Request entity too large: Where is it defined?

MotaOcimar · December 7, 2023, 8:43pm

Hi! A documentation question here:

I’m facing a Request entity too large: limit is 3145728 error and, although regarding the configmaps size limitation I found something documented, I didn’t find anything documented about the other Kuberntes yaml manifests.

So is this documented somewhere? And what would be the source cause of this limitation?

It’s tied to the default max request size in etcd

github.com

kubernetes/kubernetes/blob/89dfbebe2e823bd0b13e4b65b8460a058c7258a3/staging/src/k8s.io/apiserver/pkg/server/config.go#L433-L442C47


      
          		// 1.5MB is the recommended client request size in byte
          		// the etcd server should accept. See
          		// https://github.com/etcd-io/etcd/blob/release-3.4/embed/config.go#L56.
          		// A request body might be encoded in json, and is converted to
          		// proto when persisted in etcd, so we allow 2x as the largest request
          		// body size to be accepted and decoded in a write request.
          		// If this constant is changed, DefaultMaxRequestSizeBytes in k8s.io/apiserver/pkg/cel/limits.go
          		// should be changed to reflect the new value, if the two haven't
          		// been wired together already somehow.
          		MaxRequestBodyBytes: int64(3 * 1024 * 1024),

Thank you! It is what I was looking for
