Module 0 — Access Your ROSA Cluster

In this first lab you will log into your pre-provisioned Red Hat OpenShift Service on AWS (ROSA) cluster, verify your CLI tools are working, and review the overall workshop architecture before getting started.

Your cluster was provisioned before the workshop began — you do not need to create it. This lets you spend your time on what matters: deploying AI infrastructure and building applications.

Estimated time: 20 minutes

Your Lab Credentials

Your instructor will provide the following details. Fill them in now — you will use them throughout the workshop.

Item Value

Cluster Name

rosa-{guid}

OpenShift API URL

{rosa_openshift_api_url}

OpenShift Web Console

{rosa_openshift_console_url}

Admin User

{rosa_openshift_admin_user}

Admin Password

{rosa_openshift_admin_password}

AWS Region

{aws_region}

Availability Zone (GPU)

{aws_az}

Log In via the CLI

  1. Save your credentials as environment variables so you can reuse them throughout the workshop:

    export GUID={guid}
export CLUSTER_NAME=rosa-${GUID}
export ADMIN_PASSWORD={rosa_openshift_admin_password}
export AWS_AZ={aws_az}
echo "GUID=$GUID  CLUSTER=$CLUSTER_NAME"

    Save them to .bashrc so they persist across terminal sessions:

    cat >> $HOME/.bashrc << 'EOF'
export GUID={guid}
export CLUSTER_NAME=rosa-${GUID}
export ADMIN_PASSWORD={rosa_openshift_admin_password}
export AWS_AZ={aws_az}
EOF

  2. Log into the cluster with the OpenShift CLI:

    oc login {rosa_openshift_api_url} \
  --username {rosa_openshift_admin_user} \
  --password {rosa_openshift_admin_password}
    Sample Output
    Login successful.
You have access to 100 projects, the list is suppressed. You can list all with 'oc projects'.
Using project "default".

  3. Verify you are logged in and have cluster-admin rights:

    oc whoami && oc get nodes
    Sample Output
    cluster-admin
NAME                                         STATUS   ROLES                  AGE   VERSION
ip-10-0-1-20.eu-west-1.compute.internal     Ready    control-plane,master   3h    v1.29.8
ip-10-0-2-45.eu-west-1.compute.internal     Ready    worker                 3h    v1.29.8
ip-10-0-3-12.eu-west-1.compute.internal     Ready    worker                 3h    v1.29.8

    You should see two or three worker nodes. No GPU node yet — you will create it in the next module.

  4. Verify the rosa CLI is available and authenticated:

    rosa whoami
    Sample Output
    AWS Account ID:               123456789012
AWS Default Region:           eu-west-1
OCM API:                      https://api.openshift.com
OCM Account ID:               1abc2defghi3jklmno4
OCM Account Name:             Workshop User
OCM Account Username:         workshop-user@example.com
OCM Organization ID:          1ABCDEFG
OCM Organization Name:        Workshop Org

Log In to the OpenShift Web Console

  1. Get your console URL:

    oc whoami --show-console

  2. Open the URL in your browser, select the cluster-admin identity provider, and log in with your credentials.

    You should land on the Administrator overview page of the OpenShift Web Console.

  3. Familiarize yourself with the left navigation:

    • Home → Overview — cluster health and capacity

    • Compute → Nodes — your current worker nodes

    • Operators → Installed Operators — where installed operators appear (currently empty)

Summary

You now have:

  • CLI access to your ROSA cluster (oc, rosa)

  • Admin access to the OpenShift Web Console

  • A clear picture of what you are building
