SaltStack_Notes.txt

-----------------SALT STACK---------
it is a configuration management tools
Python based, open source remote execution tool
remote execution means run commands on various machines in parallel with flexible targeting system

It estalishes the client server model quickly,easily and securely with in a given policy

--------SALT STACK Components-----------

Master
Minion --Client (OS (Redhat,Ubuntu)
Grains--Static information about minion (OS,memory,serial number etc)
Execution Modules--Adhoc commands executed from the command line to one or more target minions

-----Comparison
Scalability- Puppet,SaltStack,Ansible,Chef these are highly scaleable
Easeof setup--Puppet,SaltStack,Chef(Master and Agent Component) but in ansible it is on Master-Node
Availbility:- Puppet( it has multi master archietcure)
              SaltStack( it has multimaster)
              Ansible- it runs with a single active node called Primary instance, if primary instance is down then there
                       is Secondary instance to take its place
              Chef:- Primary and Backup Server 
Management:-  Puppet:- Puppet DSL
              SaltStack- Easy to learn 
              Ansible- Yaml syntax to learn Ansible
              Chef:- Little diffcult as compare to other CMS
InterOperatability:-
            Puppet:-Linux,Windows
            SaltStack:- Master will run on the Linux but client can be windows/Linux
            Ansible:- Supports windows but Ansible server has to be linux
            Chef:- Primary server will be Linux and Client can be windows.
Configuration Language:-
       Puppet:- DSL
       SaltStack:- YAML
       Ansile:- YAML
       Chef:- DSL(Ruby)


Highest Score is given to Ansible
Install Salt Stack 

Master:-

apt install python-pip
pip install salt
To Verify 
 
salt --version

Minion:-

apt install python-pip
pip install salt

salt --version

write following code in /etc/salt/minion file
master: <<IP>>
id: min1


-----On Master machine
To run master component
salt-master -d 
salt-master -l debug
Create a new window to run salt stack adhoc commands
salt-key -L   # this is will show the id of minion under unaccepted key
salt-key -a min1 # to accept the key

salt 'min*' test.ping
salt 'min*' cmd.run 'pwd'
salt 'min*' file.touch '/tmp/1.txt'
salt 'min*' file.write '/tmp/1.txt' 'salt stack'
salt 'min1' grains.items




---On Minion
salt-minion -l debug
