Volume only persists files you write to it, what is the use case of this 'web server config'?
Remember that you will need to redeploy your app after attaching a volume.

Its not clear to me

If by configurations, you're talking about config files inside your web server, then I'm not sure they will persist with a volume since they're probably rebuilt at every restart/redeploy.

If you're talking about files that you've uploaded through your own app, then mounting a volume to that path will persist those files between restart/redeploys.

Your concern is dataloss, by attaching a volume you will need to redeploy your service, that will cause an initial dataloss since you still don't persist any files.

Alright
Thank you

My concern isnt data loss per say, its about how I setup the domain, predeploy, builds etc

Oh, you're talking about Railway service settings.
Don't worry, they will be saved if you don't delete that service.

If you wanna pause a service just remove it's active deployment

Click on it -> Deployments tab -

Click on the service -> deployments tab -> three dots on the active deploy -> remove

Oh great. So all I have to do is remove the current deployment thats all?

That means to bring it back, I have to redeploy it again right?

yeah!

Sure. Thanks
