# Example: Call Salt API Webhook from internal network:

# Run shell commands on minions

# UPDATE SALT ON MINIONS

# Target Minions with a specific salt version

# Target minions without a specific salt version

# Download the salt install script on all minions
salt -C 'G@os:Ubuntu and not G@saltversion:2016.11.10' cmd.run 'curl -o install_salt.sh -L https://bootstrap.saltstack.com'

# Update the salt minions 
# HINT: This will only install the salte minionon (it would update the salt master executables only if they are already installed)
salt -C 'G@os:Ubuntu and not G@saltversion:2016.11.10' cmd.run 'sudo sh install_salt.sh git v2016.11.10'

# OPTIONAL: Update the salt master
# ATTENTION: This makes only sense on the salt master server(s)
sudo sh install_salt.sh -M git v2016.11.9

# The minion update on the salt master if any is installed
sudo sh install_salt.sh git v2016.11.9

# Get the minion id (= hostname)
salt.grains.get('id')
# Example:
{% do online_releases.append(salt.pillar.get('hosts:' + salt.grains.get('id') + ':online_target_release')) %}


# get the network ip
salt.network.interfaces()['eth0']['inet'][0]['address']


# get the netmask as  e.g.: 255.255.255.0
salt.network.interfaces()['eth0']['inet'][0]['netmask']
