Accessing an EC2 via SSH using AWS SSM

ssh-config

## A basic set up of ~/.ssh/config in your local machine/client
## ssh i-0a1b2c3d4e5f6g7h8i9

Host i-*
  User ec2-user
  ProxyCommand bash -c "aws  ssm start-session --target %h --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"
  IdentityFile ~/.aws/test-mlozano001.pem


## In this case, it will search for a running instance that has the Tag:Name set to example-ssh-via-aws-ssm
## ssh example-ssh-via-aws-ssm

Host example-ssh-via-aws-ssm
  User ec2-user
  ProxyCommand bash -c "aws ssm start-session --target $(aws ec2 describe-instances --filters "Name=instance-state-name,Values=running" "Name=tag:Name,Values=example-ssh-via-aws-ssm" | jq -r '.Reservations[].Instances[].InstanceId') --document-name AWS-StartSSHSession --parameters 'portNumber=%p'"
