Process supervisor in Go
Warning
This project is currently in progress
taskmaster is a school project, part of my cursus at 19. The directives are to write a supervisor-like process manager in any language with a server running child processes based on a configuration file and a client which sends basic instruction (restart, reload, kill, etc) in any language.
I decided to write the project in Go since it is a language I am currently learning and wish to become better at. For the the client-server communcation, I went for Google's gRPC through UNIX sockets since it fits my needs perfectly.
Usage of taskmasterd
-conf string
config file path (default "/etc/taskmaster.yaml")
-socket string
path of the server's unix socket (default "/tmp/taskmaster.sock")
Example:
$ taskmasterd -conf ./prod.yaml -socket /tmp/taskmaster-prod.sock
Usage of taskmasterctl
-socket string
path of the server's unix socket (default "/tmp/taskmaster.sock")
Example:
$ taskmasterctl -socket /tmp/taskmaster-prod.sock
