Managing Containers

Demi can manage running containers without going through the full plan-confirm workflow. These are "safe actions" that don't require confirmation.

Safe Actions

Action What it does Needs confirmation?
list Show all containers No
inspect Get detailed container info No
logs View recent log output No
restart Restart a container No
stop Stop a container No
start Start a stopped container No
exec Run a command inside a container No

Examples

You: what's running?
Demi: PostgreSQL is running on port 5432. Nginx on port 9000.

You: restart postgres
Demi: Postgres restarted. Was running since Sun 2026-03-22 02:24:39 UTC.

You: show me the postgres logs
Demi: PostgreSQL started successfully, listening on 5432. Ready to accept connections.
      Last checkpoint completed at 06:30.

You: stop nginx
Demi: Stopped podman-nginx.service.

Running Commands Inside Containers

The exec action lets Demi run commands inside containers. This is useful for querying services directly.

You: how many players are on the minecraft server?
Demi: ★ container (action=exec, name=minecraft, command=rcon-cli list)
      There are 0/20 players online.

You: list all postgres databases
Demi: ★ container (action=exec, name=postgres, command=psql -U postgres -c \l)
      postgres, template0, template1, nurvus

You: update pi-hole's blocklist
Demi: ★ container (action=exec, name=pihole, command=pihole -g)
      Gravity updated. 150,432 domains on blocklist.

Updating Containers

Pull the latest image and restart a container:

You: update jellyfin
Demi: ★ container (action=update, name=jellyfin)
      Updated jellyfin: pulled docker.io/jellyfin/jellyfin:latest and restarted.

This is a safe action and doesn't require confirmation. The container restarts with the new image and existing volumes are preserved.

Removing Services

Removing a service requires confirmation since it's destructive:

You: remove nginx

Demi: Removing nginx:
      - Container will be stopped and removed
      - Port 9000 will be closed
      - Data in /srv/nginx/html stays on disk

      Ready to proceed?

You: yes

Demi: Nginx removed.
