Reference application pipeline using Azure Pipelines to build a JBoss application using Source-to-Image

Azure Pipelines JBoss S2I Example

This is a reference application pipeline using Azure Pipelines to build a JBoss application using Source-to-Image (S2I).

This Repository

This repository uses the helloworld example from jboss-eap-quickstarts GitHub repository which is placed in the src directory: https://github.com/jboss-developer/jboss-eap-quickstarts/tree/7.4.x

The Dockerfile uses instructions from Red Hat Software Collections 3, Building Application Images from Dockerfiles Using S2I Scripts

Staging the Builder Image in ACR

Push Red Hat image to Azure Container Registry. More documentation on using ACR. For this example, we'll use <acr-registry-name>.azurecr.io which you can replace with your own.

$ az login
$ az acr login --name <acr-registry-name>.azurecr.io
You can perform manual login using the provided access token below, for example: 'docker login loginServer -u 00000000-0000-0000-0000-000000000000 -p accessToken'
...
The resulting output will provide an access token
...
$ podman login <acr-registry-name>.azurecr.io -u 00000000-0000-0000-0000-000000000000 -p accessToken

We will use the JBoss Web Server builder image

$ podman login registry.redhat.io
$ podman pull registry.redhat.io/jboss-webserver-5/jws57-openjdk17-openshift-rhel8:latest
$ podman tag registry.redhat.io/jboss-webserver-5/jws57-openjdk17-openshift-rhel8 <acr-registry-name>.azurecr.io/jboss-webserver-5/jws57-openjdk17-openshift-rhel8
$ podman push <acr-registry-name>.azurecr.io/jboss-webserver-5/jws57-openjdk17-openshift-rhel8 --remove-signatures

Building the Image

Import this Git repository into Azure Pipelines, and the trigger will automatically begin to build the image. Note that this pipeline uses an agent pool named Default.

Deploying the Image

We'll create an OpenShift secret for ACR, a standalone pod (not best practices), and link the secret to the default serviceaccount. We'll then rsh into the pod and confirm that it's printing Hello World!

$ oc new-project helloworld
$ oc create secret docker-registry acr --docker-username 00000000-0000-0000-0000-000000000000 --docker-server <acr-registry-name>.azurecr.io --docker-password <password>
$ oc secrets link default acr --for=pull
$ oc run helloworld --image=<acr-registry-name>.azurecr.io/my-dev/helloworld-java:<tag>
$ oc rsh helloworld 
sh-4.4$ curl localhost:8080
Hello World!
