我正在尝试制作一个包括newman的docker镜像。我试图使用node:10-alpine构建镜像，但是在执行npm install -g newman时出现连接被拒绝的错误。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
完整的错误信息如下：

我尝试使用 alpine:3.8 创建我的镜像，但当执行 apk update 时出现仓库错误。这是我的第二个版本：
RUN apk update && apk add --no-cache nodejs npm
RUN npm install -g newman
完整的错误日志如下：

我还尝试使用--network=host选项构建镜像；但两个版本都遇到了相同的错误。
另外，ping dl-cdn.alpinelinux.org在我的系统上运行良好。
此外，重新启动了docker服务sudo systemctl restart docker，然后再次尝试。但是结果仍然相同。
