npm install 在构建 docker 镜像时返回连接超时

Question

我正在尝试制作一个 docker 图像，包括newman. 我尝试使用 构建图像node:10-alpine，但在npm install -g newman. 这是我的 docker 命令：

RUN set http_proxy= && \
    set https_proxy= && \
    yarn config delete proxy && \
    npm config rm https-proxy && \
    npm config rm proxy && \
    npm config set registry http://registry.npmjs.org/ && \
    npm config set strict-ssl false && \
    npm cache clean --force && \
    npm cache verify && \
    npm install -g newman

完整的错误是：

npm ERR! errno ECONNREFUSED

然后我尝试制作我的图像，alpine:3.8而apk update. 这是我的第二个版本：

RUN apk update && apk add --no-cache nodejs npm
RUN npm install -g newman

完整的错误日志是：

我还尝试使用--network=host选项构建图像；但在两个版本中都出现了相同的错误。

另外ping dl-cdn.alpinelinux.org在我的系统上工作正常。

另外重启了docker服务，再试sudo systemctl restart docker一次。再次得到相同的结果。

就我而言，适用以下步骤：

1. 在主机中，我更改主机服务器/etc/sysctl.conf：

我添加了

net.ipv4.ip_forward=1

2. 我用

   nslookupregistry.npmjs.org

给我IP 104.16.25.38

3. Docker 使用 IP 构建

码头工人构建。--add-hostregistry.npmjs.org:104.16.25.38 -t 测试
