Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Large Scale WebRTC Broadcast

Large Scale WebRTC Broadcast

The Problem

WebRTC is a protocol that has been standardized in recent years among major browsers like Chrome, Firefox, Opera and the Android Browsers. Plugins/Native Implementations are available on IE/Edge/Safari and iOS/Android basically providing a relatively global protocol for real time media streams. However WebRTC is a P2P protocol which means that if a user wishes to broadcast his/her video to multiple users he/she needs to individually send that broadcast to each participant. This works on a small scale, but degrades quickly on a large scale due to bandwidth deterioration.

The Solution

One possible solution is to let the user stream his/her media to a server and the server in turn splits the media streams to the subscribers. There are two technical ways to do this. A Selective Forwarding Unit (SFU) which simply forwards streams, and a Multipoint Control Unit (MCU) which essentially does the same thing but lowers bandwidth usage by packaging streams together.

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)
