How to specify deployment strategy?

Hey, previously i'm a fly io user and I want to migrate to Railway. Is it possible to define the deployment strategy? My use case is that I want to make sure that previous instance is stopped before new instance got deployed. Thanks!

Solution:

that can be done by setting RAILWAY_DEPLOYMENT_OVERLAP_SECONDS to 0 in the service variables https://docs.railway.app/develop/variables#user-provided-configuration-variables...

Thanks! Is it have the same guarantee as attaching dummy volume to the service?

To prevent data corruption, we prevent multiple deployments from being active and mounted to the same service. This means that there will be a small amount of downtime when re-deploying a service that has a volume attached

yes, please read that variables description in the doc I linked I'm curious what's your usecase?

yes2 i've read the description, just need to confirm 👍 I'm running a simple service that aggregrate some data (e.g. simple data counter) from postgres, this service fetch previous state of the data hence it will become invalid (the count data) if there are two services running
