Before you start with the actual Cloud Native Starter project on OpenShift you must go through all of these 3 documents:
- Get access to an OpenShift cluster
- Installing Istio aka Service Mesh on your OpenShift cluster
- Requirements for Cloud Native Starter on OpenShift
To following commands deploy the base project.
Note: If you get an error "The token provided is invalid or expired" then the value for APITOKEN in file local.env is no longer valid. This typically happens when you use CRC and restart it. Follow the instructions to obtain the API token in Requirements for Cloud Native Starter on OpenShift in section "Access OpenShift via CLI".
$ os4-scripts/check-prerequisites.sh
$ os4-scripts/deploy-articles-java-jee.sh
$ os4-scripts/deploy-authors-nodejs.sh
$ os4-scripts/deploy-web-api-java-jee.sh
$ os4-scripts/deploy-web-app-vuejs.sh
$ os4-scripts/deploy-istio-ingress-v1.sh
$ os4-scripts/show-urls.sh
Run these scripts to deploy version 2 of the web-api and then apply Istio traffic routing to send 80% of the traffic to version 1, 20% to version 2:
$ os4-scripts/deploy-web-api-java-jee-v2.sh
$ os4-scripts/deploy-istio-ingress-v1-v2.sh
Create some load and view the traffic distribution in the Kiali console (Kiali URL is displayed by show-urls.sh script).
Cloud Native Starter:
$ oc delete project cloud-native-starter
