This is a complete set of saltstack formulas that I developed for personal usage. Some of them are available as independent ones either as personal repos or official saltstack-formulas.

All of them share a rationale that I'll document explicitly (TBD).

The subdirectories *-saltstack-formula could be stacked in your file_roots to give you ready-to-use states to manage your systems.

General customization strategies

  • Use pillar data. This is the absolutely recommended way to use the formulas. In most occassions all you need is to fill some of the key-values shown in the pillar.example file. If you feel that a certain value should be there then don't hesitate to propose an enhancement.

  • Use the extra_conf key that in some cases is present in the pillar to add arbitrary configuration lines in the templates provided. This is a way to have a better customization without over-populating the pillar with new key-values.

  • Add new subdirectories under files in addition to default. This new subdirectories will contain different files to be used in certain conditions. This selection mechanism is based by default in the ìd grain of the minion (i.e. if there's a new subdirectory named minion01 then the formula is going to look there first for that minion). This selection behavior can be extended to make it depend on any sorted list of grains, defined by the key files_switch.

    For example, let's define in pillar something like:

    .. code:: yaml

      files_switch: ['id', 'os_family']

    Let's have this files directory structure:

    .. code:: asciidoc

      |-- minion01
      |       `-- etc
      |            `-- foo.conf.jinja
      |-- Debian
      |       `-- etc
      |            `-- foo.conf.jinja
      `-- default
              |-- etc
              |    |-- foo.conf.jinja
              |    `-- bar.conf.jinja
              `-- usr/share/thingy/*

    With this, we have the following:

    • if the minion id is minion01 then files/minion01/etc/foo.conf.jinja is going to be used

    • else if the minion os_family is Debian then files/Debian/etc/foo.conf.jinja is going to be used

    • else files/default/etc/foo.conf.jinja is going to be used

    Beware: this is not designed to substitute pillar data. Remember that pillar has to be used for information that it's essential to be only known for a certain set of minions (i.e. passwords, private keys and such).

  • As a last resort you can actually fork the formula to suit your needs, keeping an eye for further improvements to merge into yours. Of course any pull- request that you can bring back it would be taken in account ;-)

Useful commands

Add remotes for the repo-per-formula and add them as subtrees:

FORMULAS="apache mysql nginx php5 shorewall sudo system users varnish zabbix"
for i in $FORMULAS
    git remote add -f $i-saltstack-formula \$i-saltstack-formula.git
    git subtree add -P $i-saltstack-formula $i-saltstack-formula master

Pull all the repo-per-formula subtrees:

FORMULAS="apache mysql nginx php5 shorewall sudo system users varnish zabbix"
for i in $FORMULAS
    git subtree pull -P $i-saltstack-formula $i-saltstack-formula master
