Dependabot version updates now proactively updates Docker image tags in Kubernetes manifests.
When specifying the Docker ecosystem in dependabot.yml
include an entry for each directory where a Kubernetes manifest which references Docker image tags is located. Kubernetes manifests can be either Kubernetes Deployment YAML files or Helm charts. Dependabot will parse the unrendered version of the manifest in order to keep your Docker image tags updated.
