CI/CD Setup
Steps I follow to setup a CI CD workflow. Write Dockerfile in the code repo. Write a k8s Manifest file using kustomize template. Following this tree structure. ├── base │ └── app │ ├── deployment.yaml │ ├── kustomization.yaml │ └── service.yaml └── overlay ├── production │ └── kustomization.yaml └── staging └── kustomization.yaml Write a skaffold file ( skaffold init will auto initialize itself ). Build Docker image and Render the k8s manifest using skaffold. skaffold build && \ skaffold render --digest-source='tag' -p staging -o ../path-to/manifest.yml Manually push the rendered k8s to the manifest repository. Setup the k8s to access the private repository kubectl create secret generic <secret-name> \ --from-file=.dockerconfigjson=~/.docker/config.json \ --type=kubernetes.io/dockerconfigjson Update the K8s manifest with spec: template: spec: imagePullSecrets: - name: <secret-name> Setup argo cd in the target k8s cluster. ArgoCD Getting Started kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}' kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d; echo Login and Link repository to argocd. Create an app in argocd and configure to access the repository and the cluster to deploy.
