# Dockerfile for providing buildozer
#
# Build with:
# docker build --tag=kivy/buildozer .
# 
# In order to give the container access to your current working directory
# it must be mounted using the --volume option.
# Run with (e.g. `buildozer --version`):
# docker run \
#   --volume "$HOME/.buildozer":/home/user/.buildozer \
#   --volume "$PWD":/home/user/hostcwd \
#   kivy/buildozer --version
#
# Or for interactive shell:
# docker run --interactive --tty --rm \
#   --volume "$HOME/.buildozer":/home/user/.buildozer \
#   --volume "$PWD":/home/user/hostcwd \
#   --entrypoint /bin/bash \
#   kivy/buildozer
#
# If you get a `PermissionError` on `/home/user/.buildozer/cache`,
# try updating the permissions from the host with:
# sudo chown $USER -R ~/.buildozer
# Or simply recreate the directory from the host with:
# rm -rf ~/.buildozer && mkdir ~/.buildozer
