Creating your own pipeline

Video 1: Creating your own pipeline

The build configuration used for creating the pipeline is https://github.com/VeerMuchandi/pipeline-example/blob/master/pipeline.yml

Video 2: Edit the pipeline to deploy across projects

The initial Jenkinsfile is https://github.com/VeerMuchandi/pipeline-example/blob/master/Jenkinsfile1.txt

The edited Jenkinsfile is https://github.com/VeerMuchandi/pipeline-example/blob/master/Jenkinsfile2.txt

In this example, the pipeline runs in the CICD Project. We will build and deploy an application first in a project named 'Development'. Later we will push the image created into a project named 'Testing'.

Here are the commands I used from the OpenShift CLI:

Creating a development Project and to provide edit access to the jenkins service account in the development project.

oc new-project development

oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n development

Creating a testing Project . Provide edit access to the jenkins service account in the testing project. Then provide image-puller access, so that testing project can pull an image from the development project.

oc new-project testing

oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n testing

oc policy add-role-to-group system:image-puller system:serviceaccounts:testing -n development

To create a deployment configuration in the testing project that points to the image from development project, create a service and route:

oc create deploymentconfig myapp --image=<<RegistryServiceIP>>:5000/development/myapp:promoteToQA

oc expose dc myapp --port=8080

oc expose svc myapp
