Service Management

Manage the Docker service using standard systemctl commands.

# Start the Docker service
sudo systemctl start docker

sudo systemctl stop docker

# Restart the Docker service

# List all running containers
docker ps

# List all containers (running and stopped)
docker ps -a

# Build and start services

User Permissions

Cleanup Commands

To run Docker commands without sudo, your user has been added to the docker group. This change requires you to either log out and log back in, or run the following command in your current shell:

After this, you can run commands like docker ps instead of sudo docker ps.

Keep your system tidy by periodically removing unused Docker objects.

newgrp docker

# Remove all stopped containers, unused networks, and dangling images
docker system prune

# Remove all unused local volumes
docker volume prune
