Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

1. List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

2. Reset the consumer offset for a topic (preview)

DEPRECATED, use https://github.com/vincepare/docker-backup instead

Finds the readwrite layer (top-most layer) and filesystem root of a docker container.

Accessing the readwrite layer from the docker host can be useful to backup ephemeral container data, while finding the filesystem root allow to browse a container directory structure without having to login into.

Please not that this could only work with union filesystem based storage driver like AUFS and Overlay2. Currently, only AUFS is supported, feel free to contribute to add Overlay2 support.
