What / Why

Deploy key is a SSH key set in your repo to grant client read-only (as well as r/w, if you want) access to your repo.

As the name says, its primary function is to be used in the deploy process, where only read access is needed. Therefore keep the repo safe from the attack, in case the server side is fallen.

How to

1. Generate a ssh key

PM2, EC2, and Github

Set Up Deploy Key on Remote Server

1. SSH into the target machine
2. Make a deploy_keys folder and change into it
   1. mkdir ~/.ssh/deploy_keys
   2. cd ~/.ssh/deploy_keys
3. Create a new key pair
4. ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
