kubectl build

(formerly known as kubectl-kaniko)

Kubectl build mimics the kaniko executor, but performs building on your Kubernetes cluster side.
This allows you to simply build your local dockerfiles remotely without leaving your cozy environment.

Installation

using krew:

kubectl krew index add kvaps https://github.com/kvaps/krew-index
kubectl krew install kvaps/build

or using curl:

curl -LO https://github.com/kvaps/kubectl-build/raw/master/kubectl-build
chmod +x ./kubectl-build
sudo mv ./kubectl-build /usr/local/bin/kubectl-build

Usage

kubectl build [args]

Examples
