Docker环境上的一切操作都基于镜像之上的，所以我们先来了解下镜像的基本管理，简单管理是基于单镜像操作的。
显示本地镜像列表（等同于docker images）：docker image ls
[root@localhost ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE thehunt33r/docker-brimir latest b7bf3e5cd2cf 2 years ago 1.19GB
查询镜像：docker search nginx

下载镜像（等同于docker pull）：docker image pull nginx #不指定版本标签为直接下载latest最新版本（版本标签查询：hub.docker.com）
[root@localhost ~]# docker image pull nginx Using default tag: latest latest: Pulling from library/nginx 5e6ec7f28fb7: Pull complete ab804f9bbcbe: Pull complete 052b395f16bc: Pull complete Digest: sha256:56bcd35e8433343dbae0484ed5b740843dd8bff9479400990f251c13bbb94763 Status: Downloaded newer image for nginx:latest [root@localhost ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 42b4762643dc 7 days ago 109MB thehunt33r/docker-brimir latest b7bf3e5cd2cf 2 years ago 1.19GB
删除本地Docker镜像（等同于docker rmi）:docker image rm nginx
[root@localhost ~]# docker image rm nginx Untagged: nginx:latest Untagged: nginx@sha256:56bcd35e8433343dbae0484ed5b740843dd8bff9479400990f251c13bbb94763 Deleted: sha256:42b4762643dcc9bf492b08064b55fef64942f055f0da91289a8abf93c6d6b43c Deleted: sha256:e0e55dd2303b3e3ec852acae267d1f8a3eea27a22c64a5829304ecee4d3f559c Deleted: sha256:4062cf272cdd99e83b1c21f712e5e1359c91ecf92925e56c62133c3324b84e45 Deleted: sha256:3c816b4ead84066ec2cadec2b943993aaacc3fe35fcd77ada3d09dc4f3937313 [root@localhost ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE thehunt33r/docker-brimir latest b7bf3e5cd2cf 2 years ago 1.19GB
