gokube is a tool that makes it easy developing day-to-day with Kubernetes on your laptop under Windows.

gokube downloads and installs many dependencies such as:

gokube deploys and configures Monocular for a better user experience! You will be able to deploy in one click useful helm charts for developing in your kubernetes cluster.

gokube is configured with a dedicated helm repository named miniapps which contains the following charts:

These charts are optimized in term of memory and cpu for minikube and very useful for developers.

Continuous Integration & Delivery

gokube is building and delivering under Travis and Github Actions.

How to upgrade gokube?

Windows

Download binary

$ gokube init

How to install gokube?

Windows

Requirements

VirtualBox or Hyper-V
VT-x/AMD-v virtualization must be enabled in BIOS
Internet connection on first run

Assumptions

You will use C:\gokube\bin to store executable files.

Set up your environment

gokube is aware of HTTP_PROXY, HTTPS_PROXY and NO_PROXY environment variables. When these variables are set, they are used to download the gokube dependencies and to configure docker daemon. You can define different proxy values for docker daemon in using –http-proxy, –https-proxy and –no-proxy init command flags

Set up your directory

You’ll need a place to store the gokube executable:

Open Windows Explorer.
Create a new folder: C:\gokube, assuming you want gokube on your C drive, although this can go anywhere.
Create a subfolder in the gokube folder: C:\gokube\bin

Download binary

The latest release for gokube can be download on the Releases page.
Copy executable file to: C:\gokube\bin
The gokube executable will be named as gokube-version-type+platform.arch.exe. Rename the executable to gokube.exe for ease of use.

Verify the executable

In your preferred CLI, at the prompt, type gokube and press the Enter key. You should see output that starts with:

$ gokube
gokube is a nice installer to provide an environment for developing day-to-day with kubernetes & helm on your laptop.

  pause       Pauses minikube. This command pauses minikube VM
  resume      Resumes minikube. This command resumes minikube VM
  start       Starts minikube. This command starts minikube
  stop        Stops minikube. This command stops minikube
  version     Shows version for gokube
