I would like to share the output of a command from one node to the other on running salt "*" state.apply.

My current solution involves mine.send and mine.get:

$ cat top.sls
base:
  'master*':
    - states.master*

  'worker*':
    - states.worker*

$ cat states/master.sls
save:
  module.run:
    - mine.send:
      - foo
      - mine_function: cmd.shell
      - name: whoami

$ cat states/worker.sls
load:
  file.managed:
    - name: /tmp/a.sh
    - contents: {{ salt['mine.get']("*", "foo").values() | first }}

On first run, I get the following error for the “worker” node:

worker-0:
    Data failed to compile:
----------
    Rendering SLS 'base:states.worker' failed: Jinja variable No first item, sequence was empty.; line 7

---
[...]
load:
  file.managed:
    - name: /tmp/a.sh
    - contents: {{ salt['mine.get']("*", "foo").values() | first }}
---

On second run it works as expected.

I am assuming that the problem is that the mine.get does not wait for the mine.send but it tries to fetch the variable on creating the template.

Any suggestions?

Thanks
