|
|
A chart for a cAdvisor deployment
|
|
|
|

|
|
|
|
## TL;DR;
|
|
|
|
```bash
|
|
$ helm install ckotzbauer/cadvisor
|
|
```
|
|
|
|
## Introduction
|
|
|
|
This chart creates a daemonset on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
|
|
|
|
## Prerequisites
|
|
|
|
- Kubernetes 1.10+
|
|
|
|
## Installing the Chart
|
|
|
|
To install the chart with the release name `my-release`:
|
|
|
|
```bash
|
|
$ helm install --name my-release ckotzbauer/cadvisor
|
|
```
|
|
|
|
The command deploys cAdvisor on the Kubernetes cluster using the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
|
|
|
|
## Upgrading from v1.x to v2.x
|
|
|
|
- `metrics.relabelings` was renamed to `metrics.metricsRelabelings` to match the ServiceMonitor CRD naming
|
|
|
|
## Uninstalling the Chart
|
|
|
|
To uninstall/delete the `my-release` deployment:
|
|
|
|
```bash
|
|
$ helm delete my-release
|
|
```
|
|
The command removes all the Kubernetes components associated with the chart and deletes the release.
|
|
|
|
## Configuration
|
|
|
|
The following table lists the configurable parameters of the cAdvisor chart and their default values.

|
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
|
|
|
```bash
|
|
$ helm install --name my-release \
|
|
--set key_1=value_1,key_2=value_2 \
|
|
ckotzbauer/cadvisor
|
|
```
|
|
|
|
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
|
|
|
```bash
|
|
# example for staging
|
|
$ helm install --name my-release -f values.yaml ckotzbauer/cadvisor
|
|
```
|
|
|
|
> **Tip**: You can use the default [values.yaml](values.yaml)

## Centos, Fedora and RHEL
|
|
You may need to run the container with additional configuration. Please see [this article](https://github.com/google/cadvisor/blob/master/docs/running.md#centos-fedora-and-rhel). |
