This file / package should be installed on the EC2 instance through which you want to tunnel traffic to its VPC.
It is useless on its own, it should be used with [ssm-tunnel] from aws-ssm-tools.
The agent requires Python 2.7 or newer and has no external dependencies. It should work out of the box on any recently installed Amazon Linux 2 instance.
The easiest way to install the agent is from PyPI repository:
sudo pip install aws-ssm-tunnel-agent
If pip command is not available you can download it straight from GitHub:
sudo curl -o /usr/local/bin/ssm-tunnel-agent https://raw.githubusercontent.com/mludvig/aws-ssm-tools/master/ssm-tunnel-agent
sudo chmod +x /usr/local/bin/ssm-tunnel-agent
Hint: these commands can be copy & pasted to an ec2-session command prompt :)
