docker - 我怎样才能让 docker 与我的用户一起工作(ubuntu)

Question

这是目前的情况:

hamsterofdeath@HodVm:~$ docker ps
Cannot connect to the Docker daemon at unix:///home/hamsterofdeath/.docker/desktop/docker.sock. Is the docker daemon running?
hamsterofdeath@HodVm:~$ sudo docker ps
[sudo] password for hamsterofdeath: 
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
hamsterofdeath@HodVm:~$ docker ps
Cannot connect to the Docker daemon at unix:///home/hamsterofdeath/.docker/desktop/docker.sock. Is the docker daemon running?
hamsterofdeath@HodVm:~$ sudo groupadd docker
groupadd: group 'docker' already exists
hamsterofdeath@HodVm:~$ sudo gpasswd -a ${USER} docker
Adding user hamsterofdeath to group docker
hamsterofdeath@HodVm:~$ docker ps
Cannot connect to the Docker daemon at unix:///home/hamsterofdeath/.docker/desktop/docker.sock. Is the docker daemon running?
hamsterofdeath@HodVm:~$ 

cat/etc/group 给了我“docker:x:996:hamsterofdeath”
注销并再次登录不会改变任何事情。我也试过:

sudo usermod -aG docker $USER
sudo usermod -a -G docker $USER

但它没有效果。我需要做什么？
我总是得到:

Cannot connect to the Docker daemon at unix:///home/hamsterofdeath/.docker/desktop/docker.sock. Is the docker daemon running?

或者

Error response from daemon: dial unix /home/hamsterofdeath/.docker/desktop/docker.raw.sock: connect: connection refused

使用 sudo，它可以工作
可能还有另一个(？)问题
我通过删除 docker

sudo apt remove docker

但是“docker”命令仍然存在。

amsterofdeath@HodVm:~$ sudo apt remove docker
[sudo] password for hamsterofdeath: 
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package 'docker' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
hamsterofdeath@HodVm:~$ docker ps
Cannot connect to the Docker daemon at unix:///home/hamsterofdeath/.docker/desktop/docker.sock. Is the docker daemon running?
hamsterofdeath@HodVm:~$ 

Answer 1

你可以试试:

尝试重新启动 bash 进程和可能的机器。

查看 docker 组是否与 .sock 文件关联

这应该什么都不返回:stat -c %U:%G /home/hamsterofdeath/.docker/desktop/docker.raw.sock | grep -v root:docker如果确实如此:chown root:docker /home/hamsterofdeath/.docker/desktop/docker.raw.sock

$USER 是否填充了正确的数据？

使用 sudo systemctl 重启 docker 引擎

否则转到 Post-Install并尝试那里的所有步骤，特别是因为它似乎是一个虚拟机重新启动它
Next Docker Desktop 相当粗略。我个人推荐使用 VS-Code Docker 扩展，因为它提供了与 docker desktop 几乎相同的功能，并且在 Ubuntu 上运行良好。见 Docker Extension VS-Code
