Salt: Module.run does not run the way described in the documentation

Created on 20 Mar 2020 · 7Comments · Source: saltstack/salt

Description of Issue

The documentation located here describes the new and legacy style of passing arguments when using the module.run state function. However, the new style does not behave as described and the legacy style provides a warning that this will be deprecated in the Sodium release. This can be frustrating for users.

Setup

Normal salt installation. Create the following test state to demonstrate.

# test.sls

test_new_style_module_run:
  module.run:
    - test.random_hash:
      - size: 42
      - hash_type: sha256

test_legacy_style_module_run:
  module.run:
    - name: test.random_hash
    - size: 42
    - hash_type: sha256

Steps to Reproduce Issue

Run the state.

# salt \* state.apply test
ip-10-10-10-199.us-west-2.compute.internal:

@frogunder Is the new module.run really working as documented?
I ask because in 3001.1 and the mentioned use_superseded set in the minion config, this example from the official docs does work:

# New Style
test.random_hash:
  module.run:
    - test.random_hash:
      - size: 42
      - hash_type: sha256

but this does not:

Generate a random hash:
  module.run:
    - test.random_hash:
      - size: 42
      - hash_type: sha256

Errors with

                 ID: Generate a random hash
           Function: module.run
             Result: False
            Comment: Module function Generate a random hash is not available

I'm trying to convert a module.run for gpg.import_key, but since that keeps on failing, I made a fall back onto some of the most basic examples, which also fails...

@jtraub91 Thank you for reporting this issue.

I am not able to replicate it, it seems to work correctly for me
Do you have in your minion config file:

use_superseded:
  - module.run

[root@frode1 ~]# salt \* state.apply test

According to the docs https://docs.saltstack.com/en/latest/ref/states/all/salt.states.module.html
you will need to put in your minion config file:

use_superseded:
  - module.run

to use the new style.
When I removed that I did see the same error you are describing.

[root@frode1 ~]# salt \* state.apply test

Thanks.

Oh. Definitely did not have use_superseded. What release are we currently on? I thought we past Sodium. But good to know, sorry I missed that.

For reference, the only thing in my minion config was the master

# cat /etc/salt/minion | grep "^[^#]"
master: localhost

jtraub91 on 20 Mar 2020

Also, I want to point out, in your example, and duplicated on my system with the new config, the new and legacy styles do not behave the same. What explains that discrepancy?

jtraub91 on 21 Mar 2020

# New Style
test.random_hash:
  module.run:
    - test.random_hash:
      - size: 42
      - hash_type: sha256

but this does not:

Generate a random hash:
  module.run:
    - test.random_hash:
      - size: 42
      - hash_type: sha256

Errors with

                 ID: Generate a random hash
           Function: module.run
             Result: False
            Comment: Module function Generate a random hash is not available

@hbokh Sorry for the late reply. It seems to work correctly for me with the two state files you used.

What distro do you see this error on? I used Ubuntu 20 with salt 3001.1 installed.

Thanks.

frogunder on 2 Oct 2020

What distro do you see this error on? I used Ubuntu 20 with salt 3001.1 installed.

On Debian 9 "Stretch" and Salt 3001.1

hbokh on 3 Oct 2020

I just tried on Debian 9 with Salt 3001.1 and it seems to work correctly for me.

root@ip-10-27-59-63:~# salt \* grains.item lsb_distrib_description
test:
    ----------
    lsb_distrib_description:
        Debian GNU/Linux 9.2 (stretch)
root@ip-10-27-59-63:~# salt \* grains.item saltversion
test:
    ----------
    saltversion:
        3001.1
root@ip-10-27-59-63:~#

I do not see the error you are describing, so not sure what is causing your issue.
