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.

/*
I was curious as to whether it was possible to make resources
created using CDK constructs work with raw CloudFormation
resources and vice versa.

This aws-cdk app demonstrates a VPC and an ELB that belongs to it
in different, dependant stacks, leveraging CFN outputs / imports,
and leveraging CDK's method of passing information from one
stack to another.

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
