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-ENusing 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.
