upstart-local-bridge: Bridge between Upstart and a local client socket
NAME
upstart-local-bridge - Bridge between Upstart and a local client socket connection.
SYNOPSIS
upstart-local-bridge [OPTIONS]...DESCRIPTION
upstart-local-bridge listens on a local domain socket for name=value pairs and creates init(8) events for them.The local unix domain socket can be either named or abstract.
OPTIONS
- --any-user
- By default the bridge will only accept connections from clients running under the same user ID as the bridge itself. This option allows connections from any user.
- --daemon
- Detach and run in the background.
- --debug
- Enable debugging output.
- --event event
- Specify name of event to emit on receipt of a name=value pair.
- --help
- Show brief usage summary.
- --path path
- Specify path for local/abstract socket to listen on. If the first byte of path is an '@', the socket will be created as an abstract socket.
- --verbose
- Enable verbose output.
EVENT DETAILS
The following environment variables are added automatically to the event to be emitted, with the name=value pair being added as the last variable.
- •
- SOCKET_TYPE=unix
- •
- SOCKET_VARIANT=[named|abstract] Sub-type of socket.
- •
- CLIENT_UID=UID User ID of connected client.
- •
- CLIENT_GID=GID Group ID of connected client.
- •
- CLIENT_PID=PID Process ID of connected client.
- •
- SOCKET_PATH=PATH
EXAMPLES
- upstart-local-bridge --event=foo --path=/var/foo/bar
-
Listen on local socket
/var/foo/bar
and when a name=value pair is read, emit an event of the form:
-
foo SOCKET_TYPE=unix SOCKET_VARIANT=named SOCKET_PATH=/var/foo/bar name=value
-
- upstart-local-bridge --event=bar --path=@/var/foo/bar
-
Listen on abstract socket
@/var/foo/bar
and when a name=value pair is read, emit an event of the form:
-
bar SOCKET_TYPE=unix SOCKET_VARIANT=abstract SOCKET_PATH=@/var/foo/bar name=value
-
NOTES
- •
- If a named local socket is specified, all path elements except for the last must already exist before the bridge starts.
LIMITATIONS
- •
- Only a single client connection is serviced at any one time.
