How do I run a Rails server in docker?
In your terminal, change your directory to the docker-rails directory and run the following command: >_ docker build -t rubyapp . To create a container from this image, run the command docker run -p 3000:3000 rubyapp . This creates a container and binds port 3000 of your host computer to port 3000 of the container.
How do I assign an IP address to a container?
You can connect a running container to multiple networks using the docker network connect command. When you start a container using the --network flag, you can specify the IP address for the container on that network using the --ip or --ip6 flags.
