Introduction of Cloud Native CI/CD on Kubernetes

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

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

CI/CD on Kubernetes

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

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

Pipeline https://github.com/starkandwayne/concourse-tutorial/blob/master/tutorials/basic/job- inputs/pipeline.yml resources: - name: resource-tutorial type: git source: uri: https://github.com/starkandwayne/concourse-tutorial.git branch: develop - name: resource-app type: git source: uri: https://github.com/cloudfoundry-community/simple-go-web-app.git jobs: - name: job-test-app public: true plan: - get: resource-tutorial - get: resource-app trigger: true - task: web-app-tests file: resource-tutorial/tutorials/basic/job-inputs/task_run_tests.yml

Pipeline

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/

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

Application
