How to find and open databases running in local containers with Masume

Detect databases in running Docker or Podman containers and open one in the client.

Short answer: Start the Docker or Podman container that runs your database; then run masume --detect to list databases in running containers and in the current kubectl context; choose the database from the list and connect. All steps.

Who it is forA developer whose test database runs in a container and who does not remember its port or name.

The problemLooking up container ports and credentials by hand each time wastes time during local work.

The outcomeMasume lists the databases it finds, and you open one with a click or key press.

What you need first

  • A terminal on macOS, Linux, or Windows
  • A database you can reach, or a local SQLite file
  • One install method: Homebrew, npm, Go 1.27 or later, or a release package

Steps

  1. Start the Docker or Podman container that runs your database
  2. Run masume --detect to list databases in running containers and in the current kubectl context
  3. Choose the database from the list and connect
  4. Run a query to confirm you are on the expected database

Prompt for your agent

In the masume repo, run `masume --detect` and report the databases it lists. Expected output: a list of detected databases. Verify that the database you expect appears, and that the container is running.

Caveat. Kubernetes detection uses kubectl port-forward as described in the README, so it depends on your kubectl context and access.
