A User Service is an automatically managed process on Zo Computer that has a public endpoint. These services will be restarted if they crash, and they will persist across restarts of Zo Computer. They are intended for long-running services that you want to expose via a public URL or TCP address (web/API servers, databases, SSH server, etc). Services should bind to the PORT environment variable.
Parameters
Identifier of the service to update.
New unique label (per host), if changing.
New localhost port to expose, if changing (injected as the PORT env var).
New entrypoint, if changing.
New working directory, if changing.
Replacement environment variables, if changing (PORT will be overridden).
