< p > cdist comes with simple built-in tag based inventory. It is a simple inventory
with list of hosts and a host has a list of tags.
Inventory functionality is still in < strong > beta< / strong > so it can be used only if beta
command line flag is specified (-b, --beta) or setting CDIST_BETA env var.< / p >

2019-04-23 18:55:23 +00:00
< p > The idea is to have simple tagging inventory. There is a list of hosts and for
each host there are tags. Inventory database is a set of files under inventory
database base directory. Filename equals hostname. Each file contains tags for
hostname with each tag on its own line.< / p >
< p > Using inventory you can now configure hosts by selecting them by tags.< / p >
< p > Tags have no values, as tags are just tags. Tag name-value would in this
context mean that host has two tags and it is selected by specifying that both
tags are present.< / p >
< p > This inventory is < strong > KISS< / strong > cdist built-in inventory database. You can maintain it
using cdist inventory interface or using standard UNIX tools.< / p >

< p > cdist can be used with any external inventory where external inventory is
some storage or database from which you can get a list of hosts to configure.
cdist can then be fed with this list of hosts through stdin or file using
< strong > -f< / strong > option. For example, if your host list is stored in sqlite3 database
hosts.db and you want to select hosts which purpose is < strong > django< / strong > then you
can use it with cdist like:< / p >
