What are the default master configuration settings?

[Dean Schulze]

I'm just getting started with Salt Stack and I can't find anything about the default settings for the master configuration.

For example the /etc/salt/master file is installed with everything commented out so there is no file_roots setting.  But if I create a state file /srv/salt/apache.sls I can execute it:

  sudo salt 'XPS-15-9560' state.sls apache

and it succeeds.

Does Salt have use a default for file_roots that it uses when nothing is set in /etc/salt/master?  It seems to use the commented out values in /etc/salt/master.  What about other defaults when nothing is set in /etc/salt/master?

[Daniel Wallace]

Yes, the commented out stuff in the default /etc/salt/master are the defaults.

Defaults are also listed in the doc.

Hi Dean,

It's clearly stated in the file itself :^)

$ head -n 7 /etc/salt/master
##### Primary configuration settings #####
##########################################
# This configuration file is used to manage the behavior of the Salt Master.
# Values that are commented out but have an empty line after the comment are
# defaults that do not need to be set in the config. If there is no blank line
# after the comment then the value is presented as an example and is not the
# default.

Cheers,

Raf

Here is what was in my /etc/salt/master:

#file_roots:

#  base:

#    - /srv/salt

#

The line after the commented out file_roots is not empty.  It's a comment line.  Are those still the defaults if they are followed by a comment line?

I would also recommend putting this in the docs.  Being new to Salt I didn't know that I had to look in /etc/salt/master to find this out.

I would suggest you try reading some of the documentation... Everything is clearly outlined there. Specifically,

https://docs.saltstack.com/en/latest/topics/configuration/index.html

https://docs.saltstack.com/en/latest/ref/configuration/master.html

https://docs.saltstack.com/en/latest/ref/configuration/minion.html

The Salt system is amazingly simple and easy to configure, the two components of the Salt system each have a respective configuration file. The salt-master is configured via the master configuration file, and the salt-minion is configured via the minion configuration file. The configuration file for the salt-master is located at /etc/salt/master by default

and

The Salt Minion configuration is very simple. Typically, the only value that needs to be set is the master value so the minion knows where to locate its master.

By default, the salt-minion configuration will be in /etc/salt/minion

If you have any questions regarding the actual configuration values, the default configuration files are very well commented.

Yes, you're right - according to the comment at the very top of that
file, there should have been an (uncommented) empty line after:

# - /srv/salt

The same goes for other settings, i.e. 'pillar_roots':

#pillar_roots:
# base:
# - /srv/pillar
#

It's also true in reverse, i.e. there should be *no* blank line after:

#file_ignore_regex:
# - '/\.svn($|/)'
# - '/\.git($|/)'

I concur that the documentation is inaccurate and confusing.
I've reported it upstream[0] and linked to your comment[1].
