Migration of Squirrels

[AndreasAakesson]

Acorn is currently not stable enough to not crash, but good enough to run on OpenStack. It's fun to see users capturing new Squirrels 😸 , but sad to see them escape when the VM dies 😿 .

My current idea is something like this:

• Create a route to something like /api/squirrels/migrate/:ip (or ?ip= until parsing is implemented)
• When booting a new instance with a clean Bucket, the "admin" just enters http://<current instance>/api/squirrels/migrate/<old instance>, and all the squirrels will clone and jump into the new bucket.
• To avoid being exploited, we just add an bool if it's been a migration, if true, just return 404 (or a more suited status code).

This will not help if the old instance has already crashed tho (which it shouldn't soon™).

Any better ideas?

I'd suggest putting in the URL to migration server via a file on the memdisk and just do it once at boot.

Later we can add it as a parameter to openstack- I know how we can get that into the instance
