gitlab-runner中使用docker模式，设置volumes将yarn的全局缓存保存到数据卷中问题
### 问题描述
在设置gitlab-runner中模式选为docker
### 问题出现的平台版本
```
yarn -v
v1.22.5
```
```
node -v
v16.3.0
```
```
docker -v
Docker version 20.10.7, build f0df350
```
```
gitlab-runner -v
Version: 13.12.0
Git revision: 7a6612da
Git branch: 13-12-stable
GO version: go1.16.3
Built: 2021-05-20T23:59:54+01:00
OS/Arch: darwin/amd64
```
### 相关代码
这个是我的gitlab-runner config
/usr/local/share/.cache/为镜像中yarn的全局缓存目录
```
concurrent = 1
check_interval = 0
[session_server]
session_timeout = 1800
[[runners]]
name = "xxxx"
url = "http://xxxxx"
token = "xxxxxx"
executor = "docker"
[runners.custom_build_dir]
[runners.cache]
[runners.cache.s3]
[runners.docker]
tls_verify = false
image = "node"
privileged = false
disable_entrypoint_overwrite = false
oom_kill_disable = false
disable_cache = false
volumes = ["/Users/xxxx/home/cache:/usr/local/share/.cache/"]
```
这个是我.gitlab-ci.yml文件
```
image: node
stages:
- build
variables:
GIT_STRATEGY: clone
build:
stage: build
image: node
script:
- yarn install
only:
- feature/1.0.0
tags:
- fe
timeout: 10m
```
### 你期待的结果是什么？实际看到的错误信息又是什么？
在ci执行到script时，yarn会显示网络错误，我确保我挂靠到volumes的文件权限为777
```
$ yarn install --har
yarn install v1.22.5

我期待得到的结果是我的依赖安装完成。
