Drone Kube

by vallard

This drone kubernetes plugin does the equivalent of:

kubectl apply -f deployment.yaml

The advantages of this plugin is that the deployment.yaml file can be a template file. We are able to substitute values like {{ build.number }} inside the file so you can update docker image names.

Basic example:

pipeline:
  deploy:
     image: vallard/drone-kube
     template: deployment.yaml

Example configuration with non-default namespace:

pipeline:
  kube:
    image: vallard/drone-kube
    template: deployment.yaml
+   namespace: mynamespace

You can also specify the server in the configuration as well. It could alternatively be specified as an environment variable as shown in the next section.

pipeline:
  kubernetes:
    image: vallard/drone-kube
    template: deployment.yaml
+   namespace: mynamespace
+   server: https://10.93.234.28:6433
