Air-gapped / disconnected

Some notes how you can setup a air-gapped / disconnected OpenShift 4 cluster with hetzner-ocp4

Create ait-gapped configuration file:

To distiguish online & offline configuration file, let's create the file cluster-air-gapped.yml

Be sure that the following lines are defined in your configuration file:

network_forward_mode: "open"
vn_subnet: "192.168.50.0"

Prepare the installation host

To be sure that all packages are installed accordingly prepare your node:

# ansible-navigator run ./ansible/01-prepare-host.yml -e @cluster-air-gapped.yml

Create network

# ansible-navigator run ./ansible/02-create-cluster.yml \
  -e @cluster-air-gapped.yml \
  --tags network

Setup mirror registry on kvm-host

Using Red Hat Mirror Registry

https://docs.openshift.com/container-platform/latest/installing/disconnected_install/installing-mirroring-creating-registry.html

Prepare your node and create certificates for the registry and other stuff.

# ansible-navigator run ./docs/air-gapped/prep-mirror-registry.yaml -e @cluster-air-gapped.yml

Download and extract the mirror-registry binary: (This is currently not done via Ansible)

mkdir ~/mirror
cd ~/mirror
curl -L -O https://developers.redhat.com/content-gateway/rest/mirror/pub/openshift-v4/clients/mirror-registry/latest/mirror-registry.tar.gz
tar -xzvf mirror-registry.tar.gz

Create the Mirror Registry

./mirror-registry install -v \
  --quayHostname host.compute.local:5000 \
  --quayRoot /var/lib/libvirt/images/mirror-registry/quay/ \
  --ssh-key /root/.ssh/id_rsa \
  --sslKey /var/lib/libvirt/images/mirror-registry/certs/registry.key \
  --sslCert /var/lib/libvirt/images/mirror-registry/certs/registry.crt \
  --initPassword r3dh4t\!1

Login into the created registry and store the authentication information

podman login --username init --password r3dh4t\!1 \
  --authfile mirror-registry-pullsecret.json \
  host.compute.local:5000

Download Red Hat pull secret

Download Red Hat pull secret from cloud.redhat.com and store it in redhat-pullsecret.json

Concat redhat pull secret and the authfile created above

Store the result in ~/.docker/config.json

mkdir ~/.docker
jq -s '{"auths": ( .[0].auths + .[1].auths ) }' \ 
    mirror-registry-pullsecret.json \
    <path-to-your-redhat-pullsecret> > ~/.docker/config.json

Download OC Client

Download oc client, oc mirror pluging (and other stuff)

ansible-navigator run ./ansible/02-create-cluster.yml -e @cluster-air-gapped.yml --tags download-openshift-artifacts

Mirror Images using oc-mirror plugin

Initialize the mirror configuration:

oc mirror init --registry host.compute.local:5000/mirror/oc-mirror-metadata > imageset-config.yaml

This will create a configuration file like the following:

kind: ImageSetConfiguration
apiVersion: mirror.openshift.io/v1alpha2
storageConfig:
  registry:
    imageURL: host.compute.local:5000/mirror/oc-mirror-metadata
    skipTLS: false
mirror:
  platform:
    channels:
    - name: stable-4.12
      type: ocp
  operators: []
  additionalImages: []
  helm: {}

You can add additional Operators, Images or Charts.

Download Images to local disk

I am downloading it to the local disk first ... just for fun

mkdir ~/mirror-data/
oc mirror --config=./imageset-config.yaml file:///root/mirror-data/

This will download everything into your folder:

du -sh ~/mirror-data
21G	~/mirror-data

Note: If you do not want to download everything locally, your can push them directly into the mirror registry by using docker://registry.example:5000 instead of file://...

Push everything into the mirror registry

oc mirror --from=./mirror_seq1_000000.tar docker://host.compute.local:5000

Extract `openshift-install` command

oc adm release extract -a  ~/.docker/config.json \
  --command=openshift-install \
  "host.compute.local:5000/openshift/release-images:$(oc version -o json | jq -r .releaseClientVersion )-x86_64"

Update cluster.yml

Add install_config_additionalTrustBundle and install_config_imageContentSources into cluster.yml.

# Path to extracted openshift-install command
openshift_install_command: "/root/hetzner-ocp4/openshift-install"
install_config_additionalTrustBundle: |

Sync Operatorhub

Not all operators support disconnected environments: Red Hat Operators Supported in Disconnected Mode

How to sync operators with OpenShift 4.8: official documentation

Disable default catalog source

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

run index

podman run -p50051:50051 \
  --authfile $LOCAL_SECRET_JSON \
  registry.redhat.io/redhat/redhat-operator-index:v4.8

Export names

Install grpcurl https://github.com/fullstorydev/grpcurl/releases

grpcurl -plaintext localhost:50051 api.Registry/ListPackages > packages.out

Sync Index

opm index prune \
    -f registry.redhat.io/redhat/redhat-operator-index:v4.10 \
    -p codeready-workspaces2 \
    -t ${LOCAL_REGISTRY}/olm/redhat-operator-index:v4.10


podman push ${LOCAL_REGISTRY}/olm/redhat-operator-index:v4.10

oc adm catalog mirror \
  ${LOCAL_REGISTRY}/olm/redhat-operator-index:v4.10 \
  ${LOCAL_REGISTRY}/olm \
  --manifests-only \
  -a ${LOCAL_SECRET_JSON}

If `storage_nfs: true`

Copy nfs-client-provisioner image

oc image mirror -a ${LOCAL_SECRET_JSON} \
  k8s.gcr.io/sig-storage/nfs-subdir-external-provisioner:v4.0.2 \
  ${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:nfs-client-provisioner-latest

or with skopoe:

skopeo copy \
  --authfile=${LOCAL_SECRET_JSON} \
  docker://quay.io/external_storage/nfs-client-provisioner:latest \
  docker://${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:nfs-client-provisioner-latest

Patch nfs provisioner deployment

  oc patch -n openshift-nfs-provisioner deployment.apps/nfs-client-provisioner \
    --patch "{\"spec\":{\"template\":{\"spec\":{\"containers\":[{\"name\":\"nfs-client-provisioner\",\"image\":\"${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:nfs-client-provisioner-latest\"}]}}}}"

Sample operator

Documentation: Using Samples Operator imagestreams with alternate or mirrored registries

Warning: Sync all examples takes a while!

Remember: A lot of examples need a git repo to, don't forget to sync those! To get an repo overview: oc get is -n openshift -o json | jq -r '.items[].spec.tags[].annotations.sampleRepo' | sort -u

# Get a list
# oc get is -n openshift -o json | jq -r '.items[].spec.tags[].from.name' | grep registry.redhat.io

How to skip imagestreams

Maybe checkout the missing imagestreams bevor: oc describe configs.samples.operator.openshift.io/cluster
