Ansible templates - " gets suibstituted with ' ?

[Hristo Stoyanov]

Hi all,

I am trying to generate Dockerfiles with Ansible template -  see the role and the template in Ansible Galaxy: peruncs.docker 

So this:

...

instruction: CMD

value: '["/var/lib/{{postrges_version}}/bin/postgres"]'

...

ends up like:

....

 CMD  '['/var/lib/9.4/bin/postgres']'

...

and I lost the my  ", which renders the Dockerfiles useless!

Any help ? How can I convince Jinja to not substitute " with ' ? I tried  \" , |safe filter, even {% raw %} - it's just keep doing it ...sigh

Thanks in advance!
