devops-showcase's Introduction
CONTEXT I made this to quickly showcase how a devops setup and workflow might look like in an enterprise environment. (definitely not as a homework for any interviewing process) This utilizes EKS on AWS cloud which is controlled by terraform code. Service deployment is automated. Github Actions CICD handles build process while ArgoCD provides a nice devops dashboard and triggers deployment when change is detected (GitOps concept). Requirements 1. kubectl 2. terraform 3. aws (CLI) How to Deploy 1. Create EKS cluster using terraform - cd terraform - terraform init - terraform validate - terraform apply Here terraform will error in the last step due to argocd.tf cannot be deployed because kubectl has not bind with the cluster yet. 2. Bind kubectl with the new cluster - aws eks update-kubeconfig --region ap-northeast-2 --name showcase-cluster 3. Apply terraform again to deploy Argocd - terraform apply 4. Port-forward Argocd on EKS cluster to local machine using kubectl - kubectl -n argocd port-forward svc/argocd-server 2222:80 5. Get argocd password in secrets and login - kubectl get secrets argocd-initial-admin-secret -o yaml -n argocd - echo "INITIAL_PASSWORD" | base64 -d Go to localhost:2222 and login (username: admin) 6. Create Argocd deployment with argoCD UI - New App - Select 'Automatic' under 'SYNC POLICY' - use this repo's url in 'Repository URL' - use 'showcase-chart' under 'Path' this will make argocd use helmcharts under that directory for deployment - under 'VALUES-FILES' input 'values-dev.yaml' to make dev env deployment - create and sync argocd application 7. Test querying the server-app using port-foward - kubectl -n dev port-forward deployment/server 1111:8080 - curl localhost:1111 ** this README doesn't include information on CICD workflows and secrets setup
