Managing SSH keys and the associated files is a key task that needs to be performed in most infrastructure at present to facilitate a number of functions with remote access between servers. Although this task can be achieved by propagating files to the minions using the file module, Salt has a better way to do it using SSH-specific modules. In this recipe, you will learn how to use these modules.
Configure two minions called
salt-minionandbackup-server. Configure theserver_typegrain ofsalt-minionto have the valueappand the backup server's value to bebackup.Create a new state called
sshauth, and create two files inside this directory calledpubkey.slsandknown_hosts.sls. Also create a directory calledsshkeysinside thesshauthdirectory.We will assume that the
groupsandusersmodules, configured in the last recipe, have been applied on both the minions.On the
salt-minionminion, change to thestg-appuser, and run the following...
