I’m trying to deploy an app on Railway, and I need to create both a server and a database.
Both the server and the database need to be specific versions.
The app server should run Node: v18.12.1 (18.x.x), and the database should be MySQL: 8.0.33.
Additionally, the server needs to be Ubuntu: 22.04.
I understand that I need to do this using a Dockerfile, but I'm not quite sure how to go about it.
Could you please help me?
Thank you so much in advance!

This feels a little XY.
Do you need that specific version for ubuntu?
Anyways, you will need to have 2 services. One for the app and one for the db. For the DB, you might not need a special docker file, and can just find one that is officially supported (from docker hub stuff) and use that as your image.
For the app, you would do a similar thing to start. Pick a version you want to pin to, and then build from there.
So https://hub.docker.com/_/node/ and https://hub.docker.com/_/mysql/
And then for the node, you would do something like
FROM node:18
# Everything else ...
But ummmm. Why are you trying to pin to such specific versions? It just feels strange.

Thanks for your response.
I need such specific versions because the project is quite old and runs with those versions of Node and MySQL. I might also need a specific version of Yarn to install the dependencies. It's a React project so old that it uses class components and also implements SSR with an Express server.
In other words, it's an Express server that renders a page made with React, so I can deploy it directly on Railway without needing another host like Vercel, for example.
My idea was exactly as you mentioned: one instance for the database and another for the SSR server.
One more question, can automatic backups of the database be configured?
Thanks in advance for the information.
