Describe the bug:

I'm a newbie and I want to configure the request body size. How do I configure it?

Steps To Reproduce:

• Installed K3s: curl -sfL https://rancher-mirror.rancher.cn/k3s/k3s-install.sh | INSTALL_K3S_MIRROR=cn sh -
• my traefik version:

# k3s crictl images | grep traefik
docker.io/rancher/mirrored-library-traefik   2.9.10                 d1e26b5f8193d       39.6MB

• install CRD

kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v2.9/docs/content/reference/dynamic-configuration/kubernetes-crd-definition-v1.yml
kubectl apply -f https://raw.githubusercontent.com/traefik/traefik/v2.9/docs/content/reference/dynamic-configuration/kubernetes-crd-rbac.yml

• my pods

# kubectl get pods -n kube-system

This seems to be a Traefik issue, but I'm not sure how to configure it. If you know how, please help me. Alternatively, can you suggest other methods, such as modifying the k3s configuration, to achieve my goal?

[Silvest89]

To be honest this issue does not belong here. K3s configuration does not apply here. It's traefik.
Middleware annotation should be:
traefik.ingress.kubernetes.io/middleware: default-request-body-limit@kubernetescrd

Thank you, you are correct. This was generated by chatGPT. It misled me.

I can move this to a discussion; as mentioned above K3s isn't the correct place to open issues (or ask questions) about Traefik. There is a dedicated forum for this on the Traefik project site.
