with OpenShift CI/CD Components ( Nexus, SonarQube, Jenkins) Deploy Jenkins on OpenShift Customize Jenkins Building a Jenkins Pipeline Demo Overview Going through the Demo Resources
apps to customers by introducing automation into the stages of app development. The main concepts attributed to CI/CD are continuous integration, continuous delivery, and continuous deployment. CI/CD is a solution to the problems integrating new code can cause for development and operations teams
is an automation process targeting developers to improve the quality of their code and the reliability of their applications. Each Git is verified by an automated build, allowing teams to detect problems early. The goal of Continuous Delivery (CD), is to have code in a state that is always ready for deployment to a production environment. Continuous Release The goal of Continuous Release (CR), also called "Continuous Deployment" (not to be confused with Continuous Delivery), is to push all of your changes to your end users as quickly and efficiently as possible.

Helm, Docker, P2, OBR, APT, GO, R, Conan components and more. - Manage components from dev through delivery: binaries, containers, assemblies, and finished goods. - Set up one instance in OpenShift Container Platform cluster to cache build artifacts close to builds - Can act as a container registry
performs operations on OCI or Docker images ▸ Skopeo performs the following operations: ･ Copy one image from one registry to another ･ Inspect a remote image ･ Delete an image from an image repository ▸ Supported image and repository types: ･ Containers-storage ･ Dir ･ Docker ･ Docker-archive ･ Oci
not require a damon to be running - Can perform operations on images without pulling the image Skopeo - Docker daemon needs to be started and run with privileges. - It is heavy on resource consumption - Soft skills development $ skopeo copy docker://source.registry/myimage:latest \ docker://destination.registry/myimage:v1.O $ docker pull source.registry/myimage:latest $ docker tag source.registry/myimage:latest destination.registry/myimage:v1.O $ docker push destination.registry/myimage:v1.O
Plugin This plug-in is installed and enabled by default when using the inbuilt OpenShift Container Platform Jenkins image. The plug-in enables OpenShift Container Platform specific functions to use within the Jenkinsfile for your pipeline. The OpenShift Jenkins Sync Plugin acts as a bridge between the OpenShift cluster and the Jenkins instance, and keeps build configuration and build objects in sync with Jenkins jobs and builds. OpenShift Login Plugin The OpenShift Login Plugin integrates the authentication and authorization of your Jenkins instance with your OpenShift cluster, providing a single sign-on functionality. Red Hat OpenShift Container Platform includes Jenkins 2 Image based on Red Hat Enterprise Linux and Preconfigured with supported plug-in versions
\ > edit system:serviceaccount:jenkins-project:jenkins \ > -n project-dev The service account associated with the Jenkins deployment must have the edit role for each project where Jenkins performs some operation. $ oc policy add-role-to-user \ > edit system:serviceaccount:jenkins-project:jenkins \ > -n project-stage
pipeline language - Declarative pipeline becoming more popular - Can embed Groovy script steps where necessary - OpenShift actions have to be embedded as script - Agents specify builder: any, maven, nodejs, or custom - Pipelines are divided into stages - Stages have graphical representation in Jenkins OpenShift UI
cloned from Gogs (self-hosted Git - minimal footprint) ▸ WARs are in Nexus (repository for artifacts like jars and wars) ▸ SonarQube for Code Quality ▸ Jenkins for CICD Pipeline management ▸ Deployed on WildFly (lightweight JBoss) ▸ quay.io image registry for containers
▸ Clone and checkout the eap-7 branch of the OpenShift-tasks git repository and using an IDE (e.g. JBoss Developer Studio), remove the @Ignore annotation from src/test/java/org/jboss/as/quickstarts/tasksrs/service/UserResourceTest.java test methods to enable the unit tests. Commit and push to the git repo. ▸ Check out Jenkins, a pipeline instance is created and is being executed. The pipeline will fail during unit tests due to the enabled unit test. ▸ Check out the failed unit and test src/test/java/org/jboss/as/quickstarts/tasksrs/service/UserResourceTest.java and run it in the IDE. ▸ Fix the test by modifying src/main/java/org/jboss/as/quickstarts/tasksrs/service/UserResource.java and uncommenting the sort function in getUsers method. ▸ Run the unit test in the IDE. The unit test runs green. ▸ Commit and push the fix to the git repository and verify a pipeline instance is created in Jenkins and executes successfully.
