2. A project to host development-stage containers and processes, named "dev":

oc new-project dev --display-name="Tasks - Dev"

3. A project to host publicly-accessible application produced by the CI/CD pipeline, named "stage":

oc new-project stage --display-name="Tasks - Stage"

oc new-project cicd-dev --display-name="Dev project (openshift-tasks) to showcase CI/CD pipeline with Jenkins"
oc new-project cicd-stage --display-name="Stage project (openshift-tasks) to showcase CI/CD pipeline with Jenkins"

The Jenkins container must be able to access the OpenShift API:

oc policy add-role-to-user edit system:service account:cicd:default -n cicd
oc policy add-role-to-user edit system:service account:cicd:default -n cicd-dev
oc policy add-role-to-user edit system:service account:cicd:default -n cicd-stage

oc project cicd

Instantiate components. Use templates. 'cicd-github-template.yaml'.

oc process -f https://raw.githubusercontent.com/OpenShiftDemos/openshift-cd-demo/master/cicd-github-template.yaml | oc create -f -
