Rails run with puma in dockerfile and enable https-CodePudding

This is an example of a Dockerfile for ruby on rails project. I want to run it with ssl key and cert

RUN apt-get update -yqq && apt-get install -y npm && npm install -g yarn
RUN apt-get install -y ruby-full
RUN apt install libsqlite3-dev
RUN gem install rails --version=6.1
RUN mkdir /var/app
WORKDIR /var/app
COPY . .
RUN bundle install --without development test

RUN npm install --force
RUN export SECRET_KEY_BASE=...............................
EXPOSE 3000
EXPOSE 80
EXPOSE 443
EXPOSE 8443
RUN rails webpacker:install
#RUN rake assets:clean
RUN rake assets:precompile
CMD rails s -b 0.0.0.0 -e production

CodePudding user response：

FROM ruby:3.0.2

CMD puma -b 'ssl://0.0.0.0:8443?key=yourkey.key&cert=yourcertificat.pem&verify_mode=none' -b 'tcp://0.0.0.0:80' -e production
