# Quickstart Guide
|
|
|
|
This guide covers how you can quickly get started using Helm.
|
|
|
|
## Prerequisites
|
|
|
|
- You must have Kubernetes installed, and have a local configured copy
|
|
of `kubectl`.
|
|
|
|
## Install Helm
|
|
|
|
Download a binary release of the Helm client from
|
|
[the official project page](https://github.com/kubernetes/helm/releases).
|
|
|
|
Alternately, you can clone the GitHub project and build your own
|
|
client from source. The quickest route to installing from source is to
|
|
run `make bootstrap build`, and then use `bin/helm`.
|
|
|
|
## Initialize Helm and Install Tiller
|
|
|
|
Once you have Helm ready, you can initialize the local CLI and also
|
|
install Tiller into your Kubernetes cluster in one step:
|
|
|
|
```console
|
|
$ helm init
|
|
```
|
|
|
|
## Install an Example Chart
|
|
|
|
To install a chart, you can run the `helm install` command.
|
|
Let's use an example chart from this repository.
|
|
Make sure you are in the root directory of this repo.
|
|
|
|
|
|
```console
|
|
$ helm install docs/examples/alpine
|
|
Released smiling-penguin
|
|
```
|
|
|
|
In the example above, the `alpine` chart was released, and the name of
|
|
our new release is `smiling-penguin`. You can view the details of the chart we just
|
|
installed by taking a look at the nginx chart in
|
|
[docs/examples/alpine/Chart.yaml](examples/alpine/Chart.yaml).
|
|
|
|
## Change a Default Chart Value
|
|
|
|
A nice feature of helm is the ability to change certain values of the package for the install.
|
|
Let's install the `nginx` example from this repository but change the `replicaCount` to 7.
|
|
|
|
```console
|
|
$ helm install --set replicaCount=7 docs/examples/nginx
|
|
happy-panda
|
|
```
|
|
|
|
You can view the chart for this example in
|
|
[docs/examples/nginx/Chart.yaml](examples/nginx/Chart.yaml) and the default values in
|
|
[docs/examples/nginx/values.yaml](examples/nginx/values.yaml).
|
|
|
|
## Learn About The Release
|
|
|
|
To find out about our release, run `helm status`:
|
|
|
|
```console
|
|
$ helm status smiling-penguin
|
|
Status: DEPLOYED
|
|
```
|
|
|
|
## Uninstall a Release
|
|
|
|
To uninstall a release, use the `helm delete` command:
|
|
|
|
```console
|
|
$ helm delete smiling-penguin
|
|
Removed smiling-penguin
|
|
```
|
|
|
|
This will uninstall `smiling-penguin` from Kubernetes, but you will
|
|
still be able to request information about that release:
|
|
|
|
```console
|
|
$ helm status smiling-penguin
|
|
Status: DELETED
|
|
```
|
|
|
|
## Reading the Help Text
|
|
|
|
To learn more about the available Helm commands, use `helm help` or type
|
|
a command followed by the `-h` flag:
|
|
|
|
```console
|
|
$ helm get -h
|
|
```
