If you are creating a new function, see theConsole Quickstarton Cloud Run. The content on this page only applies to existing legacy functions created with the Cloud Functions v1 API.
You can write a function usingMicronaut, and deploy it to Java using Micronaut's
Cloud Run functions support. For details, see theMicronaut documentation.
Quarkus
You can write a function usingQuarkus, and deploy it to
Cloud Run functions using Quarkus Cloud Run functions support. For
details, see theQuarkus documentation.
