Docker push error "413 Request Entity Too Large"

Question

I setup the registry v2 and use nginx as reverse proxy. When I push the image to registy, it error out 413 Request Entity Too Large.

I have modify the client_max_body_size as 20MB in nginx.conf. The push still fails.

client_max_body_size 20M;

What is the body size in docker push? How can I limit the body size?

Answer 1

Docker documentation mentions the limit should be turned off:

http {
    ...
    # disable any limits to avoid HTTP 413 for large image uploads
    client_max_body_size 0;
    ...
}

Answer 2

For anyone getting this error in Kubernetes you need to add this annotation to the registry Ingress resource:

nginx.ingress.kubernetes.io/proxy-body-size: "0"

Answer 3

You should increase the available memory to 300 MB with:

client_max_body_size 300M;
