Docker build failure on windows with docker

[petre-enciu]

I tried to build the project with docker compose for windows, following the steps described in the README file.
First, there is a problem with some files:

1. README file: git clone https://github.com/consul/consul.git. it should be git clone https://github.com/code4romania/consul.git
2. docker-compose.yml - there is no ports binding for the database service. ports statement should be added, ex:
   ports:
   • "5432:5432"

At the build phase:

1. docker-compose build
   gives this error:
   **_=> ERROR [app 13/16] RUN gem install bundler 28.4s

---

[app 13/16] RUN gem install bundler:
28.03 ERROR: Error installing bundler:
28.03 The last version of bundler (>= 0) to support your Ruby & RubyGems was 2.4.22. Try installing it with gem install bundler -v 2.4.22
28.03 bundler requires Ruby version >= 3.0.0. The current ruby version is 2.6.7.197.

---

failed to solve: process "/bin/sh -c gem install bundler" did not complete successfully: exit code: 1_**

As workaround, I have manually added the bundler version in Dockerfile (line 38):
RUN gem install bundler -v 2.4.22
The build works as it should.

2. docker-compose up
   gives this error:
   [+] Running 15/1

In docker-desktop the database container is running, but the container associated with the rails server is always down and cannot be stared.

Please Help!
