Docker Containers
On Linux, Docker uses resource isolation of the Linux kernel, to allow independent "containers" to run within a single Linux kernel instance.
Docker containers are supported on MLNX_OFEDusing Docker runtime. Virtual RoCE and InfiniBand devices are supported using SR-IOV mode.
Currently, RDMA/RoCE devices are supported in the modes listed in the following table.
Orchestration and Clustering Tool | Version | Networking Mode | Link Layer | Virtualization Mode |
Docker | Docker Engine 17.03 or higher | SR-IOV using SR-IOV plugin along with docker run wrapper tool | InfiniBand and Ethernet | SR-IOV |
Kubernetes | Kubernetes 1.10.3 or higher | SR-IOV using device plugin, and using SR- IOV CNI plugin | InfiniBand and Ethernet | SR-IOV |
VXLAN using IPoIB bridge | InfiniBand | Shared HCA |
