Hello

Im new to awx - and am wondering if it is possible to have a dynamic inventory where the hosts are containers from kubernetes?

Thanks

Oh, you know what, I forgot an important details. If you’re using any decently recent version of Ansible, these Kubernetes plugins are already shipped with Ansible. All you need to do is put in the plugin form of the file into your source control.

[https://docs.ansible.com/ansible/2.6/plugins/inventory/openshift.html](https://docs.ansible.com/ansible/2.6/plugins/inventory/openshift.html)

Actually, I had an open question of what the best way to encrypt the token for OpenShift is doing this. I don’t think the vault tricks with with the inventory plugin files.

Thanks Alan

This looks very promising.

I’m missing a piece of the puzzle though.

I see that, in order to enable the k8s plugin I need to add it to the ansible.cfg file. So I have the following in a local ansible.cfg file:

[inventory]  
enable\_plugins = k8s

For the plugin settings, as specified by [https://docs.ansible.com/ansible/2.5/plugins/inventory/k8s.html](https://docs.ansible.com/ansible/2.5/plugins/inventory/k8s.html), I have the following:

A file named k8s.yaml, with the following contents:

```auto
plugin: k8s
connections:
    host: [https://192.168.64.4:8443](https://192.168.64.4:8443)
    token: xxxxxxxxxxxxxxxx
    ssl_verify: false

```

So, my question is, assuming the plugin is enabled, and the settings are correct, how do I write an inventory file - or specify in a playbook - to use this plugin?

I have the following playbook. I’ve set the hosts to default, as I have a k8s namespace called default. However, when I run this it doesnt work

The main thing you need to do is create an inventory source for an inventory which sources from a project. For this source, provide the relative location for k8s.yaml inside of your repo. Then click the button to sync that source, and after its finished you should be able to see logs from the inventory update.

You don’t actually need to modify ansible.cfg here. Ansible tries a series of standard plugins by default. One of those is a router for all other officially shipped plugins, that plugin sees “plugin: k8s” inside your file (with that file name) and then sends it to the k8s plugin.

I still anticipate further pain points after you’ve done this. See:

[https://github.com/ansible/ansible/pull/49901](https://github.com/ansible/ansible/pull/49901)

In my own personal testing, I’ve been having authentication problems when counting on the provided parameters to be used. I suspect that it may have to be used via providing a kube config file, and pointing the inventory file to that file.

This does make it a bit clearer.

However, I’m unable to select the k8s.yaml file in the source editor window.

I have the k8s.yaml in git:

But I’m unable to select this in the Awx:

So it looks like the problem is the awx docker image doesnt have the openshift python module installed:

Yes, if it’s not officially vendored, as in this case, you have to shell into the container, active the Ansible virtual environment (or a custom venv) and install it there.

Thanks Alan

It looks like the docker container is hardened, so I do not have the permissions.
