How can I locally debug the code of the workflow server? 🙏

[mio4kon]

I am currently using the 'Developing locally' approach with the k3d method. However, I can only debug by logging at the moment, and I have to rebuild it every time. Is there a good tutorial on how to use Golang for debugging the workflow-controller?"

I am currently following the approach outlined in https://argo-workflows.readthedocs.io/en/latest/running-locally/.

Yes, you can try it as below:

Envirentmont example:

ARCHIVED_WORKFLOW_GC_PERIOD=30s;ARGO_EXECUTOR_PLUGINS=false;ARGO_LOG_LEVEL=debug;ARGO_MANAGED_NAMESPACE=argo;ARGO_NAMESPACE=argo;ARGO_NAMESPACED=true;ARGO_PROGRESS_PATCH_TICK_DURATION=7s;ARGO_REMOVE_PVC_PROTECTION_FINALIZER=true;DEFAULT_REQUEUE_TIME=1s;LEADER_ELECTION_DISABLE=true;MAX_OPERATION_TIME=3600s;UPPERIO_DB_DEBUG=1;WORKFLOW_GC_PERIOD=30s

LEADER_ELECTION_DISABLE should be true and MAX_OPERATION_TIME should be increased in debug mode, other envs can be modified as needed.

Go Tool arguments:

-v -ldflags '-X github.com/argoproj/argo-workflows/v3.version=latest'

By the way, you can use kit ui to run argo server and ui without workflow-controller locally.

Thanks so much! I'll give it a try

@jswxstw hi，What does 'Kit UI' mean?
Right now, when I run make start API=true or make start UI=true, I get an error because the controller is already started for debugging. Are there any other commands to start the UI and Argo server separately?

[mio4kon]

I got it, 'Kit UI' is a command, haha! 🙏

Yes, make start => kit ${TASKS}
