This repo is a sample Tekton pipeline that builds and deploys the Spring PetClinic sample Spring Boot application on OpenShift. This demo creates:

• 3 namespaces for CI/CD, DEV and STAGE projects
• A sample Tekton pipeline
• Gogs git server (username/password: gogs/gogs)
• Sonatype Nexus (username/password: admin/admin123)
• SonarQube (username/password: admin/admin)
• Report repository for test and project generated reports
• Imports Spring PetClinic repository into Gogs git server
• Adds a webhook to spring-petclinic repository in Gogs to start the Tekton pipeline

On every push to the spring-petclinic git repository on Gogs git server, the following steps are executed within the pipeline:

1. Code is cloned from Gogs and the unit-tests are run
2. Application is packaged as a JAR and pushed to Sonatype Nexus snapshot repository
3. In parallel, the code is analyzed by SonarQube for anti-patterns, code coverage and potential bugs
4. A container image (spring-petclinic:latest) is built using the Source-to-Image for Java apps, and pushed to OpenShift internal registry
5. Application image is deployed with a rolling update

1. Get an OpenShift cluster via https://try.openshift.com

2. Install OpenShift Pipelines Operator

3. Download OpenShift CLI and Tekton CLI

4. Deploy the demo

   $ oc new-project demo
   $ git clone https://github.com/siamaksade/tekton-cd-demo 
   $ demo.sh install
   

5. Start the deploy pipeline by making a change in the spring-petclinic Git repository on Gogs, or run the following:

   $ demo.sh start
   

6. Check pipeline run logs

   $ tkn pipeline logs petclinic-deploy-dev -f NAMESPACE
