Drone Kubernetes

Drone plugin to create/update Kubernetes resources.

It uses the latest k8s go api, so it is intened to use on Kubernetes 1.9+. I can't guarantee it will work for previous versions.

You can directly pull the image from sh4d1/drone-kubernetes

Supported resources

Currently, this plugin supports:

• apps/v1
  • DaemonSet
  • Deployment
  • ReplicaSet
  • StatefulSet
• apps/v1beta1
  • Deployment

  • PersistentVolume
  • PersistentVolumeClaim
  • Pod
  • ReplicationController
  • Service
• extensions/v1beta1
  • DaemonSet

Inspiration

It is inspired by vallard and his plugin drone-kube.

Usage

Here is how you can use this plugin:

pipeline:
  deploy:
    image: sh4d1/drone-kubernetes
    kubernetes_template: deployment.yml
    kubernetes_namespace: default
    secrets: [kubernetes_server, kubernetes_cert, kubernetes_token]

Secrets

You need to define these secrets before.

$ drone secret add --image=sh4d1/drone-kubernetes -repository <your-repo> -name KUBERNETES_SERVER -value <your API server>

$ drone secret add --image=sh4d1/drone-kubernetes -repository <your repo> -name KUBERNETES_CERT -value <your base64 encoded cert>

$ drone secret add --image=sh4d1/drone-kubernetes -repository <your repo> -name KUBERNETES_TOKEN -value <your token>

How to get values of KUBERNETES_CERT and KUBERNETES_TOKEN

List secrets of default namespace

$ kubectl get -n <namespace of secret> default secret

Show the ca.crt and token from secret

$ kubectl get secret -n <namespace of secret> <name of your drone secret> -o yaml | egrep 'ca.crt:|token:'

You can copy/paste the encoded certificate to the KUBERNETES_CERT value. For the KUBERNETES_TOKEN, you need to decode it:

• echo "<encoded token>" | base64 -d
• kubectl describe secret -n <your namespace> <drone secret name> | grep 'token:'
