Security Considerations

Kubernetes Web View exposes all Kubernetes object details via its web frontend. There are a number of security precautions to make:

  • Do not expose Kubernetes Web View to the public without authorization (e.g. OAuth2 redirect flow or some authorizing web proxy).
  • The default RBAC role for kube-web-view (provided in the deploy folder) provides full read-only access to the cluster --- modify it accordingly to limit the scope.
  • Design and understand your access control: decide whether you use kube-web-view only locally (with personal credentials), have a central deployment (with service credentials) to multiple clusters, use oauth2 for cluster access via --cluster-auth-use-session-token, or have it deployed per cluster with limited access.
  • Understand the security risks of exposing your cluster details to Kubernetes Web View users --- you should only trust users who you would also give full read-only access to the Kubernetes API.
  • Check your Kubernetes objects for potential sensitive information, e.g. application developers might have used container environment variables (env) to contain passwords (instead of using secrets or other methods), mitigate accordingly!

Kubernetes Web View tries to have some sane defaults to prevent information leakage:

  • Pod container logs are not shown by default as they might contain sensitive information (e.g. access logs, personal data, etc). You have to enable them via the --show-container-logs command line flag.
  • Contents of Kubernetes secrets are masked out (hidden) by default. If you are sure that you want to show secrets (e.g. because you only run kube-web-view on your local computer (localhost)), you can disable this feature via the --show-secrets command line flag.

Note that these are just additional features to prevent accidental security issues --- you are responsible for securing Kubernetes Web View appropriately!
