一、Docker 常用命令

docker version 命令

[root@docker ~]# docker version

Client: Docker Engine - Community
 Version:           19.03.4
 API version:       1.40
 Go version:        go1.12.10
 Git commit:        9013bf583a
 Built:             Fri Oct 18 15:52:22 2019
 OS/Arch:           linux/amd64
 Experimental:      false
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

可以看到此处只有 Docker Client 的版本信息，同时显示 Cannot connect to the Docker daemon（Docker Server端）

那么将 Docker 服务启动起来，再次查看 Docker 版本：

[root@docker ~]# systemctl start docker

将 Docker 服务设置为开机自启动：

[root@docker ~]# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

选镜像的建议：
1. 优先考虑官方
2. stars 数量多

获取镜像：docker pull 镜像名

镜像加速器：阿里云加速器，daocloud加速器，中科大加速器，Docker中国官方镜像加速（https://registry.docker-cn.com）

docker pull centos:6.8 （没有指定版本，默认会下载最新版）
docker pull daocloud.io/huangzhichong/alpine-cn:latest

[root@docker ~]# docker pull nginx:1.16.0
1.16.0: Pulling from library/nginx
9fc222b64b0a: Pull complete 
30e9fc7d9c5b: Pull complete 
4b3a8aeaa40e: Pull complete 
Digest: sha256:3e373fd5b8d41baeddc24be311c5c6929425c04cabf893b874ac09b72a798010
Status: Downloaded newer image for nginx:1.16.0
docker.io/library/nginx:1.16.0

[root@docker ~]# docker images
REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
nginx                                 1.16.0              ae893c58d83f        2 months ago        109MB

查看镜像：docker images 或 docker image ls

查看已拉取下来的 Docker 镜像，有两种方法：

[root@docker ~]# docker image ls
REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
nginx                                 1.16.0              ae893c58d83f        2 months ago        109MB

[root@docker ~]# docker images
REPOSITORY                            TAG                 IMAGE ID            CREATED             SIZE
nginx                                 1.16.0              ae893c58d83f        2 months ago        109MB

删除镜像：docker rmi 或 docker image rm

例如：docker image rm centos:latest

[root@docker ~]# docker rmi nginx:1.16.0
Untagged: nginx:1.16.0
Untagged: nginx@sha256:3e373fd5b8d41baeddc24be311c5c6929425c04cabf893b874ac09b72a798010

或者

[root@docker ~]# docker image rm nginx:1.16.0
Untagged: nginx:1.16.0
Untagged: nginx@sha256:3e373fd5b8d41baeddc24be311c5c6929425c04cabf893b874ac09b72a798010
