FluxCD

To bootstrap a FluxCD installation for a Git repository, you need to follow these steps:

1. Install FluxCD: Begin by installing FluxCD on your desired Kubernetes cluster. FluxCD is a GitOps operator that automatically syncs code changes from a Git repository to your cluster.
2. Create a repository: Set up a Git repository that will contain your Kubernetes manifests, known as the manifests repository. This repository will serve as a source of truth for your cluster's desired state.
3. Generate a deployment key: Generate an SSH key pair to securely authenticate your FluxCD installation with the Git repository. The public key is used to configure repository access.
4. Configure repository access: Add the generated public key as a deploy key or set up read-only access for your Git repository. This allows FluxCD to clone the repository and synchronize it with your cluster.
5. Bootstrap FluxCD: Use the FluxCD command-line interface or Kubernetes manifest files to bootstrap FluxCD. Provide the Git repository's URL, the SSH deployment key, and any other required configuration details.
6. Verify and sync: After bootstrapping, FluxCD will authenticate with the Git repository and start monitoring it for changes. It will automatically apply any modifications to your cluster's state. Verify that FluxCD is syncing correctly and monitoring the desired Git repository by checking the logs and cluster state.
7. Apply best practices: Consider implementing additional FluxCD features and best practices, such as resource automation, release management, and GitOps workflows, to enhance your deployment and maintenance processes.
