+# apm-server
+
+[apm-server](https://www.elastic.co/guide/en/beats/apm-server/current/index.html)  is the server receives data from the Elastic APM agents and stores the data into a datastore like Elasticsearch.
+
+## Introduction
+
+This chart deploys apm-server agents to all the nodes in your cluster via a DaemonSet.
+
+By default this chart only ships a single output to a file on the local system.  Users should set config.output.file.enabled=false and configure their own outputs as [documented](https://www.elastic.co/guide/en/apm/get-started/current/install-and-run.html)
+
+## Prerequisites
+
+- Kubernetes 1.9+
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`, run:
+
+```bash
+$ helm install --name my-release stable/apm-server
+```
+
+After a few minutes, you should see service statuses being written to the configured output, which is a log file inside the apm-server container.
+
+> **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 table lists the configurable parameters of the apm-server chart and their default values.
+
+|             Parameter               |            Description             |                    Default                |
+|-------------------------------------|------------------------------------|-------------------------------------------|
+| `image.repository`                  | The image repository to pull from  | `docker.elastic.co/apm/apm-server`        |
+| `image.tag`                         | The image tag to pull              | `6.2.4`                                   |
+| `image.pullPolicy`                  | Image pull policy                  | `IfNotPresent`                            |
+| `rbac.create`                       | If true, create & use RBAC resources | `true`                                  |
+| `rbac.serviceAccount`               | existing ServiceAccount to use (ignored if rbac.create=true) | `default`       |
+| `config`                            | The content of the configuration file consumed by apm-server. See the [apm-server documentation](https://www.elastic.co/guide/en/beats/apm-server/current/apm-server-reference-yml.html) for full details |
+| `plugins`                           | List of beat plugins                                                           |
+| `extraVars`                         | A map of additional environment variables |                                    |
+| `extraVolumes`, `extraVolumeMounts` | Additional volumes and mounts, for example to provide other configuration files | |
+| `resources.requests.cpu`            | CPU resource requests              |                                           |
+| `resources.limits.cpu`              | CPU resource limits                |                                           |
+| `resources.requests.memory`         | Memory resource requests           |                                           |
+| `resources.limits.memory`           | Memory resource limits             |                                           |
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install --name my-release \
+    --set rbac.create=true \
+    stable/apm-server
+```
+
+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/apm-server
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
