Chapter 14. Pre-caching images for single-node OpenShift deployments In environments with limited bandwidth where you use the GitOps Zero Touch Provisioning (ZTP) solution to deploy a large number of clusters, you want to avoid downloading all the images that are required for bootstrapping and installing OpenShift Container Platform. The limited bandwidth at remote single-node OpenShift sites can cause long deployment times. The factory-precaching-cli tool allows you to pre-stage servers before shipping them to the remote site for ZTP provisioning. The factory-precaching-cli tool does the following: Downloads the RHCOS rootfs image that is required by the minimal ISO to boot. Creates a partition from the installation disk labelled as data . Formats the disk in xfs. Creates a GUID Partition Table (GPT) data partition at the end of the disk, where the size of the partition is configurable by the tool. Copies the container images required to install OpenShift Container Platform. Copies the container images required by ZTP to install OpenShift Container Platform. Optional: Copies Day-2 Operators to the partition. Important The factory-precaching-cli tool is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope . 14.1. Getting the factory-precaching-cli tool The factory-precaching-cli tool Go binary is publicly available in the {rds-first} tools container image . The factory-precaching-cli tool Go binary in the container image is executed on the server running an RHCOS live image using podman . If you are working in a disconnected environment or have a private registry, you need to copy the image there so you can download the image to the server. Procedure Pull the factory-precaching-cli tool image by running the following command: # podman pull quay.io/openshift-kni/telco-ran-tools:latest Verification To check that the tool is available, query the current version of the factory-precaching-cli tool Go binary: # podman run quay.io/openshift-kni/telco-ran-tools:latest -- factory-precaching-cli -v Example output factory-precaching-cli version 20221018.120852+main.feecf17 14.2. Booting from a live operating system image You can use the factory-precaching-cli tool with to boot servers where only one disk is available and external disk drive cannot be attached to the server. Warning RHCOS requires the disk to not be in use when the disk is about to be written with an RHCOS image. Depending on the server hardware, you can mount the RHCOS live ISO on the blank server using one of the following methods: Using the Dell RACADM tool on a Dell server. Using the HPONCFG tool on a HP server. Using the Redfish BMC API. Note It is recommended to automate the mounting procedure. To automate the procedure, you need to pull the required images and host them on a local HTTP server. Prerequisites You powered up the host. You have network connectivity to the host. Procedure This example procedure uses the Redfish BMC API to mount the RHCOS live ISO. Mount the RHCOS live ISO: Check virtual media status: USD curl --globoff -H "Content-Type: application/json" -H \ "Accept: application/json" -k -X GET --user USD{username_password} \ https://USDBMC_ADDRESS/redfish/v1/Managers/Self/VirtualMedia/1 | python -m json.tool Mount the ISO file as a virtual media: USD curl --globoff -L -w "%{http_code} %{url_effective}\\n" -ku USD{username_password} -H "Content-Type: application/json" -H "Accept: application/json" -d '{"Image": "http://[USDHTTPd_IP]/RHCOS-live.iso"}' -X POST https://USDBMC_ADDRESS/redfish/v1/Managers/Self/VirtualMedia/1/Actions/VirtualMedia.InsertMedia Set the boot order to boot from the virtual media once: USD curl --globoff -L -w "%{http_code} %{url_effective}\\n" -ku USD{username_password} -H "Content-Type: application/json" -H "Accept: application/json" -d '{"Boot":{ "BootSourceOverrideEnabled": "Once", "BootSourceOverrideTarget": "Cd", "BootSourceOverrideMode": "UEFI"}}' -X PATCH https://USDBMC_ADDRESS/redfish/v1/Systems/Self Reboot and ensure that the server is booting from virtual media.

Partitioning the disk To run the full pre-caching process, you have to boot from a live ISO and use the factory-precaching-cli tool from a container image to partition and pre-cache all the artifacts required. A live ISO or RHCOS live ISO is required because the disk must not be in use when the operating system (RHCOS) is written to the device during the provisioning. Single-disk servers can also be enabled with this procedure. Prerequisites You have a disk that is not partitioned. You have access to the quay.io/openshift-kni/telco-ran-tools:latest image. You have enough storage to install OpenShift Container Platform and pre-cache the required images. Procedure Verify that the disk is cleared: # lsblk Example output NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 93.8G 0 loop /run/ephemeral loop1 7:1 0 897.3M 1 loop /sysroot sr0 11:0 1 999M 0 rom /run/media/iso nvme0n1 259:1 0 1.5T 0 disk Erase any file system, RAID or partition table signatures from the device: # wipefs -a /dev/nvme0n1 Example output /dev/nvme0n1: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54 /dev/nvme0n1: 8 bytes were erased at offset 0x1749a955e00 (gpt): 45 46 49 20 50 41 52 54 /dev/nvme0n1: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa Important The tool fails if the disk is not empty because it uses partition number 1 of the device for pre-caching the artifacts. 14.3.1. Creating the partition Once the device is ready, you create a single partition and a GPT partition table. The partition is automatically labelled as data and created at the end of the device. Otherwise, the partition will be overridden by the coreos-installer . Important The coreos-installer requires the partition to be created at the end of the device and to be labelled as data . Both requirements are necessary to save the partition when writing the RHCOS image to the disk. Prerequisites The container must run as privileged due to formatting host devices. You have to mount the /dev folder so that the process can be executed inside the container. Procedure In the following example, the size of the partition is 250 GiB due to allow pre-caching the DU profile for Day 2 Operators. Run the container as privileged and partition the disk: # podman run -v /dev:/dev --privileged \ --rm quay.io/openshift-kni/telco-ran-tools:latest -- \ factory-precaching-cli partition \ 1 -d /dev/nvme0n1 \ 2 -s 250 3 1 Specifies the partitioning function of the factory-precaching-cli tool. 2 Defines the root directory on the disk. 3 Defines the size of the disk in GB. Check the storage information: # lsblk Example output NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 93.8G 0 loop /run/ephemeral loop1 7:1 0 897.3M 1 loop /sysroot sr0 11:0 1 999M 0 rom /run/media/iso nvme0n1 259:1 0 1.5T 0 disk └─nvme0n1p1 259:3 0 250G 0 part Verification You must verify that the following requirements are met: The device has a GPT partition table The partition uses the latest sectors of the device. The partition is correctly labeled as data . Query the disk status to verify that the disk is partitioned as expected: # gdisk -l /dev/nvme0n1 Example output GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/nvme0n1: 3125627568 sectors, 1.5 TiB Model: Dell Express Flash PM1725b 1.6TB SFF Sector size (logical/physical): 512/512 bytes Disk identifier (GUID): CB5A9D44-9B3C-4174-A5C1-C64957910B61 Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 3125627534 Partitions will be aligned on 2048-sector boundaries Total free space is 2601338846 sectors (1.2 TiB) Number Start (sector) End (sector) Size Code Name 1 2601338880 3125627534 250.0 GiB 8300 data 14.3.2. Mounting the partition After verifying that the disk is partitioned correctly, you can mount the device into /mnt . Important It is recommended to mount the device into /mnt because that mounting point is used during GitOps ZTP preparation. Verify that the partition is formatted as xfs : # lsblk -f /dev/nvme0n1 Example output NAME FSTYPE LABEL UUID MOUNTPOINT nvme0n1 └─nvme0n1p1 xfs 1bee8ea4-d6cf-4339-b690-a76594794071 Mount the partition: # mount /dev/nvme0n1p1 /mnt/ Verification Check that the partition is mounted: # lsblk Example output NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 93.8G 0 loop /run/ephemeral loop1 7:1 0 897.3M 1 loop /sysroot sr0 11:0 1 999M 0 rom /run/media/iso nvme0n1 259:1 0 1.5T 0 disk └─nvme0n1p1 259:2 0 250G 0 part /var/mnt 1 1 The mount point is /var/mnt because the /mnt folder in RHCOS is a link to /var/mnt . 14.4. Downloading the images The factory-precaching-cli tool allows you to download the following images to your partitioned server: OpenShift Container Platform images Operator images that are included in the distributed unit (DU) profile for 5G RAN sites Operator images from disconnected registries Note The list of available Operator images can vary in different OpenShift Container Platform releases. 14.4.1. Downloading with parallel workers The factory-precaching-cli tool uses parallel workers to download multiple images simultaneously. You can configure the number of workers with the --parallel or -p option. The default number is set to 80% of the available CPUs to the server. Note Your login shell may be restricted to a subset of CPUs, which reduces the CPUs available to the container. To remove this restriction, you can precede your commands with taskset 0xffffffff , for example: # taskset 0xffffffff podman run --rm quay.io/openshift-kni/telco-ran-tools:latest factory-precaching-cli download --help 14.4.2. Preparing to download the OpenShift Container Platform images To download OpenShift Container Platform container images, you need to know the multicluster engine version. When you use the --du-profile flag, you also need to specify the Red Hat Advanced Cluster Management (RHACM) version running in the hub cluster that is going to provision the single-node OpenShift. Prerequisites You have RHACM and the multicluster engine Operator installed. You partitioned the storage device. You have enough space for the images on the partitioned device. You connected the bare-metal server to the Internet. You have a valid pull secret. Procedure Check the RHACM version and the multicluster engine version by running the following commands in the hub cluster: USD oc get csv -A | grep -i advanced-cluster-management Example output open-cluster-management advanced-cluster-management.v2.6.3 Advanced Cluster Management for Kubernetes 2.6.3 advanced-cluster-management.v2.6.3 Succeeded USD oc get csv -A | grep -i multicluster-engine Example output multicluster-engine cluster-group-upgrades-operator.v0.0.3 cluster-group-upgrades-operator 0.0.3 Pending multicluster-engine multicluster-engine.v2.1.4 multicluster engine for Kubernetes 2.1.4 multicluster-engine.v2.0.3 Succeeded multicluster-engine openshift-gitops-operator.v1.5.7 Red Hat OpenShift GitOps 1.5.7 openshift-gitops-operator.v1.5.6-0.1664915551.p Succeeded multicluster-engine openshift-pipelines-operator-rh.v1.6.4 Red Hat OpenShift Pipelines 1.6.4 openshift-pipelines-operator-rh.v1.6.3 Succeeded To access the container registry, copy a valid pull secret on the server to be installed: Create the .docker folder: USD mkdir /root/.docker Copy the valid pull in the config.json file to the previously created .docker/ folder: USD cp config.json /root/.docker/config.json 1 1 /root/.docker/config.json is the default path where podman checks for the login credentials for the registry. Note If you use a different registry to pull the required artifacts, you need to copy the proper pull secret. If the local registry uses TLS, you need to include the certificates from the registry as well. 14.4.3. Downloading the OpenShift Container Platform images The factory-precaching-cli tool allows you to pre-cache all the container images required to provision a specific OpenShift Container Platform release. Procedure Pre-cache the release by running the following command: # podman run -v /mnt:/mnt -v /root/.docker:/root/.docker --privileged --rm quay.io/openshift-kni/telco-ran-tools -- \ factory-precaching-cli download \ 1 -r 4.17.0 \ 2 --acm-version 2.6.3 \ 3 --mce-version 2.1.4 \ 4 -f /mnt \ 5 --img quay.io/custom/repository 6 1 Specifies the downloading function of the factory-precaching-cli tool. 2 Defines the OpenShift Container Platform release version. 3 Defines the RHACM version. 4 Defines the multicluster engine version. 5 Defines the folder where you want to download the images on the disk. 6 Optional. Defines the repository where you store your additional images. These images are downloaded and pre-cached on the disk.

Pre-caching custom images in disconnected environments The --generate-imageset argument stops the factory-precaching-cli tool after the ImageSetConfiguration custom resource (CR) is generated. This allows you to customize the ImageSetConfiguration CR before downloading any images. After you customized the CR, you can use the --skip-imageset argument to download the images that you specified in the ImageSetConfiguration CR. You can customize the ImageSetConfiguration CR in the following ways: Add Operators and additional images Remove Operators and additional images Change Operator and catalog sources to local or disconnected registries Procedure Pre-cache the images: # podman run -v /mnt:/mnt -v /root/.docker:/root/.docker --privileged --rm quay.io/openshift-kni/telco-ran-tools:latest -- factory-precaching-cli download \ 1 -r 4.17.0 \ 2 --acm-version 2.6.3 \ 3 --mce-version 2.1.4 \ 4 -f /mnt \ 5 --img quay.io/custom/repository 6 --du-profile -s \ 7 --generate-imageset 8 1 Specifies the downloading function of the factory-precaching-cli tool. 2 Defines the OpenShift Container Platform release version. 3 Defines the RHACM version. 4 Defines the multicluster engine version. 5 Defines the folder where you want to download the images on the disk. 6 Optional.

If defined, it overrides the spec.clusterImageSetNameRef at the site level. 14.5.1. Understanding the clusters.ignitionConfigOverride field The clusters.ignitionConfigOverride field adds a configuration in Ignition format during the GitOps ZTP discovery stage. The configuration includes systemd services in the ISO mounted in virtual media. This way, the scripts are part of the discovery RHCOS live ISO and they can be used to load the Assisted Installer (AI) images. systemd services The systemd services are var-mnt.mount and precache-images.services . The precache-images.service depends on the disk partition to be mounted in /var/mnt by the var-mnt.mount unit. The service calls a script called extract-ai.sh . extract-ai.sh The extract-ai.sh script extracts and loads the required images from the disk partition to the local container storage. When the script finishes successfully, you can use the images locally. agent-fix-bz1964591 The agent-fix-bz1964591 script is a workaround for an AI issue. To prevent AI from removing the images, which can force the agent.service to pull the images again from the registry, the agent-fix-bz1964591 script checks if the requested container images exist. 14.5.2. Understanding the nodes.installerArgs field The nodes.installerArgs field allows you to configure how the coreos-installer utility writes the RHCOS live ISO to disk. You need to indicate to save the disk partition labeled as data because the artifacts saved in the data partition are needed during the OpenShift Container Platform installation stage. The extra parameters are passed directly to the coreos-installer utility that writes the live RHCOS to disk. On the reboot, the operating system starts from the disk. You can pass several options to the coreos-installer utility: OPTIONS: ... -u, --image-url <URL> Manually specify the image URL -f, --image-file <path> Manually specify a local image file -i, --ignition-file <path> Embed an Ignition config from a file -I, --ignition-url <URL> Embed an Ignition config from a URL ... --save-partlabel <lx>... Save partitions with this label glob --save-partindex <id>... Save partitions with this number or range ... --insecure-ignition Allow Ignition URL without HTTPS or hash 14.5.3. Understanding the nodes.ignitionConfigOverride field Similarly to clusters.ignitionConfigOverride , the nodes.ignitionConfigOverride field allows the addition of configurations in Ignition format to the coreos-installer utility, but at the OpenShift Container Platform installation stage. When the RHCOS is written to disk, the extra configuration included in the GitOps ZTP discovery ISO is no longer available. During the discovery stage, the extra configuration is stored in the memory of the live OS. Note At this stage, the number of container images extracted and loaded is bigger than in the discovery stage. Depending on the OpenShift Container Platform release and whether you install the Day-2 Operators, the installation time can vary. At the installation stage, the var-mnt.mount and precache-ocp.services systemd services are used. precache-ocp.service The precache-ocp.service depends on the disk partition to be mounted in /var/mnt by the var-mnt.mount unit. The precache-ocp.service service calls a script called extract-ocp.sh . Important To extract all the images before the OpenShift Container Platform installation, you must execute precache-ocp.service before executing the machine-config-daemon-pull.service and nodeip-configuration.service services. extract-ocp.sh The extract-ocp.sh script extracts and loads the required images from the disk partition to the local container storage. When you commit the SiteConfig and optional PolicyGenerator or PolicyGenTemplate custom resources (CRs) to the Git repo that Argo CD is monitoring, you can start the GitOps ZTP workflow by syncing the CRs with the hub cluster. 14.6. Troubleshooting a "Rendered catalog is invalid" error When you download images by using a local or disconnected registry, you might see the The rendered catalog is invalid error. This means that you are missing certificates of the new registry you want to pull content from. Note The factory-precaching-cli tool image is built on a UBI RHEL image. Certificate paths and locations are the same on RHCOS.
