Installation

Opscode Chef

We provide runit-man cookbook to automate setup of runit-man using Opscode Chef.

Manual installation

Usually You should install both runit-man and thin gems to run this tool fine.

gem install runit-man thin

Pragmatic approach is to setup runit-man as runit service like this:

runit-man -p 14500 -r

This command installs runit-man as runit service (using default folders /etc/sv/ and /etc/service/).

Look at {file:INSTALL.md} for details.

rackup configuration

Take a note that runit-man gem also provides config.ru rackup configuration file. It's useful for running under unicorn/rainbows etc. runit-man --rackup=command option does cd config.ru directory && set environment && exec command.

Customization

This tool can provide additional information or actions through it's Web page.

View names and content of files that related to concrete service

For each known runit service this tool looks for ./runit-man/files-to-view/ folder. Every symlink there will be shown as link to view target file content.

Show links that related to concrete service

For each known runit service this tool looks for ./runit-man/urls-to-view/ folder. Every file ended with .url will be shown as link to view target location (location should be written as content of this file).

Indicate services with any of watched files are modified since service startup

For each known runit service this tool looks for ./runit-man/files-to-watch/ folder. Symlink targets there will be tested for its mtime to be less than service start time. Service will be indicated as dangerous (as red color) to restart if any watched file is modified since service startup.
