docker: docker start fails after creating daemon.json - docker

Question

I am trying to setup awslogs for docker.
The docs say to add this to daemon.json:
{
"log-driver": "awslogs",
"log-opts": {
"awslogs-region": "eu-central-1"
}
}
When I create on Ubuntu /etc/docker/daemon.json with the content above docker wont start again.

Can anybody explain this behaviour?

Not ever use it.
But from this: https://docs.docker.com/config/containers/logging/plugins/, it seems we need to install plugin for any new log driver, check it with docker plugin ls
Maybe it just available in amazon cloud environment, not available in local pc, just in case you did not notice that.
