This document will take you through deploying ACM Observability on a ROSA cluster. see here for the original documentation.


  • An existing ROSA cluster
  • An Advanced Cluster Management (ACM) deployment

Set up environment

  1. Set environment variables

    export CLUSTER_NAME=my-cluster
    export S3_BUCKET=$CLUSTER_NAME-acm-observability
    export REGION=us-east-2
    export NAMESPACE=open-cluster-management-observability
    export SA=tbd
    export SCRATCH_DIR=/tmp/scratch
    export AWS_ACCOUNT_ID=$(aws sts get-caller-identity --query Account --output text)
    export AWS_PAGER=""
    rm -rf $SCRATCH_DIR
    mkdir -p $SCRATCH_DIR

Prepare AWS Account

  1. Create an S3 bucket

    aws s3 mb s3://$S3_BUCKET
  2. Create a Policy for access to S3

    cat <<EOF > $SCRATCH_DIR/s3-policy.json
        "Version": "2012-10-17",
        "Statement": [
                "Sid": "Statement",
                "Effect": "Allow",
                "Action": [
                "Resource": [
  3. Apply the Policy

    S3_POLICY=$(aws iam create-policy --policy-name $CLUSTER_NAME-acm-obs \
      --policy-document file://$SCRATCH_DIR/s3-policy.json \
      --query 'Policy.Arn' --output text)
    echo $S3_POLICY
  4. Create service account

    aws iam create-user --user-name $CLUSTER_NAME-acm-obs  \
      --query User.Arn --output text
  5. Attach policy to user

    aws iam attach-user-policy --user-name $CLUSTER_NAME-acm-obs \
      --policy-arn ${S3_POLICY}
  6. Create Access Keys

    read -r ACCESS_KEY_ID ACCESS_KEY < <(aws iam create-access-key \
      --user-name $CLUSTER_NAME-acm-obs \
      --query 'AccessKey.[AccessKeyId,SecretAccessKey]' --output text)


Log into the OpenShift cluster that is running your ACM Hub. We’ll set up Observability here

  1. Create a namespace for the observability

    oc new-project $NAMESPACE
  2. Generate a pull secret (this will check if the pull secret exists, if not, it will create it)

    DOCKER_CONFIG_JSON=`oc extract secret/multiclusterhub-operator-pull-secret -n open-cluster-management --to=-` || \
      DOCKER_CONFIG_JSON=`oc extract secret/pull-secret -n openshift-config --to=-` && \
      oc create secret generic multiclusterhub-operator-pull-secret \
      -n open-cluster-management-observability \
      --from-literal=.dockerconfigjson="$DOCKER_CONFIG_JSON" \
  3. Create a Secret containing your S3 details

    cat << EOF | kubectl apply -f -
    apiVersion: v1
    kind: Secret
      name: thanos-object-storage
      namespace: open-cluster-management-observability
    type: Opaque
      thanos.yaml: |
        type: s3
          bucket: $S3_BUCKET
          endpoint: s3.$
          signature_version2: false
          access_key: $ACCESS_KEY_ID
          secret_key: $ACCESS_KEY    
  4. Create a CR for MulticlusterHub

    cat << EOF | kubectl apply -f -
    kind: MultiClusterObservability
      name: observability
      observabilityAddonSpec: {}
          name: thanos-object-storage
          key: thanos.yaml

Access ACM Observability

  1. Log into Advanced Cluster management and access the new Grafana dashboard
