Running Docker on MacOS

Terminology:

• Docker Engine
  • open-source
  • container lifecycle, isolation of resources
  • runs on Linux only (or a Linux virtual machine)
• Docker CLI
  • open-source
  • interacts with engine using docker command
• Docker Desktop
  • closed-source
  • manages virtualization required for Docker Engine on Windows and macOS

Running the Docker Engine on a Linux VM without Docker Desktop

We will use the Docker engine (daemon) that comes with minikube and hyperkit for virtualization:

brew install hyperkit   # virtualization
brew install minikube   # K8s cluster, with Docker daemon
brew install docker     # Docker CLI

We can then start the minikube cluster an connect it with the Docker CLI:

minikube start
eval $(minikube docker-env)
