inv2ips(1)

inv2ips(1) is a small utility that outputs CSV IP addresses for a given service name.

Install

$ git clone ssh://git@git.evantann.com:2222/egtann/inv2ips.git
$ sudo make install

Check the man pages for inv2ips(1) and inventory.json(5) for detailed usage information and examples.

Usage

Given an inventory.json file that looks like this:

{
	"my-app": ["10.128.0.1", "10.128.0.2"]
}

$ inv2ips my-app
10.128.0.1,10.128.0.2

This may be useful to dynamically update addresses in environment files or flags using their service names, such as appending them to a config file during deploy:

$ echo "IPS=$(inv2ips -p 3000 inventory)" >> config.env

It may also be useful when combined with Up to deploy services or environments by name:

$ up -t $(inv2ips production) deploy
