Using Project Dockerfiles

Building/Running User Image

user-image/start_user_container can be used to automatically build and run the base and user dockerfiles. It must be run from the root of the project repo. It does the following for you:

  • Builds both of the the base dockerfiles(clang and/or gcc).
  • Builds the user dockerfile, based on both of the newly built base images.
  • Starts a container from the newly built user images with the following properties:
    • It's named with your host username so it's easy to manage later.
    • It has a user whose name and ID match your host user.
    • That user has git configured with the same git username and email as the host user.
    • The host git repo is mounted in the /data folder.
    • The correct arguments are passed in to give the container access to the host GPUs.

The defaults are good for most cases. For example, the following will checkout the repo and build/run the gcc and clang dockerfiles.

$ git checkout git@github.com:ROCm/rocRoller.git rocroller
$ cd rocroller
$ ./docker/user-image/start_user_container
...
Enter these containers with the following commands:
docker exec -ti -u USER USER_dev_clang bash
docker exec -ti -u USER USER_dev_gcc bash

After running the script, there will be containers running that you can enter and exit:

$ docker ps -a
CONTAINER ID   IMAGE                          COMMAND                  CREATED             STATUS                        PORTS     NAMES
b6d83ba92ff3   roller-gcc-user:latest     "/opt/user-entrypoint"   20 minutes ago      Up <1 minutes                           USER_dev_gcc
5e502b7b5cab   roller-clang-user:latest   "/opt/user-entrypoint"   21 minutes ago      Up <1 minutes                           USER_dev_clang
$ docker exec -ti -u USER USER_dev_clang bash
$ ls /data
CMakeLists.txt  CppCheckSuppressions.txt  GPUArchitectureGenerator  README.md  build_clang  build_gcc  dependencies  docker  docs  lib  scripts  test
$ exit
$ docker exec -ti -u USER USER_dev_gcc bash
$ ls /data
CMakeLists.txt  CppCheckSuppressions.txt  GPUArchitectureGenerator  README.md  build_clang  build_gcc  dependencies  docker  docs  lib  scripts  test
$ exit

Note: The containers started by the script will exist until they are manually removed. To manually remove a container you can use docker rm -f <container name>.

The following is a more complicated example that uses the following options:

  • --privileged: runs the container in prvileged mode.
  • --delete_existing_container: will remove any already launched containers and replace them with newly launched ones.
  • --versions clang: instructs the script to only build and run the clang version of the dockerfile.
  • --user_build_extra_args="--no-cache": passes the extra argument --no-cache to docker build when building the user image.
  • --volumes="/home/USER:/host_home": adds the extra volume mapping to the docker run command.
$ ./docker/user-image/start_user_container --privileged \
                                           --delete_existing_container \
                                           --versions clang \
                                           --user_build_extra_args="--no-cache" \
                                           --volumes="/home/USER:/host_home"

For a full list of options see ./docker/user-image/start_user_container -h.
