Docker Daemon Is Not Running
If you encounter issues with Docker, one common problem is when the Docker daemon is not running. The Docker daemon is a background service responsible for managing Docker containers and images.
Checking Docker Daemon Status
The first step is to check the status of the Docker daemon. Open your terminal or command prompt and run the following command:
If the Docker daemon is running, you will see detailed information about your Docker installation. If the daemon is not running, you will likely see an error indicating that the Docker client cannot connect to the Docker engine.
Restarting Docker Service
A simple solution to restart the Docker daemon is to restart the Docker service. The steps to do this depend on your operating system.
sudo systemctl restart docker
You can restart Docker Desktop from the menu.
You can restart Docker Desktop from the system tray icon.
After restarting the Docker service, check the status again using
docker info to see if the issue is resolved.
Checking Docker Permissions
If you are running Docker on Linux, make sure that your user has the necessary permissions to interact with the Docker daemon. By default, Docker commands require root access or elevated privileges.
To avoid using
sudo with Docker commands, you can add your user to the
sudo usermod -aG docker $USER
Log out and log back in or restart your system to apply the group membership changes.
Checking Disk Space
Another reason for the Docker daemon not running could be low disk space on the system where Docker is installed. Check the available disk space to ensure it's not a disk space issue causing the problem.
