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.
