wheels deploy server

Host-level operations that don't fit in the app/proxy/accessory model.

From the shell, use the flat aliases wheels deploy exec and wheels deploy bootstrap. The nested wheels deploy server <verb> form is shadowed by the CLI's own top-level server command (Lucee instance management) and prints that command's help instead (#2677, #2690). The nested form remains for direct callers that bypass the shell, such as MCP.

Verbs

| Verb | Shell form | Purpose | |------|------------|---------| | exec | wheels deploy exec <command> | Run a command on every host (optionally filtered). | | bootstrap | wheels deploy bootstrap | Install Docker on a fresh host (idempotent). |
