Installing Kubeval

Tagged versions of kubeval are built using GoReleaser and uploaded to GitHub. This means you should find tar.gz and .zip files under the release tab. These should contain a single kubeval binary for the platform in the filename (ie. windows, linux, darwin). Either execute that binary directly or place it on your path.


tar xf kubeval-linux-amd64.tar.gz
sudo cp kubeval /usr/local/bin


tar xf kubeval-darwin-amd64.tar.gz
sudo cp kubeval /usr/local/bin

For those using Homebrew you can use the kubeval tap:

brew tap instrumenta/instrumenta
brew install kubeval


Windows users can download the zip files from the releases page. For Scoop users you can install with:

scoop bucket add instrumenta
scoop install kubeval


kubeval is also published as a Docker image. This can be used as follows: follows:

$ docker run -it -v `pwd`/fixtures:/fixtures garethr/kubeval fixtures/*
