README

This is an example repository for working with rails and postgres, and setting them up using docker-compose.

To run this app, do the following.

1. Install docker

2. Run docker-compose up

3. This would run the web service in a container and postgres in a container.

4. Would look something like this.

5. This would take a while the first time.

6. Now we need to create db before we can go any further. For this we'll connect to the docker container. 6. In another terminal run docker ps 7. 8. Copy the container id for web, and connect to container by running this command. docker exec -it 1597728759c0 sh 9. You'll be connected to the docker container. 10. Run rake db:create && rake db:migrate

7. Go to http://localhost:3000/ and see if everything is working.

8. Run all your rails commands in the container itself.

9. Try running rails g scaffold blog title:string body:string

10. Go to http://localhost:3000/blogs and see if everything works.

what

Hi, thanks for the guide. I'm coming from Golang/Nodejs stack, and am attempting to learn RoR for the first time. Not urgent, but just thought you might be interested in knowing there's a breaking issue here.

I'll keep working on the side and if I've found a solution I'll submit a PR.

how to reproduce

1. clone repo
2. run docker-compose up
3. observed

Issue linking up containers through aliases in /etc/hosts

Thanks for this example:

Not sure if you're interested but I ran in to an issue with it. To me it looks like an issue with docker-compose. I opened an issue and a SO.

• docker/compose#7442
• https://stackoverflow.com/questions/61721667/docker-compose-not-adding-dependent-container-to-etc-hosts

I also thought you might have found a way around it.
