Saltstack master has dynamic ip address

Question

What is the best way to manage a minions master location when the master within SaltStack has a dynamic IP address?

Is there a way to automatically update the minions (master) IP address?

Don't use a dynamic IP address? – ewwhite Nov 18 '13 at 15:40 — ewwhite, Nov 18 '13 at 15:40

You can use a hostname in the minion config that is dynamicaly updated each time the ip changes:

master: your_hostname.noip.com

There is a free service like noip to achieve this.

Since this question has been raised salt-ssh appeared on the stage: http://docs.saltstack.com/en/latest/topics/ssh/. It is production ready since release 2014.7.0 (October 2014).

In this situation the master uses SSH to connect to the minions. No need for the master to have a static IP address any more.

You don't even need salt installed on the minion. You only need Python on the minion.
