DockerForMac 17.12 Beta is the first release which includes both the orchestrators – Docker Swarm & Kubernetes under the same Docker platform.
Introduction Kubernetes (K8S) is an open-source workload scheduler with focus on containerized applications. We will be running a Kubernetes cluster on our local machine using the following tools:. Homebrew: a package manager for the Mac. Docker for Mac: Docker is used to create, manage, and run our containers. It lets us construct containers that will run in Kubernetes Pods.
Minikube: a Kubernetes-specific package that runs a Kubernetes cluster on our machine. That cluster has a single node and has some unique features that make it more suitable for local development. Minikube tells VirtualBox to run. Minikube can use other virtualization tools-not just VirtualBox-however these require extra configuration. VirtualBox: a generic tool for running virtual machines.

We can use it to run Ubuntu, Windows, etc. Inside our macOS operating system host. kubectl: a command line application that lets us interact with our Minikube Kubernetes cluster. It is a CLI-based tool mapped to API calls to manage all Kubernetes resources described in YAML files. It sends request to the Kubernetes API server running on the cluster to manage our Kubernetes environment. Kubectl is like any other application that runs on our Mac-it just makes HTTP requests to the Kubernetes API on the cluster. Installation Guide The only pre-requisite for this guide is that we should have installed.
Homebrew is a package manager for the Mac. We'll also need, which we can install after Homebrew by running brew tap caskroom/cask in our Terminal: $ brew tap caskroom/cask Updating Homebrew. Auto-updated Homebrew!

It lets us construct containers that will run in Kubernetes Pods. Install using Homebrew. Run brew cask install virtualbox in the Terminal. Terraform Install.
Press Command+Space and type Terminal and press enter/return key. Run in Terminal app: ruby -e '$(curl -fsSL /dev/null and press enter/return key. If the screen prompts us to enter a password, enter Mac's user password to continue. When we type the password, it won't be displayed on screen, but the system would accept it.
So just type our password and press ENTER/RETURN key. Then wait for the command to finish. Run: $ brew install terraform Downloading ######################################################################## 100.0% Pouring terraform-0.11.8.highsierra.bottle.tar.gz /usr/local/Cellar/terraform/0.11.8: 6 files, 88.9MB Done! We can now use terraform.
$ which terraform /usr/local/bin/terraform. Terraform Plan The plan will provide us an overview of planned changes, in this case we should see 2 resources (Pod + Service) being added: $ terraform plan Refreshing Terraform state in-memory prior to plan.

The refreshed state will be used to calculate this plan, but will not be persisted to local or remote state storage. An execution plan has been generated and is shown below. Sponsor Open Source development activities and free contents for everyone.
