For the most current list of commands, flags, and defaults, ask the binary directly:
Each subcommand’s help also provides the defaults and environment variables that affect each command.

​
Trigger a function from the CLI

iii trigger <function-id> [arg=value ...] invokes a registered function against a running engine. The engine routes the call to whatever worker registered the function; no trigger registration is involved.
For the full invocation surface, payload formats, fire-and-forget, queue-routed actions, and the equivalent SDK call from worker code, see Triggers / Call a function directly.

​
Subcommands

Running iii with no subcommand starts the engine from ./config.yaml (or the path passed to --config); pass --use-default-config to start with the built-in defaults instead.

​
Managing iii Cloud deployments

The iii cloud subcommand group will manage hosted iii deployments. See Deployment for details about the iii cloud.
iii’s cloud will be available soon.

​
Updating iii

iii update refreshes iii and its managed binaries to their latest versions. This is distinct from iii worker update, which refreshes pinned worker versions inside a project.
Specific targets can be updated individually via iii update [target]. Run iii update --list-targets to see the list of targets.
