Unable to run docker commands

If you encounter issues while running docker pull or docker run commands, here are some common resolutions with links to official Docker documentation:

1. Docker not installed: If Docker is not installed on your system, follow the official Docker installation guide for your operating system.

2. Permission denied: If you receive a "permission denied" error, you may need to run the Docker commands with sudo. Alternatively, you can follow the Docker post-installation steps to add your user to the "docker" group.

3. Docker daemon not running: If the Docker daemon is not running, you can start it by following the instructions in the Docker documentation.

4. Network issues: If you encounter network-related issues while pulling or running Docker images, refer to the Docker networking troubleshooting guide.

5. Image not found: If the Docker image you're trying to pull is not found, ensure you're using the correct image name and tag. You can also try pulling from a different Docker registry or mirror.

6. Container exited with error: If your Docker container exits with an error, check the container logs using docker logs <container_id> and refer to the Docker troubleshooting guide for more information.

7. Resource constraints: If you encounter resource-related issues (e.g., insufficient memory or CPU), refer to the Docker resource constraints documentation for guidance on managing container resources.

For more detailed troubleshooting and advanced scenarios, consult the official Docker documentation and Docker troubleshooting guide.
