Kubesheet

Kubesheet is an kubernetes cli wrapper with a focus to explore the kubernetes REST API's leveraging the go libraries available along with golang and cobra package.

Install the cobra library:

 go get -u github.com/spf13/cobra/cobra

Create the CLI skeleton

cobra init --package-name kubesheet

It will initialize the kubesheet project with cobra as the library.

Set up minikube

Execute below commands inside kubesheet folder. Minikube must be installed as it'll need to check for default server to connect to.

 go install

In powershell as admin:
New-Item -Path 'c:\' -Name 'minikube' -ItemType Directory -Force
Invoke-WebRequest -OutFile 'c:\minikube\minikube.exe' -Uri 'https://github.com/kubernetes/minikube/releases/latest/download/minikube-windows-amd64.exe' -UseBasicParsing


Next add your binary to the path:

$oldPath = [Environment]::GetEnvironmentVariable('Path', [EnvironmentVariableTarget]::Machine)
if ($oldPath.Split(';') -inotcontains 'C:\minikube'){ `
  [Environment]::SetEnvironmentVariable('Path', $('{0};C:\minikube' -f $oldPath), [EnvironmentVariableTarget]::Machine) `
}

Docker

docker build -o kubesheet main.go 

docker pull kubesheet:latest

docker run kubesheet

Install package dependencies

go get https://github.com/DanielPickens/kubesheet.git

Cloning

 git clone https://github.com/DanielPickens/kubesheet.git 

Root and Sub Command

kubesheet is a root command and dig is a sub command to that. For this case, we could have a set of subcommands such as below:

 kubesheet dig1

will list out all the pods

 kubesheet dig2

This will list out all the deployments…vice versa. So, to extend our existing skeleton to have subcommand, just execute the below:

cobra add dig

Connect to cluster and config root.go

a. Connect to a cluster using “kubeconfig” REST API call ''' → root.go ''' The changes required in “step a” needs to be implemented in the root.go wherein you just need to provide the path of your own config file.

Locate to the config in root.go and change the config file path above when required. In root.go you'll just need to have above function which takes care of connecting to the minkube cluster using a REST call.
b. Once connected, you would simply need to make a call to rest API to:

“list pods available” → dig.go

Go to dig.go and follow the changes required to make a call to the REST API to list all the pods available in the cluster.

Testing

go install

kubesheet dig
