Salt ssh deployment

Simple

Install the salt-ssh.
```
sudo apt install salt-ssh
```
Edit the /etc/salt/roaster.
```
sudo vim /etc/salt/roaster
```

Add the server details if you dont want to type them in the cli.

server1:
  host: 192.168.167.90
  user: root
server2:
  host: www.some_address.com
  user: username
  passwd: password
  timeout: 10
  sudo: true
  minion_ops: dictionary_for_minion_options
  priv: path/to/ssh/private/key.rsa

passwd defaults is for salt-ssh to generate keys

priv defaults to salt-ssh.rsa

Connect to the server and install a package
```
salt-ssh -i server2 pkg.install cowsay
```
The -i is needed on ly the first time we try to connect to the server.

The certificated will be accepted from the remote computer and the pkg.install will pick the default packagemanager and install the application we require.
Verify that the package was install successfuly.
```
salt-ssh server2 cmd.run '/usr/games/cowsay "hello from the server"'
```
salt-ssh will automaticaly pipe to you the result of the command.

Check if the server is responding
```
salt-ssh server2 test.ping
```
salt-ssh will automaticaly pipe to you the result of the command.
The --askpass can be entered to ask for the user pasowrd if it is not specified in the configuration
```
salt-ssh server2 test.ping --askpass
```

Some simple commands

disk.usage
network.interfaces
pillar.item

Salt-ssh raw commands so instead of salt running the commands the commands are executed localy in the system
```
salt-ssh '*' -r 'ifconfig'
```
The '*' indicats that we are targeting all the servers availiable
If you dont want to leave a trace in the system use
```
salt-ssh -W '*' -r 'ifconfig'
```
W stands for whipe

Salt formulas are configuration scripts that automate some of the task you want to do.
- Clone the apache formula on Github
```
cp base/pillar.example /srv/pillar/apache.sls
```
- Then change the vim /srv/pillar/top/sls to enable the formula
```
base:
  "*":
    - apache
```
- Edit the salt master file to add the configuration file for apache
```
  vim /etc/salt/master
```
  Add the config file
```
extra_filerefs:
  - salt://apache/map.jinja
```
- Query the pillar
```
salt-ssh '*' pillar.item apache
```
- Execute the apache sls on the remote system
```
salt-ssh '*' atate.sls apache
```
- The apache is now installed
