Container related orders :
1. Create a container
Create a container :docker run -it --name=c1 centos:7 /bin/bash
Parameters -i Indicates that the container is always running ,-t Means to assign a terminal , After creation , By the way, I logged in to the container , When ssh Exit time , The container will close
docker run -id --name=c2 centos:7
Parameters -d Means running in the background , After creation , Will not enter the container , adopt ssh After entering the container , Exit the container , The container will not close
Parameters :
-i: Keep the container running , Usually with -t Use at the same time . Join in it this 2 After a parameter , The container automatically enters the container after it is created , After exiting the container , The container closes automatically
-t: Reassign a pseudo input terminal to the container , Usually with -i Use at the same time
-d: To guard ( backstage ) Mode running container . Create a container to run in the background , Need to use docker exec Into the container . after , The container will not close
-it: The container you create is generally called an interactive container ,-id The container you create is generally called a guard container
--name: Name the container you created
2. Look at the container
docker ps: View the running container
docker ps -a# View all containers
3. Into the container :
docker exec Parameters # Exit the container , The container will not close
docker exec -it c2 /bin/bash
4. Start the container
docker start Container name
docker start c2
5. Closed container
docker stop Container name
docker stop c2
6. Delete container
If the container is running, the deletion fails , You need to stop the container to delete
docker rm c2
Delete all containers
docker rm `docker ps -aq`
7. View container information
docker inspect Container name
docker inspect c2
Data volume of container
Data volume :
- . Is a directory or file in the host
- When the container directory and the data volume directory are bound , The other party's changes will be synchronized immediately
- A data volume can be mounted by multiple containers at the same time
- Multiple data volumes can also be mounted at the same time
Configure data volume :
When you create a startup container , Use -v Parameters Set up the data volume
docker run ... -v Host directory file : Directory file in container ...
matters needing attention :
1. Directory must be an absolute path
2. If the directory does not exist , Automatically created
3. You can mount multiple data volumes
Example :docker run -it --name=c1 -v /root/data:/root/data_contailnet centos:7 /bin/bash
Configure the data volume container :
1. Create a start c3 Data volume container , Use -v Parameter setting data volume
docket run -it --name=3 -volumes centos:7 /bin/sh
2. Create a start c1 c2 Containers , Use --volumes-from Parameter setting data volume
docker run -it --name=c1 --volumes-from c3 centos:7 /bin/bash
docker run -it --name=c2 --volumes-form c3 centos:7 /bin/bash
