MicroShift

Quick list of steps to deploy MicroShift on RHEL 9.

1. Add the necessary repo’s

   Note

   My example shows OCP v4.19 on RHEL v9.6.

   sudo subscription-manager repos \
     --enable rhocp-4.19-for-rhel-9-x86_64-rpms \
     --enable fast-datapath-for-rhel-9-x86_64-rpms
   

2. Install MicroShift and OpenShift client tools.

   sudo dnf install microshift openshift-clients
   

3. Update firewall for default networks and ports

   sudo firewall-cmd --add-source=10.42.0.0/16 --permanent
   sudo firewall-cmd --add-source=169.254.169.1 --permanent
   sudo firewall-cmd --add-port=6443/tcp --permanent
   sudo firewall-cmd --add-port=443/tcp --permanent
