由于gitlab是部署在k8s集群上的，所以gitlab需要通过ingress发布出去，后面的pull，push操作都是经过nginx的

解决方法
修改ingress-nginx的默认http上传文件大小（默认文件大小不能超过1MB），导致上传失败，出现了413问题。

# kubectl exec -it ingress-nginx-controller-rgf4j -n ingress-nginx -- bash
bash-5.1$ 
bash-5.1$ nginx -t
2023/08/19 07:31:22 [warn] 858#858: the "http2_max_field_size" directive is obsolete, use the "large_client_header_buffers" directive instead in /etc/nginx/nginx.conf:144

bash-5.1$ 
bash-5.1$ cp /etc/nginx/nginx.conf{,.bak20230819}
bash-5.1$ vi /etc/nginx/nginx.conf
找到如下字段修改为300m
client_max_body_size                    300m;
···
编辑nginx.conf后执行nginx -t检查配置文件
没问题执行nginx -s reload

再次推送
