Chapter 4. Installing the Red Hat Integration - AMQ Interconnect Operator in a restricted environment

Prerequisites

• Access to registry.redhat.io

  1. Login to registry.redhat.io from the RHEL machine.

     $ podman login -u USERNAME -p PASSWORD registry.redhat.io

  2. Keep only the Interconnect Operator in the list of operators:

     $ opm index prune -f registry.redhat.io/redhat/redhat-operator-index:v<openshift-version> -p amq7-interconnect-operator -t <cluster-domain>:<registry-port>/iib:my-operator-iib

     Copy to Clipboard Toggle word wrap

     where

     • <openshift-version> is the version of OpenShift Container Platform, for example, 4.9.
     • <cluster-domain> is the domain name for the OpenShift Container Platform cluster, for example, mycluster.example.com.
     • <registry-port> is the port number used by the registry in the OpenShift Container Platform cluster, the default being 5000.

     Verify that you have only created a podman image of the Interconnect Operator:

     $ podman images | grep my-operator-iib <cluster-domain>:<registry-port>/iib

Prerequisites

• Access from the RHEL machine to the OpenShift Container Platform cluster.

  1. From the RHEL machine, push the image to the cluster registry :

     $ podman push <cluster-domain>:<registry-port>/iib:my-operator-iib

  2. Create the three files required for the mirroring process :

     $ /usr/local/bin/oc adm catalog mirror  \
       <cluster-domain>:<registry-port>/iib:my-operator-iib \
       <cluster-domain>:<registry-port> \
       -a /home/customer-user/.docker/config.json \
       --insecure=true \
       --registry-config /home/customer-user/.docker/config.json \
       --index-filter-by-os=linux/amd64 \
       --manifests-only

  3. Make sure that the following files exist:

     • catalogSource.yaml - A YAML file describing the catalogSource.
     • imageContentSourcePolicy.yaml - A YAML file that maps the images in the internal registry with the addresses from RedHat registries.
     • mapping.txt- A text file that drives the mirroring process of the images to the internal registry.

  4. Edit mapping.txt to list only the images you want to mirror.

     The file has the following format:

     [ Operator address on RedHat registry : Operator SHA ] = [ Operator address on internal mirror registry : tag ]

     Example of a mapping.txt file :

     registry.redhat.io/amq7/amq-interconnect@sha256:6101cc735e4d19cd67c6d80895c425ecf6f1d2604d88f999fa0cae57a7d6abaf=<cluster-domain>:<registry-port>/amq7-amq-interconnect:f793b0cc
     registry.redhat.io/amq7/amq-interconnect-operator@sha256:8dd53290c909589590b88a1544d854b4ad9f8b4a639189597c0a59579bc60c40=<cluster-domain>:<registry-port>/amq7-amq-interconnect-operator:73c142ff
     registry.redhat.io/amq7/amq-interconnect-operator-metadata@sha256:799ce48905d5d2a91b42e2a7943ce9b756aa9da80f6924be06b2a6275ac90214=<cluster-domain>:<registry-port>/amq7-amq-interconnect-operator-metadata:14cc4a4e

  5. Mirror the required images

     $ /usr/local/bin/oc image mirror \
       -f mapping-ic.yaml \
       -a /home/customer-user/.docker/config.json \
       --insecure=true \
       --registry-config /home/customer-user/.docker/config.json \
       --keep-manifest-list=true

  6. Configure the ImageContentSourcePolicy (ICSP) name:

     Set the field 'name' in the file imageContentSourcePolicy.yaml, for example, my-operator-icsp

     Example of a ICSP snippet :

     ---
     apiVersion: operator.openshift.io/v1alpha1
     kind: ImageContentSourcePolicy
     metadata:
         labels:
             operators.openshift.org/catalog: "true"
         name: my-operator-icsp
     spec:
         repositoryDigestMirrors:
         - mirrors:
             - <cluster-domain>:<registry-port>/amq7-amq-interconnect-operator
             source: registry.redhat.io/amq7/amq-interconnect-operator

     Copy to Clipboard Toggle word wrap

  7. Apply the policy (ICSP) file :

     $ /usr/local/bin/oc create -f imageContentSourcePolicy.yaml

     After you apply this file, all cluster nodes are reset automatically. You can check the nodes status using oc get nodes or in the OpenShift console by navigating to Compute Nodes.

     Note

     Make sure all nodes are in Ready state before you continue.

  8. Configure the catalogSource name :

     Set the field name in the catalogSource.yaml file, for example, my-operator-catalog

     Example of a catalogSource.yaml file:

     apiVersion: operators.coreos.com/v1alpha1
     kind: CatalogSource
     metadata:
       name: iib
       namespace: openshift-marketplace
     spec:
       image: <cluster-domain>:<registry-port>/iib:my-operator-iib
       sourceType: grpc

  9. Apply the catalog source configuration to complete the installation of the Red Hat Integration - AMQ Interconnect Operator:

     $ /usr/local/bin/oc apply -f catalogSource.yaml

  10. Make sure the installation is working by deploying a router as described in Section 5.1, “Creating an interior router deployment”
