docker simple tutorial (3) common operations

Before we start, let's understand the difference between images and containers:

• Mirroring: Just like the configuration files in the song, such as the index.html file we wrote, Dockerfile, etc. A mirror can create multiple containers. For example, if we have a configuration file, we can run multiple containers with docker run based on this configuration file.
• Container: The container represents the instance we are running, such as the basic website we created in the previous section to run a service. He includes start, stop, delete, pause, etc.

1: View a list of all containers: docker ps -a

docker ps -a

2: View the list of running containers: docker ps

docker ps

3: Run the container: docker run

docker run

If you forget, you can refer to the previous section.

4: Stop the container: docker stop

docker stop <container id>

Use docker psto view all containers and find the corresponding id

For example, a helloworld container we created in the previous section:

Then we can execute docker stop 2bbfd11bff2ato shut down the container.

5: Delete the stopped container: docker rm

docker rm <container id>

6: Rename the container: docker rename

docker rename <old_container_id> <new_container_name>

7: Download image: docker pull

docker pull <image name>

like:docker pull nginx

More image files can be downloaded from the docker hub repository

8: View the mirror list: docker images

docker images

9: View image details: docker inspect

docker inspect <image name_or_id>

like:docker inspect helloworld

10: Delete the image: docker rmi

docker rmi <image name_or_id>

11: Build the image: docker build

docker build

If you forget the specific parameters, you can refer to the construction process in the previous section first, which will be introduced in detail later.
