Docker container running but can't view in browser
docker, ruby, ubuntu
Solution
I found my problem. the solution was to run the docker as production and not as development.
in Dockerfile, instead of:
CMD ["bundle", "exec", "rails", "server"]
I changed to:
CMD ["bundle", "exec", "rails", "server", "-e", "production"]
and that solved my problem
Problem
I'm new with Docker and i'm trying to run ruby app inside a docker. So i created a ruby app that work and run fine, I also created a image and a docker that when i run and build them it's running just fine. After I running the docker it's shown like it's running without problems, i get an IP from `docker inspect` and the port shown at `docker ps -a` as 3000. when i open the IP:port at the browser I can't see nothing. here is my docker file: ``` > FROM ruby:latest > > # Set the working directory to /app WORKDIR /app > > # Copy the current directory contents into the container at /app ADD . /app > > RUN echo 'debconf debconf/frontend select Noninteractive' | > debconf-set-selections RUN apt-get update \ > && DEBIAN_FRONTEND=Noninteractive apt-get install -y \ > sqlite3 \ > thin \ > nodejs \ > apt-utils \ > && bundle install > # --no-install-recommends apt-utils sudo > > > #RUN sudo -H cp config/initializers/rack_attack.rb config/initializers/rack_attack.rb > > # Install any needed packages specified in requirements.txt > # RUN pip install -r requirements.txt > EXPOSE 3000 > > CMD ["bundle", "exec", "rails", "server"] ``` Edit: I tried also with 'Expose 3000' and also run with '-p' flag. When i run 'docker ps -a' the ports are: '0.0.0.0:32768->3000/tcp'. For 'docker inspect' i get the IP: '172.17.0.2' but when i go to 'http://172.17.0.2:3000/' in the browser i see nothing. NEW EDIT I discover that the docker is running as tcp6 (IPv6), how can i configure it to be tcp? .
