This ensures your deployment does not change automatically if the same tag is updated with a different image. + +Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist. + +### Production configuration and horizontal scaling + +This chart includes a `values-production.yaml` file where you can find some parameters oriented to production configuration in comparison to the regular `values.yaml`. You can use this file instead of the default one. + +- Number of aggregator nodes: +```diff +- aggregator.replicaCount: 1 ++ aggregator.replicaCount: 2 +``` + +- Enable prometheus to access fluentd metrics endpoint: +```diff +- metrics.enabled: false ++ metrics.enabled: true +``` + +To horizontally scale this chart once it has been deployed, you can upgrade the deployment using a new value for the `aggregator.replicaCount` parameter. + +### Forwarding the logs to another service + +By default, the aggregators in this chart will send the processed logs to the standard output. However, a common practice is to send them to another service, like Elasticsearch, instead. This can be achieved with this Helm Chart by mounting your own configuration files. For example: + +**configmap.yaml** + +```yaml +apiVersion: v1 +kind: ConfigMap +metadata: + name: elasticsearch-output +data: + fluentd.conf: | + # Prometheus Exporter Plugin + # input plugin that exports metrics + <source> + @type prometheus + port {{ .Values.metrics.service.port }} + </source> + + # input plugin that collects metrics from MonitorAgent + <source> + @type prometheus_monitor + <labels> + host ${hostname} + </labels> + </source> + + # input plugin that collects metrics for output plugin + <source> + @type prometheus_output_monitor + <labels> + host ${hostname} + </labels> + </source> + {{- end }} + + # Ignore fluentd own events + <match fluent.**> + @type null + </match> + + # TCP input to receive logs from the forwarders + <source> + @type forward + bind 0.0.0.0 + port {{ .Values.aggregator.port }} + </source> + + # HTTP input for the liveness and readiness probes + <source> + @type http + bind 0.0.0.0 + port 9880 + </source> + + # Throw the healthcheck to the standard output instead of forwarding it + <match fluentd.healthcheck> + @type stdout + </match> + + # Send the logs to the standard output + <match **> + @type elasticsearch + include_tag_key true + host "#{ENV['ELASTICSEARCH_HOST']}" + port "#{ENV['ELASTICSEARCH_PORT']}" + logstash_format true + + <buffer> + @type file + path /opt/bitnami/fluentd/logs/buffers/logs.buffer + flush_thread_count 2 + flush_interval 5s + </buffer> + </match> +``` + +As an example, using the above configmap, you should specify the required parameters when upgrading or installing the chart: + +```console +aggregator.configMap=elasticsearch-output +aggregator.extraEnv[0].name=ELASTICSEARCH_HOST +aggregator.extraEnv[0].value=your-ip-here +aggregator.extraEnv[1].name=ELASTICSEARCH_PORT +aggregator.extraEnv[1].value=your-port-here +``` + +### Notable changes + +## 1.0.0 + +In this version of the chart the Fluentd forwarder daemon system user will be root by default. This is done to ensure that mounted host paths are readable by the forwarder. For more context, check this [support case](https://github.com/bitnami/charts/issues/1905). + +No issues are expected in the upgrade process. However, please ensure that you add extra security measures in your cluster as you will be running root containers. If you want the daemon to be run as a user different from root, you can change the `forwarder.daemonUser` and `forwarder.daemonGroup` values. In this case make sure that the user you choose has sufficient permissions to read log files under `/var/lib/docker/containers` directory. diff --git a/deployments/helm/v2/emco/fluentd/templates/NOTES.txt b/deployments/helm/v2/emco/fluentd/templates/NOTES.txt new file mode 100644 index 00000000..eea7a2aa --- /dev/null +++ b/deployments/helm/v2/emco/fluentd/templates/NOTES.txt @@ -0,0 +1,30 @@ +** Please be patient while the chart is being deployed ** + + To verify that Fluentd has started, run: + + kubectl get all -l "app.kubernetes.io/name={{ include "fluentd.name" . }},app.kubernetes.io/instance={{ .Release.Name }}" +{{ if and .Values.aggregator.enabled .Values.forwarder.enabled (not .Values.aggregator.configMap) }} + Logs are captured on each node by the forwarder pods and then sent to the aggregator pods.
