test run
salt "*" state.apply test=True
check if minion has packages to update
salt '*' cmd.run "yum check-update > /dev/null;echo $?"
Add minion to master
On client:
set master in /etc/salt/minion, maybe also define some role(s) restart salt-minion
On master:
salt-key
if hostnamed indeed shows up,
salt-key -a hostname
and then
salt hostname state.highstate
Remove minion from master
single line per minion
salt "*" grains.item nodename group os osrelease --out=txt
(for a list of items use grains.items
Apply just one part of role
Assuming you have foo.sls in roles/
salt '*' state.apply roles.myrole.foo
Change minion hostname
On minion:
- hostname new.host.name
- update /etc/hostname
- update /etc/salt/minion_id
- restart salt-minion
On master: rename the key ( /srv/salt/pki/master/minions/old.host.name )
Rendering SLS 'base:roles.foo.bar' failed: Jinja variable 'dict object' has no attribute 'blergh'
Unless you made a typo, your minion probably doesn't have access in pillar
multiple parameters
salt '*' param1,param2 arg1,arg2
define a grain on minions
salt minion1 grains.setvalue role foobar
set role from init.sls
roles: grains.present: -value: somerolename
