  • web define the name of the service as web
  • image: defines the image to pull
  • replicas defines the number of instances to run
  • limits limits each replica to use, at most, 10% of the CPU (across all cores), and 50MB of RAM.
  • restart_policy defines that a replica must restart on failure
  • ports map the port 80 on the host to web’s port 80. See Docker - Port
  • webnet defines a load-balanced network that shares the port 80 (Internally, the containers themselves publish to web’s port 80 at an ephemeral port.). The default settings is a load-balanced overlay network.
