Acme Air Sample Application for Multi-architecture Compute

This application shows an implementation of a fictitious airline called "Acme Air" to exercise OpenLiberty JEE Profile with MongoDB as a datastore. This repository is used to highlight various Multi-architecture compute scenarios.

The application is forked from https://github.com/blueperf/acmeair-multiarchitecture-compute

The application depends on:

mongodb     | 4.4.18 | podman pull icr.io/ppc64le-oss/mongodb-ppc64le:4.4.18
openliberty | latest | podman pull icr.io/appcafe/open-liberty:kernel-slim-java11-openj9-ubi
ubi-minimal | latest | podman pull registry.access.redhat.com/ubi8/ubi-minimal

Build

Use maven to build the project

• git clone https://github.com/ocp-power-demos/acmeair-multiarchitecture-compute
• cd acmeair-multiarchitecture-compute
• cd source && mvn clean package && cd ..

Note, if you are on a mac, you can setup maven using brew install maven and dnf install -y maven.noarch java-11-openjdk.x86_64 Note, the tests are commented out as they depend on out-of-date MongoDb test dependencies.

Setup

1. Clone this repository

❯ git clone https://github.com/ocp-power-demos/acmeair-multiarchitecture-compute.git

2. Create the MONGODB user and encode to base64.

❯ export MONGODB_USER=admin

3. Create the MONGODB password and encode to base64. (an example of admin)

❯ export MONGODDB_PASS=admin

4. Make a secret file that is going to get loaded.

❯ cat << EOF > ./manifests/base/env.secret
username=${MONGODB_USER}
password=${MONGODB_PASS}
EOF

5. Download kustomize from https://github.com/kubernetes-sigs/kustomize/releases/latest

❯ curl -o kustomize.tar.gz -L https://github.com/kubernetes-sigs/kustomize/releases/download/kustomize%2Fv5.1.0/kustomize_v5.1.0_darwin_amd64.tar.gz
❯ tar xvf kustomize_v5.1.0_darwin_amd64.tar.gz

6. Run the kustomize for single-arch (Intel only) and does not use node-selectors. This use-case is single architecture Intel only without nodeSelectors. It will fail when scheduled on a Power node.

❯ kustomize build manifests/overlays/single-arch-intel | oc apply -f -
project.project.openshift.io/acmeair created
service/acmeair-http created
service/acmeair-https created
route.route.openshift.io/acmeair created
horizontalpodautoscaler.autoscaling/acmeair-java-autoscaler created
service/acmeair-db created
secret/mongodb-config created
secret/mongodb-creds created
deployment.apps/acmeair-multiarchitecture-compute-deployment created
deployment.apps/acmeair-db created

7. Run the kustomize for single-arch (PowerPC only). This use-case is single architecture Power only with nodeSelectors so that it will not run on Intel.

❯ ./kustomize build manifests/overlays/single-arch-power | oc apply -f -

8. Run the kustomize for multi-arch (non-OpenStack)

❯ kustomize build manifests/overlays/multi-arch | oc apply -f -

9. Run the kustomize for multi-arch (OpenStack)

❯ kustomize build manifests/overlays/multi-arch-openstack | oc apply -f -

10. Run the kustomize for multi-arch (PowerVS) using EmptyDir

❯ kustomize build manifests/overlays/multi-arch-powervs-empty | oc apply -f -

11. Run the kustomize for ibmcloud using nfs

❯ kustomize build manifests/overlays/ibmcloud | oc apply -f -

This one uses an empty dir, when the Pod is destroyed the local data is destroyed.

Note, you may need to run oc apply -f manifests/overlays/multi-arch-openstack/storageclass.yaml.

If the app does not work, make sure you setup the .env.secret file.

Database Load

1. Find the Route to the AcmeAir Route

❯ export ACMEAIR_ROUTE=$(oc get route acmeair -ojsonpath='{.status.ingress[0].host}' -n acmeair)

2. Find the Path to the Loader and open the URL. You must use https://

❯ echo "https://${ACMEAIR_ROUTE}/loader.html"
https://acmeair.local.ocp-multiarch.xyz/loader.html

3. Click Load the database

4. Confirm the Successful Load. You should see no HTTP error codes.

Note, you'll need to Accept any Certificate Warning.

Use

1. Navigate to index.html

2. Click Login

3. Enter [email protected] and Click OK

4. Try Booking and Canceling a Flight
