The image also runs on its own, outside the cluster it shows: on a machine of its own, say, as a dashboard for a cluster a team shares. Give it a kubeconfig, and it shows one of its contexts to everyone who signs in, the same way it would from inside the cluster.
Then open http://localhost:8080.
  • LUMOVI_CONTEXT picks the context to show; without it, the kubeconfig’s current context.
  • The cluster is called by its context’s name, unless LUMOVI_CLUSTER_NAME says otherwise.
  • Lumovi listens on port 8080 (LUMOVI_PORT), and answers /healthz for health checks.
Every setting is an environment variable here: see Configuration.

​
Whose credentials it uses

That depends on how people sign in, exactly as in a cluster:
  • With tokens (the default), people’s requests carry their own tokens. The kubeconfig only says where the cluster is and how to trust its certificate.
  • With single sign-on or a proxy, Lumovi uses the kubeconfig’s credentials to impersonate people. Give it a service account’s, with permission to impersonate users and groups, and nothing more.
The image has only Node.js and helm, so credential plugins like aws eks get-token, gke-gcloud-auth-plugin or kubelogin aren’t in it. Use a kubeconfig whose user has a token or a client certificate.
Paths in a kubeconfig (to a certificate, say) are read relative to the kubeconfig’s own folder, so mount those files next to it, or embed them with the *-data fields. The image runs as a non-root user (UID 65532), so make sure that user can read what you mount.

​
With single sign-on

-e LUMOVI_OIDC_CLIENT_SECRET without a value passes the variable on from your shell, so the secret stays out of your shell history. Put TLS in front of Lumovi with a reverse proxy, and set LUMOVI_URL to the address people open. See Single sign-on for registering Lumovi with your provider.

Pin a version

Without a tag, Docker pulls latest, the latest release. Pin a version to know what runs:
Sessions live in Lumovi’s memory, so restarting the container signs everyone out.
