IMPORTANT - create WITH tags:

$ aws ec2 run-instances --image-id ami-0022f774911c1d690 --security-group-ids sg-0b8cf89d293b7adfc --instance-type t3.medium --key-name sm-key --count 1 --no-paginate --tag-specifications 'ResourceType=instance,Tags=[{Key=usage,Value=guide-examples}]' 'ResourceType=volume,Tags=[{Key=usage,Value=guide-examples}]'

IMPORTANT - query with tags in CLI

$ aws ec2 describe-instances --query 'Reservations[].Instances[].InstanceId' --filters "Name=tag:usage,Values=guide-examples" --output text
