Troubleshooting
macOS
- Install Docker
Make sure you have installed Docker Desktop for macOS.
brew install --cask docker
Or download Docker Desktop directly from: https://www.docker.com/products/docker-desktop
- Start Docker Desktop
Launch Docker Desktop from your Applications folder. The Docker icon will appear in your menu bar when it's running.
If you encounter issues, try restarting Docker Desktop from the menu bar icon or your Applications folder.
Docker Desktop will start automatically on boot by default. You can change this in Docker Desktop preferences if needed.

Follow the official installation guide: https://docs.docker.com/engine/install/

Make sure Docker is running. You can start the Docker service manually by typing:
sudo systemctl start docker
or you can add it to startup by typing:
sudo systemctl enable docker
- Add your user to the docker group
To run Docker without sudo, add your user to the docker group:
sudo usermod -aG docker $USER
Then log out and log back in for the changes to take effect, or run:
