Description
I have identified a potential bug related to plugin debugging in a Kubernetes cluster deployment with SLB port forwarding.
The issue manifests as follows:
Suspected Root Cause
Key Observation
Steps to Reproduce
Additional Context
@dosubot[bot] commented on GitHub (Jan 23, 2026):
This error is a known regression in dify-plugin-daemon after v0.5.2 when running multiple pods in Kubernetes. The root cause is that plugin runtime registration and state are stored in local (in-memory) maps per pod, not shared across the cluster. So, when SLB routes requests to different pods, only the pod that registered the plugin runtime can serve requests; others return "plugin not found" errors. This behavior changed after v0.4.2, which did not enforce strict version matching or trigger the same race conditions in environment setup source.
The open-source version does not synchronize plugin runtime state between pods, and there is no built-in distributed locking or coordination for plugin environment initialization. Sharing persistent storage (PVC) helps avoid plugin data loss after restarts, but does not solve runtime registration sync source. The ControlPanel watchdog logic in v0.5.1+ can cause concurrent environment initialization across pods, leading to race conditions and unpredictable failures source.
Workarounds: run a single replica, avoid sharing plugin working directories (but share plugin/package directories), or implement a custom distributed lock (e.g., Redis) for environment setup. If you need true multi-pod support, a distributed locking mechanism is required to serialize plugin environment initialization source. Also, ensure plugin configuration version numbers match exactly in v0.5.2+ source.
There is no official solution for multi-pod runtime registration sync in the open-source codebase as of the latest versions. The enterprise edition may have features to address this, but for open-source, these architectural limitations remain source.
To reply, just mention @dosu.

@fatelei commented on GitHub (Jan 28, 2026):
because the dify-plugin-daemon origin code is not support replica, you can change the code, add
app.pluginManager.AddClusterTunnel(app.cluster), you need implement the methodAddClusterTunnel, after modify the code, different k8s pod will sync the python package install info, so it will not lead the error: no avaiable node@fatelei commented on GitHub (Jan 28, 2026):
if you do want modify the code, you need use serverless to deploy plugin
