在存储库 docker.io/library/nginx 中未找到最新标记

我正在尝试在 MAC 上安装 Docker。我遇到了以下问题

 predix-docker xxxxxx $ docker pull nginx
 Using default tag: latest
 latest: Pulling from library/nginx
 968c69f18673: Pulling fs layer
 963493e54e68: Layer already being pulled by another client. Waiting.
 755b4eb93a9e: Layer already being pulled by another client. Waiting.
 f3b2532b0301: Layer already being pulled by another client. Waiting.
 f3bf4daa2ff2: Layer already being pulled by another client. Waiting.

a2295636c7aa: Already exists
3035387b9e83: Already exists
 Pulling repository docker.io/library/nginx
Tag latest not found in repository docker.io/library/nginx

当我检查 Docker 镜像时，我找不到 nginx repo。请帮忙如何下载。

这是您这边的本地问题：

$ docker pull nginx
Using default tag: latest
Trying to pull repository docker.io/library/nginx ... 
latest: Pulling from docker.io/library/nginx

51f5c6a04d83: Already exists 
a3ed95caeb02: Pull complete 
51d229e136d0: Pull complete 
bcd41daec8cc: Pull complete 
Digest: sha256:0fe6413f3e30fcc5920bc8fa769280975b10b1c26721de956e1428b9e2f29d04
Status: Downloaded newer image for docker.io/nginx:latest

尝试移除图像（docker rmi nginx）并再次拉取它。

此外，看起来您正在运行并发拉取。

看起来 Docker 处理网络错误的方式是错误的。例如，DNS 超时可能会报告为“未找到标签 xxx”。这就是错误可能间歇性出现的原因。我见过几次这种情况，将 DNS 服务器更改为 google DNS (8.8.8.8) 并等待几分钟，就修复了这个 docker 错误。
