My Beam/Dataflow pipeline involves some data processing which uses a Linux CLI tool (specifically, osmium-tool version >= 1.9.1) which is only available for some newer Ubuntu distros (cosmic or disco). I cannot find any documentation on the OS specs of Dataflow Workers, or if it is configurable.
Any help would be appreciated, thanks!
One of the goals of the Beam portability effort is to allow customizations such as this. Though it's still experimental at this point, you can follow the instructions at https://beam.apache.org/documentation/runtime/environments/ to completely configure the environment your user code runs in.
