How to find out name of current instance from command-line?

Is there an easy way to determine (ie, through boto3 or aws-cli), which instance I'm on, from an SSH session in that instance?

When you say which instance, do you mean the instance id or instance name or instance private ip or instance public ip?

Query the instance metadata server.

curl 169.254.169.254/latest/meta-data/instance-id

If you want the instance tags:

aws ec2 describe-tags --filters "Name=resource-id,Values=instance_id"

or

aws ec2 describe-tags --filters "Name=resource-id,Values=`curl
169.254.169.254/latest/meta-data/instance-id`"

For instance's private IP:

curl 169.254.169.254/latest/meta-data/local-ipv4

For all available values:

curl 169.254.169.254/latest/meta-data/
