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,latestclanggcc-v1.8.0,v1.8.0clang-v1.8.0gcc-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.

COPY --from=neomantra/flatbuffers /usr/local/include/flatbuffers /usr/local/include/flatbuffers

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

The Docker image build can be customized using the following build arguments. They are activated by applying --build-arg <arg>=<value> to your docker build run.
| Arg | Default | Description |
|---|---|---|
| FLATBUFFERS_IMAGE_BASE | debian | Docker image to use as a base image |
| FLATBUFFERS_IMAGE_TAG | bullseye-slim | Docker image tag to use as a base image |
| FLATBUFFERS_ARCHIVE_BASE_URL | https://github.com/google/flatbuffers/archive | URL to download the flatbuffers archive from |
| FLATBUFFERS_ARCHIVE_TAG | master | FlatBuffers tag to download |
| FLATBUFFERS_BUILD_TYPE | Release | CMake build type (e.g. Release, Debug) |
| FLATBUFFERS_USE_CLANG | false | Set to exactly "true" to build with clang instead of gcc |
| FLATCC_ARCHIVE_BASE_URL | https://github.com/dvidelabs/flatcc/archive/ | URL to download the flatcc archive from |
| FLATCC_ARCHIVE_TAG | master | flatcc tag to download |
