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'
