Install Salt Master :
sudo yum install https://repo.saltstack.com/yum/redhat/salt-repo-latest-2.el7.noarch.rpm
sudo yum clean expire-cache
sudo yum install salt-master
sudo yum install salt-minion
sudo yum install salt-cloud
For Automatic Minion configuration we need to use saltify provider from salt.
Reference :
https://docs.saltstack.com/en/latest/topics/cloud/saltify.html
Lets start with the creation of saltify provider file :
vi /etc/salt/cloud.providers.d/saltify.conf
************
my-saltify-config:
minion:
master: ip_of_salt_master
driver: saltify
************
now let us create a map file, it basically creates a map between salt profile and minion, The profile name 'setup-minion' will have to defined in the profile section.
you can list down all the minions that you need to configure in this file, I am just adding one minion as an example :
vi /etc/salt/saltify-map
************
setup_minion:
- minion-name:
ssh_host: ip_of_minion
ssh_username: root
key_filename: /root/.ssh/id_rsa
************
I am usin key_filename here, because i have ssh keys setup between the master and minion, if you do not have that you can use username and password.
as mentioned above, now let us create the profile :
vi /etc/salt/cloud.profiles.d/saltify.conf
************
setup_minion:
provider: my-saltify-config
************
now that we have all the configuration files ready, let us run a below command which will setup a minion for us :
salt-cloud -m /etc/salt/saltify-map -l debug
this will ask you for a confirmation about minion being setup, once you hit proceed you are all set.
I have added debug just in case it fails the output will help you to understand the error.
