SUMMARY

I've come across the situation when ansible won't include my vars_files if they are encrypted via vault even if I specify vault_password_file. In the example below everything works fine if vars.yml is not encrypted. But as soon as I encrypt vars.yml I get the error (see below). Maybe I should use some other technique to inject vault encrypted variales into my container build process?

STEPS TO REPRODUCE

ansible-container --debug  build --no-cache

EXPECTED RESULTS

Sucessfull build

@s-sokolko do you have minimal POC in form of repo ?

Documentation might be outdated, but looking at https://docs.ansible.com/ansible-container/container_yml/reference.html#supported-directives

vars_files	List of variable files to use for Jinja2 template rendering while parsing container.yml
vault_files	List of Ansible vault files, where each entry is a file path. Files are decrypted in the conductor at playbook runtime, making variables available to playbooks and roles.
vault_password_file	Path to a file containing a clear text password that can be used to decrypt any vault files.

I do not see in your example above definition for vault_files

s-sokolko · 2018-07-27T05:35:40Z

@Voronenko thank you for the quick reply!
I tried using vault_files option in my container.yml, but I end up having the 'variable is undefined error' as below

`fatal: [dante]: FAILED! => {"failed": true, "msg": "'proxy_users' is undefined"}
to retry, use: --limit @/tmp/tmplW_UUJ/playbook.retry

ERROR Conductor exited with status 1`

As I looked through the code of ansible-containers cli it seemed to me that vault_files are not used when I run ansible-container build.
Anyway I created a repo with my failing container, you can clone in using
git clone https://github.com/s-sokolko/dante-container.git
And then perform the build command in the root of this repo to see it failing:
ansible-container build --no-cache
Any help will be truly appreciated!

Voronenko · 2018-07-27T07:25:47Z

If you would create minimal POC in form of repo, I can debug.

Take a look how it was done in this issue: #944
Person created small workable POC of problem - the only thing left was - debug and fix.

s-sokolko · 2018-07-27T07:32:40Z

@Voronenko here is the repo https://github.com/s-sokolko/dante-container
I tried to make it look like the example repo provided by you

Voronenko · 2018-07-27T07:34:09Z

Thanks!

s-sokolko · 2018-10-01T09:16:57Z

@Voronenko is there any progress on the issue? Maybe I can help with some extra information?

Voronenko · 2018-10-01T10:03:31Z

I have it in backlog, but need to find opportunity window between my commercial work schedule.

ITBlogger · 2018-10-09T16:47:28Z

The docs specifically state that ansible-container only decrypts files with the run command, not build, which seems not great at all, but that probably explains your issue

Voronenko · 2018-10-09T16:48:58Z

That's offtopic, but I prefer hashicorp "application" roles approach to prepare images that get prepared upon run - that makes it a little more robust.
