從鏡像倉(cāng)庫(kù)查詢鏡像
Docker Hub 的地址是：hub.docker.com/
鏡像倉(cāng)庫(kù)搜索結(jié)果.png
在 Docker Hub 的搜索結(jié)果中狼荞，有幾項(xiàng)關(guān)鍵的信息有助于我們選擇合適的鏡像：
OFFICIAL 代表鏡像為 Docker 官方提供和維護(hù)，相對(duì)來(lái)說(shuō)穩(wěn)定性和安全性較高
Stars 代表鏡像的關(guān)注人數(shù)篡腌，這類(lèi)似 GitHub 的 Stars答恶，可以理解為熱度
Downloads 代表鏡像被拉取的次數(shù)，基本上能夠表示鏡像被使用的頻度
除了直接通過(guò) Docker Hub 網(wǎng)站搜索鏡像這種方式外，我們還可以用 docker CLI 中的 docker search 這個(gè)命令搜索 Docker Hub 中的鏡像。
docker search mysql
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker search mysql

管理鏡像
除了使用docker images查看鏡像列表以外 還可以使用 docker inspect （容器ID或鏡像ID） 查看鏡像詳情
docker inspect mysql/990386cbd5c0
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker inspect mysql
[
{
"Id": "sha256:990386cbd5c04effd6669ab958aa41ce06052bbe52b8d88f259bfadf9fbf37c9",

刪除鏡像
docker rmi （鏡像ID或名稱(chēng)） 支持同時(shí)刪除多個(gè)鏡像
[root@iZ2ze3gye2rcpntgyzryzbZ ~]# docker rmi ubuntu
