(experimental) Luet Kubernetes CRD controller

Simple CRD that uses luet and img to build packages on Kubernetes. It doesn't require privileged permissions, and builds the image as user 1000 in the workload pod.

If you need to build docker images only, have a look at img-controller

Install

To install it in your k8s cluster:

$ kubectl apply -f https://raw.githubusercontent.com/mudler/luet-k8s/master/hack/kube.yaml

Build packages

The controller expose a new PackageBuild Kubernetes resource type, which can be used to build docker images with img and packages with luet.

To build a package, for example:


$ cat <<EOF | kubectl apply -f -
apiVersion: luet.k8s.io/v1alpha1
kind: PackageBuild
metadata:
  name: test
spec:
  packageName: container/img
  repository: 
    url: "https://github.com/mocaccinoOS/mocaccino-extra"
  options:
    pull: true
    imageRepository: "quay.io/mocaccinocache/extra-amd64-cache"
EOF

    # Annotations to apply to workload pod

  registry:
    enabled: true
    username: "user"
    password: "pass"
    registry: "quay.io"
    fromSecret: "secret-key" # Only if using credentials from secret
  storage:
    enabled: true
    url: "minio_url"
    secretKey: "minio_secret_key"
    accessID: "minio_access_id"
    bucket: "bucket"
    path: "/bucket/path"
    fromSecret: "secret-Key" # Only if using credentials from secrets
  repository: 
    url: "https://github.com/mocaccinoOS/mocaccino-extra"
    path: "/foo/path"
    checkout: "hash_or_branch"
  options:
    pull: true
    clean: true
    onlyTarget: true
    full: true
    all: true
    privileged: true
    compression: "gzip"
    resources:
        requests:
            cpu: "100m"
            memory: "200Mi"
        limits:
            cpu: "10m"
            memory: "1Mi"
    push: true
    tree:
    - /tree/path
    noDeps: true
    color: true
    spinner: true
    imageRepository: "quay.io/mocaccinocache/extra-amd64-cache"

If storage and registry credentials are sourced from secrets, the secret should have the following fields and live in the same namespace of the workload:

storageUrl: ""
storageSecretKey: ""
storageAccessID: ""
registryUri: ""
registryPassword: ""
registryUsername: ""

Uninstall

First delete all the workload from the cluster, by deleting all the packagebuild resources.

Then run:


$ kubectl delete -f https://raw.githubusercontent.com/mudler/luet-k8s/master/hack/kube.yaml
