Docker mirror / sync between two servers?


Recommended Posts

Hi,

Is it possible to mirror a few Docker containers natively with unRAID between two servers in different locations?
Possibly master-slave relationship that a container is always the copy of the original and is switched on in case of problems of the original ?
My idea was:
I have a unRAID server
A friend has a unRAID server
each has a Nextcloud and MariaDB container
These should be on the other's server as a real time copy. No matter if a job is executed daily or live.
If someone's Nextcloud container fails because e.g. the house burned down, the friend's container automatically takes over.
