【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 NAME DESCRIPTION STARS OFFICIAL AUTOMATED centos DEPRECATED; The official build of CentOS. 7568 [OK] kasmweb/centos-7-desktop CentOS 7 desktop for Kasm Workspaces 36 couchbase/centos7-systemd centos7-systemd images with additional debug… 7 [OK] dokken/centos-7 CentOS 7 image for kitchen-dokken 6 dokken/centos-stream-9 4 dokken/centos-stream-8 4 continuumio/centos5_gcc5_base 3 eclipse/centos_jdk8 CentOS, JDK8, Maven 3, git, curl, nmap, mc, … 3 [OK] dokken/centos-8 CentOS 8 image for kitchen-dokken 3 adoptopenjdk/centos7_build_image 1 spack/centos7 CentOS 7 with Spack preinstalled 1 spack/centos6 CentOS 6 with Spack preinstalled 1 atlas/centos7-atlasos ATLAS CentOS 7 Software Development OS 0 couchbase/centos-72-java-sdk 0 ustclug/centos Official CentOS Image with USTC Mirror 0 couchbase/centos-72-jenkins-core 0 dokken/centos-6 CentOS 6 image for kitchen-dokken 0 datadog/centos-i386 0 couchbase/centos-70-sdk-build 0 couchbase/centos-69-sdk-build 0 couchbase/centos-69-sdk-nodevtoolset-build 0 bitnami/centos-extras-base 0 corpusops/centos-bare https://github.com/corpusops/docker-images/ 0 bitnami/centos-base-buildpack Centos base compilation image 0 [OK] corpusops/centos centos corpusops baseimage 0
查找超过10赞的镜像
[root@Docker-Ubu1804-p11:~]# docker search --filter=stars=10 centos NAME DESCRIPTION STARS OFFICIAL AUTOMATED centos DEPRECATED; The official build of CentOS. 7568 [OK] kasmweb/centos-7-desktop CentOS 7 desktop for Kasm Workspaces 36
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
[root@Docker-Ubu1804-p11:~]# docker images

四、镜像导出
1、docker save 命令
Usage: docker save [OPTIONS] IMAGE [IMAGE...] Save one or more images to a tar archive (streamed to STDOUT by default) Options: -o, --output string Write to a file, instead of STDOUT
#常用写法 docker save IMAGE1 IMAGE2 ... > /path/file.tar docker save -o /path/file.tar IMAGE1 IMAGE2 ...
将janzen项目的镜像导出 至 janzen_web_images.tar
[root@Docker-Ubu1804-p11:~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE janzen/app1 v3.0 f65a9531bfc7 17 hours ago 572MB janzen/nginx-centos7 1.20.1-v2.0 4919aacb5ea0 17 hours ago 562MB janzen/centos7 v1.0 b9d392225b3e 2 days ago 529MB busybox 1.36 7cfbbec8963d 5 weeks ago 4.86MB busybox 1.35.0 a711f05d3384 16 months ago 1.24MB busybox latest beae173ccac6 16 months ago 1.24MB nginx latest 605c77e624dd 16 months ago 141MB alpine latest c059bfaa849c 17 months ago 5.59MB ubuntu 18.04 5a214d77f5d7 19 months ago 63.1MB centos 7 eeb6ee3f44bd 19 months ago 204MB [root@Docker-Ubu1804-p11:~]# docker save janzen/app1:v3.0 janzen/nginx-centos7:1.20.1-v2.0 > janzen_web_images.tar [root@Docker-Ubu1804-p11:~]# ls disk.sh image.tar issue janzen_web_images.tar os.version redis_install.sh system_info.sh
将janzen项目镜像及基础镜像 导出 至 janzen_images.tar
[root@Docker-Ubu1804-p11:~]# docker save -o janzen_images.tar janzen/app1:v3.0 janzen/nginx-centos7:1.20.1-v2.0 janzen/centos7:v1.0 [root@Docker-Ubu1804-p11:~]# ls disk.sh image.tar issue janzen_images.tar janzen_web_images.tar os.version redis_install.sh system_info.sh
五、镜像导入
1、docker load 命令导入镜像数据
Usage: docker load [OPTIONS] Load an image from a tar archive or STDIN Options: -i, --input string Read from tar archive file, instead of STDIN -q, --quiet Suppress the load output
# 常用写法 docker load -i /path/imagefile docker load < /path/imagefile

将 busybox_image.tar 中的镜像导入本地
[root@Template-CentOS7-7 ~]# ls anaconda-ks.cfg busybox_image.tar docker docker-19.03.15.tgz janzen_images.tar [root@Template-CentOS7-7 ~]# docker load < busybox_image.tar 01fd6df81c8e: Loading layer [==================================================>] 1.459MB/1.459MB Loaded image: busybox:latest 6008d842465c: Loading layer [==================================================>] 1.463MB/1.463MB Loaded image: busybox:1.35.0 baacf561cfff: Loading layer [==================================================>] 5.092MB/5.092MB Loaded image: busybox:1.36 [root@Template-CentOS7-7 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE janzen/app1 v3.0 f65a9531bfc7 18 hours ago 572MB janzen/nginx-centos7 1.20.1-v2.0 4919aacb5ea0 18 hours ago 562MB janzen/centos7 v1.0 b9d392225b3e 2 days ago 529MB busybox 1.36 7cfbbec8963d 5 weeks ago 4.86MB busybox 1.35.0 a711f05d3384 16 months ago 1.24MB busybox latest beae173ccac6 16 months ago 1.24MB
六、删除镜像
1、docker rmi 删除镜像
Usage: docker rmi [OPTIONS] IMAGE [IMAGE...] docker image rm [OPTIONS] IMAGE [IMAGE...] Remove one or more images Options: -f, --force Force removal of the image --no-prune Do not delete untagged parents
删除镜像 busybox:latest
