npm i -g @jcoreio/ec2-ssh
# Or
npx @jcoreio/ec2-ssh
Use at your own risk. Prompts you to select an EC2 instance, then SSHes into that instance, attempting to select the correct username automatically, and using the internal DNS hostname, and the identity file at ~/.ssh/<KeyName>.pem if it exists, where KeyName is the property of the EC2 instance in the aws-sdk response.
If you're not storing your identity files in that manner, you can add the following to your ~/.ssh/config:
Host *.compute.internal
User ec2-user
IdentityFile ~/.ssh/your-identity-file.pem
It will set the AWS_SDK_LOAD_CONFIG environment variable to load the default region from your ~/.aws/config.
See https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-region.html for other ways
of setting the default region.
