# r2docker
# ========
#
# Requires 1GB of free disk space
#
# Build docker image with:
# $ docker build -t r2docker:latest .
#
# Run the docker image:
# $ docker images
# $ export DOCKER_IMAGE_ID=$(docker images --format '{{.ID}}' -f 'label=r2docker')
# $ docker run -ti --cap-drop=ALL r2docker:latest
#
# Once you quit the bash session get the container id with:
# $ docker ps -a | grep bash
#
# To get into that shell again just type:
# $ docker start -ai <containedid>
#
# To share those images:
# $ docker export <containerid> | xz > container.xz
# $ xz -d < container.xz | docker import -
#
#
# If you willing to debug a program within Docker, you should run it with CAP_SYS_PTRACE:
#
# $ docker run -it --cap-drop=ALL --cap-add=SYS_PTRACE r2docker:latest
# $ r2 -d /bin/true
#

# Using debian 10 as base image.
