Slides for in-house study meeting. Aug 30, 2019

1. Introduction of Cloud Native CI/CD
on Kubernetes

2. Trail Map
https://github.com/cncf/trailmap

3. CI/CD
From the trail map:
Setup Continuous Integration/Continuous Delivery
(CI/CD) so that changes to your source code
automatically result in a new container being
built, tested, and deployed to staging and
eventually, perhaps, to production

5. Landscape

6. CI/CD on Kubernetes

7. Pipeline-based CI tool
Configuration as Code
Fancy Visualization
Management using CLI tool
Concourse CI
https://concourse-ci.org/

8. Get Started
https://github.com/helm/charts/tree/master/stable/concourse
TL;DR;
$ helm install stable/concourse
Need to set externalUrl to access from outside
Install the fly CLI tool for concourse management
$ fly -h

9. Pipeline

11. Declarative, GitOps CD tool
Automated deployment of desired
application states
Support for config management tools
(Kustomize, Helm etc)
Argo CD
https://argoproj.github.io/argo-cd/

12. Get Started
Quick start
$ kubectl create namespace argocd
$ kubectl apply -n argocd -f
https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
Access the endpoint by browser & Login
Get admin password
$ kubectl get pods -n argocd -l app.kubernetes.io/name=argocd-server
-o name | cut -d'/' -f 2
