tcp - 在 docker 中尝试 docker 获取 TCP 连接被拒绝错误

Question

我正在尝试在 docker 中运行 docker 并得到 TCP 127.0.0.1:5000: connection refused。谁能解释为什么会这样以及我该如何解决。

这是我已经厌倦的:

docker run -it --privileged --name docker-server-test -d docker:1.7-dind

docker run --rm --link docker-server:docker docker:1.7 pull my-server:5000/qe/busybox

Answer 1

看起来您正在尝试从本地计算机上运行的注册表中提取图像 - 在这种情况下，当您指定 localhost 作为从中提取图像的位置时，它会尝试从相对于 Docker 守护程序容器的 localhost 拉取(这不是您的注册表正在监听的位置)。您可能想改为从 host-ip:5000/qe/busybox 拉取(可能类似于 192.168.0.x:5000/qe/busybox)。
