`snap` 从 docker 容器内部失败

Question

我从 hub.docker.com 拉取了最新的 Ubuntu 镜像

$ docker pull ubuntu

一切都下载正确，所以我启动了容器

$ docker run -it ubuntu

我安装snapd到容器中

# apt update
...
All packages are up to date.
# apt install snapd
Get:1 http://security.ubuntu.com/...
...
done.

当我尝试登录时，我遇到了失败

# snap login
2017/04/20 18:06:04.729212 main.go:220: WARNING: cannot create syslog logger
Email address: <me@email.com>
Password of "me@email.com":
error: cannot communicate with server: Post http://localhost/v2/login: dial unix /run/snapd-snap.socket: connect: no such file or directory

我什至试图sudo确定...

# sudo snap login
bash: sudo: command not found

要让 snapd 在 Docker 容器中工作，需要做的还不止这些。在这里查看 Ogra 的容器： https://github.com/ogra1/snapd-docker
