# Datadog
|
||||
|
||||
[Datadog](https://www.datadoghq.com/) is a hosted infrastructure monitoring platform.
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart adds the DataDog Agent to all nodes in your cluster via a DaemonSet.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Kubernetes 1.2+ with Beta APIs enabled
|
||||
|
||||
## Installing the Chart
|
||||
|
||||
To install the chart with the release name `my-release`, retrieve your DataDog API key from your [Agent Installation Instructions](https://app.datadoghq.com/account/settings#agent/kubernetes) and run:
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release \
|
||||
--set datadog.apiKey=YOUR-KEY-HERE stable/datadog
|
||||
```
|
||||
|
||||
After a few minutes, you should see hosts and metrics being reported in DataDog.
|
||||
|
||||
> **Tip**: List all releases using `helm list`
|
||||
|
||||
## 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 tables lists the configurable parameters of the Datadog chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
|-----------------------------|------------------------------------|-------------------------------------------|
|
||||
| `datadog.apiKey` | Your Datadog API key | `Nil` You must provide your own key |
|
||||
| `image.repository` | The image repository to pull from | `datadog/docker-dd-agent` |
|
||||
| `image.tag` | The image tag to pull | `latest` |
|
||||
| `imagePullPolicy` | Image pull policy | `IfNotPresent` |
|
||||
| `resources.requests.cpu` | CPU resource requests | 128M |
|
||||
| `resources.limits.cpu` | CPU resource limits | 512Mi |
|
||||
| `resources.requests.memory` | Memory resource requests | 100m |
|
||||
| `resources.limits.memory` | Memory resource limits | 256m |
|
||||
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release \
|
||||
--set datadog.apiKey=YOUR-KEY-HERE,datadog.logLevel=DEBUG \
|
||||
stable/datadog
|
||||
```
|
||||
|
||||
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
|
||||
|
||||
```bash
|
||||
$ helm install --name my-release -f values.yaml stable/datadog
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)

DataDog agents are spinning up on each node in your cluster. After a few
|
||||
minutes, you should see your agents starting in your event stream:
|
||||
|
||||
https://app.datadoghq.com/event/stream
|
||||
|
||||
No further action should be required.
