Prepare for local clusters

Before you deploy a local cluster, complete preparation steps such as adding domains to your allowlist and disabling your OS firewall. A local cluster runs mappings in advanced mode.

Before you deploy a local cluster, be sure you've completed the following preparation steps:

•Add the following domains to the outbound allowlist for your local cluster and ensure that they are reachable from the Secure Agent machine:

artifacthub.informaticacloud.com
rhui3.<region>.<cloud>.ce.redhat.com (RHEL 8.x ONLY)

Example of the last domain above: rhui3.us-west-2.aws.ce.redhat.com

The local cluster needs to access these domains to fetch artifacts such as machine images, and to access sources and targets.

•Disable the OS firewall by running this command on the Secure Agent machine:

sudo systemctl disable firewalld

Disabling the OS firewall prevents disruption of jobs sent to the local cluster.
