GitOps Getting Started

This repo contains guidance on how to start utilizing GitOps best practices with a Kubernetes cluster. Define the GitOps term!

Environment

1. Existing Kubernetes cluster in cloud provider [e.g. DigitalOcean]
2. Git repository for representing a state of Kubernetes applications.

Goals

1. Allow team members to deploy applications to the staging/dev environment more easily than nothing.
2. Deploy from a branch.
3. Record a video describing the process of setting up GitOps env.

Non-goals

1. Earn money

Process

• Gain access to Kubernetes cluster by getting kubeconfig
• Configure kube config and check access to the cluster by the command kubectl get pods --all-namespaces should return something
• Install argocd
• Make ArgoCD accessible from the internet and issue an SSL certificate for it
• Add access via third-party provider
  • Github, Github groups (prod-deployers)
• Organize Github structure for ArgoCD
  • apps - ArgoCD applications
  • charts - helm charts
  • values - values for the charts for specific env
• Add kubernetes cluster into argocd (? should be added by default the one where argocd is installed).
• Connect ArgoCD to the git repository
• Make tests of deployments

Tools

1. Kubefirst - one to-go tool for fast setup of everything needed for GitOps
2. Kratix - a contract-based tool to establish a connection between application and infrastructure teams
3. Backstage - open platform for building developer portals
