Simple guide

This page is a super easy to follow, "TL;DR", minimum list of commands to get a ROSA cluster deployed. This will work great for this workshop, though more attention should be paid for clusters to be used in production.

Assumptions#

The steps on this page assume you have completed the prerequisites in the Setup section.

Create account roles#

Run once per AWS account, per y-stream OpenShift version:

rosa create account-roles --mode auto --yes

Deploy the cluster#

Choose the CLI or the UI method.

ROSA CLI#

  1. Create the cluster with the default configuration. Just choose a cluster name.

    rosa create cluster --cluster-name <cluster-name> --sts --mode auto --yes

  2. Check the status.

    rosa list clusters

OCM UI#

  1. Create OCM Role (only once per AWS account)

    rosa create ocm-role --mode auto --admin --yes

  2. Create OCM User Role (only once per AWS account)

    rosa create user-role --mode auto --yes

  3. Use the OCM UI to select your AWS account, cluster options, and deploy.

  4. The status will update in the UI.
