Storage layer of Cloudbreak's docker containers - how the elasticity/bursting works as containers are added/removed from scaling

[#1]

Is there any documentation on the storage layer of Cloudbreak docker containers - how the elasticity/bursting works as containers are added/removed from scaling?

[#2 · Accepted solution]

Cloudbreak using overlayfs on the machines. More details about overlayfs here: https://docs.docker.com/engine/userguide/storagedriver/overlayfs-driver/

The containers running net=host so every machine contains one ambari container which is an ambari-agent or an ambari-server.

If you scaling up the cluster then the new container will not start on an existing machine but create a new machine and they will running there.
