Docker镜像的基本管理

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

[root@localhost ~]# docker search nginx
