# Sample Dockerfile to install UCX in a Unbuntu 18.04 image with RDMA support.
#
# The parameters are: 
#   - RDMA_CORE_VERSION: Set to 32.1 to match the rdma-core line in the latest 
#                        released MLNX_OFED 5.x driver
#   - CUDA_VER: 11.2.2 to pick up the latest 11.2 CUDA base layer
#   - UCX_VER and UCX_CUDA_VER: these are used to pick a package matching a specific UCX version and
#                               CUDA runtime from the UCX github repo.
#                               See: https://github.com/openucx/ucx/releases/
#
# The Dockerfile first fetches and builds `rdma-core` to satisfy requirements for
# the ucx-ib and ucx-rdma RPMs.
