docker-flatbuffers is Docker tooling for FlatBuffers. It also include C-language support using flatcc.

Rather than building your own FlatBuffers installation, you can run flatc or flatcc in a container and "bind mount" your input and output directories (see Usage As a Build Tool):

docker run -v /proj/src:/src -v /proj/dest:/dest neomantra/flatbuffers flatc --cpp --js --ruby -o /dest /src/monster.fbs

Images are availble in both gcc and clang variants, representing which toolchain was FlatBuffers was built from. The plain, undecorated tag name uses gcc. "master" branches are tagged with YYYYMMDD of the image build dates.

Specific FlatBuffers/flatc and flatcc releases are tagged with their version name. The flatc version is prefixed with v and the flatcc version is prefixed with cc.

• gcc, latest
• clang
• gcc-v1.8.0, v1.8.0
• clang-v1.8.0
• gcc-v1.8.0-cc0.5.1

The builds are managed by Travis-CI.

For best stability, pin your images to the full tag, for example neomantra/flatbuffers:gcc-v1.8.0-cc0.5.1.

You can COPY from this image into your own images using the following Dockerfile stanzas. Select the image, tag, and artifacts most appropriate for your project. The included files are listed in the Files In This Image section.

COPY --from=neomantra/flatbuffers /usr/local/bin/flatc /usr/local/bin/flatc
COPY --from=neomantra/flatbuffers /usr/local/include/flatbuffers /usr/local/include/flatbuffers
COPY --from=neomantra/flatbuffers /usr/local/lib/libflatbuffers.a /usr/local/lib/libflatbuffers.a
COPY --from=neomantra/flatbuffers /usr/local/lib/cmake/flatbuffers /usr/local/lib/cmake/flatbuffers


COPY --from=neomantra/flatbuffers /usr/local/bin/flatcc /usr/local/bin/flatcc
COPY --from=neomantra/flatbuffers /usr/local/include/flatcc /usr/local/include/flatcc
COPY --from=neomantra/flatbuffers /usr/local/lib/libflatcc.a /usr/local/lib/libflatccrt.a /usr/local/lib/

You can generate files on the host through volume bind mounts. The idea is that you mount a source directory into the container, invoke flatc on a schema in it, and write the output to a mounted destination.

Example:

# Input on host is in /my/src.
# Output written to /my/dest.
docker run -v /my/src:/src -v /my/dest:/dest neomantra/flatbuffers flatc --cpp --scoped-enums -o /dest /src/monster.fbs
