1、使用registry镜像创建私有仓库
安装Docker后,可以通过官方提供的registry镜像来简单搭建一套本地私有仓库环境:
docker run -d -p 5000:5000 registry
这条命令将自动下载并启动一个registry容器,创建本地的私有仓库服务。默认会将仓库创建在容器的/tmp/registry目录下。可以通过-v参数来将镜像文件存放在本地指定路径
例如:将上传的镜像放到/opt/data/registry目录:
docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry
此时将在本地创建一个私有仓库服务,监听端口为5000。
2.管理私有仓库
docker本地私有仓库地址为10.0.0.32:5000
首先在客户端查看本地镜像:
[[email protected] ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu 16.04 20c44cd7596f 11 days ago 123MB ubuntu latest 20c44cd7596f 11 days ago 123MB centos latest d123f4e55e12 3 weeks ago 197MB [[email protected] ~]#
将镜像通过docker tag修改镜像标签为10.0.0.32:5000/test:
[[email protected] ~]# docker tag ubuntu:16.04 10.0.0.32:5000/test [[email protected] ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE 10.0.0.32:5000/test latest 20c44cd7596f 11 days ago 123MB ubuntu 16.04 20c44cd7596f 11 days ago 123MB ubuntu latest 20c44cd7596f 11 days ago 123MB centos latest d123f4e55e12 3 weeks ago 197MB [[email protected] ~]#
由于docker仓库与客户端的https问题,需要修改/usr/lib/systemd/system/docker.service文件,添加 ExecStart=/usr/bin/dockerd --registry-mirror=https://1y8rn456.mirror.aliyuncs.com --insecure-registry 10.0.0.32:5000之后需要重启docker。
使用docker push将镜像上传到私有仓库:
[[email protected] docker]# docker push 10.0.0.32:5000/test The push refers to a repository [10.0.0.32:5000/test] 2f5b0990636a: Pushed c9748fbf541d: Pushed b3968bc26fbd: Pushed aa4e47c45116: Pushed 788ce2310e2f: Pushed latest: digest: sha256:d4558f7616365813792918b6d73dc474bcacf99b13d1ed947731a653fb6e260c size: 1357
拉取私有仓库镜像:
[[email protected] docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE ubuntu 16.04 20c44cd7596f 11 days ago 123MB ubuntu latest 20c44cd7596f 11 days ago 123MB centos latest d123f4e55e12 3 weeks ago 197MB [[email protected] docker]# [[email protected] docker]# docker pull 10.0.0.32:5000/test Using default tag: latest latest: Pulling from test Digest: sha256:d4558f7616365813792918b6d73dc474bcacf99b13d1ed947731a653fb6e260c Status: Downloaded newer image for 10.0.0.32:5000/test:latest [[email protected] docker]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE 10.0.0.32:5000/test latest 20c44cd7596f 11 days ago 123MB ubuntu 16.04 20c44cd7596f 11 days ago 123MB ubuntu latest 20c44cd7596f 11 days ago 123MB centos latest d123f4e55e12 3 weeks ago 197MB [[email protected] docker]#
