# Fluentd Helm Chart
|
||||
|
||||
[Fluentd](https://www.fluentd.org/) is an open source data collector for unified logging layer. Fluentd allows you to unify data collection and consumption for a better use and understanding of data.
|
||||
|
||||
## Installation
|
||||
|
||||
To add the `fluent` helm repo, run:
|
||||
|
||||
```sh
|
||||
helm repo add fluent https://fluent.github.io/helm-charts
|
||||
helm repo update
|
||||
```
|
||||
|
||||
To install a release named `fluentd`, run:
|
||||
|
||||
```sh
|
||||
helm install fluentd fluent/fluentd
|
||||
```
|
||||
## Upgrading
|
||||
|
||||
### To 0.4.0
|
||||
|
||||
Although the services will deploy and generally work, version 0.4.0 introduces some changes that are considered _breaking changes_. To upgrade, you should do the following to avoid any potential conflicts or problems:
|
||||
|
||||
- Add the `mountVarLogDirectory` and `mountDockerContainersDirectory` values and set them to the values you need; to follow the previous setup where these were mounted by default, set the values to `true`, e.g. `mountVarLogDirectory: true`
|
||||
- If you have the `varlog` mount point defined and enabled under both `volumes` and `volumeMounts`, set `mountVarLogDirectory` to true
|
||||
- If you have the `varlibdockercontainers` mount point defined and enabled under both `volumes` and `volumeMounts`, set `mountDockerContainersDirectory` to true
|
||||
- Remove the previous default volume and volume mount definitions - `etcfluentd-main`, `etcfluentd-config`, `varlog`, and `varlibdockercontainers`
|
||||
- Remove the `FLUENTD_CONF` entry from the `env:` list
|
||||
|
||||
## Chart Values
|
||||
|
||||
```sh
|
||||
helm show values fluent/fluentd
|
||||
```
|
||||
|
||||
## Value Details
|
||||
|
||||
### default-volumes
|
||||
|
||||
The default configurations bellow are required for the fluentd pod to be able to read the hosts container logs. The second section is responsible for allowing the user to load the "extra" configMaps either defined by the `fileConfigs` contained objects or, in addition, loaded externally and indicated by `configMapConfigs`.
|
||||
|
||||
```yaml
|
||||
- name: varlog
|
||||
hostPath:
|
||||
path: /var/log
|
||||
- name: varlibdockercontainers
|
||||
hostPath:
|
||||
path: /var/lib/docker/containers
|
||||
---
|
||||
- name: etcfluentd-main
|
||||
configMap:
|
||||
name: fluentd-main
|
||||
defaultMode: 0777
|
||||
- name: etcfluentd-config
|
||||
configMap:
|
||||
name: fluentd-config
|
||||
defaultMode: 0777
|
||||
```
|
||||
|
||||
### default-volumeMounts
|
||||
|
||||
The default configurations bellow are required for the fluentd pod to be able to read the hosts container logs. They should not be removed unless for some reason your container logs are accessible through a different path
|
||||
|
||||
```yaml
|
||||
- name: varlog
|
||||
mountPath: /var/log
|
||||
- name: varlibdockercontainers
|
||||
mountPath: /var/lib/docker/containers
|
||||
readOnly: true
|
||||
```
|
||||
|
||||
The section bellow is responsible for allowing the user to load the "extra" configMaps either defined by the `fileConfigs` contained objects or otherwise load externally and indicated by `configMapConfigs`.
|
||||
|
||||
```yaml
|
||||
- name: etcfluentd-main
|
||||
mountPath: /etc/fluent
|
||||
- name: etcfluentd-config
|
||||
mountPath: /etc/fluent/config.d/
|
||||
```
|
||||
|
||||
### default-fluentdConfig
|
||||
|
||||
The `fileConfigs` section is organized by sources -> filters -> destinations. Flow control must be configured using fluentd routing with tags or labels to guarantee that the configurations are executed as intended. Alternatively you can use numeration on your files to control the configurations loading order.

|

|
||||
## Backwards Compatibility - v0.1.x
|
||||
|
||||
The old fluentd chart used the ENV variables and the default fluentd container definitions to set-up automatically many aspects of fluentd. It is still possible to trigger this behaviour by removing this charts current `.Values.env` configuration and replace by:
|
||||
|
||||
```yaml
|
||||
env:
|
||||
- name: FLUENT_ELASTICSEARCH_HOST
|
||||
value: "elasticsearch-master"
|
||||
- name: FLUENT_ELASTICSEARCH_PORT
|
||||
value: "9200"
|
||||
```
