Attaching Fluentd Problem

Hi, i have trouble with attaching fluentd container on windows operating system with Linux Containers.
When i try to attach my running container as “docker attach fluentd” terminal hangs. When i try typing “docker exec -i -t fluentd /bin/bash” i got following error, “rpc error: code = 13 desc = invalid header field value “oci runtime error: exec failed: container_linux.go:247: starting container process caused “exec: \”/bin/bash\”: stat /bin/bash: no such file or directory”\n"". But i can successfully attach to elasticsearch container so i wouldnt think this is caused because of my windows host.
Any help would be appreciated.

My Dockerfile as follows

FROM fluent/fluentd:latest
MAINTAINER DenizArman
WORKDIR /home/fluent
ENV PATH /home/fluent/.gem/ruby/2.3.0/bin:$PATH
USER root
RUN apk --no-cache --update add sudo build-base ruby-dev &&
sudo -u fluent gem install fluent-plugin-elasticsearch &&
rm -rf /home/fluent/.gem/ruby/2.3.0/cache/.gem && sudo -u fluent gem sources -c &&
apk del sudo build-base ruby-dev && rm -rf /var/cache/apk/

USER fluent
CMD exec fluentd -c /fluentd/etc/$FLUENTD_CONF -p /fluentd/plugins $FLUENTD_OPT

My docker version and info output as follows.
