You do not want to write all the Kubernetes manifests by hand. Instead, you would like to be able to search for a package in a repository and download and install it with a command-line interface.
Use Helm. Helm is the Kubernetes package manager; it defines a Kubernetes package as a set of manifests and some metadata. The manifests are actually templates. The values in the templates are filled when the package is instantiated by Helm. A Helm package is called a chart.
Helm has a client-side CLI called
helm and a server called
tiller. You interact with charts using
tiller runs within your Kubernetes cluster as a regular Kubernetes deployment.
You can build Helm from source or download it from the GitHub release page, extract the archive, and move the
helm binary into your
$PATH. For example, on macOS, for the v2.7.2 release of Helm, do this:
$ wget https://storage.googleapis.com/kubernetes-helm/ \ helm-v2.7.2-darwin-amd64.tar.gz $ tar -xvf helm-v2.7.2-darwin-amd64.tar.gz $ sudo mv darwin-amd64/64 /usr/local/bin $ helm version
Now that the
helm command is in your
$PATH, you can use it to start the server-side component,
tiller, on your Kubernetes cluster. Here we use Minikube as an example:
$ kubectl get nodes ...
