Setup Docker Desktop alternative on Mac OS X using Colima

docker-on-osx-using-colima.sh

# Prerequisites: Homebrew

# 1. Install the docker binary using homebrew
brew install docker

# 2. Install colima (the order is important since colima will automatically make configurations).
brew install colima

# 3. Start colima (start colima for the first time and let it download and
#    configure its dependencies; this will effectively setup, configure, and
#    boot a local, working kubernetes cluster.)
colima start --with-kubernetes

# 4. Happy running! You should now be able to run your images on this
#    cluster. The docker binary should already be configured at this
#    point, so try it out:
docker container run hello-world

# $ docker container run hello-world
#
# Unable to find image 'hello-world:latest' locally
# latest: Pulling from library/hello-world
# 2db29710123e: Pull complete
# Digest: sha256:507ecde44b8eb741278274653120c2bf793b174c06ff4eaa672b713b3263477b
# Status: Downloaded newer image for hello-world:latest
# 
# Hello from Docker!
# This message shows that your installation appears to be working correctly.
# 
# To generate this message, Docker took the following steps:
#  1. The Docker client contacted the Docker daemon.
#  2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
#     (amd64)
#  3. The Docker daemon created a new container from that image which runs the
#     executable that produces the output you are currently reading.
#  4. The Docker daemon streamed that output to the Docker client, which sent it
#     to your terminal.
# 
# To try something more ambitious, you can run an Ubuntu container with:
#  $ docker run -it ubuntu bash
# 
# Share images, automate workflows, and more with a free Docker ID:

--with-kubernetes is optional, it also works without k8s.
