salt stack - SaltStack: $HOME of users which does not exist yet

I create a user foo on a minion. The minion evalutes /etc/default/useradd. This means the salt master does not know whether the new $HOME will be /home/foo or in our case /localhome/foo.How can I get the $HOME of user foo as jinia variable?I need it in a systemd service file.I would like to avoid custom pillar data, since this is redundant. Is there a way to get it via grains? Does it work during boostrapping? First the user foo needs to be created, then the systemd file can be created by looking up the $HOME of foo...This would work if the us...Read more

salt stack - IPtables management with SaltStack

I'm trying to configure a flexible iptables management solution with SaltStack, but I find it harder than I thought it would be.My main requirement: to be able to have a pillar where I keep a list of IPs, which should be whitelisted for SSH access on all minions. This list of IPs will of course change every now and then: some IPs get added, some IPs are removed. The problem that I'm facing is with the removed IPs - when I remove them from the pillar file, SaltStack doesn't remove the actual whitelisting from the minions.The only workaround I co...Read more

Reusing salt state snippets

In my salt state files I have several occurrences of a pattern which consists of defining a remote repository and importing a gpg key file definition, e.g.import_packman_gpg_key: - name: rpm --import - unless: rpm -q gpg-pubkey-1abd1afb-54176598packman-essentials: pkgrepo.managed: - baseurl: - humanname: Packman (Essentials) - refresh: 1 require: - cmd: import_...Read more

winding-up dynamic states in Salt for changed environments

Consider some dynamic state shapes based on certain grain / pillar values. A webserver could for example add additional site definition for debug endpoints:{% if grains['dev'] %}/etc/nginx/sites-enabled/logaccess.conf: file.managed: - source: salt://some/path/logaccess.conf{% endif %}this works fine unless for example a dev server changes its role and becomes a productive one. There is no state left, and the file resides on the minion.I could of course add a counterpart/etc/nginx/sites-enabled/logaccess.conf:{% if grains['dev'] %} more

job scheduling - salt-master is not receiving scheduled job event fired on salt-minion

I would to like to ask you for a help. I use saltstack as a job scheduler for slaves (minions) and I would like to be able to see on master job events fired on minion.My setupJob is scheduled on salt-master using a pillar for given minion. Pillar is:schedule_returner: mongoschedule: cmd: function: args: - date +%s >> /tmp/job_runs minutes: 1 maxrunning: 1Scheduled job is executed without any problem on minion.

salt stack - Saltstack taking 30+ seconds

I have essentially a barebones saltstack "cluster" running. In fact, it's actually a master and a minion on the same host machine. This is really a 2 part question.1) The salt-master takes a really long time to boot. Like 2+ minutes. The debug logs look like it's got several threads going in a loop loading/reloading configs:[DEBUG ] Reading configuration from /etc/salt/minion.d/master.conf[DEBUG ] Reading configuration from /etc/salt/minion.d/master.conf[DEBUG ] Using cached minion ID from /etc/salt/minion_id:[DEBUG ] ...Read more

configuration management - Why isn't my Salt minion showing any pillar attributes?

I've been through the salt and pillar walkthroughs and in general, everything works as expected with my setup. In fact, there isn't anything that I'm aware of that isn't working properly...until now.This is my first foray into using the pillar system. I have access keys that I am trying to protect so I'd like for pillar to allow me to keep tabs on which minions get copies of them.Here is my setup.Directory structure:[root@master config-mgmt]# tree /srv/pillar/srv/pillar├── awscreds.sls├── data.sls├── dev└── top.sls/srv/pillar/top.sls file:[ro...Read more
