Knative Eventing sources

Event Sources are Kubernetes Custom Resources which provide a mechanism for registering interest in a class of events from a particular software system. Since different event sources may be described by different Custom Resources, this page provides an index of the available source resource types as well as links to installation instructions.

This is a non-exhaustive list of Event sources for Knative.

Inclusion in this list is not an endorsement, nor does it imply any level of support.

Sources

These are sources that are installed as CRDs.

Name	Status	Support	Description
AWS SQS	Proof of Concept	None	Brings AWS Simple Queue Service messages into Knative.
Apache Camel	Proof of Concept	None	Allows to use Apache Camel components for pushing events into Knative.
Apache CouchDB	Active Development	None	Brings Apache CouchDB messages into Knative.
Apache Kafka	Proof of Concept	None	Brings Apache Kafka messages into Knative.
BitBucket	Proof of Concept	None	Registers for events of the specified types on the specified BitBucket organization/repository. Brings those events into Knative.
CloudAuditLogsSource	Active Development	None	Registers for events of the specified types on the specified Google Cloud Audit Logs. Brings those events into Knative.
CloudPubSubSource	Active Development	None	Brings Cloud Pub/Sub messages into Knative.
CloudSchedulerSource	Active Development	None	Create, update, and delete Google Cloud Scheduler Jobs. When those jobs are triggered, receive the event inside Knative.
CloudStorageSource	Active Development	None	Registers for events of the specified types on the specified Google Cloud Storage bucket and optional object prefix. Brings those events into Knative.
Cron Job	Replaced by PingSource	None	Deprecated, replace with PingSource or a CronJob using SinkBinding
GitHub	Proof of Concept	None	Registers for events of the specified types on the specified GitHub organization/repository. Brings those events into Knative.
GitLab	Proof of Concept	None	Registers for events of the specified types on the specified GitLab repository. Brings those events into Knative.
Kubernetes	Active Development	Knative	Brings Kubernetes API server events into Knative.
Ping	In development	None	Uses an in-memory timer to produce events with a fixed payload on a specified cron schedule.
VMware	Active Development	None	Brings vSphere events into Knative.

Meta Sources

These are not directly usable, but make writing a Source much easier.

Name	Status	Support	Description
Auto Container Source	Proof of Concept	None	AutoContainerSource is a controller that allows the Source CRDs without needing a controller. It notices CRDs with a specific label and starts controlling resources of that type. It utilizes Container Source as underlying infrastructure.
Container Source	Active Development	Knative	Given a `spec.template` with at least a container image specified, ContainerSource will keep a `Pod` running with the specified image(s). `K_SINK` (destination address) and `KE_CE_OVERRIDES` (JSON CloudEvents attributes) environment variables are injected into the running image(s). It is used by multiple other Sources as underlying infrastructure.
Sample Source	Active Development	Knative	Used as reference implementation supporting Writing an Event Source from Scratch tutorial.
SinkBinding	Active Development	Knative	SinkBinding provides a framework for injecting `K_SINK` (destination address) and `K_CE_OVERRIDES` (JSON cloudevents attributes) environment variables into any Kubernetes resource which has a `spec.template` that looks like a Pod (aka PodSpecable).

ContainerSource Containers

These are containers intended to be used with ContainerSource. See the docs here.

Name	Status	Support	Description
AWS CodeCommit	Supported	TriggerMesh	Registers for events of the specified types on the specified AWS CodeCommit repository. Brings those events into Knative.
AWS Cognito	Supported	TriggerMesh	Registers for AWS Cognito events. Brings those events into Knative.
AWS DynamoDB	Supported	TriggerMesh	Registers for events of on the specified AWS DynamoDB table. Brings those events into Knative.
AWS Kinesis	Supported	TriggerMesh	Registers for events on the specified AWS Kinesis stream. Brings those events into Knative.
AWS SNS	Supported	TriggerMesh	Registers for events of the specified AWS SNS endpoint. Brings those events into Knative.
AWS SQS	Supported	TriggerMesh	Registers for events of the specified AWS SQS queue. Brings those events into Knative.
FTP / SFTP	Proof of concept	None	Watches for files being uploaded into a FTP/SFTP and generates events for those.
Heartbeat	Proof of Concept	None	Uses an in-memory timer to produce events as the specified interval. Uses AutoContainerSource for underlying infrastructure.
Heartbeats	Proof of Concept	None	Uses an in-memory timer to produce events at the specified interval.
K8s	Proof of Concept	None	Brings Kubernetes cluster events into Knative. Uses AutoContainerSource for underlying infrastructure.
WebSocket	Active Development	None	Opens a WebSocket to the specified source and packages each received message as a Knative event.

SinkBindings

These are containers intended to be used with SinkBinding. See the docs here.

Name	Status	Support	Description
Konnek	Active Development	None	Retrieves events from cloud platforms (like AWS and GCP) and transforms them into CloudEvents for consumption in Knative.
