关于docker:Docker进阶

1、镜像治理命令

1、查看以后的镜像
[root@node1 wordpress]# docker images
REPOSITORY     TAG            IMAGE ID       CREATED         SIZE
nginx          v1             a80567189207   6 days ago      141MB
bjbfd/nginx    latest         605c77e624dd   17 months ago   141MB
bjbfd/nginx    v1             605c77e624dd   17 months ago   141MB
nginx          latest         605c77e624dd   17 months ago   141MB
wordpress      latest         c3c92cc3dcb1   17 months ago   616MB

3、下载镜像 (新增)

4、查看镜像列表 (列表查问)
docker images 等同 docker image ls
[root@node1 wordpress]# docker image ls
REPOSITORY     TAG            IMAGE ID       CREATED         SIZE
