Templating config file with docker

We have been using ansible to set up application, but now we're moving to docker, so I have a question about generating sphinx.conf (or any text file) from template.

I have template like this for jinja2 (which is supported in ansible):

{% for locale in locales %}
answers_{{ locale }}
{% endfor %}

And locales var which is defined by locales: {"ru", "en", "de"}

So as a result i have:

answers_ru
answers_en
answers_de

Now is the question: what is the best way to do it using docker?

Solution

  • Found a solution using simple bash script, so I didn't even alter the template.

    #!/bin/sh

cat > /etc/sphinxsearch/sphinx.conf

for LOCALE in ru en de ;
do
    sed "s/{{ locale }}/${LOCALE}/g" ./template/index.conf.template >> /etc/sphinxsearch/sphinx.conf
done
