# CoScale
|
||||
|
||||
[CoScale](https://www.coscale.com/) offers full-stack monitoring for containers and microservices.
|
||||
|
||||
## Introduction
|
||||
|
||||
This chart adds the CoScale 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 CoScale details from your [Agent page](https://app.coscale.com/) and run:
|
||||
|
||||
```bash
|
||||
$ helm install \
|
||||
--name my-release \
|
||||
--set coscale.appId=YOUR-APP-ID,coscale.accessToken=YOUR-ACCESS-TOKEN,coscale.templateId=YOUR-TEMPLATE-ID \
|
||||
stable/coscale
|
||||
```
|
||||
|
||||
After a few minutes, you should see hosts and containers appearing in the CoScale UI.
|
||||
|
||||
> **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 CoScale chart and their default values.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
|-----------------------------|------------------------------------|-------------------------------------------|
|
||||
| `coscale.appId` | Your CoScale Application Id | `Nil` You must provide your own |
|
||||
| `coscale.accessToken` | Your CoScale Access Token | `Nil` You must provide your own |
|
||||
| `coscale.templateId` | Your CoScale Agent Template Id | `Nil` You must provide your own |
|
||||
| `image.repository` | The image repository to pull from | `coscale/coscale-agent` |
|
||||
| `image.tag` | The image tag to pull | `3.10.11` |
|
||||
| `image.pullPolicy` | The Image pull policy | `IfNotPresent` |
|
||||
|
||||
|
||||
Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`.
|
||||
|
||||
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/coscale
|
||||
```
|
||||
|
||||
> **Tip**: You can use the default [values.yaml](values.yaml)

CoScale agents are spinning up on each node in your cluster. After a few
|
||||
seconds, you should see your hosts and hosts appearing in the CoScale UI:
|
