Demos

microservices-demo (Online Boutique)
rhods-demo (Red Hat OpenShift Data Science)

All of the demos have been tested on new ROSA and ARO clusters. If you need a new ROSA or ARO cluster, you can use the instructions below.

Create a new ROSA Cluster

# PREREQUISITES: Verify your AWS CLI and ROSA CLI are authenticated, and AWS account roles exist
# -------------- All of the calls below must return succesfully in order to proceed
aws sts get-caller-identity
rosa whoami
rosa create user-role --mode auto --yes
rosa create account-roles --mode auto --yes

# REQUIRED HUMAN INPUT: Provide a unique name for your cluster
export CLUSTER_NAME=

# Create a cluster (accept all defaults)
rosa create cluster \
  --cluster-name $CLUSTER_NAME \
  --sts \
  --region us-west-2 \
  --availability-zones us-west-2a
  --version 4.13.3 \
  --replicas 2 \
  --compute-machine-type c6a.xlarge \
  --machine-cidr 10.0.0.0/16 \
  --service-cidr 172.30.0.0/16 \
  --pod-cidr 10.128.0.0/14 \
  --host-prefix 23 \
  --mode auto \
  --yes

# You may have to create roles and OIDC provider
rosa create operator-roles --cluster $CLUSTER_NAME --mode auto --yes
rosa create oidc-provider --cluster $CLUSTER_NAME --mode auto --yes

# Wait for the cluster to become ready (ctrl-c to cancel watch)
rosa logs install -c $CLUSTER_NAME --watch

# Create your cluster-admin user and 
# follow the instructions in the response to login to the cluster using the oc command
rosa create admin --cluster $CLUSTER_NAME
oc login https://... --username cluster-admin --password 12345-...

# Remove the self-provisioner role from all authenticated users to revoke default behaviour of project creation from authenticated users
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth

# Retrieve the OpenShift Web Console address and log in with your cluster-admin account
oc whoami --show-console

At this point, you should have:

• access to your ROSA cluster via command line
• access to your ROSA cluster via Web Console
• visibility of your ROSA cluster in the Red Hat OpenShift Console

Create a new ARO Cluster

Demos

microservices-demo (Online Boutique)

The Online Boutique is a cloud-first microservices demo application. Online Boutique consists of an 11-tier microservices application. The application is a web-based e-commerce app where users can browse items, add them to the cart, and purchase them. Source

cd microservices-demo
oc new-project microservices-demo
oc adm policy add-scc-to-user anyuid -n microservices-demo -z default
oc apply -f ./release/kubernetes-manifests.yaml

rhods-demo (Red Hat OpenShift Data Science)

Install RHODS operator and follow along a scenario that aims to solve the challenges for a theoretical data science organization:

# REQUIRED HUMAN INPUT: Provide a common password for our 12 users, keep it simple which will help with demo pacing

echo $(htpasswd -B -n -b alvin $HTPASSWD_PASS) | tee -a htpasswd-rhods > /dev/null

echo $(htpasswd -B -n -b penny $HTPASSWD_PASS) | tee -a htpasswd-rhods > /dev/null
