Tcpdump

Tcpdump is a commandline tool that is used to dump traffic on a network. This tool comes in hand when you want to analyse network captures within the command line. Basically it can do most of the wireshark job.

NOTE This guide might not be complete it just serve as a reference to me.

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

knowledge dump on container runtimes

KataContainers
- image coupled with kernel 
- light vm layer
- can run in nested virturalization environments if hardware supports and you can enable it in bios (ex. only bare metal EC2 instances, limits many cloud providers)
- slower startup time
- OCI compliant
- previously known as ClearContainers by Intel
