Welcome, stranger!

You arrived at a Kubernetes cluster repository.

It contains a list of cluster resources managed by Flux CD GitOps tool.

To add a new resource to the cluster, feel free to submit a PR for master branch.

Resources can be defined as:

• Raw YAML manifests:

    apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
      labels:
        app: nginx
      name: nginx
      namespace: monitoring
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: nginx
      template:
        metadata:
          labels:
            app: nginx
        spec:
          containers:
          - image: nginx
            name: nginx
  

• HelmRelease CRD manifest for self-hosted charts:

    apiVersion: helm.fluxcd.io/v1
    kind: HelmRelease
    metadata:
      name: default-namespace-policies
      namespace: flux   # We put HelmRelease resources to the same namespace as Flux
    spec:
      releaseName: default-namespace-policies
      targetNamespace: monitoring   # The namespace where Helm chart gets deployed
      chart:
        git: https://github.com/artazar/helm     # Git repository URL where Helm chart is stored
        path: security/default-namespace-policies   # The path to the chart on the repository
        ref: master                                 # Use custom branch if needed
        secretRef:
          name: flux-git-auth   # This should be added for the Helm charts on our internal Git repositories to fetch credentials
      values:                   # The list of Helm values goes here
        allow_internet: true
  

• HelmRelease CRD manifest for public charts:

    apiVersion: helm.fluxcd.io/v1
    kind: HelmRelease
    metadata:
      name: nginx
      namespace: flux   # We put HelmRelease resources to the same namespace as Flux
    spec:
      releaseName: nginx
      targetNamespace: flux-test   # The namespace where Helm chart gets deployed
      chart:
        repository: https://charts.bitnami.com/bitnami
        name: nginx
        version: 7.1.2
      values:
        fullnameOverride: nginx
        replicaCount: 2
        image:
          tag: 1.19.3
  

• Kustomization files

Put your resources inside directories, named after namespaces, avoid creating new files on the repository root.

The resources should appear in the cluster (or disappear if getting removed) within 10 minutes after merging to master.

In case this does not happen, check Flux logs for any errors:

# kubectl -n flux logs deploy/flux
# kubectl -n flux logs deploy/helm-operator

Pre-commit

This repository uses Pre-commit hooks.

To use them locally, run the following commands:

# pip install pre-commit
# pre-commit install
