ssm

Yet another service manager.

Services

A service is a script in the ssm's init.d directory.
By default it's /etc/ssm/services for system services and $XDG_CONFIG_HOME/ssm/services for user ones.

Global settings

• cgroups = 0 — Enable cgroup-related features.

Service config

Mandatory options:

• service_command = /usr/bin/example -a --long-arg "parameter"

Optional settings (incomplete list):

• service_respawn = no — Restart the service. Takes no, always, on-failure and on-success.
• service_workdir = /
• service_pidfile — If the service manages its own pidfile, set this.
• service_pidfile_timeout = 15 — How long to wait for the service to create its pidfile.
• service_pidfile_remove_stale = yes — Remove stale pidfiles before spawning the service process.
• service_logfile_out = $logdir/$service_name.log — Logfile for output.
• service_logfile_err = $service_logfile_out — Logfile for stderr.
• service_stop_timeout = 30 — How long to wait after sending the stop command.
• service_ready_timeout = 15 — How long to wait till the service is ready, in seconds.
• service_stop_signal = 15 — Which signal to send to the service when stopping.
• service_reload_signal = 1 — Which signal to send to the service when reloading.
• service_cgroup_exclusive = no — Refuse to start the service if the cgroup is not empty.
• service_cgroup_wait = no — Wait on the entire cgroup to die when stopping the service.
• service_cgroup_strict = 1 — Refuse to do anything if the service's recorded PID is both running and not in the service's appropriate cgroup. This usually means you've either found a bug or something bad happened to your system.
• service_cgroup_kill = no — Kill the entire cgroup when stopping the service.
• service_cgroup_kill_signal = 15 — Which signal to use for that.
• service_cgroup_cleanup = no — Kill the entire cgroup on watchdog cleanup. Note that it is distinctly not the same as killing the cgroup on stopping.
• service_success_exit = 0 — Array. Which exit codes to treat as successful termination. Only works for managed services (With no custom pidfile).
• service_oneshot = no — The service is supposed to do something and die instead of daemonizing.
• service_signals_passthru — Array, empty by default. Which signals should the svc pass directly to the service mainpid. This is dangerous, use with caution.
