docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'

这个错误通常是由于 Docker 守护进程没有运行或者 Docker 守护进程的 socket 文件没有正确的权限引起的。Docker 守护进程是一个后台进程,它管理着 Docker 容器的生命周期,以及 Docker 镜像的构建、保存和分发等功能。如果 Docker 守护进程没有运行,则无法管理 Docker 容器和镜像。
你可以通过以下命令来检查 Docker 守护进程的状态:
```
sudo systemctl status docker
```
如果 Docker 守护进程没有运行,则可以使用以下命令来启动它:
```
sudo systemctl start docker
```
如果 Docker 守护进程已经运行,但仍然无法连接到 Docker 守护进程的 socket 文件,则可以使用以下命令来检查权限:
```
ls -l /var/run/docker.sock
```
如果你看到的输出不是 `srw-rw----`,则需要更改该文件的权限:
```
sudo chmod 666 /var/run/docker.sock
```
这将确保当前用户和组都有与 Docker 守护进程的 socket 文件进行通信的权限。如果你仍然遇到问题,请告诉我。

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'.
The error message "Cannot connect to the Docker daemon" usually occurs when the Docker daemon is not running or not accessible. Here are a few steps you can take to troubleshoot this issue:
1. Verify that the Docker daemon is running: You can check the status of the Docker daemon by running the following command in your terminal:
```
sudo service docker status
```
If the daemon is not running, start it using:
```
sudo service docker start
```
2. Make sure you have proper permissions: Ensure that you have sufficient permissions to access the Docker daemon. By default, only root and users in the "docker" group can access it. You can add your user to the "docker" group using the following command:
```
sudo usermod -aG docker your_username
```
3. Verify that Docker is installed correctly: Ensure that Docker is installed properly on your system. You can verify this by running the following command:
```
docker version
```
4. Check if the Docker socket file exists: The error message suggests that Docker is trying to connect to the Unix socket at `/var/run/docker.sock`. Verify if this file exists by running:
```
ls -la /var/run/docker.sock
```
If none of these steps resolve the issue, please provide more details about your setup and any recent changes you made.

错误信息: "docker: 无法连接到 unix:///var/run/docker.sock 的 docker daemon。docker daemon 是否正在运行?请查看 'docker run --help'。"
意思是 Docker 客户端无法连接到 Docker Daemon 进程,请检查 Docker Daemon 是否正在运行,如果需要帮助请参考 "docker run --help"。
