# mailcow-agent-cli — publish a control-bus command from inside a service
|
|
# container, optionally collecting one reply. Same wire protocol as the Go
|
|
# agent (see internal/envelope/envelope.go).
|
|
#
|
|
# Usage:
|
|
# mailcow-agent-cli send <service> <cmd> [json-args]
|
|
# Fire-and-forget. Prints the number of subscribers reached.
|
|
# mailcow-agent-cli call <service> <cmd> [json-args] [timeout-seconds]
|
|
# Publish + wait for one reply on its private reply list. Prints the
|
|
# reply envelope JSON on stdout.
|
|
#
|
|
# Requires the `redis-cli` binary to be present in the calling container.
