Kubernetes Deployments

by mactynow

The example Yaml configurations in this file are using the legacy 0.8 syntax. If you are using Drone 1.0 or Drone Cloud please ensure you use the appropriate 1.0 syntax. Learn more here.

The Kubernetes plugin can be used to upgrade a Kubernetes deployment with a newer version of an image. This is equivalent to running the following kubectl command:

kubectl set image deployment/nginx-deployment nginx=nginx:1.9.1

Example pipeline configuration:

pipeline:
  deploy:
    image: quay.io/honestbee/drone-kubernetes
    kubernetes_server: https://kubernetes.company.org
    kubernetes_token: CXHVLJSDKJFS...
    namespace: app
    deployment: my-deployment
    repo: myorg/myrepo
    container: my-container
    tag: mytag

Deploying containers across several deployments, eg in a scheduler-worker setup. Make sure your container name in your manifest is the same for each pod.

pipeline:
  deploy:
    image: quay.io/honestbee/drone-kubernetes
-   deployment: my-deployment
+   deployment: [ server-deploy, worker-deploy ]
    repo: myorg/myrepo
    container: my-container
    tag: mytag

Deploying multiple containers within the same deployment.

pipeline:
  deploy:
    image: quay.io/honestbee/drone-kubernetes
    deployment: my-deployment
    repo: myorg/myrepo
-   container: my-container
+   container: [ my-container-1, my-container-2 ]
    tag: mytag
