【Docker】镜像管理
一、搜索镜像
1、在官方网站搜索镜像
Docker 官方镜像仓库：https://hub.docker.com/
2、docker search 搜索镜像
Usage: docker search [OPTIONS] TERM Search the Docker Hub for images Options:
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print search using a Go template
--limit int Max number of search results (default 25)
--no-trunc Don't truncate output
OFFICIAL 官方镜像
AUTOMATED 使用第三方docker服务来编译镜像，可以在互联网上直接拉取到的镜像，减少了繁琐的编译过程
[root@Docker-Ubu1804-p11:~]# docker search centos

二、下载镜像
1、docker pull 下载镜像
Usage: docker pull [OPTIONS] NAME[:TAG|@DIGEST] Pull an image or a repository from a registry Options:
-a, --all-tags Download all tagged images in the repository
--disable-content-trust Skip image verification (default true)
--platform string Set platform if server is multi-platform capable
-q, --quiet Suppress verbose output
NAME 镜像名称，通常格式为 仓库服务器地址：端口号/项目名称或作者/镜像名称
:TAG 镜像版本号，如不指定，默认为 latest,即下载最新版本
@DISGEST 镜像摘要信息，较少使用，需要提前查询
下载最新版busybox镜像
[root@Docker-Ubu1804-p11:~]# docker pull busybox
Using default tag: latest #使用默认版本号：latest
latest: Pulling from library/busybox
5cc84ad355aa: Pull complete
Digest: sha256:5acba83a746c7608ed544dc1533b87c737a0b0fb730301639a0179f9344b1678 #镜像 DISGEST 摘要信息
Status: Downloaded newer image for busybox:latest
docker.io/library/busybox:latest #镜像完成下载路径
下载指定版本busybox
对应镜像的可用版本信息可在镜像仓库中 TAG 下查看
[root@Docker-Ubu1804-p11:~]# docker pull busybox:1.36
1.36: Pulling from library/busybox
4b35f584bb4f: Pull complete
Digest: sha256:b5d6fe0712636ceb7430189de28819e195e8966372edfc2d9409d79402a0dc16
Status: Downloaded newer image for busybox:1.36
docker.io/library/busybox:1.36
[root@Docker-Ubu1804-p11:~]#
指定下载源下载1.35.0版本 busybox
[root@Docker-Ubu1804-p11:~]# docker pull docker.io/library/busybox:1.35.0
1.35.0: Pulling from library/busybox
f643e116a03d: Pull complete
Digest: sha256:130df6999605f982ec67e5bee29d3a52614a075e949490f0a41702ee1dd98f3f
Status: Downloaded newer image for busybox:1.35.0
docker.io/library/busybox:1.35.0
[root@Docker-Ubu1804-p11:~]#
通过Digest下载mysql镜像
[root@Docker-Ubu1804-p11:~]# docker pull mysql@sha256:b45a7c3e6fb15526e8bf62ebb940cd460617e36f46155b8514fd9c9388231817
2、镜像下载存放目录
镜像默认下载存放目录：/var/lib/docker/overlay2/<镜像ID>
三、查看本地镜像
1、docker images 可查看本地镜像信息
[root@Docker-Ubu1804-p11:~]# docker images --help Usage: docker images [OPTIONS] [REPOSITORY[:TAG]] List images Options:
-a, --all Show all images (default hides intermediate images)
--digests Show digests
-f, --filter filter Filter output based on conditions provided
--format string Pretty-print images using a Go template
--no-trunc Don't truncate output
-q, --quiet Only show numeric IDs
##docker images 与 docker image ls 结果相同
#REPOSITORY 镜像所属仓库名称
#TAG 镜像版本号（标识，默认latest）
#IMAGE ID 镜像ID，如果镜像ID相同说明本质上是同一镜像
#CREATED 镜像创建时间
#SIZE 镜像大小
