A Cron Connector for OpenFaaS
This is a cron event connector for OpenFaaS. This was built to provide a timer interface to trigger OpenFaaS functions. Also checkout OpenFaas docs on cron for other methods on how you can run functions triggered by cron.
How to Use
You need to have OpenFaaS deployed first, see https://docs.openfaas.com to get started
Works with both armd64 and armhf (Raspberry Pi).
- For Docker Swarm:
curl -s https://raw.githubusercontent.com/zeerorg/cron-connector/master/yaml/docker-compose.yml | docker stack deploy func -c -
- For Kubernetes:
curl -s https://raw.githubusercontent.com/zeerorg/cron-connector/master/yaml/kubernetes/connector-dep.yml | kubectl create --namespace openfaas -f -
The function should have 2 annotations:
topicannotation should be
scheduleannotation should be the cron schedule on which to invoke function
For example, we may have a function "nodeinfo" which we want to invoke every 5 minutes:
functions: nodeinfo: image: functions/nodeinfo annotations: topic: cron-function schedule: "*/5 * * * *"
