Today we try adding Postgresql to the Rails 7.1 Docker stack, and it kind of just works!

That's right! Today we use the cool new Rails 7.1 Docker stuff to add postgres into the mix, without having to figure out how to make it all work on the deployment server :D

Thanks again for these timely videos. I just containerized my entire rails dev setup. I do it outside of the individual rails app though, in a dev workspace so I don't have to repeatedly set up new instances when I create a new app to play around with. I added postgres, redis, mailhog, minio, and elasticsearch. Hopefully with this new direction in 7.1 and dockerd, they get to something like sail in Laravel.

Nice intro to docker-compose with Rails. Just to note that we needed to to add "libpq-dev" to the Dockerfile "apt-get install" to make it work (I believe because we were using a later posgtres image).

Wow, great content and lots of it :)

Do not think you need db:create
db:prepare runs create, migrate and seed

[benmercerdev]

What triggers the migration when you run docker-compose build && docker-compose up after generating the posts scaffold?

Hi, I followed the tutorial and it worked great but when I try to change to the development environment the containers run perfectly fine but when I head to localhost it says that localhost did not send any data.

For macOS `docker-compose` is now a parameter to `docker`. `docker-compose up` becomes `docker compose up`.

Great video, a question what happend with the rails db:migrate RUN command?

@Deanin Can you tell me how to deploy the same Web App in kubernetes. Urgently required.

Can you do this video combined with EC2 instance on Amazon deployment?

[waishnavdeore]

Please make video on deploying Rails 7 app on Digitalocean droplet (without Hatchbox)

[kefahngwei]

Such a great video especially with the environment setup, I followed step-b step but I don't know why when I try access my localhost it shows connection error even though docker-compose up says everything is okay

[flipflop]

Thanks a lot for this!
Did you plan to make a video on how to use an Amazon RDS instance with postgres instead of a volume ?
It would be mind blowing !

Thanks again :)

Hello, can you tell how you install rails 7.1? From rvm or using curl with rails official repo?

[rickbacker]

Do we realy need "rails db:create" in docker-entrypont? I thouth that "rails db:prepare" is creating db if it's not created..

[AlejandroVazquez-dlnf]

Hello!
I have this error
HTTP parse error, malformed request: #<Puma::HttpParserError: Invalid HTTP format, parsing fails. Are you trying to open an SSL connection to a non-SSL Puma?>
I cleared my cache and cookies and still have, do you know what can I do?

Why rails new appname --main not working on my laptop?

[rajarshiganguly]

Thanks for the helpful video, but in this case rails had to be installed in the system instead of dockerizing the installation
