原本已经用 docker 部署好了 PHP的 container，以及 composer 的依赖。

最近需要更新一个依赖，执行 “`dcoker-compose exec php composer require “myTeam/xxxx”“`却报：

[runtimeexception]
Failed to execute git clone --mirror "git@gitlab.com:XXXXXX" "~/.cache/composer/vcs/bitbucket.orgXXXXXXXX.git/"
Cloning into bare repository '"~/.cache/composer/vcs/bitbucket.orgXXXXXXXX.git'…
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

查了网上其它人方案，都无法解决，例如：

1.修改 ~/.ssh/ 下 config 及 id_rsa, id_rsa.pub, known_hosts 等文件的权限为 600 或 400

2.清除 composer 缓存

3.确认 Git 环境变量 或 用户名密码/token

4.把 docker 的 container、image 全部删掉，重新部署

……

……

以上种种都不能解决

后面判断主要问题还是在 ~/.ssh/中各个文件的权限上，因为 docker container 里的ssh文件是从Ubuntu中复制进去的，权限属性跟Ubuntu下的 ~/.ssh/ 一样，唯一不同的是 container 里面的 owner 是 1000

docker-compose exec php bash 进入container

而 container 中使用的是 root ， 所以试着把这4个文件的 owner 改为 root

退出，再执行“`dcoker-compose exec php composer require “myTeam/xxxx”“`，终于可以正常更新了。

【后续】

今天是 2021/04/13，执行 docker-compose exec php composer install 时又报 RuntimeException 了~ 提示如下

折腾了半天，用尽之前的办法还是无法解决，后面又找到了一个新的处理方法

sudo chown root:$USER ~/.ssh/config
sudo chmod 644 ~/.ssh/config
docker-compose exec php composer clear
docker-compose exec php composer install

注意：

1.如果 composer clear 后还是无法安装，可以试着手动把 ~/.cache/composer/ 下的 vcs 目录删除一下

2.我登录的用户并不是root，只是把当前用户加入【docker组】和【root组】
