# Dockerfile to build nghttp2 android binary
#
# $ sudo docker build -t nghttp2-android - < Dockerfile.android
#
# After successful build, android binaries are located under
# /root/build/nghttp2.  You can copy the binary using docker cp.  For
# example, to copy nghttpx binary to host file system location
# /path/to/dest, do this:
#
# $ sudo docker run -v /path/to/dest:/out nghttp2-android cp /root/build/nghttp2/src/nghttpx /out
