Just a FYI, that I forked this docker image and updated the version. https://github.com/kimmobrunfeldt/docker-backblaze-b2

Beware that I also changed a bit how the entrypoint works, so you need to use the env variables and prefix all commands with b2.

@kimmobrunfeldt I like your idea of needing to prefix b2. I also added i my pull #3 to not authorize if one does version or help.

Now there is an official image as explained at https://www.backblaze.com/docs/cloud-storage-use-the-b2-sync-command-with-the-cli . Can be used as sudo docker run --rm -v $PWD:/root -it --entrypoint bash backblazeit/b2:latest and then b2 commands.
