Regional data "lock"?

Questions / Help

I believe the preferred way to lock your app to a region is by using volumes.

For example, this is how I recently locked an app to the lax region:

  1. Create a volume in the desired region: fly volumes create VOLUME_NAME --region lax
  2. Mount the volume to your app in your fly.toml file:
[[mounts]]
  destination = "/path/to/volume"
  source = "VOLUME_NAME"

Once you do this and re-deploy your app, the fly regions config will become obsolete. If you try to add a new region, you’ll get a message that regions are being controlled with volumes.
