# Kubernetes plugin for drone.io

This plugin allows to update a Kubernetes deployment.

## Usage  

This pipeline will update the `my-deployment` deployment with the image tagged `DRONE_COMMIT_SHA:8`

    pipeline:
        deploy:
            image: quay.io/honestbee/drone-kubernetes
            deployment: my-deployment
            repo: myorg/myrepo
            container: my-container
            tag: ${DRONE_COMMIT_SHA:8}

Deploying several new containers, eg in a scheduler-worker setup.
    
    pipeline:
        deploy:
            image: quay.io/honestbee/drone-kubernetes
            deployment: [server-deploy, worker-deploy]
            repo: myorg/myrepo
            container: my-container
            tag: ${DRONE_COMMIT_SHA:8}

This more complex example demonstrates how to deploy to several environments based on the branch, in a `app` namespace 

    pipeline:
        deploy-staging:
            image: quay.io/honestbee/drone-kubernetes
            kubernetes_server: ${KUBERNETES_SERVER_STAGING}
            kubernetes_token: ${KUBERNETES_TOKEN_STAGING}
            deployment: my-deployment
            repo: myorg/myrepo
            container: my-container
            namespace: app
            tag: ${DRONE_COMMIT_SHA:8}
            when:
                branch: [ staging ]

        deploy-prod:
            image: quay.io/honestbee/drone-kubernetes
            kubernetes_server: ${KUBERNETES_SERVER_PROD}
            kubernetes_token: ${KUBERNETES_TOKEN_PROD}
            deployment: my-deployment
            repo: myorg/myrepo
            container: my-container
            namespace: app
            tag: ${DRONE_COMMIT_SHA:8}
            when:
                branch: [ master ]
