关于 POST git-receive-pack (chunked) HTTP code = 413

1. 背景介绍

团队使用 Gitlab 管理代码，按照以下结构部署：

• Nginx 反向代理，转发到 Gitlab Docker
• Gitlab Docker + Docker Volume

最近 Push 代码时经常发生 413 错误，详细错误信息如下：

POST git-receive-pack (chunked)
error: RPC failed; result=22, HTTP code = 413

发生 413 错误通常有以下两种情况：

• 单个文件太大
• 单个 commit 包含太多的文件，例：项目初始阶段添加的第三方 JAR / SO 文件

解决方案

• Change protocol from http(s) to git/ssh
• Increase git http post buffer size
• Increase server (nginx) buffer size

2. 原因分析

2.1. 查找大文件

find . -size +10M

2.2. 待 Push 文件列表

git diff --stat --cached origin/master

2.3. 查看当前 postBuffer 值

Run this command in root folder of git repository ( by doing so you will search in ~/.gitconfig and .git/config files ):

git config --get http.postBuffer

3. 解决方案

3.1. 增加 postBuffer

打开 SourceTree 右上角的 Settings

• Advanced
• Edit Config File ...

打开配置文件，添加如下配置

[http] 
      postBuffer = 524288000

3.2. 增加 client_max_body_size

gitlab.conf

location / {
    client_max_body_size 50M;
}

docker-compose.yml

version: '3'
services:
  web:
    environment:
      GITLAB_OMNIBUS_CONFIG: |
        nginx['client_max_body_size'] = '50m'
