Logging operator for Kubernetes based on Fluentd and Fluent-bit.
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.
- Namespace isolation
- Native Kubernetes label selectors
- Secure communication (TLS)
- Configuration validation
- Multiple flow support (multiply logs for different transformations)
- Multiple output support (store the same logs in multiple storage: S3, GCS, ES, Loki and more...)
- Multiple logging system support (multiple fluentd, fluent-bit deployment on the same cluster)
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. Your logs will always be transferred on authenticated and encrypted channels.
- Logging-Operator v2 (soon)
- Advanced logging on Kubernetes
- Secure logging on Kubernetes with Fluentd and Fluent Bit
- Centralized logging under Kubernetes
- Centralized logging on Kubernetes automated
- And more...
Logging-operator is a core part of the Pipeline platform, a Cloud Native application and devops platform that natively supports multi- and hybrid-cloud deployments with multiple authentication backends. Check out the developer beta:
Available custom resources:
- logging - Represents a logging system. Includes
FluentdandFluent-bitconfiguration. Specifies thecontrolNamespace. Fluentd and Fluent-bit will be deployed in thecontrolNamespace - output - Defines an Output for a logging flow. This is a namespaced resource.
- flow - Defines a logging flow with
filtersandoutputs. You can specifyselectorsto filter logs by labels. Outputs can beoutputorclusteroutput. This is a namespaced resource. - clusteroutput - Defines an output without namespace restriction. Only effective in
controlNamespace. - clusterflow - Defines a logging flow without namespace restriction.
