Hmm... I will check it. Does debian version also have same problem?

[mrdulin]

debian version:

  && apt-get update \

Recent docker image buid has no problem with gem install: https://hub.docker.com/r/fluent/fluentd/builds/b27nwmuueymnzgtfyi5ybwk/ So the problem seems out side of our docker image.
