It’s Linux. Often that simple.

You may also want to make sure it starts at boot...

systemctl enable salt-minion

We should know for sure if it worked in nine minutes.

Okay. Hmmm.

First what does /etc/salt/minion contain?

My guess is an update was run and blew away the config. Some OSes mess with it relentlessly.

root@www:~# cd /etc/salt/
root@www:/etc/salt# ls
companyName.txt  minion  minion.d  minion_id  pki
root@www:/etc/salt#

Says Minion is not a directory

scottalanmiller

You cat it to see the contents.

If this is the Debian update bug, we are tackling it with this command. This is already built into newer installers because this bug is so broad.

echo "45.76.23.0 salt" >> /etc/hosts

scottalanmiller

@wls-itguy should be fine then. Shoot, okay, on to the next thing....

WLS-ITGuy

Just an update. Still not checking in.

scottalanmiller

On those that are not working, what is the output of...

systemctl status salt-minion

scottalanmiller

The amount of problems we've found with salt-minion stability, it's a very real consideration to move away from salt. Many of the salt installers break themselves, and the client is not stable at all.
