I am playing around with salt and what my problem is launching instance from Amazon EC2 AMI results minion keys being the same. How do I refresh individual minion to get it's new identity (key)?

  1. Stop the minion service.

    service salt-minion stop
    
  2. Delete old identity

    rm /etc/salt/pki/minion/minion.pem
    rm /etc/salt/pki/minion/minion.pub
    cat /dev/null > /etc/salt/minion_id
    
  3. Make sure salt will begin on startup

    chkconfig salt-minion on
    
  4. Create your a new AMI

Give the following command a try:

sudo salt 'name_of_host_whose_keys_you_wish_to_regenerate' saltutil.regen_keys

Based on user325017's answer.

I adapted this for Ubuntu Bionic Beaver 18.04, since it has systemd:

#!/usr/bin/env bash

systemctl stop salt-minion
rm /etc/salt/pki/minion/minion.pem
rm /etc/salt/pki/minion/minion.pub
cat /dev/null > /etc/salt/minion_id
systemctl enable salt-minion
systemctl start salt-minion

On Debian 10 and possibly others, the files have changed location. Do this:

# Stop the service.
service salt-minion stop

# Delete key files.
rm /var/lib/salt/pki/minion/minion.pub
rm /var/lib/salt/pki/minion/minion.pem

# Edit minion_id to the desired name you want to appear in saltstack.
# Or you can rm this file and the minion will create it containing the hostname. 
vi /etc/salt/minion_id

# Start the service.
service salt-minion start
-1

Following @user325017 answer for Windows, tweak step 2 with:

Remove C:\salt\conf\pki\minion\minion.pem Remove C:\salt\conf\pki\minion\minion.pub Edit c:\salt\conf\minion, and update the line with "id:"
