Question

当我在 Linux VM docker 文件中运行 docker 文件时，我有一个 docker 文件可以从远程存储库获取包，创建 docker 映像没有任何问题。

当我从 Jenkins 管道调用时相同的 Docker 文件无法访问网络。

cat Dockerfile
FROM docker-registry-remote.artifactory.myrepo.com/node
ADD myapp /usr/src/app/myapp
ENV http_proxy=http://10.1.2.3:8080/
ENV https_proxy=http://10.1.2.3:8080/
RUN apt-get update

Jenkins 构建日志 Err:9 http://deb.debian.org/debian stretch/main amd64 Packages Cannot initiate the connection to 10.1.2.3:8080 (10.1.2.3). - connect (101: Network is unreachable)

来自 jenkins vm 的 ping 测试

我在构建 docker 镜像时使用 --network 主机选项解决了上述问题。

docker build -f Dockerfile --network host --no-cache -t mytag .

Dockerfile 无法连接代理服务器
