CI/CD demo with Openshift and its addons

Openshift CI/CD Demo

This repo contains all files needed to execute Caio's CI/CD demo over Openshift 4.x.

Environment simulated in this demo:

• Develop: place where all developers integrate their changes.
• Staging: futher similar with production where automated and manual quality gates can be performed.
• Production: customers use services available here.

Branching strategy:

Prerequisites

• 1x Openshift Container Platform version 4.5 or later.
• Helm CLI installed in your workstation.
• OC CLI installed in your workstation.
• Make your own fork of the following repositories:
  • Yaml Online.
  • MS Yaml Online.
  • WS Yaml Online.

Step by step

Prepare

1. Clone this repo:

   git clone https://github.com/caiomedeirospinto/ocp-cicd-demo.git

2. Login to Openshift with an Cluster admin account.

3. Create projects:

   helm template charts/bootstrap-project/ | oc apply -f -

Do it with GitOps

INFO!

To execute this step by step, you gonna need ArgoCD CLI installed.

1. Install Openshift GitOps:

   oc apply -f operators/gitops/operator/

   Wait a minute and execute:

   oc apply -f operators/gitops/service/

2. Wait for Openshift GitOps to be ready:

   oc get pods -n openshift-gitops

   Ver output esperado.

3. Deploy base platforms:

   helm template -f charts/ubiquitous-journey/base.yaml charts/ubiquitous-journey/ | oc apply -n openshift-gitops -f -

   INFO!

   Some code are based on Ubiquitous Project, so if you wanna find more amazing tools as a code check it out!

4. Wait for ArgoCD apps get ready:

   argocd login "$(oc get route openshift-gitops-server -n openshift-gitops -o go-template='{{ .spec.host }}')" --username admin \
       --password "$(oc get secrets openshift-gitops-cluster -n openshift-gitops -o go-template='{{index .data "admin.password"}}' | base64 --decode)"
   argocd app list

   Ver output esperado.

5. Deploy YAML Online platform:

   helm template -f charts/ubiquitous-journey/apps.yaml charts/ubiquitous-journey/ | oc apply -n openshift-gitops -f -

6. Execute pipeline that will release Helm Charts needed to Nexus:

   oc apply -n nexus -f .iac/templates/first-run.yaml

   You can check it on the Openshift Web Console, Developer view and menu option Pipelines.

7. Replace your Nexus URI in the .iac/Chart.yaml files of your fork repositories:

   oc get route nexus -n nexus -o go-template='{{ .spec.host }}'

8. Simulates a push event to develop Git webhook calling to event listener:

   curl "$(oc get route )"

. Login to Openshift Web Console, go to Developer view and to the project dev:

. Wait for

Do it without GitOps
