🎁 Resulting Solution

Docker architecture

Docker uses a client-server architecture. The Docker client talks to the Docker daemon, which does the heavy lifting of building, running, and distributing your Docker containers. The Docker client and daemon can run on the same system, or you can connect a Docker client to a remote Docker daemon. The Docker client and daemon communicate using a REST API, over UNIX sockets or a network interface. Another Docker client is Docker Compose, that lets you work with applications consisting of a set of containers.

Docker Daemon

The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A daemon can also communicate with other daemons to manage Docker services.

Minikube Docker Daemon

When using a container or VM driver (all drivers except none), you can reuse the Docker daemon inside minikube cluster. This means you don’t have to build on your host machine and push the image into a docker registry. You can just build inside the same docker daemon as minikube which speeds up local experiments.

#this will tell Docker Client to use Docker Daemon inside Minikube
& minikube -p agones docker-env | Invoke-Expression

#this build will be executed by Minikube's Docker Daemon
docker build -t unity-headless .
