This plugin allows to update a Kubernetes deployment.
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:
- mytag
- latest
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:
- mytag
- latest
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:
- mytag
- latest
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:
- mytag
- latest
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:
- mytag
- latest
when:
branch: [ master ]
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>

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 )
- After deployment inspect you pod for name of (k8s) secret with token and ca.crt
kubectl describe po/[ your pod name ] | grep SecretName | grep token
(When you use default service account)
- Get data from you (k8s) secret
kubectl get secret [ your default secret name ] -o yaml | egrep 'ca.crt:|token:'
- Copy-paste contents of ca.crt into your drone's KUBERNETES_CERT secret
- Decode base64 encoded token
echo [ your k8s base64 encoded token ] | base64 -d && echo''
- Copy-paste decoded token into your drone's KUBERNETES_TOKEN secret
Replace the current kubectl bash script with a go implementation.
