⁠logging-operator

Logging operator for Kubernetes based on Fluentd and Fluent-bit. For more details please follow up with this post⁠.

⁠What is this operator for?

This operator helps you to pack together logging information with your applications. With the help of Custom Resource Definition you can describe the behaviour of your application within its charts. The operator does the rest.

⁠Motivation

The logging operator automates the deployment and configuration of a Kubernetes logging pipeline. Under the hood the operator configures a fluent-bit daemonset for collecting container logs from the node file system. Fluent-bit enriches the logs with Kubernetes metadata and transfers them to fluentd. Fluentd receives, filters and transfer logs to multiple outputs. The whole flow can be defined in a single custom resource. Your logs will always be transferred on authenticated and encrypted channels.

⁠Deploying with helm chart

The following steps set up an example configuration for sending nginx logs to S3.

⁠Add BanzaiCloud chart repository:

$ helm repo add banzaicloud-stable https://kubernetes-charts.banzaicloud.com
$ helm repo update

⁠Install logging-operator chart

$ helm install banzaicloud-stable/logging-operator

⁠Install FluentD, FluentBit CRs from chart

$ helm install banzaicloud-stable/logging-operator-fluent

⁠Deploying with Kubernetes Manifest

# Create all the CRDs used by the Operator
kubectl create -f deploy/crds/logging_v1alpha1_plugin_crd.yaml
kubectl create -f deploy/crds/logging_v1alpha1_fluentbit_crd.yaml
kubectl create -f deploy/crds/logging_v1alpha1_fluentd_crd.yaml

# If RBAC enabled create the required resources
kubectl create -f deploy/clusterrole.yaml
kubectl create -f deploy/clusterrole_binding.yaml
kubectl create -f deploy/service_account.yaml

# Create the Operator
kubectl create -f deploy/operator.yaml

# Create the fluent-bit daemonset by submiting a fluent-bit CR
kubectl create -f deploy/crds/logging_v1alpha1_fluentbit_cr.yaml

# Create the fluentd deployment by submitting a fluentd CR
kubectl create -f deploy/crds/logging_v1alpha1_fluentd_cr.yaml
