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:0:8

pipeline:
    deploy:
        image: quay.io/honestbee/drone-kubernetes
        deployment: my-deployment
        repo: myorg/myrepo
        container: my-container
        tag: ${DRONE_COMMIT_SHA:0:8}

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: [server-deploy, worker-deploy]
        repo: myorg/myrepo
        container: my-container
        tag: ${DRONE_COMMIT_SHA:0:8}

Deploying multiple containers within the same deployment.

pipeline:
    deploy:
        image: quay.io/honestbee/drone-kubernetes
        deployment: my-deployment
        repo: myorg/myrepo
        container: [container1, container2]
        tag: ${DRONE_COMMIT_SHA:0:8}

NOTE: Combining multi container deployments across multiple deployments is not recommended

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_cert: ${KUBERNETES_CERT_STAGING}
        kubernetes_token: ${KUBERNETES_TOKEN_STAGING}
        deployment: my-deployment
        repo: myorg/myrepo
        container: my-container
        namespace: app
        tag: ${DRONE_COMMIT_SHA:0:8}
        when:
            branch: [ staging ]

    deploy-prod:
        image: quay.io/honestbee/drone-kubernetes
        kubernetes_server: ${KUBERNETES_SERVER_PROD}
        kubernetes_token: ${KUBERNETES_TOKEN_PROD}
        # notice: no tls verification will be done, warning will is printed
        deployment: my-deployment
        repo: myorg/myrepo
        container: my-container
        namespace: app
        tag: ${DRONE_COMMIT_SHA:0:8}
        when:
            branch: [ master ]

Required secrets

drone secret add --image=honestbee/drone-kubernetes \
    your-user/your-repo KUBERNETES_SERVER https://mykubernetesapiserver

drone secret add --image=honestbee/drone-kubernetes \
    your-user/your-repo KUBERNETES_CERT <base64 encoded CA.crt>

drone secret add --image=honestbee/drone-kubernetes \
    your-user/your-repo KUBERNETES_TOKEN eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJrdWJ...

When using TLS Verification, ensure Server Certificate used by kubernetes API server is signed for SERVER url ( could be a reason for failures if using aliases of kubernetes cluster )

To do

Replace the current kubectl bash script with a go implementation.
