Can't precomile sinatra assets via ansible

Question

I am deploying my sinatra project via ansible, and one of the tasks is precompiling assets.

At first I stacked into question how to initialize rbenv properly.

Then, what I did is:

- name: Precompiling assets
  command: bash -lc "cd {{ build_path }} && bundle exec rake assetpack:build"

But then I got error Encoding::UndefinedConversionError at assets/application.js

When I connected by ssh to server and run bundle exec rake assetpack:build - everything worked perfectly. So, I presumed, this is related to setting environment variables

lookup('env', 'LANG') says it is "msg": "ru_RU.UTF-8" but echo $LANG says it's "C" (look there).

Look to this issue. It says:

Ansible sets LANG to C on modules which don't need it

Ansible modules set "$LANG=C" automatically.

Adding environment variable didn't give desired result:

environment:
  LANG: ru_RU.UTF-8
command: bash -lc "cd {{ build_path }} && bundle exec rake assetpack:build"

At the same time shell module seem to know nothing about bundle, so this didn't work as well:

- name: Precompiling assets
  command: bash -lc "cd {{ build_path }} && bundle exec rake assetpack:build"

I tried huge bunch of commands, such as export LANG=ru_RU.UTF-8, command module, shell module, but nothing helps, all my attempts failed miserably.

I do not really know how to workaround this issue.

Need help!

command module is not intended to be used with multiple shell commands. shell module should be used instead:

- name: Precompiling assets
  shell: bundle exec rake assetpack:build chdir={{ build_path }}

Any environment variable that is required before running bundle can be configured as in the next example:

- name: Precompiling assets
  shell: RAILS_ENV=development bundle exec rake assetpack:build chdir={{ build_path }}

The question itself is not about difference between command and shell modules, it is about encoding problems I faced while compiling assets. – Nick Roz Sep 21 '15 at 13:25
shell module does not know about `rake` or `bundle` – Nick Roz Sep 23 '15 at 09:16

I should've changed not only LANG variable, but both LANG and LC_ALL:

- name: Precompiling assets
  environment:
    LANG: "ru_RU.UTF-8"
    LC_ALL: "ru_RU.UTF-8"
  command: bash -lc "cd {{ build_path }} && bundle exec rake assetpack:build"

That worked for me!
