You can do the same with Rancher's existing taints, or with your own custom ones. You can do the same with Rancher's existing taints, or with your own custom ones.
**Why do we not schedule logging-related pods on Windows nodes?** **Are clusters with Windows worker nodes supported?**
No parts of the logging stack are compatible with Windows Kubernetes nodes. Yes, clusters with Windows worker support logging with some small caveats...
For instance, if a logging pod is attempting to pull its image from a container registry, there may only be Linux-compatible images available.
In this scenario, the pod would be stuck in an ```ImagePullBackOff``` status; and would eventually change to a ```ErrImagePull``` status. 1. Windows node logs are currently unable to be exported.
2. ```fluentd-configcheck``` pod(s) will fail due to an [upstream issue](https://github.com/banzaicloud/logging-operator/issues/592), where ```tolerations``` and ```nodeSelector``` settings are not inherited from the ```logging-operator```.
