Restart Docker Service to Resolve Connection Issue
The error indicates that the Docker client is unable to communicate with the Docker daemon, which may not be running or is misconfigured. This can happen if the Docker service has crashed, is not started, or if there are permission issues with accessing the Docker socket.

- 1
Check Docker Service Status
Verify if the Docker service is currently running on your system. Use the following command to check its status.
bashsudo systemctl status docker - 2
Start Docker Service
If the Docker service is not running, start it using the command below. This will initiate the Docker daemon.
bashsudo systemctl start docker - 3
Check User Permissions
Ensure that your user has permission to access the Docker socket. You can add your user to the Docker group with the following command. Replace 'your_username' with your actual username.
bashsudo usermod -aG docker your_username - 4
Log Out and Back In
After adding your user to the Docker group, log out of your session and log back in to apply the group changes.

Verify Docker Functionality
Run a simple Docker command to verify that the connection to the Docker daemon is now successful.
bashdocker ps
Validation
If the command 'docker ps' returns a list of running containers (or an empty list if none are running), the issue is resolved. If you still encounter the same error, revisit the previous steps to ensure they were completed successfully.
