Because it makes deep changes to the system, it might not work perfectly with every virtualization method.\nYou can use Docker on all virtual servers from Prepaid-Hoster. However, there are a few details you should keep in mind.\nOur Recommendation Upfront\nIf you know you want to use Docker and want to be on the safe side, you should rent a KVM server right away.\nVirtualization Technology\nCompatibility\nOpenVZ (no longer offered)\nPossible limitations\nKVM\nNo restrictions\nIs Docker compatible with OpenVZ and KVM?\nDocker on a Cloud vServer\nYou 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.\nAnother issue can be the kernel. Docker often needs newer kernel components that might not be available in the OpenVZ Virtuozzo kernel.\nDocker on a KVM Server\nKVM 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 isn\u00e2\u0080\u0099t shared or virtualized with other customers.\nBecause of this, you can use Docker without any restrictions on a KVM server.\nIf you have any questions about this topic, please feel free to contact our support team. Keep in mind that we cannot guarantee specific compatibility on Cloud servers.","schema":null,"facts":[],"links":[]}}
