A Loki powered log provider for OpenFaaS
OpenFaaS Loki implementes the new log provider interface from faas-provider
. This means you can query Loki for your function logs with the faas-cli
!
Limitations: This initial version does not support log tail streams. This means that faas-cli logs
will alway behave as if --follow=false
. Live tailing of the logs is currently being worked on.
All other OpenFaaS log behaviors should be fully supported. Issues are welcome if you notice a bug or room for improvement.
