How to update a Deployment imageΒΆ
To update the Docker image for an existing deployment:
from pykube import Deployment, HTTPClient, KubeConfig
new_docker_image = "hjacobs/kube-web-view"
api = HTTPClient(KubeConfig.from_file())
deploy = Deployment.objects(api).get(name="mydeploy")
deploy.obj["spec"]["template"]["spec"]["containers"][0]["image"] = new_docker_image
deploy.update()
Note that the call to deploy.update()
might fail if the resource was modified between loading and updating.
In this case you need to retry.
