The PingPong Test Application

This is an application to see the following features in an OKD / OpenShift Cluster:

• automatic docker build from an external repo (this!)
• deployment with kustomize (runs also in ArgoCD)
• horizontal scaled applications with dynamic load distribution (try reload in your browser, ...)

This app can act as template for your own first OKD / OpenShift playground.

build

oc login -u myuser api.myfamouscluster.net:6443
oc project myproject
oc apply -k kustomize/build/
oc start-build pingpong-app --follow
oc start-build pingsaml-app --follow

run

oc apply -k ./kustomize/pingpong-template  

or use ArgoCD ;-)

use helm

Go in directory helm.

• Create helm package: helm package pingpong

• Make an index: helm repo index . --merge index.yaml

• Install (after editing helm/values.yaml):

  cd helm
  helm install myfamous-release pingpong --values values.yaml
  

SAML example config

For the second SAML example (pingsaml) you have to config your variables in ./kustomize/pingsaml-template:

• import keycloak-import.json in your KeyCloak instance as starting point
• setting your variables in kustomization.yaml to the correct values
• convert the client-certificate and the realm cert from KeyCloak:
  • in KeyCloak: Clients -> https://YourClient -> Keys -> Export -> PKCS12 -> Download (you have to set to temp passwords)
  • import this PKCS#12 file and generate the 3 PEM files: clientcert.pem, clientkey.pem and idpcert.pem
  • I'm using XCA (https://hohnstaedt.de/xca/) for this, it's absolutely great!
• deploy your app with oc apply -k ./kustomize/pingsaml-template
• it should work now ;-)
