CI/CD Demo - Minishift

Provision minishift and setup required CI components (Gogs, Jenkins, SonarQube). Deploy a demo app to showcase a CI/CD pipeline.

Requirements

• minishift 1.5+
• Make sure minishift is available in your PATH

Build

All-in bootstrap

• bootstrap

./minishift-start && \
./minishift-warmup && \
./minishift-create-projects && \
./minishift-admin-setup && \
./minishift-deploy-demo && \
./minishift-start-pipeline

Manual step by step

• Start with clean installation

minishift delete --clear-cache

• minishift-start

minishift start --memory=10240 --vm-driver=virtualbox && \
minishift oc-env

This will prompt the web console URL and logging details

• minishift-warmup

oc login -u developer
minishift ssh docker pull openshiftdemos/gogs:0.11.29
minishift ssh docker pull openshiftdemos/sonarqube:6.7
minishift ssh docker pull sonatype/nexus3:3.6.1
minishift ssh docker pull registry.access.redhat.com/openshift3/jenkins-2-rhel7
minishift ssh docker pull registry.access.redhat.com/openshift3/jenkins-slave-maven-rhel7 
minishift ssh docker pull registry.access.redhat.com/jboss-eap-7/eap70-openshift

This operation will take some time as it will download some docker images!!!

• minishift-create-projects

eval $(minishift oc-env)
oc login -u developer
# Create Projects
echo "Creating DEV namespace ..."
oc new-project dev --display-name="Dev Environment" && \
echo "Creating STAGE namespace ..."
oc new-project stage --display-name="Stage Environment" && \
echo "Creating CI/CD namespace ..."
oc new-project cicd --display-name="CI/CD"

# Grant Jenkins Access to Projects
echo "Adding roles to admin user ..."
oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n dev
oc policy add-role-to-user edit system:serviceaccount:cicd:jenkins -n stage

• minishift-admin-setup

eval $(minishift oc-env)
oc login -u system:admin
# Make sure latest Jenkins image is installed
oc import-image jenkins:v3.7 --from="registry.access.redhat.com/openshift3/jenkins-2-rhel7" --confirm -n openshift
oc tag jenkins:v3.7 jenkins:latest -n openshift

# Manage policy on the cluster
oc adm policy add-role-to-user admin system -n dev 
oc adm policy add-role-to-user admin system -n stage 
oc adm policy add-role-to-user admin system -n cicd
 
# Update the annotations on namespace resources    
oc annotate --overwrite namespace dev demo=openshift-cd 
oc annotate --overwrite namespace stage demo=openshift-cd
oc annotate --overwrite namespace cicd  demo=openshift-cd

oc create -f https://raw.githubusercontent.com/jboss-openshift/application-templates/master/jboss-image-streams.json -n openshift

• minishift-deploy-demo

eval $(minishift oc-env)
oc login -u developer
# Download ci-cd template and create app from it
oc new-app -n cicd -f https://raw.githubusercontent.com/OpenShiftDemos/openshift-cd-demo/ocp-3.7/cicd-template.yaml

• minishift-start-pipeline

eval $(minishift oc-env)
oc start-build tasks-pipeline

This operation will take some time as it will have to download all artifacts from nexus and promote the demo app across all the pipeline stages.
