06. Salt file server

salt-master file server configuration:

Salt runs a file server to deliver files to minions.
This file server is built into the master daemon and does not require a dedicated port.
Default location is /srv/salt.
Configured via the file_roots option inside the master configuration file.

# more /etc/salt/master 
file_roots:
 base:
  - /srv/salt

# more  /srv/salt/salt.txt 
hello-world

salt execution module cp (on the master):

# sudo salt "minion_1" cp.get_file salt://salt.txt /tmp/salt.txt
minion_1:
    /tmp/salt.txt

verify on salt-minion:

# ls -l /tmp/salt.txt 
-rw-r--r-- 1 root root 13 Jun 26 01:17 /tmp/salt.txt
# date
Mon Jun 26 01:17:48 PDT 2017
# more /tmp/salt.txt 
hello-world
