I am trying docker examples and wanted to set the DOCKER_OPTS, but not able to find /etc/default/docker on amazon linux machine. Where to look for it?

Adding DOCKER_OPTS to /etc/sysconfig/docker will not work in Amazon Linux 2.
You will see this when watching the logs.
journalctl -u docker.service

So you will need to add the config to /etc/docker/daemon.json.
