"Docker, a gajillion dollar company" - LOL they barely get along.
While I love Docker as a dev tool putting all strings into your hand to juggle customer environments, I fail to see the use case of Docker on Macs and Windows, which I'm understanding what Docker desktop is about. After all, docker images are about saving the resources/memory for a full VM and using Linux kernel-level compartments instead.
When you're developing in a container you can guaranty that the environment is the same on your PC or in the cloud.
Also, the same argument you had for shared resources in Linux, when you're running Linux on a VM locally on your desktop because you want linux tools or applications, then you want as much memory management as possible.
I develop on my Windows machine and I use Docker for testing. We have a a microservices architecture in production and using Docker is easier and less messy to run locally parts of our infrastructure such as Postgres, Redis, Consul, Nats and some of the needed microservices instead of using VMs.
