docker - Alpine 包安装协议(protocol)错误

Question

我正在尝试在 alpine 3.6 上安装 git。它在第一个实例中失败，并出现协议(protocol)错误，但在第二个实例中可以正常工作。具体来说，首先没有安装 pcre 和 libcurl。这是我正在尝试做的事情的日志。

$ docker run -it alpine:3.6 /bin/sh
/ # apk --update add git
fetch http://dl-cdn.alpinelinux.org/alpine/v3.6/main/x86_64/APKINDEX.tar.gz

再次安装 pcre/git 就可以了。

我也遇到了这个问题(令人惊讶的是，它是确定性的)，并且更换镜像有效。例如，执行:

$ echo "https://mirror.csclub.uwaterloo.ca/alpine/v3.7/main" >/etc/apk/repositories
$ echo "https://mirror.csclub.uwaterloo.ca/alpine/v3.7/community" >>/etc/apk/repositories

将镜像更改为 UWaterloo 服务器。您可以找到完整的镜像列表 here .
