我在我的 Ubuntu 16.04 机器上添加了 docker snap 包
sudo snap install docker

现在,当我尝试使用它时,出现以下错误...
无法连接到 Docker 守护程序。docker 守护进程是否在这台主机上运行?

由于不断发展的 snappy 模型中的限制问题,默认情况下 Docker 不是完整的(请参阅 Snapcraft 论坛上的讨论)。
获取有关如何解决(即打破)限制模型的一些有用说明,直到适当的修复到位。您可以简单地查看打包在 snap 包中的 Docker 帮助应用程序。
$ docker.help
Docker snap: Docker Linux container runtime.
Due to the confinement issues on snappy, it requires some manual setup to make docker-snap works on your machine.
We'll take you through the steps needed to set up docker snap work for you on ubuntu core and ubuntu classic.
On Ubuntu classic, before installing the docker snap,
please run the following command to add the login user into docker group.
sudo addgroup --system docker
sudo adduser $USER docker
newgrp docker
On Ubuntu Core 16, after installing the docker snap from store,
Firstly, you need to connect the two interfaces as they're not auto-connected by default.
sudo snap connect docker:account-control :account-control
sudo snap connect docker:home :home
Secondly, reload the snap and allows the user to login to the new group "docker-snap".
snap disable docker
snap enable docker
newgrp docker-snap
Then have fun with docker in snappy.

最后一条命令失败...
$ newgrp docker-snap
newgrp: group 'docker-snap' does not exist

但是,我没有注意到基于失败的任何负面影响,Docker 现在按我的预期运行。

如果 ...

...没有帮助,尝试删除并重新安装 docker
sudo snap remove docker --purge
