loch functions update

loch functions update

Change the resources, handler or variables of a function

Synopsis

Change a function: only the given flags change. --env sets a variable (others are kept), --unset-env removes one. A running function restarts with the new configuration; a stopped one stays stopped. --mcp-invocable / --no-mcp-invocable decide whether AI agents (loch mcp) may invoke it. Secrets are changed with loch functions secrets set. On the custom runtime (provided), --handler "" resets the handler to its default, bootstrap.

loch functions update <name> [--memory] [--timeout] [--cpus] [--tmp-size] [--handler] [--env K=V]... [--unset-env K]... [flags]

      --handler string          New handler (provided: "" resets it to bootstrap)

      --mcp-invocable           Let AI agents (loch mcp, functions_invoke) invoke it
      --memory string           Memory limit in MB, or with a unit (512M, 1G); see loch functions config
