Migrate Installation Images from Ubuntu to UBI

To migrate MongoDB Controllers for Kubernetes Operator from Ubuntu-based images to UBI-based images, edit your Kubernetes Operator configuration file to pull images from the appropriate UBI repositories by suffixing the existing image repository path with -ubi. You don't need to perform this procedure if you are using OpenShift, as you are already using UBI images.

The following example compares a default configuration for the INIT_APPDB_IMAGE_REPOSITORY setting with an updated configuration that pulls a UBI image.

1
spec:
2
  template:
3
    spec:
4
      serviceAccountName: mongodb-kubernetes-operator
5
      containers:
6
        - name: mongodb-kubernetes-operator
7
          image: <operatorVersionUrl>
8
          imagePullPolicy: <policyChoice>
9
          env:
10
            - name: INIT_APPDB_IMAGE_REPOSITORY
11
              value: quay.io/mongodb/mongodb-kubernetes-init-appdb

11
              value: quay.io/mongodb/mongodb-kubernetes-init-appdb

After saving the changes, reapply your configuration file.

For users running vanilla Kubernetes:

kubectl apply -f mongodb-kubernetes.yaml

For users running OpenShift:

oc apply -f mongodb-kubernetes-openshift.yaml

Repeat this procedure for the following repository configurations by applying the same -ubi suffix, saving the changes and reapplying the configuration each time to migrate the images separately:

• AGENT_IMAGE

• INIT_DATABASE_IMAGE_REPOSITORY

• INIT_OPS_MANAGER_IMAGE_REPOSITORY

• MONGODB_ENTERPRISE_DATABASE_IMAGE

• OPS_MANAGER_IMAGE_REPOSITORY
