who could upgrade kubesphere/fluent-bit image
fluent bit v1.8.3 has an issue about cpu and RAM, and this issue has been fixed in fluent bit v1.8.11. But the fluent bit version in kubesphere is kubesphere/fluent-bit:v1.8.3
I try to edit https://github.com/fluent/fluentbit-operator/blob/master/cmd/fluent-bit-watcher/Dockerfile ( replace FROM fluent/fluent-bit:1.8.3 with FROM fluent/fluent-bit:1.8.11 ) and build a new image. It works, but I'm not sure the way to call someone upgrade the image kubesphere/fluent-bit version

You can try this kubespheredev/fluent-bit:v1.8.11.
You can try this
kubespheredev/fluent-bit:v1.8.11.
It seems work, maybe. I'm not find any exception about CPU & RAM with it running several hours in my cluster.
