.0.3
  pullPolicy: IfNotPresent

The chart also supports specifying an image based on digest value:

sidecarImage:
  repository: quay.io/minio/operator-sidecar@sha256
  digest: a11947a230b80fb1b0bffa97173147a505d4f1207958f722e348d11ab9e972c1
  pullPolicy: IfNotPresent
imagePullSecrets

An array of Kubernetes secrets to use for pulling images from a private image.repository. Only one array element is supported at this time.

runtimeClassName

The name of a custom Container Runtime to use for the Operator pods.

initContainers

An array of initContainers to start up before the Operator pods. Exercise care as initContainer failures prevent Operator pods from starting. Pass an empty array to start the Operator normally.

replicaCount

The number of Operator pods to deploy. Higher values increase availability in the event of worker node failures.

The cluster must have sufficient number of available worker nodes to fulfill the request. Operator pods deploy with pod anti-affinity by default, preventing Kubernetes from scheduling multiple pods onto a single Worker node.

securityContext

The Kubernetes SecurityContext to use for deploying Operator resources.

You may need to modify these values to meet your cluster’s security and access settings.

containerSecurityContext

The Kubernetes SecurityContext to use for deploying Operator containers. You may need to modify these values to meet your cluster’s security and access settings.

volumes

An array of Volumes which the Operator can mount to pods.

The volumes must exist and be accessible to the Operator pods.

volumeMounts

An array of volume mount points associated to each Operator container.

Specify each item in the array as follows:

volumeMounts:
- name: volumename
  mountPath: /path/to/mount

The name field must correspond to an entry in the volumes array.

nodeSelector

Any Node Selectors to apply to Operator pods.

The Kubernetes scheduler uses these selectors to determine which worker nodes onto which it can deploy Operator pods.

If no worker nodes match the specified selectors, the Operator deployment will fail.

priorityClassName

The Pod Priority to assign to Operator pods.

affinity

The affinity or anti-affinity settings to apply to Operator pods.

These settings determine the distribution of pods across worker nodes and can help prevent or allow colocating pods onto the same worker nodes.

tolerations

An array of Toleration labels to associate to Operator pods.

These settings determine the distribution of pods across worker nodes.

topologySpreadConstraints

An array of Topology Spread Constraints to associate to Operator pods.

These settings determine the distribution of pods across worker nodes.

resources

The Requests or Limits for resources to associate to Operator pods.

These settings can control the minimum and maximum resources requested for each pod. If no worker nodes can meet the specified requests, the Operator may fail to deploy.
