Junos:

You can use any junos version and any device running Junos.
The only requirement is to enable netconf on your Junos devices:

set system services netconf ssh
commit

Salt master:

Install Salt master:

You can install Carbon but we highly recommand Nitrogen.
Nitrogen should be available on pypi by July 2017.
Meanwhile, install Nitrogen on the Master using the branch 2017.7 from the github Salt repository:

# pip install git+https://github.com/saltstack/[email protected]

# salt --version
salt 2017.7.0-202-g3c8dee0 (Nitrogen)

Configure Salt master:

Salt master configuration file:

# more /etc/salt/master 
file_roots:
 base:
  - /srv/salt

pillar_roots:
 base:
  - /srv/pillar

engines_dirs: 
  - /srv/engines

engines: 
  - junos_syslog: 
      port: 516

reactor:
  - 'jnpr/syslog/*/UI_COMMIT_COMPLETED':
        - /srv/reactor/on_commit.sls

pillars:

top file:

# more /srv/pillar/top.sls 
base:
  'ex4200-7':
     - ex4200-7-details
  'vsrx01':
     - vsrx01-details
  'vqfx01': 
     - vqfx01-details

pillars for vqfx01:

This vqfx is a vagrant box.

# more /srv/pillar/vqfx01-details.sls 
proxy:
      proxytype: junos
      host: 192.168.233.158
      username: root
      port: 8331
      passwd: Juniper

Start the salt-master:

to start it with a debug log level, use this command:

# salt-master -l debug

Salt minion:

we do not install minions on junos devices as we are using a salt proxy.

Salt proxy:

Junos proxy provides:

Salt proxy configuration file:

Get the ip address of the master:

# ifconfig ens33 | grep "inet addr"
          inet addr:192.168.233.17  Bcast:192.168.233.255  Mask:255.255.255.0

On the server that will run the salt proxy:

# more /etc/salt/proxy
master: 192.168.233.17
multiprocessing: False

salt proxy requirements:

On the server that will run the salt proxy, install junos-eznc python library:

sudo apt-get install -y python-dev libxml2-dev python-pip libxslt1-dev build-essential libssl-dev libffi-dev
sudo pip install junos-eznc jxmlease cryptography==1.8.1

Start Salt proxies:

You need one salt proxy process per device.
to start the proxy for vqfx01 with a debug log level, use this command:

sudo salt-proxy -l debug --proxyid=vqfx01

if you prefer to run it as a daemon, use this command:

sudo salt-proxy -d --proxyid=vqfx01
sudo salt-proxy -d --proxyid=ex4200-7
sudo salt-proxy -d --proxyid=vsrx01

Accept the public keys:

On the master, you need to accept the minions/proxies public keys:

To list all public keys:

# salt-key -L

To accept a specified public key:

# salt-key -a vqfx01 -y
# salt-key -a vsrx01 -y
# salt-key -a ex4200-7 -y

Or, to accept all pending keys:

# salt-key -A -y

Verify the keys:

# salt-key -L

Test:

# sudo salt "vqfx01" test.ping -d
test.ping:

    Used to make sure the minion is up and responding. Not an ICMP ping.

    Returns ``True``.

    CLI Example:

        salt '*' test.ping

# sudo salt "vqfx01" test.ping
vqfx01:
    True

Junos execution modules:

https://docs.saltstack.com/en/latest/ref/modules/all/salt.modules.junos.html

Examples:

junos.cli

# salt "vq*" junos.cli -d
junos.cli:

    Executes the CLI commands and returns the output in specified format.     (default is text) The ouput can also be stored in a file.

    Usage:

        salt 'device_name' junos.cli 'show system commit'

        salt 'device_name' junos.cli 'show version' dev_timeout=40

        salt 'device_name' junos.cli 'show system alarms' 'xml' dest=/home/user/cli_output.txt


    Parameters:
      Required
        * command:
          The command that need to be executed on Junos CLI. (default = None)
      Optional
        * format:
          Format in which to get the CLI output. (text or xml,             default = 'text')
        * kwargs: Keyworded arguments which can be provided like-
            * dev_timeout:
              Set NETCONF RPC timeout. Can be used for commands which
              take a while to execute. (default = 30 seconds)
            * dest:
              The destination file where the CLI output can be stored.               (default = None)
