In following file:
Dockerfile(from image: line 3).ruby-versionGemfile
$ touch .env.perso
$ docker-compose build
$ docker-compose run web bash
# inside container:
$ gem install rails
# Create your Rails app with prefered options (see below for suggested config)
$ rails new . # ....
$ exitUncomment in Dockerfile lines containing:
COPY Gemfile /webapp/Gemfile
COPY Gemfile.lock /webapp/Gemfile.lock
RUN bundle install
# If you installed JS bundling in your app, also uncomment:
COPY package.json /webapp/package.json
COPY yarn.lock /webapp/yarn.lock
RUN yarn installYou might need to get back ownership of your files (Ref needed)
find . -user root | xargs sudo chown your_host_user_name:your_host_user_nameThen rebuild your image:
$ docker-compose buildYou can now use your app:
# Start App
