Do Azure Container Apps support DAPR Workflows?

Question

Official documentation states DAPR workflows are not supported in container apps.
Is this still the case?

I was able to run a simple DAPR workflow using the managed DAPR provided by container apps. I gave it a go after noticing the following logs in the DAPR sidecar.

msg="Configuring workflow engine with actors backend"
msg="Registering component for dapr workflow engine..."
msg="Initializing Dapr workflow component" app_id=dapr-test component="dapr (workflow.dapr/v1)"
msg="Workflow engine initialized." app_id=dapr-test instance=dapr-test--ddg0y85-58bc6b74fb-dhr2z scope=dapr.runtime type=log ver=1.13.6-msft.6

Answer 1

Azure Container Apps do not support Dapr workflows. While you may have been able to run a simple Dapr workflow using the managed Dapr provided by Container Apps, the official documentation states that Dapr workflows are not supported in this environment. Therefore, any successful execution you observed may not be guaranteed or officially supported by Microsoft.

Answer 2

Hello @Aaron

Thank you for reaching out Microsoft Q&A.

I could see the above log where initialization of DAPR workflow engine is done. However, Microsoft as mentioned in the below documentation, every Dapr capability undergoes thorough evaluation but it isn't guaranteed while Tier 1 components are fully supported, Tier 2 components are supported with best effort.
