I formatted your post. Please, do it for us next time, because it would be pretty hard to read your question without that for anyone. Use markdown code block syntax or the </> button to start a code block for any temrinal output, code or logs. More help here:

Do you really get the error while building the image and not when starting the container? Nothing should try to connect to a database and you only have an “npm install” command running in build time. The server would start wen you start the container. And I don’t see any error message in your log indicating on the client side that MySQL is not running, except that the MySQL container indeed shows it could not start due to incompatible data directory.
This part seems to be clear:
mysql-1 | 2026-02-17T10:55:21.534813Z 1 [ERROR] [MY-014061] [InnoDB] Invalid MySQL server downgrade: Cannot downgrade from 90600 to 80408. Downgrade is only permitted between patch releases.

This indicates you had a newer MySQL version installed and you used the same data for an older version.
riaron777:
server-1 | errno: -3008,
server-1 | code: 'ENOTFOUND',
server-1 | syscall: 'getaddrinfo',
server-1 | hostname: 'MySQL-8.4',
server-1 | fatal: true
These show that you used “MySQL-8.4” as hostname on the server side, but your compose service is called “mysql”, so you should configure that for hostname in the server container.

Why port 3307? MySQL listens on port 3306 by default, not 3307. I don’t see any 3307 or any other port in your compose under the mysql service, but if you forgot to share that you added port forward, port forward is only needed when you want to access the service from your browser for example. Services communicate over Docker networks, so you can continue using port 3306 for internal connections.

Please, edit your post and use code blocks in Markdown or use the </> button to starta new code block. See how I edited your first post.
But… just because you change the port in the compose yaml, MySQL will still listen on its default port, which is port 3306 so you will need to use that for internal connection.
