Docker Command Cheat Sheet for Beginners 🐳

🔧 Commonly Used Docker Commands

• Start Docker:

  systemctl start docker
  

• Check Docker version:

  docker --version
  

📦 Working with Containers - List running containers:

• List running containers:

  docker ps
  

• List all containers (Running + Stopped):

  docker ps -a
  

• Run a container (start and attach):

  docker run <image_name>
  

• Run in Detached mode:

  docker run -d <image_name>
  

• Run with port mapping:

  docker run -p <host_port>:<container_port> <image_name>
  

• Stop a running container:

  docker stop <container_id>
  

• Restart a stopped container:

  docker start <container_id>
  

• Remove a stopped container:

  docker rm <container_id>
  

📜 Image Management - List Docker images:

• List Docker images:

  docker images
  

• Pull an image from Docker Hub:

  docker pull <image_name>
  

• Build an image from a Dockerfile:

  docker build -t <image_name> .
  

• Tag an image:

  docker tag <image_id> <new_image_name>:<tag>
  

• Remove an image:

  docker rmi <image_id>
  

🔄 Container Management - View container logs:

• View container logs:

  docker logs <container_id>
  

• Access a running container (Interactive Shell):

  docker exec -it <container_id> /bin/bash
  

• Copy files from a container to the host:

  docker cp <container_id>:<path_in_container> <host_path>
  

🏗 Docker Networking - List networks:

• List networks:

  docker network ls
  

• Create a network:

  docker network create <network_name>
  

• Connect a running container to a network:

  docker network connect <network_name> <container_id>
  

🐳 Docker Compose - Start services in Detached mode:

• Start services in Detached mode:

  docker-compose up -d
  

• Stop services:

  docker-compose down
  

• Build and start containers:

  docker-compose up --build
  

📊 Inspection and Monitoring - View container details:

• View container details:

  docker inspect <container_id>
  

• Display resource usage (CPU, RAM):

  docker stats
  

🛠 Volumes - List volumes:

• List volumes:

  docker volume ls
  

• Create a volume:

  docker volume create <volume_name>
  

• Mount a volume (during docker run):

  docker run -v <volume_name>:<path_in_container> <image_name>
  

💡 Tip: Use docker system prune to remove unused containers, networks, and images.
