What is Kubernetes. Kubernetes (commonly stylized as k8s) is an open-source system for automating deployment, scaling, and management of containerized applications. In this post i will shows you how to install Minikube, a tool that runs a single-node Kubernetes cluster in a virtual machine on your personal computer. The instructions used here are for the Mac. If you have a different operation system. Install Minikube Download Minikube and move it to your path. Starting up Kubernetes via Minikube in VirtualBox on Mac From the Mac terminal (iTerm2 or whatever you use) running minikube start should kick off the download of the minikube VirtualMachine image. If you would prefer to use another hypervisor (VMWare, kvm etc) you may need to specify the driver from this list. How to Install Kubernetes on Mac. This is a step-by-step guide to installing and running Kubernetes on your Mac so that you can develop applications locally. You will be guided through running and accessing a Kubernetes cluster on your local machine using the following tools: Homebrew; Docker for Mac; Minikube; virtualbox; kubectl.
Intro
This is a follow on to the previous writeup on Kubernetes with Minikube and shows how to quickly and easily get a Kubernetes cluster up and running using VirtualBox and Minikube. Military skirt (black) pubg.
The setup is very similar for all platforms, but this post is specifically focused on Mac, as I’m planning on using this as the basis for a more complex post on Jenkins & Kubernetes Pipelines (and that post is now posted, here!).
Installing required components
There are three main components required:
VirtualBox is a free and open source hypervisor. It is a light weight app that allows you to run Virtual Machines on most platforms (Mac, Windows, Linux). We will use it here to run the Minikube Virtual Machine.
Kubectl is a command line tool for controlling Kubernetes clusters, we install this on the host (Mac) and use it to control and interact with the Kubernetes cluster we will be running inside the Minikube VM.
Minikube is a tool that runs a single-node Kubernetes cluster in a virtual machine on your personal computer. We’re using this to provision our k8s cluster and will also take advantage of some of the developer friendly addons it offers.
Downloads and Instructions
Here are links to the required files and detailed instructions on setting each of these components up – I went for the ‘
brew install
‘ options but there are many alternatives in these links. The whole process is very simple and took about 10 minutes.VirtualBox: https://www.virtualbox.org/wiki/Downloads
simply download the Mac VirtualBox .dmg image file and install it
kubectl: https://kubernetes.io/docs/tasks/tools/install-kubectl/
brew install kubectl
Minikube: https://kubernetes.io/docs/tasks/tools/install-minikube/
brew install minikube
Starting up Kubernetes via Minikube in VirtualBox on Mac
From the Mac terminal (iTerm2 or whatever you use) running
minikube start
should kick off the download of the minikube VirtualMachine image.If you would prefer to use another hypervisor (VMWare, kvm etc) you may need to specify the driver from this list:
https://kubernetes.io/docs/setup/learning-environment/minikube/#specifying-the-vm-driver
https://kubernetes.io/docs/setup/learning-environment/minikube/#specifying-the-vm-driver
most popular hypervisors are well supported by Minikube.
Here’s what that looks like on my Mac – this may take a few minutes as it’s downloading a VM (if not already available locally), starting it up and configuring a Kubernetes Cluster inside it:
there’s quite a lot going on and not very much to see; you don’t even need to look at VirtualBox as it’s running ‘headless’, but if you open it up you can see the new running VM and its settings:
these values are all set to sensible defaults, but you may want to tweak things like memory or cpu allocations – running
minikube config -h
should help you see what to do, for example
minikube start --memory 1024
to change the allocated memory.
If you then take a look at the config file in
~/.minikube/config/config.js
you will see how your preferences – resource limits, addons etc – are persisted and managed there.Looking back at VirtualBox, if you click on “Show” or the running VM you can open that up to see the console for the Minikube VM:
to stop the vm simply do a
minikube stop
, or just type minikube
to see a list of args and options to manage the lifecycle, e.g. minikube delete
, status
, pause
, ssh
and so on.Minikube Addons
One of the handy features Minikube provides are its selection of easy to use addons. As explained in the official docs here you can see the list and current status of each addon by typing
minikube addons list
the storage-provisioner and default-storeageclass addons were automatically enabled on startup, but I usually like to add the metrics server and dashboard too, like so:
minikube addons enable metrics-server
minikube addons enable dashboard
I often use helm & tiller, efk, istio and the registry too – this feature save me a lot of time and messing about!
Accessing the Kubernetes Dashboard – all done!
Once that’s completed you can run
minikube dashboard
to open up the Kubernetes dashboard on your host. Minikube makes this all very easy; we didn’t have to forward ports, configure firewalls, consider ingress and egress, create RBAC roles, manage accounts/passwords/keys or set up DNS, or any of the many things you would normally want or have to consider to get to this point.
These features make Minikube a great choice for development work, where you don’t want to care about things like this as you would in a “for real” environment.
Your browser should open up the Kubernetes Dashboard, and you can click around and see the status of the many components that comprise your new Kubernetes cluster:

And then…
Next up I’ll be building on this setup by deploying a Jenkins instance inside the Kubernetes Cluster, then configuring that to use Kubernetes to build, manage and deploy applications on the same Kubernetes Cluster.
This is now covered in the next post, here:
Reading Time: 5minutesWhat Is Minikube?
Minikube is the name of a software program written in Go, which can build a local Kubernetes cluster on a single host. It uses a meager amount of resources to run a mini Kubernetes deployment. Minikube is mainly used for testing purposes using different scenarios or versions of Kubernetes
This is accomplished within a local environment, so a developer or administrator can review and adjust the needed variables. Since Minikube runs an instance of virtual box, installs Docker, and deploys the essential Kubernetes containers within that limited virtual space, it is not recommended for a production environment.
Linux CentOS installation
First, we need to check if our Linux system supports virtualization with the following command and verify that the output is non-empty and mentions “VMX“
Prerequisites
- This task should be initiated on a dedicated server as opposed to a VPS since a VPS is considered a virtualized service and will not support virtualization within that environment.
- Make sure we have kubectl installed before we start a Minikube installation.
- If we do not already have a hypervisor installed, install one of these now.
- KVM (which also uses QEMU)
- The Minikube option –vm-driver=none operates the Kubernetes components on a host and not within a VM. When using this driver, it will require both Docker and a Linux environment, but not a hypervisor.
- If we are using the none driver in Ubuntu/Debian, we should utilize the .deb package for Docker rather than the snap package, which does not work with Minikube.
- Before using the –vm-driver=none option, please consult the Minikube installation documentation for more information.
- Warning: Using the “none” VM driver may result in security problems and data loss issues.
Installing Minikube
There are several test packages for Minikube available. We can use the Linux (AMD64) packages from the Minikube’s releases pages noted on GitHub. In this instance, we will use the CentOS 7 Linux distribution package manager to install a proper version.
Install Minikube via Direct Download
First, we will download the appropriate package and then run this command.
Next, we will add the Minikube executable to our path using this command.
Installation on MacOS
First, we need to verify if virtualization is supported on our macOS. Run the following command in the terminal to check.
If we see “VMX” in the output, the VT-x feature will be enabled in our machine.
Prerequisites
If we do not have a hypervisor installed, we can use one of the following options.
- HyperKit
- VMware Fusion
Install Minikube
The quickest way to install Minikube on a macOS is by using Homebrew.
It can also be installed on our macOS by downloading the stand-alone binary.
Next, we should add the Minikube executable to our path. Adobe flash player version 10.1.0 download.
Windows installation
To verify if virtualization is installed on Windows 8and above, run the following command in our Windows terminal or via command prompt.
If we can see the following output, virtualization will be supported on Windows.
Uninstall Minikube Mac
- Hyper-V Requirements: VM Monitor Mode Extensions: Yes
- Virtualization Enabled In Firmware: Yes
- Second Level Address Translation: Yes
- Data Execution Prevention Available: Yes
Note: To enable Hyper-V on Windows 10, run the following command in the terminal or powershell (as administrator)
Prerequisites
Install Minikube On Mac
First, we should check to see if we have a hypervisor installed. If not, we can install one of these options.
- Hyper-V
- VirtualBox
Note: Hyper-V can run on these versions of Windows 10:
- Windows 10 Enterprise
- Windows 10 Professional
- Windows 10 Education
The Hyper-V role cannot be installed on Windows 10 Home.
Install Minikube using Chocolatey
The simplest method for the installation of Minikube on Windows is by using the Chocolatey install software. (Note: we should run this command as an administrator)
Once the Minikube installation completes, restart the CLI session. Once this finishes, Minikube will automatically be added to our path.
Confirm Installation & Start Cluster
To confirm successful installation of both a hypervisor and Minikube, we can run the following command to start up a local Kubernetes cluster:
Dirt 4 free download mac. Note: When setting the –vm-driver with the minikube start command, enter the name of the hypervisor installed in lowercase letters where <driver_name> is mentioned above. A full list of –vm-driver values is available in specifying the VM driver documentation.
Cluster Status
Once the minikube start command completes, run the command below to check the status of the cluster.
If our cluster is running, the output from minikube status should be similar to:
Once we verify that minikube is working with our selected hypervisor, we can begin using Minikube, or we can stop our cluster. To stop the cluster, run this command.
Clean up Local State
Next, if we installed Minikube, and run the minikube start command and it returned the error:
we need to clear to minikube’s local state using this command. 8x8 virtual office download mac.
Conclusion
Minikube is a useful tool for test multiple cluster options within a closed environment. It can also be used as a precursor to establish working parameters for a new Kubernetes cluster. The amount of options available for testing can be numerous which provides for a wide range of available situations.
