Create Local Repo

Use the cw-clusterctl repos command to download ISO images of the installation DVDs for RHEL-family systems from their respective websites and import them into the ClusterWareAI ™ software as repos. See Supported Distributions and Features for a list of supported RHEL systems.

For example, the following command creates a repo that references the Rocky-8.7-x86_64-dvd1 ISO. The --wait option ensures the ISO is fully mounted:

cw-clusterctl repos --wait create name=Rocky8repo iso=@Rocky-8.7-x86_64-dvd1.iso

Tip

You can also create a repo when creating a boot configuration by referencing an ISO. See Create Boot Configuration for details.

Once the upload completes, the ISO is automatically forwarded to all head nodes and is locally mounted on each. Use the list subcommand to view repository details:

[cwadmin@virthead]$ cw-clusterctl repos -i Rocky8repo ls -l

    urls
      <BASE_URL>/isomount/Rocky8repo/BaseOS/
      <BASE_URL>/isomount/Rocky8repo/AppStream/

The ClusterWareAI platform displays URLs for the repositories identified on the ISO. For example, there is a repository in the root of the uploaded Rocky-8 ISO, accessible at <BASE_URL>/isomount/Rocky8repo/BaseOS/. The <BASE_URL> tag is used as a placeholder to signify that any head node can provide access. When using such a URL, replace the <BASE_URL> with the actual head node's base URL. For example, http://10.20.30.30/api/v1/isomount/Rocky8repo/BaseOS/<target-file>.

The ISO can also be downloaded using the cw-clusterctl command:

cw-clusterctl repos -i Rocky8repo download iso

Just like URL defined repos, repos created using ISOs can be referenced in distros. See Creating Images and Using ISO Releases for details about using repos and distros to create compute node images.
