docker日常管理

 

 

1.删除镜像
docker images
docker rmi bf756fb1ae65 ##镜像id

 

2.停掉docker容器
docker ps -a
docker stop f8397131982c

 

3.删除容器

docker ps -a
docker rm 1a18447e378b

或者是直接找出后删除
docker rm -f `docker ps -a -q`

 

4.docker重启某个镜像
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e18cf4366179 percona/pmm-server:2 "/opt/entrypoint.sh" 3 hours ago Exited (0) 5 minutes ago pmm-server
cb94c09505a3 percona/pmm-server:2 "/bin/true" 3 hours ago Created pmm-data
[root@localhost ~]# docker restart e18cf4366179

 

5.登录容器
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e18cf4366179 percona/pmm-server:2 "/opt/entrypoint.sh" 3 hours ago Up 10 minutes (healthy) 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp pmm-server

[root@localhost ~]#docker exec -ti pmm-server /bin/bash

 

 6.查看停掉的容器

docker ps -a --filter "status=exited" -q

 

 

 

7.拉取镜像
docker pull registry.cn-shenzhen.aliyuncs.com/gondor/milvus:v2.4.6
docker pull registry.cn-shenzhen.aliyuncs.com/gondor/attu:v2.4.6

 

 

8.保存镜像到本地

[root@host134 2.4.6]# docker images

docker save -o /soft/milvus/2.4.6/milvus2.4.6.tar.gz 636269526977
docker save -o /soft/milvus/2.4.6/attu2.4.6.tar.gz 3d15903f4290

 

9.删除镜像

docker rmi $(docker images -q)

 

10.查看latest镜像的版本

docker image inspect registry.cn-shenzhen.aliyuncs.com/gondor/postgres:latest|grep -i version

 

11.加载镜像

docker load -i milvus2.4.6.tar.gz

 

12.多个tag的镜像删除其中一个

[root@master soft]# docker images

docker rmi registry.cn-shenzhen.aliyuncs.com/hxlk8s/milvus-operator:v1.1.2

 

13.查看镜像信息

比如查看暴露的端口号

[root@node2 kafka-ui]# docker images
REPOSITORY                                               TAG       IMAGE ID       CREATED        SIZE

registry.cn-shenzhen.aliyuncs.com/hxlk8s/kafka-ui        v0.7.2    99307ab28a49   8 months ago   291MB
[root@node2 kafka-ui]# docker inspect 99307ab28a49

            "ExposedPorts": {
                "8080/tcp": {}
            },
