One thing I cannot live without is the ease at which you can setup network interfaces on Linux. For example, with docker compose I can add this snippet: networks: vpcbr: driver: bridge ipam: config: - subnet: 10.20.0.0/16 gateway: 10.20.0.1 And, then each service can use something like this: networks: vpcbr: ipv4_address: 10.20.0.6 docker-compose up creates the network, and I can seamlessly access my services by a private IP address VPC. It's so powerful for testing real-world services where you need to have cookies created on the right IP address that is a different one from the auth server, etc. With OSX I have to use things like 127.0.0.1 and 127.0.0.2, but my docker compose file isn't aware of it, and it is very hacky. Linux networking supporting is phenomenal and so flexible.
