Migrating or restoring croit container

Sometimes, you want to migrate the croit container to a different host, or the current host is not available anymore, and a redeployment of the container is needed.

If the container is healthy (you want to voluntarily migrate it, and no crash happened), make a backup of your current configuration using your preferred method (cloud or local):

Backups view (Croit->Backups)

In the new host, pull and run a new docker container using the same version you had in the previous one:

docker create --name croit-data croit/croit:latest
docker run --cap-add=SYS_TIME -v /var/run/docker.sock:/var/run/docker.sock --net=host --restart=always --volumes-from croit-data --name croit -d croit/croit:latest

The important match should be the ceph version, please use the proper tag croit/croit:latest.<ceph version> if you are not running the latest ceph version yet.

From the UI in the new container, restore the backup using the same method you chose before:

Optional

If you plan to use a different IP address for the new host, server, or virtual machine, you will need to update the new IP address in the configuration settings (Config → Networks → Boot IP). After making this change, reboot each node one by one via SSH. This will ensure they pick up the new management node IP through the kernel command line.
