Tekton + RedHat Fuse Demo On Openshift 4.X

This simple demo builds, packages and deploys a quick Camel Route example using Tekton Pipelines. Deployed API is exposed via the 3Scale API Management gateway with OpenID integration (RedHat SSO)

Prerequisites

• Openshift 4.13.X
• Git access to the source repo
• Openshift Pipelines installed
• Openshift GitOps
• Openshift Pipelines

Getting started

Deploying on Openshift

There are a few prerequisites that need to be deployed beforehand:

1. Install and deploy ArgoCD as shown here
2. Deploy ocp-pipeline with manifests found in the previously mentioned repo:

$ oc apply -k config/ocp-pipelines/argocd

Install and run tekton pipeline manifests

1. Create a new project:

$ oc new-project fuse-jdbc-demo

2. Install tekton pipeline components:

oc apply -k tekton/

3. Run the pipeline via the Web UI (or create a pipelinerun manifest)

4. Deploy ArgoCD applications:

oc apply -k argocd/postgres
oc apply -k argocd/fuse-spring

And wait for the deployment to show

$ oc get deployment -n fuse-jdbc-demo
[...]
NAME                      READY   UP-TO-DATE   AVAILABLE   AGE
spring-fuse-demo-github   0/1     1            0           19m
[...]

You can then discover the url by typing

$ oc get ingress -n fuse-demo
[...]
NAME                      CLASS    HOSTS                        ADDRESS   PORTS   AGE
spring-fuse-demo-github   <none>   fuse.apps.kubernetes.local             80      2m29s
[...]

Sample Post Call

linux# curl -d '{"userId":7, "title":"This is a title", "body":"Blah"}' -H "Content-Type: application/json" http://fuse.apps.kubernetes.local/camel/api/post

PS> wget -Method Post -Body '{"userId":7, "title":"This is a title", "body":"Blah"}' -ContentType 'application/json' http://fuse.apps.kubernetes.local/camel/api/post

Cleaning up

If you no longer need the example, you can just run

$ oc delete -k argocd/fuse-spring
$ oc delete -k argocd/postgres

TODO

1. Fix bugs here and there
