Hosts

A host is one container engine Gantry talks to. Add as many as you like; they all share one sidebar and dashboard.

Host types

• Local Docker — the daemon on your Mac (Docker Desktop, Colima, OrbStack, …). Gantry auto-adds a Local host on first launch; override the socket path in Settings → General if needed.
• Docker over SSH — a remote daemon reached through SSH. Gantry tunnels the Docker socket; nothing needs to be exposed publicly.
• apple/container — Apple's native runtime. See apple/container.

Adding an SSH host

Click Add Host… at the bottom of the sidebar and choose SSH Docker Host. You can import an entry straight from your ~/.ssh/config, or fill in host, port and user manually. Authentication can be:

• Automatic — your SSH agent and default keys.
• Key file — a specific private key (with an optional passphrase).
• Password — stored in your login Keychain if you opt in.

On first connection Gantry shows the server's host-key fingerprint for you to trust (trust-on-first-use), the same model as OpenSSH.

Per-host tools

• Overview — CPU/memory gauges, disk usage, and host facts (OS, architecture, Docker version).
• Host terminal — an interactive SSH shell in its own window.
• Host files — an SFTP browser to download files from the remote host (SSH only).
• Reconnect, reorder, remove — from the host's hover menu in the sidebar.
