How do I use SSH config to connect to my AWS EC2 instance?

You can simplify your SSH connections to AWS EC2 instances by using an SSH config file. Do you have a specific instance in mind?

Yes, I have an instance with the public IP 192.0.2.0.

Great! You can add an entry in your SSH config file like this:

Host my-ec2
    HostName 192.0.2.0
    User ec2-user
    IdentityFile ~/.ssh/my-key.pem

This allows you to connect using ssh my-ec2.

What if I have multiple instances?

You can add multiple entries in the same SSH config file, each with a unique Host name. Just follow the same format for each instance.

Can I specify different users for different instances?

Absolutely! Just set the User field to the appropriate username for each instance in your config.
