This is in response to issue #18900.
It shows how to set up an arangodb cluster with 3 agents, 2 coordinators and 3 db severs, using docker-compose. This
is not the way I would set up a cluster in production, but it is ok for testing the cluster functionality. I recommend
checking out the official documentation,
especially Using the ArangoDB Starter.
docker-compose.yml
version: '3.7'
