Prerequisites to install by using YAML or OLM

A few operators are needed to install InfoScale by using OLM. As air gapped/restricted networks are disconnected from the internet, operators must be mirrored to local registry. For mirroring, it requires a host having internet as well as local registry connection, named mirror-host.

Complete the following steps on the mirror-host where ${LOCAL_REGISTRY} is accessible. For others, see https://docs.openshift.com/container-platform/4.11/installing/disconnected_install/installing-mirroring-disconnected.html

Note:

In the following steps, ${LOCAL_REGISTRY} is on the same network. LOCAL_REGISTRY is a system connected to the mirror-host but disconnected from Internet,and has a registry setup.

  1. Run the following command to set variables.

    export LOCAL_REGISTRY=<local_registry_host_name>:<local_registry_host_port>

  2. Run the following commands to download and extract the latest oc-mirror plugin on the mirror host.

    wget -4 https://mirror.openshift.com/pub/openshift-v4/x86_64/clients/ocp/latest/oc-mirror.tar.gz

    tar -xvf oc-mirror.tar.gz -C /usr/local/bin/

    chmod 750 /usr/local/bin/oc-mirror

  3. Download YAML_8.0.220.tar.gz from the Veritas Download Centre.
  4. Extract YAML_8.0.220.tar.gz . A folder YAML/OpenShift/air-gapped is created and all files required for installation are available in the folder.
  5. Run the following commands to login to registries.

    podman login registry.redhat.io

    podman login registry.connect.redhat.com

    podman login ${LOCAL_REGISTRY}

  6. Run oc mirror list operators --catalog <CATALOG> --package <OPERATOR> to update operators.packages.channels.name in YAML/OpenShift/air-gapped-systems/imageset-config.yaml.
  7. Edit imageset-config.yaml to
    • Replace ${LOCAL_REGISTRY} with <local_registry_host_name>:<local_registry_host_port>.

    • Replace ${OCP_RELEASE} with the OCP version.

    • Replace ${OSVER} with Operating system version of the worker node.

    • Replace ${KERNVER} with Kernel version of the worker node.

  8. Run the following commands on the mirror host to mirror operators.

    cd YAML/OpenShift/air-gapped-systems

    oc mirror --config=./imageset-config.yaml docker://${LOCAL_REGISTRY}/operators --continue-on-error

    Review output as under.

    Rendering catalog image "registry.lab.ocp.lan:5000
      /operators1/redhat/certified-operator-index:v4.10" 
                                with file-based catalog
    Rendering catalog image "registry.lab.ocp.lan:5000
      /operators1/redhat/redhat-operator-index:v4.10" 
                              with file-based catalog
    Writing image mapping to 
     oc-mirror-workspace/results-1669176953/mapping.txt
    Writing CatalogSource manifests to 
                oc-mirror-workspace/results-1669176953
    Writing ICSP manifests to 
              oc-mirror-workspace/results-1669176953

    Note:

    Here, registry.lab.ocp.lan is the local registry and 5000 is an indicative port number.

  9. Optionally, Update oc-mirror-workspace/results-1669176953/catalogSource-redhat-operator-index.yaml and - oc-mirror-workspace/results-1669176953/catalogSource-certified-operator-index.yaml .
  10. Run the following command to copy oc-mirror-workspace to the bastion node.

    scp -r oc-mirror-workspace ocp-svc:~/

  11. Run the following command on the bastion node to set disableAllDefaultSources: true. This disables all sources for the default catalogs.

    oc patch OperatorHub cluster --type json -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]'

  12. Run the following commands on the bastion node to deploy the image content source policy and catalog source.

    oc create -f oc-mirror-workspace/results-1669176953/imageContentSourcePolicy.yaml

    oc create -f oc-mirror-workspace/results-1669176953/catalogSource-redhat-operator-index.yaml

    oc create -f oc-mirror-workspace/results-1669176953/catalogSource-certified-operator-index.yaml

  13. Run the following commands on the bastion node to verify whether the resources are created successfully.

    oc get catalogsource -n openshift-marketplace

    oc get pods -n openshift-marketplace

    oc get packagemanifest -n openshift-marketplace

  14. Login to the OpenShift web console and check whether the mirrored operators are displayed in Operators > OperatorHub as under
  15. On the mirror host, Download, unzip, and untar tools_8.0.220.tar.gz from theVeritas Download Center. After you unzip and untar, tools/setup_vtas_registry.sh is automatically created.
  16. Run the following commands on the mirror host.

    cd tools

    OS_VER=<OS Version> # eg: 'rhel8.4'

    KERNEL=<Kernel Version of worker>' # eg: 4.18.0-305.45.1.el8_4.x86_64'

    ./setup_vtas_registry.sh --airgap -o $OS_VER -k $KERNEL

    A folder infoscale_operand_images.tar is automatically created.

  17. Copy infoscale_operand_images.tar from the mirror host to the bastion node.
  18. Run the following commands to load infoscale images onto local registry from bastion node

    OS_VER=<OS Version> # eg: 'rhel8.4'

    KERNEL=<Kernel Version of worker>' # eg: 4.18.0-305.45.1.el8_4.x86_64'

    podman login ${LOCAL_REGISTRY}

    ./setup_vtas_registry.sh --airgap -o $OS_VER -k $KERNEL \ -c ${LOCAL_REGISTRY}/veritas -t infoscale_operand_images.tar
