1、docker version 查看当前docker ce版本

[root@iZbp14ak3swm571msqxpohZ ~]# docker version Client: Docker Engine - Community Version: 20.10.0 API version: 1.40 Go version: go1.13.15 Git commit: 7287ab3 Built: Tue Dec 8 18:57:35 2020 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 19.03.14 API version: 1.40 (minimum version 1.12) Go version: go1.13.15 Git commit: 5eb3275d40 Built: Tue Dec 1 19:19:17 2020 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.2.6 GitCommit: 894b81a4b802e4eb2a91d1ce216b8817763c29fb runc: Version: 1.0.0-rc8 GitCommit: 425e105d5a03fabd737a126ad93d62a9eeede87f docker-init: Version: 0.18.0 GitCommit: fec3683 [root@iZbp14ak3swm571msqxpohZ ~]# 

2、docker images 查看系统镜像

[root@iZbp14ak3swm571msqxpohZ ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE redis latest 6060df96cef3 3 months ago 104MB nginx latest f6d0b4767a6c 4 months ago 133MB mysql 5.7 697daaecf703 5 months ago 448MB centos latest 300e315adb2f 5 months ago 209MB java 8 d23bdf5b1b1b 4 years ago 643MB 

3、查看正在运行的容器

[root@iZbp14ak3swm571msqxpohZ ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 88d61b3ad7b9 nginx "/docker-entrypoint.…" 7 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp my-nginx 11b5dbd336c8 mysql:5.7 "docker-entrypoint.s…" 3 months ago Up 3 months 0.0.0.0:3306->3306/tcp, 33060/tcp mysql 

4、docker pull 获取镜像

[root@iZbp14ak3swm571msqxpohZ ~]# docker pull hello-world Using default tag: latest latest: Pulling from library/hello-world b8dfde127a29: Pull complete Digest: sha256:5122f6204b6a3596e048758cabba3c46b1c937a46b5be6225b835d091b90e46c Status: Downloaded newer image for hello-world:latest docker.io/library/hello-world:latest 

5、docker run 镜像名称，启动该镜像

[root@iZbp14ak3swm571msqxpohZ ~]# docker run hello-world Hello from Docker! This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/ 

6、docker rm 删除容器

[root@iZbp14ak3swm571msqxpohZ ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 95fff9c6e1ab hello-world "/hello" 46 seconds ago Exited (0) 45 seconds ago busy_heyrovsky 88d61b3ad7b9 nginx "/docker-entrypoint.…" 7 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp my-nginx 11b5dbd336c8 mysql:5.7 "docker-entrypoint.s…" 3 months ago Up 3 months 0.0.0.0:3306->3306/tcp, 33060/tcp mysql [root@iZbp14ak3swm571msqxpohZ ~]# docker rm 95fff9c6e1ab 95fff9c6e1ab [root@iZbp14ak3swm571msqxpohZ ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 88d61b3ad7b9 nginx "/docker-entrypoint.…" 7 weeks ago Up 2 weeks 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp my-nginx 11b5dbd336c8 mysql:5.7 "docker-entrypoint.s…" 3 months ago Up 3 months 0.0.0.0:3306->3306/tcp, 33060/tcp mysql 

7、docker rmi 镜像id或者镜像名称，删除镜像

[root@iZbp14ak3swm571msqxpohZ ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest d1165f221234 2 months ago 13.3kB redis latest 6060df96cef3 3 months ago 104MB nginx latest f6d0b4767a6c 4 months ago 133MB mysql 5.7 697daaecf703 5 months ago 448MB centos latest 300e315adb2f 5 months ago 209MB java 8 d23bdf5b1b1b 4 years ago 643MB [root@iZbp14ak3swm571msqxpohZ ~]# docker rmi d1165f221234 Untagged: hello-world:latest Untagged: hello-world@sha256:5122f6204b6a3596e048758cabba3c46b1c937a46b5be6225b835d091b90e46c Deleted: sha256:d1165f2212346b2bab48cb01c1e39ee8ad1be46b87873d9ca7a4e434980a7726 Deleted: sha256:f22b99068db93900abe17f7f5e09ec775c2826ecfe9db961fea68293744144bd [root@iZbp14ak3swm571msqxpohZ ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE redis latest 6060df96cef3 3 months ago 104MB nginx latest f6d0b4767a6c 4 months ago 133MB mysql 5.7 697daaecf703 5 months ago 448MB centos latest 300e315adb2f 5 months ago 209MB java 8 d23bdf5b1b1b 4 years ago 643MB
