####
# A Docker container for running zmap
#
# To build, beware of caching and:
#
#   * If you wish to build current main
#
#        docker build -t zmap .
#
#   * If you wish to build a specific commit, git checkout to that specific commit before building
#
# To run CI pre-built images, use:
#
#     docker run -it --rm --net=host ghcr.io/zmap/zmap <zmap args>
