Hello,

You can run mysqldump locally and upload the resulting file to S3, we don't currently have any working templates to achieve this automatically.

Scratch that, looks like a template for it was published today - https://railway.app/template/BZJOmR

thank you very much! I still have two further questions:

why is it possible to run the command from this node application but not from my java application?

what happens if this github code is updated. will it also just redeploy in my environment? if yes, that would be a very high security risk for me..

1. Don't really know what you mean, you haven't provided enough information.

2. If you (the owner) push code to whatever branch you have connected to your Railway service the Railway service will deploy the new code, if anyone else pushes code you will need to manually approve the deployment within the dashboard for security reasons.

I want to do the backup in my own application. the problem is, that mysql is not installed on the instance my machine is running on. how can I install it? I think the template you provided installs it using a dockerfile. is there any other possibility to install dependencies on the instance?

I'm not sure why you would want to install mysql dump alongside your Java app, but if you do, you would want to write your own Dockerfile as well.
