Docker 无法从Google cloud build访问pip主机

我正在尝试使用google cloud build创建docker映像，但它无法访问pip主机

下面是我得到的错误行

RUN pip install -vvv --extra-index-url http://[pip host] --trusted-host [pip host] -r requirements.txt

步骤2：步骤7/10：运行pip安装--额外索引url http://[pip主机]--受信任主机[pip主机]-r requirements.txt
步骤2:-->在1400ecddf71f2中运行
步骤2：查找索引：https://pypi.org/simple，http://[pip主机]/simple/
步骤2：收集[some package==version]（来自-r requirements.txt（第1行））
步骤#2：警告：在连接被“ConnectTimeoutError（，“连接到[pip主机]超时。（连接超时=15）”：简单/[某个包]中断后重试（重试（总计=4，连接=None，读取=None，重定向=None，状态=None））/

提前感谢

pip主机是一个私有主机，您是否可以共享cloudbuild.yaml，显然可以编辑任何私有信息cloudbuild.yaml

步骤：-name:'gcr.io/cloud builders/docker'args:['build'，'--network=cloudbuild'，'-t'，gcr.io/${PROJECT\u ID}/image\u name:$BRANCH\u name'、'-f'、'Dockerfile'、'..'.]

Dockerfile

运行pip安装--额外索引url http://[pip主机]--受信任主机[pip主机]-r requirements.txt

您能尝试ping[pip主机]吗？看看它是否回答了这个问题，并且在这一点上是可以访问的
