SaltStack Cheat Sheet

This cheat sheet was first published in "SaltStack For DevOps" course.

Installing SaltStack - Ubuntu 12, 14, 16, 18 and 20

Update your key base and source lists from this page according to your distribution.

Example: Ubuntu 18 - Python3

wget -O - https://repo.saltstack.com/py3/ubuntu/18.04/amd64/latest/SALTSTACK-GPG-KEY.pub | sudo apt-key add -

echo 'http://repo.saltstack.com/py3/ubuntu/18.04/amd64/latest bionic main' | sudo tee -a /etc/apt/sources.list

sudo apt-get update

# Master installation
apt-get install salt-master

# Minion installation
apt-get install salt-minion

# Salt ssh installation
apt-get install salt-ssh

# Salt syndic installation
apt-get install salt-syndic

# Salt API installation
apt-get install salt-api

Multi-Platform Installation

Salt Master:

curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P -M

Salt Minion:

curl -L https://bootstrap.saltstack.com -o install_salt.sh
sudo sh install_salt.sh -P

Salt Key Management

# Listing Salt requests
salt-key -L

# Accepting all requests
salt-key -A

# Accepting a single request (from myNode)
salt-key -a myNode

# Removing the key of a Salt 'myNode' Minion
salt-key -d minion_id

# Delete salt key and register it
salt-key -d 'minion' && yes | salt-key -a 'minion'

Debugging

# Debugging the master
salt-master -l debug

# Debugging the minion
salt-minion -l debug

# Restarting the minion without cache
stop master/minion
rm -rf /var/cache/salt
start master/minion

Clearing Cache

# Clearing cache on the minion by removing the cache directory
salt '*' cmd.run 'rm -rf /var/cache/salt/minion/files/base/*'

# Clearing cache the Salt way (using saltutil module)
salt '*' saltutil.clear_cache

# Synchronizes custom modules, states, beacons, grains, returners, output modules, renderers, and utils.
salt '*' saltutil.sync_all

SaltStack Documentation

# Viewing a module documentation
salt '*' sys.doc module_name

#Examples:
salt '*' sys.doc status
salt '*' sys.doc pkg     
salt '*' sys.doc network
salt '*' sys.doc system
salt '*' sys.doc cloud

# Viewing a function documentation
salt '*' sys.doc module_name function_name

# Examples:
salt '*' sys.doc  auth django
salt '*' sys.doc sdb sqlite3

SaltStack Versions

# Salt components report
salt --versions-report
salt --versions

# Master version
salt-master --version

# Minion version
salt-minion --version

SaltStack Modules And Functions

salt '*' sys.list_modules

# list functions
salt '*' sys.list_functions

# synchronising modules on the minion
salt-call saltutil.sync_modules

Compound Matchers

Letter Match Type Example Alt Delimiter?]
G Grains glob G@os:Ubuntu Yes
E PCRE Minion ID E@web\d+.(dev|qa|prod).loc No
P Grains PCRE P@os:(RedHat|Fedora|CentOS) Yes
L List of minions [email protected],minion3.domain.com or bl*.domain.com No
I Pillar glob I@pdata:foobar Yes
J Pillar PCRE J@pdata:^(foo|bar)$ Yes
S Subnet/IP address [email protected]/24 or [email protected] No
R Range cluster R@%foo.bar No

Other examples:

# Examples are taken from https://docs.saltstack.com/en/latest/topics/targeting/compound.html

# Joining

salt '*' saltutil.sync_grains

# Available grains can be listed by using the ‘grains.ls’ module:
salt '*' grains.ls

# Grains data can be listed by using the ‘grains.items’ module:
salt '*' grains.items

# Grains have values that could be called via ‘grains.get <grain_name>’ (path is the name of a grain)
salt '*' grains.get path

Syncing Data

# Syncing grains
salt '*' saltutil.sync_grains

# Syncing everything from grains to modules, outputters, renderers, returners, states, and utils.
salt '*' saltutil.sync_all

Running System Commands

salt "*" cmd.run "ls -lrth /data"
salt "*" cmd.run "df -kh /data"
salt "*" cmd.run "du -sh /data"

# Disable the job
salt '*' schedule.disable_job scheduled_job

# List schedules
salt '*' schedule.list

Working With SLS

# Show SLS
