docker 一直在Waiting for the Docker Engine...

这种情况可能是由于 Docker 服务未启动导致的。可以尝试以下步骤：

1. 检查 Docker 服务是否已启动。在终端中运行以下命令：

   sudo service docker status

如果服务未启动，则执行以下命令启动 Docker 服务：

   sudo service docker start

2. 如果 Docker 服务已启动，但是仍然无法连接 Docker 引擎，请检查 Docker 守护进程是否正在运行。运行以下命令：

   ps aux | grep dockerd

如果守护进程未运行，请执行以下命令启动守护进程：

   sudo dockerd

3. 如果以上步骤仍然不能解决问题，可以尝试重新安装 Docker。首先卸载 Docker：

   sudo apt-get remove docker docker-engine docker.io containerd runc

然后重新安装 Docker。可以按照 Docker 官方文档上的指引进行安装：https://docs.docker.com/engine/install/ubuntu/

Waiting for the Docker Engine...

If you are waiting for the Docker Engine to start up, there could be a few reasons why it is taking longer than expected. Here are some possible solutions:

1. Check your Docker installation: Make sure you have Docker installed on your system correctly and that it is up to date. You can check the version of Docker by running the command `docker version` in your terminal.

2. Check your system resources: Docker can be resource-intensive, so if you are running other applications or services on your machine, it could be slowing down the Docker Engine. Try closing any unnecessary applications or services and see if that helps speed up the Docker Engine.

3. Increase the resources allocated to Docker: You can allocate more resources to Docker by adjusting the settings in the Docker application. Open Docker, go to Preferences, and then click on Resources. From there, you can adjust the amount of CPU and memory that Docker is allowed to use.

4. Restart Docker: Sometimes, simply restarting the Docker Engine can help resolve issues. You can restart Docker by running the command `sudo systemctl restart docker` in your terminal.

I hope one of these solutions helps you resolve the issue and get Docker up and running quickly!

Waiting for the Docker Engine.

如果你在启动Docker时看到了"Waiting for the Docker Engine"的消息，这可能意味着Docker引擎还没有启动或正在启动中。

以下是一些可能的解决方案：

1. 等待一段时间
启动Docker时，有时需要等待一段时间才能启动成功。你可以等待一段时间，再重新尝试启动Docker。

2. 检查Docker引擎状态
可以使用以下命令检查Docker引擎的状态：

$ sudo systemctl status docker

如果Docker引擎正在运行，将看到类似于以下内容的输出：

● docker.service - Docker Application Container Engine
   Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
   Active: active (running) since Mon 2021-10-18 14:49:21 UTC; 1 weeks 0 days ago
     Docs: https://docs.docker.com
 Main PID: 1310 (dockerd)
    Tasks: 21
   Memory: 38.4M
      CPU: 1.832s
   CGroup: /system.slice/docker.service
           ├─1310 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
           └─1476 docker-containerd --config /var/run/docker/containerd/containerd.toml

如果Docker引擎未运行，则可以使用以下命令启动它：

$ sudo systemctl start docker

3. 检查Docker引擎配置
确保Docker引擎配置正确。你可以检查/etc/docker/daemon.json文件中的配置，例如：

{
  "debug": true,
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  },
  "storage-driver": "overlay2"
}

希望这些解决方案能帮助你解决"Waiting for the Docker Engine"的问题。
