go-supervise

README

what

Proof of concept and playground for a daemontools written in go. The goal is to have a stable service starter which automagically restarts a service if it has been shut down and log (with logrotation) all output.

You may start up with an empty (or not even existing) service-dir and create the services after starting go-supervise. As soon as a "run" executable is found, the service be started up.

You may delete a service sub-directory (e.g. ~/services/srv1) while go-supervise is running. It will detect the deletion and shut down the service.

For now, go-supervise uses etcd to save known services, because later on

• It should be possible to add a service in etcd database and let go-supervise starts it up on the correct server.
• It should be possible to remove a service in etcd database and let go-supervise shut it down.

etcd is expected on 127.0.0.1:2379, which is default. Later on go-supervise will have a configuration file.

known bugs

If the multilog process is killed, it won't start up again leaving the service without any logging.
