Access listed grain values

Question

I'm trying to access listed grain values from state file, need help on this.

State file is as below

{% set list = grains['selinux'] %}

echo {{ list }}:
  cmd.run

But when i run the state file got the error.

# salt '*' state.sls list_grains
client1:
    Data failed to compile:
----------
    Rendering SLS 'base:list_grains' failed: mapping values are not allowed in this context
ERROR: Minions returned with non-zero exit code
[root@server ~]# vim /srv/salt/list_grains.sls

grain values accessed are as below

# salt '*' grains.item selinux
client1:
    ----------
    selinux:
        ----------
        enabled:
            True
        enforced:
            Permissive

Answer 1

The selinux grain is a dictionary/map like:

selinux:
  enabled: True
  enforced: Permissive

So in a state ID you cannot have dictionary/map. You can pick the required dictionary key like list.enabled or list.enforced.

For example, the below state ID will output Permissive:

{% set list = grains['selinux'] %}

echo {{ list.enforced }}:
  cmd.run

If you want to get the complete dict as output, you can use a module like test.echo:

{% set list = grains['selinux'] %}

show-selinux-grains:
  module.run:
    - name: test.echo
    - text: "{{ list }}"
