A quick guide to deploying some Security Docker Containers.

Install

Grab a copy of Docker for your platform here: https://www.docker.com/community-edition#/download Follow the installation guide and tune the docker system to run with as much memory and CPU as you're willing to feed to it.

Docker Containers I find useful for general security tasks:

Local Debian instance: debian:latest

How to Reset Kafka Consumer Group Offset

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.

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