docker - 无法从容器内部连接到内部网络

问题描述

我有以下 Dockerfile：

FROM node:8
WORKDIR /tmp
COPY package.json /tmp/
RUN npm config set registry http://xxx:8081/repository/npm-group/
RUN npm install

WORKDIR /opt/app
COPY . /opt/app/
RUN cp -a /tmp/node_modules /opt/app/

EXPOSE 3000

ENTRYPOINT [ "npm", "start" ]

当我尝试使用以下方法构建图像时：

docker build -t blah .

一切顺利，直到我进入第 5/10 步，npm install。日志显示：

npm ERR! errno ETIMEDOUT
npm ERR! network request to http://xxx:8081/repository/npm-group/prop-types failed, reason: connect ETIMEDOUT x.x.x.x:8081

我不知道发生了什么。Nexus 存储库托管在内部网络上，所以我不知道为什么无法联系到它。

iptables 显示以下内容：

target     prot opt source               destination         
RETURN     all  --  anywhere             anywhere

有任何想法吗？
