Chapter 14. Converting a connected cluster to a disconnected cluster There might be some scenarios where you need to convert your OpenShift Container Platform cluster from a connected cluster to a disconnected cluster. A disconnected cluster, also known as a restricted cluster, does not have an active connection to the internet. As such, you must mirror the contents of your registries and installation media. You can create this mirror registry on a host that can access both the internet and your closed network, or copy images to a device that you can move across network boundaries. This topic describes the general process for converting an existing, connected cluster into a disconnected cluster. 14.1. About the mirror registry You can mirror the images that are required for OpenShift Container Platform installation and subsequent product updates to a container mirror registry such as Red Hat Quay, JFrog Artifactory, Sonatype Nexus Repository, or Harbor. If you do not have access to a large-scale container registry, you can use the mirror registry for Red Hat OpenShift , a small-scale container registry included with OpenShift Container Platform subscriptions. You can use any container registry that supports Docker v2-2 , such as Red Hat Quay, the mirror registry for Red Hat OpenShift , Artifactory, Sonatype Nexus Repository, or Harbor. Regardless of your chosen registry, the procedure to mirror content from Red Hat hosted sites on the internet to an isolated image registry is the same. After you mirror the content, you configure each cluster to retrieve this content from your mirror registry. Important The OpenShift image registry cannot be used as the target registry because it does not support pushing without a tag, which is required during the mirroring process. If choosing a container registry that is not the mirror registry for Red Hat OpenShift , it must be reachable by every machine in the clusters that you provision. If the registry is unreachable, installation, updating, or normal operations such as workload relocation might fail. For that reason, you must run mirror registries in a highly available way, and the mirror registries must at least match the production availability of your OpenShift Container Platform clusters. When you populate your mirror registry with OpenShift Container Platform images, you can follow two scenarios. If you have a host that can access both the internet and your mirror registry, but not your cluster nodes, you can directly mirror the content from that machine. This process is referred to as connected mirroring . If you have no such host, you must mirror the images to a file system and then bring that host or removable media into your restricted environment. This process is referred to as disconnected mirroring . For mirrored registries, to view the source of pulled images, you must review the Trying to access log entry in the CRI-O logs. Other methods to view the image pull source, such as using the crictl images command on a node, show the non-mirrored image name, even though the image is pulled from the mirrored location. Note Red Hat does not test third party registries with OpenShift Container Platform. 14.2. Prerequisites The oc client is installed. A running cluster. An installed mirror registry, which is a container image registry that supports Docker v2-2 in the location that will host the OpenShift Container Platform cluster, such as one of the following registries: Red Hat Quay JFrog Artifactory Sonatype Nexus Repository Harbor If you have an subscription to Red Hat Quay, see the documentation on deploying Red Hat Quay for proof-of-concept purposes or by using the Quay Operator . The mirror repository must be configured to share images. For example, a Red Hat Quay repository requires Organizations in order to share images. Access to the internet to obtain the necessary container images. 14.3. Preparing the cluster for mirroring Before disconnecting your cluster, you must mirror, or copy, the images to a mirror registry that is reachable by every node in your disconnected cluster. In order to mirror the images, you must prepare your cluster by: Adding the mirror registry certificates to the list of trusted CAs on your host. Creating a .dockerconfigjson file that contains your image pull secret, which is from the cloud.openshift.com token. Procedure Configuring credentials that allow image mirroring: Add the CA certificate for the mirror registry, in the simple PEM or DER file formats, to the list of trusted CAs. For example: USD cp </path/to/cert.crt> /usr/share/pki/ca-trust-source/anchors/ where, </path/to/cert.crt> Specifies the path to the certificate on your local file system. Update the CA trust. For example, in Linux: USD update-ca-trust Extract the .dockerconfigjson file from the global pull secret: USD oc extract secret/pull-secret -n openshift-config --confirm --to=. Example output .dockerconfigjson Edit the .dockerconfigjson file to add your mirror registry and authentication credentials and save it as a new file: {"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}},"<registry>:<port>/<namespace>/":{"auth":"<token>"}}} where: <local_registry> Specifies the registry domain name, and optionally the port, that your mirror registry uses to serve content. auth Specifies the base64-encoded user name and password for your mirror registry. <registry>:<port>/<namespace> Specifies the mirror registry details. <token> Specifies the base64-encoded username:password for your mirror registry. For example: USD {"auths":{"cloud.openshift.com":{"auth":"b3BlbnNoaWZ0Y3UjhGOVZPT0lOMEFaUjdPUzRGTA==","email":"user@example.com"}, "quay.io":{"auth":"b3BlbnNoaWZ0LXJlbGVhc2UtZGOVZPT0lOMEFaUGSTd4VGVGVUjdPUzRGTA==","email":"user@example.com"}, "registry.connect.redhat.com"{"auth":"NTE3MTMwNDB8dWhjLTFEZlN3VHkxOSTd4VGVGVU1MdTpleUpoYkdjaUailA==","email":"user@example.com"}, "registry.redhat.io":{"auth":"NTE3MTMwNDB8dWhjLTFEZlN3VH3BGSTd4VGVGVU1MdTpleUpoYkdjaU9fZw==","email":"user@example.com"}, "registry.svc.ci.openshift.org":{"auth":"dXNlcjpyWjAwWVFjSEJiT2RKVW1pSmg4dW92dGp1SXRxQ3RGN1pwajJhN1ZXeTRV"},"my-registry:5000/my-namespace/":{"auth":"dXNlcm5hbWU6cGFzc3dvcmQ="}}} 14.4. Mirroring the images After the cluster is properly configured, you can mirror the images from your external repositories to the mirror repository. Procedure Mirror the Operator Lifecycle Manager (OLM) images: USD oc adm catalog mirror registry.redhat.io/redhat/redhat-operator-index:v{product-version} <mirror_registry>:<port>/olm -a <reg_creds> where: product-version Specifies the tag that corresponds to the version of OpenShift Container Platform to install, such as 4.8 . mirror_registry Specifies the fully qualified domain name (FQDN) for the target registry and namespace to mirror the Operator content to, where <namespace> is any existing namespace on the registry. reg_creds Specifies the location of your modified .dockerconfigjson file. For example: USD oc adm catalog mirror registry.redhat.io/redhat/redhat-operator-index:v4.8 mirror.registry.com:443/olm -a ./.dockerconfigjson --index-filter-by-os='.*' Mirror the content for any other Red Hat-provided Operator: USD oc adm catalog mirror <index_image> <mirror_registry>:<port>/<namespace> -a <reg_creds> where: index_image Specifies the index image for the catalog that you want to mirror. mirror_registry Specifies the FQDN for the target registry and namespace to mirror the Operator content to, where <namespace> is any existing namespace on the registry. reg_creds Optional: Specifies the location of your registry credentials file, if required. For example: USD oc adm catalog mirror registry.redhat.io/redhat/community-operator-index:v4.8 mirror.registry.com:443/olm -a ./.dockerconfigjson --index-filter-by-os='.*' Mirror the OpenShift Container Platform image repository: USD oc adm release mirror -a .dockerconfigjson --from=quay.io/openshift-release-dev/ocp-release:v<product-version>-<architecture> --to=<local_registry>/<local_repository> --to-release-image=<local_registry>/<local_repository>:v<product-version>-<architecture> where: product-version Specifies the tag that corresponds to the version of OpenShift Container Platform to install, such as 4.8.15-x86_64 . architecture Specifies the type of architecture for your server, such as x86_64 . local_registry Specifies the registry domain name for your mirror repository. local_repository Specifies the name of the repository to create in your registry, such as ocp4/openshift4 . For example: USD oc adm release mirror -a .dockerconfigjson --from=quay.io/openshift-release-dev/ocp-release:4.8.15-x86_64 --to=mirror.registry.com:443/ocp/release --to-release-image=mirror.registry.com:443/ocp/release:4.8.15-x86_64 Example output info: Mirroring 109 images to mirror.registry.com/ocp/release ... mirror.registry.com:443/ ocp/release manifests: sha256:086224cadce475029065a0efc5244923f43fb9bb3bb47637e0aaf1f32b9cad47 -> 4.8.15-x86_64-thanos sha256:0a214f12737cb1cfbec473cc301aa2c289d4837224c9603e99d1e90fc00328db -> 4.8.15-x86_64-kuryr-controller sha256:0cf5fd36ac4b95f9de506623b902118a90ff17a07b663aad5d57c425ca44038c -> 4.8.15-x86_64-pod sha256:0d1c356c26d6e5945a488ab2b050b75a8b838fc948a75c0fa13a9084974680cb -> 4.8.15-x86_64-kube-client-agent ..... sha256:66e37d2532607e6c91eedf23b9600b4db904ce68e92b43c43d5b417ca6c8e63c mirror.registry.com:443/ocp/release:4.5.41-multus-admission-controller sha256:d36efdbf8d5b2cbc4dcdbd64297107d88a31ef6b0ec4a39695915c10db4973f1 mirror.registry.com:443/ocp/release:4.5.41-cluster-kube-scheduler-operator sha256:bd1baa5c8239b23ecdf76819ddb63cd1cd6091119fecdbf1a0db1fb3760321a2 mirror.registry.com:443/ocp/release:4.5.41-aws-machine-controllers info: Mirroring completed in 2.02s (0B/s) Success Update image: mirror.registry.com:443/ocp/release:4.5.41-x86_64 Mirror prefix: mirror.registry.com:443/ocp/release Mirror any other registries, as needed: USD oc image mirror <online_registry>/my/image:latest <mirror_registry> Additional information For more information about mirroring Operator catalogs, see Mirroring an Operator catalog . For more information about the oc adm catalog mirror command, see the OpenShift CLI administrator command reference . 14.5. Configuring the cluster for the mirror registry After creating and mirroring the images to the mirror registry, you must modify your cluster so that pods can pull images from the mirror registry. You must: Add the mirror registry credentials to the global pull secret. Add the mirror registry server certificate to the cluster. Create an ImageContentSourcePolicy custom resource (ICSP), which associates the mirror registry with the source registry. Add mirror registry credential to the cluster global pull-secret: USD oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=<pull_secret_location> 1 1 Provide the path to the new pull secret file. For example: USD oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=.mirrorsecretconfigjson Add the CA-signed mirror registry server certificate to the nodes in the cluster: Create a config map that includes the server certificate for the mirror registry USD oc create configmap <config_map_name> --from-file=<mirror_address_host>..<port>=USDpath/ca.crt -n openshift-config For example: S oc create configmap registry-config --from-file=mirror.registry.com..443=/root/certs/ca-chain.cert.pem -n openshift-config Use the config map to update the image.config.openshift.io/cluster custom resource (CR). OpenShift Container Platform applies the changes to this CR to all nodes in the cluster: USD oc patch image.config.openshift.io/cluster --patch '{"spec":{"additionalTrustedCA":{"name":"<config_map_name>"}}}' --type=merge For example: USD oc patch image.config.openshift.io/cluster --patch '{"spec":{"additionalTrustedCA":{"name":"registry-config"}}}' --type=merge Create an ICSP to redirect container pull requests from the online registries to the mirror registry: Create the ImageContentSourcePolicy custom resource: apiVersion: operator.openshift.io/v1alpha1 kind: ImageContentSourcePolicy metadata: name: mirror-ocp spec: repositoryDigestMirrors: - mirrors: - mirror.registry.com:443/ocp/release 1 source: quay.io/openshift-release-dev/ocp-release 2 - mirrors: - mirror.registry.com:443/ocp/release source: quay.io/openshift-release-dev/ocp-v4.0-art-dev 1 Specifies the name of the mirror image registry and repository. 2 Specifies the online registry and repository containing the content that is mirrored. Create the ICSP object: USD oc create -f registryrepomirror.yaml Example output imagecontentsourcepolicy.operator.openshift.io/mirror-ocp created OpenShift Container Platform applies the changes to this CR to all nodes in the cluster. Verify that the credentials, CA, and ICSP for mirror registry were added: Log into a node: USD oc debug node/<node_name> Set /host as the root directory within the debug shell: sh-4.4# chroot /host Check the config.json file for the credentials: sh-4.4# cat /var/lib/kubelet/config.json Example output {"auths":{"brew.registry.redhat.io":{"xx=="},"brewregistry.stage.redhat.io":{"auth":"xxx=="},"mirror.registry.com:443":{"auth":"xx="}}} 1 1 Ensure that the mirror registry and credentials are present. Change to the certs.d directory sh-4.4# cd /etc/docker/certs.d/ List the certificates in the certs.d directory: sh-4.4# ls Example output 1 Ensure that the mirror registry is in the list. Check that the ICSP added the mirror registry to the registries.conf file: sh-4.4# cat /etc/containers/registries.conf Example output unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] [[registry]] prefix = "" location = "quay.io/openshift-release-dev/ocp-release" mirror-by-digest-only = true [[registry.mirror]] location = "mirror.registry.com:443/ocp/release" [[registry]] prefix = "" location = "quay.io/openshift-release-dev/ocp-v4.0-art-dev" mirror-by-digest-only = true [[registry.mirror]] location = "mirror.registry.com:443/ocp/release" The registry.mirror parameters indicate that the mirror registry is searched before the original registry. Exit the node. sh-4.4# exit 14.6. Ensure applications continue to work Before disconnecting the cluster from the network, ensure that your cluster is working as expected and all of your applications are working as expected. Procedure Use the following commands to check the status of your cluster: Ensure your pods are running: USD oc get pods --all-namespaces Example output NAMESPACE NAME READY STATUS RESTARTS AGE kube-system apiserver-watcher-ci-ln-47ltxtb-f76d1-mrffg-master-0 1/1 Running 0 39m kube-system apiserver-watcher-ci-ln-47ltxtb-f76d1-mrffg-master-1 1/1 Running 0 39m kube-system apiserver-watcher-ci-ln-47ltxtb-f76d1-mrffg-master-2 1/1 Running 0 39m openshift-apiserver-operator openshift-apiserver-operator-79c7c646fd-5rvr5 1/1 Running 3 45m openshift-apiserver apiserver-b944c4645-q694g 2/2 Running 0 29m openshift-apiserver apiserver-b944c4645-shdxb 2/2 Running 0 31m openshift-apiserver apiserver-b944c4645-x7rf2 2/2 Running 0 33m ...

Disconnect the cluster from the network After mirroring all the required repositories and configuring your cluster to work as a disconnected cluster, you can disconnect the cluster from the network. Note The Insights Operator is degraded when the cluster loses its Internet connection. You can avoid this problem by temporarily disabling the Insights Operator until you can restore it. 14.8. Restoring a degraded Insights Operator Disconnecting the cluster from the network necessarily causes the cluster to lose the Internet connection. The Insights Operator becomes degraded because it requires access to Red Hat Insights . This topic describes how to recover from a degraded Insights Operator. Procedure Edit your .dockerconfigjson file to remove the cloud.openshift.com entry, for example: "cloud.openshift.com":{"auth":"<hash>","email":"user@example.com"} Save the file. Update the cluster secret with the edited .dockerconfigjson file: USD oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=./.dockerconfigjson Verify that the Insights Operator is no longer degraded: USD oc get co insights Example output NAME VERSION AVAILABLE PROGRESSING DEGRADED SINCE insights 4.5.41 True False False 3d 14.9. Restoring the network If you want to reconnect a disconnected cluster and pull images from online registries, delete the cluster's ImageContentSourcePolicy (ICSP) objects. Without the ICSP, pull requests to external registries are no longer redirected to the mirror registry. Procedure View the ICSP objects in your cluster: USD oc get imagecontentsourcepolicy Example output NAME AGE mirror-ocp 6d20h ocp4-index-0 6d18h qe45-index-0 6d15h Delete all the ICSP objects you created when disconnecting your cluster: USD oc delete imagecontentsourcepolicy <icsp_name> <icsp_name> <icsp_name> For example: USD oc delete imagecontentsourcepolicy mirror-ocp ocp4-index-0 qe45-index-0 Example output imagecontentsourcepolicy.operator.openshift.io "mirror-ocp" deleted imagecontentsourcepolicy.operator.openshift.io "ocp4-index-0" deleted imagecontentsourcepolicy.operator.openshift.io "qe45-index-0" deleted Wait for all the nodes to restart and return to the READY status and verify that the registries.conf file is pointing to the original registries and not the mirror registries: Log into a node: USD oc debug node/<node_name> Set /host as the root directory within the debug shell: sh-4.4# chroot /host Examine the registries.conf file: sh-4.4# cat /etc/containers/registries.conf Example output unqualified-search-registries = ["registry.access.redhat.com", "docker.io"] 1 1 The registry and registry.mirror entries created by the ICSPs you deleted are removed.
