CLI

The iii CLI: run projects, trigger functions, and manage iii itself.

Ask the installed binary for its exact command and flag surface:

iii --help
iii <subcommand> --help

The generated CLI reference publishes the same surface.

Subcommands

Subcommand	What it does
iii compose	Run the Compose daemon, prepare registry packages with build, or supervise a project with --up.
iii trigger	Invoke a registered function on a running engine.
iii project	Scaffold projects and generate Docker assets.
iii console	Launch the iii web console.
iii cloud	Manage hosted iii deployments.
iii update	Update iii and its managed support binaries.

iii worker was removed in 0.23. Add and manage project workers through compose::*; see Workers. The worker::* function surface was removed with it.

Running iii with no subcommand starts only the engine from ./config.yaml or --config. Use iii compose --up for the normal project lifecycle:

iii compose build --file worker-compose.yaml
iii compose --namespace dev --up --file worker-compose.yaml

Managing iii Cloud deployments

The iii cloud command group manages hosted deployments. See Deployment.

iii Cloud availability may vary by account and release.

Updating iii

iii update updates iii and support binaries installed with it. Worker package versions are pinned inside worker-compose.yaml; update one with compose::update:

iii trigger -n dev compose::update worker=state
iii trigger -n dev compose::update worker=state@0.22.2

Run iii update --list-targets to list the binaries the installer can update.
