What are the built-in commands of docker

With the help of Docker, we can quickly deliver, test and deploy code, which can greatly reduce the time of deploying code. The characteristic of docker is that there are many commands, which is inconvenient for beginners to use.

The following is a summary of commonly used commands.

1. Mirror related commands

docker search 镜像名

Search for mirror

docker pull 仓库名

Download mirror

docker pull [选项] [Docker Registry地址]<仓库名>:<标签>

# The option can be done through docker pull – help View

# Docker Registry address: [:Port number], the default address is Docker Hub

# Warehouse name: The warehouse name is a two-part name, both < ;User name>/. For Docker Hub, if the user name is not given, the default is library, which is the official image

#Example:

[root@node1 docker]# docker pull mysql:5.7.19

docker images

List existing local images

docker build [选项] <上下文路径>

Build a new image based on the given Dockerfile file

Note: The name of the Dockerfile file can be named by yourself. If the file name is not "Dockerfile", the file name needs to be written in the build command

# Example

In the /home/docker/java/ruiyi01 directory, run the command: (The following dot indicates searching for the Dockfile file in the current directory)

docker build -t ruoyi-demo .

docker rmi <镜像id>

Delete the image

docker push 镜像名

Share the local image to the docker remote warehouse (this is for the default Docker Hub)

Note: Directly executing push will report an error. Use the docker tag command to rename the image to be shared (add an identifier)

For example, docker tag getting-started YOUR-USER-NAME/getting-started

Then execute push

docker push YOUR-USER-NAME/getting-started

2. Container-related commands

docker run [选项] 镜像名

Creating a new container and running it

# is equivalent to performing two steps: putting the image into the container (docker create), and then start the container to turn it into a runtime container (docker start)

# Example:

docker run -d --name ruoyi-demo-run -p 8083:8084 ruoyi-demo

(Based on the image ruoyi-demo, create a name in the background Run the ruoyi-demo-run container. The port numbers of the host and container are 8083 and 8084 respectively)

docker run -d --name vue-demo-run -p 8088:80 vue-demo

# -d Run in the background

# --name Name the container

# -p host port: container internal port

docker ps

View currently running container information

docker ps -a

View all containers

docker rm <容器id>

Delete a container .

Note: If it is running, it cannot be deleted directly. You need to stop running it first.

If you want to forcefully delete a running container, add the "force" flag to the command: for example

docker rm -f

docker rm $(docker ps -qa)

Delete all stopped containers

dockers exec -it <容器id/容器名>

Enter the container (new Terminal)

docker attach <容器id/容器名>

Enter the container

docker start 容器id

Run a container

docker stop 容器id

Stop a running container.

docker restart 容器id

Restart a running container

docker logs <容器id>

Get the running log of the container

docker commit

# Similar to the git commit operation

docker commit -m= "Submission description message" -a="Author" Container id Target image name: [Version message]

# Function: Submit the container we have operated into a new image through commit. We can use this modified image directly in the future.
