Salt: Check for pillar file's existence?

[hazaelsan]

I don't think there's a way to check if a pillar file exists using just Jinja. This would be useful to have per-node pillar override files that can be conditionally included, since trying to include a non-existent pillar results in an error.

External pillars are the closest workaround.

This does sound reasonable. Thanks for the request!

This seems to for me

Setting a pillar:
pillar_key: pillar_value

Checking if pillar is defined in a state file
{% if pillar['pillar_key'] is defined %}

@hazaelsan can you validate for you use case?

[hazaelsan]

Apologies for the ludicrous delay :/

http://grokbase.com/t/gg/salt-users/148m57601n/pillars-conditionally-add-pillar-file-in-top-sls is pretty much the same scenario, the workaround listed there is:

{% if salt['file.file_exists')('hosts/{0}.sls'.format(grains.host)) %}
'{{ id }}':
   - hosts.{{ grains.host }}
{% endif %}

I'd love to see a proper solution that doesn't suffer a race condition though :)

It would still be nice to have this without the previously mentioned workarounds or using ext_pillars like pepa or something.

+1 for this.

I've spent quite some time developing something based on the workaround that @hazaelsan mentioned a few years ago but is compatible with git_pillar .
This seems to work for us:

{%- set curpath = opts.pillar_roots[saltenv] %}
{%- for gitfsremote in curpath %}
{%-   if salt['file.file_exists']('{0}/hosts/{1}.sls'.format(gitfsremote, opts.id)) or
      salt['file.file_exists']('{0}/hosts/{1}/init.sls'.format(gitfsremote, opts.id)) %}
    - hosts.{{ opts.id }}
{%-   endif %}
{%- endfor %}
