Docker is a container-based technology that creates Linux containers. Because it makes deep changes to the system, it might not work perfectly with every virtualization method.
You can use Docker on all virtual servers from Prepaid-Hoster. However, there are a few details you should keep in mind.
Our Recommendation Upfront
If you know you want to use Docker and want to be on the safe side, you should rent a KVM server right away.
| Virtualization Technology | Compatibility |
| OpenVZ (no longer offered) | Possible limitations |
| KVM | No restrictions |
Docker on a Cloud vServer
You can usually run Docker on a Cloud vServer without any problems. However, there are some limitations. Since a Cloud vServer is managed with a container-based virtualization method (OpenVZ7), compatibility issues can arise. It is hard to say in advance which Docker images will work on an OpenVZ 7 server, as it depends on the Docker setup you need.
Another issue can be the kernel. Docker often needs newer kernel components that might not be available in the OpenVZ Virtuozzo kernel.
Docker on a KVM Server
KVM uses full virtualization. This means the guest system is independent of the host system. With a KVM server, you also get your own kernel that isnât shared or virtualized with other customers.
Because of this, you can use Docker without any restrictions on a KVM server.
