rust-pm - Intro

This is a pocket process manager. At some point it will be a better imitation of systemd Take a look at this .

Using it is very simple, just drop a rust-pm.toml in the same folder your rust-pm starts with a config like:

toml server-port = "localhost:4000" [bad_sleeper] # Process name command = "./bad_sleeper.py" # right now support 0 args commands max_retries = 3 # 0 means forever

And with luck you open your browser at localhost:4000 and will see something like:

json [{ "command" : "./bad_sleeper.py", "max_retries" : 0, "name" : "bad_sleeper", "status" : { "meta" : 1, "state" : "running" } }]

rust-pm start and watch the process. If it fails it starts another instance for maximum max_retries times.

Ideas

By now the stdin, stdout and stder are piped. We may change it to inherited, so the rust-pm output is in fact the process output. It depends on what we will do for logging.

WARN

This is a early stage project, Not used in production yet.

TODO

• Augment the API to support scalling processes down and up.
• Implement 0 max_retries to mean infinite. DONE
• Allow configuration of workdir for processes.
• Invest in logging? DONE. So far with simple writeln! since specific threads handle stdout.
• Implement fern to replace bizarre writeln!
• Add command line parser to specify config file. So rust-pm can be put on $PATH and run with any config file.
