    * `docker stop my_container` - Stops the specified container.
        
    * `docker start my_container` - Starts a previously stopped container.
        
    * `docker restart my_container` - Restarts a container.
        
* **Listing Containers**
    
    * `docker ps` - Lists all currently running containers.
        
    * `docker ps -a` - Lists all containers, including those that are stopped.
        

#### **Image Management**

* **Fetching an Image from a Registry**
    
    * `docker pull ubuntu`\- Retrieves the `ubuntu` image from the Docker Hub or other specified registry.
        
* **Building an Image from a Dockerfile**
    
    * `docker build -t my_image .`\- Builds an image named `my_image` from a Dockerfile in the current directory.

    * `docker images` - Lists all local Docker images.
        
    * `docker rmi my_image` - Removes the specified image from the local system.
        

#### **Container Operations**

* **Interacting with Containers**
    
    * `docker exec -it my_container bash` - Executes a command (`bash` in this case) inside a running container.
        
    * `docker attach my_container` - Attaches to a running container for interaction.
        
    * `docker logs my_container` - Displays logs from the specified container.
        
* **Managing Container Resources**
    
    * `docker cp file.txt my_container:/path/to/destination` - Copies files between a container and the host system.
        
    * `docker pause my_container` and `docker unpause my_container` - Pauses or unpauses a running container.
        
    * `docker inspect my_container` - Displays detailed information about a specific container.
        

#### **Networking**

* **Network Management**
    
    * `docker network ls` - Lists all networks available on the Docker host.
        
    * `docker network create my_network` - Creates a new network.
        
    * `docker network connect my_network my_container` and `docker network disconnect my_network my_container` - Connects or disconnects a container from a network.
        

#### **Volume Management**

* **Volume Commands**
    
    * `docker volume ls` - Lists all Docker volumes.
        
    * `docker volume create my_volume` - Creates a new volume named `my_volume`.
