一、准备
1、激活网卡
# vim /etc/sysconfig/network-scripts/ifcfg-ens160
修改此行
ONBOOT=
yes
# /etc/init.d/network restart
2、关闭本地防火墙并设置开机不自启动
# systemctl stop firewalld.service
# systemctl disable firewalld.service
3、关闭本地selinux防火墙
# vi /etc/sysconfig/selinux
SELINUX=disabled
# setenforce 0
4、安装ifconfig工具
# yum install net-tools
二、安装
1、安装docker
# yum install docker
# yum upgrade device-mapper-libs
# service docker start
# chkconfig docker on
2、本地私有仓库registry
[root@localhost ~]# docker pull registryTrying to pull repository docker.io/registry ... 24dd746e9b9f: Download complete 706766fe1019: Download complete a62a42e77c9c: Download complete 2c014f14d3d9: Download complete b7cf8f0d9e82: Download complete d0b170ebeeab: Download complete 171efc310edf: Download complete 522ed614b07a: Download complete 605ed9113b86: Download complete 22b93b23ebb9: Download complete 2ac557a88fda: Download complete 1f3b4c532640: Download complete 27ebaac643a7: Download complete ce630195cb45: Download complete Status: Downloaded newer p_w_picpath for docker.io/registry:latest [root@localhost ~]# docker p_w_picpaths REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE docker.io/registry latest 24dd746e9b9f 3 days ago 413.8 MB
3、基于私有仓库镜像运行容器
[root@CentOS7]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry docker.io/registry 511e67e1fa11d879f8c1f83a33fe94efc465598eec8f5e3a07cdc729b2e1d454 Usage of loopback devices is strongly discouraged for production use. Either use `--storage-opt dm.thinpooldev` or use `--storage-opt dm.no_warn_on_loop_devices=true` to suppress this warning. [root@CentOS7]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES cc4de7360d64 docker.io/registry:latest "docker-registry" 7 seconds ago Up 6 seconds 0.0.0.0:5000->5000/tcp sad_albattani
4、访问私有仓库
[root@localhost ~]# curl 127.0.0.1:5000/v1/search
{"num_results": 0, "query": "", "results": []} //私有仓库为空，没有提交新镜像到仓库中
5、从Docker Hub上下载一个ssh镜像
[root@localhost ~]# docker search -s 10 ssh NAME DESCRIPTION STARS OFFICIAL AUTOMATED docker.io: docker.io/fedora/ssh 18 [OK] [root@localhost ~]# docker pull fedora/ssh Trying to pull repository docker.io/fedora/ssh ... 2aeb2b6d9705: Download complete 511136ea3c5a: Download complete 00a0c78eeb6d: Download complete 834629358fe2: Download complete 571e8a51403c: Download complete 87d5d42e693c: Download complete 92b5ef05fe68: Download complete 92d3910dc33c: Download complete cf2e9fa11368: Download complete Status: Downloaded newer p_w_picpath for docker.io/fedora/ssh:latest [root@localhost ~]# docker p_w_picpaths REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE docker.io/registry latest 24dd746e9b9f 3 days ago 413.8 MB docker.io/fedora/ssh latest 2aeb2b6d9705 9 days ago 254.4 MB
6、创建镜像链接或为基础镜像打个标签
[root@localhost ~]# docker tag docker.io/fedora/ssh 127.0.0.1:5000/ssh [root@localhost ~]# docker p_w_picpaths REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE docker.io/registry latest 24dd746e9b9f 3 days ago 413.8 MB docker.io/fedora/ssh latest 2aeb2b6d9705 9 days ago 254.4 MB 127.0.0.1:5000/ssh latest 2aeb2b6d9705 9 days ago 254.4 MB
###############################################
docker commit <容器ID> name
docker tag <镜像ID> 172.20.135.90:5000/royal
docker push 172.20.135.90:5000/royal
###############################################
7、修改Docker配置文件制定私有仓库url
[root@localhost ~]# vim /etc/sysconfig/docker修改此行 OPTIONS='--selinux-enabled --insecure-registry 172.20.135.90:5000' [root@localhost ~]# service docker restart Redirecting to /bin/systemctl restart docker.service
8、提交镜像到本地私有仓库中
[root@localhost ~]# docker push 127.0.0.1:5000/ssh
The push refers to a repository [127.0.0.1:5000/ssh] (len: 1)
Sending p_w_picpath list
Pushing repository 127.0.0.1:5000/ssh (1 tags)
511136ea3c5a: Image successfully pushed
00a0c78eeb6d: Image successfully pushed
834629358fe2: Image successfully pushed
571e8a51403c: Image successfully pushed
87d5d42e693c: Image successfully pushed
92b5ef05fe68: Image successfully pushed
92d3910dc33c: Image successfully pushed
cf2e9fa11368: Image successfully pushed
2aeb2b6d9705: Image successfully pushed
Pushing tag for rev [2aeb2b6d9705] on {http://127.0.0.1:5000/v1/repositories/ssh/tags/latest}
9、查看私有仓库是否存在对应的镜像
[root@localhost ~]# curl 127.0.0.1:5000/v1/search{"num_results": 1, "query": "", "results": [{"description": "", "name": "library/ssh"}]}
10、查看镜像的存储目录和文件
[root@localhost ~]# tree /data/registry/repositories/ └── library └── ssh ├── _index_p_w_picpaths ├── json ├── tag_latest └── taglatest_json 2 directories, 4 files
三、从私有仓库中下载已有的镜像
1、登陆另外一台Docker客户端
2、修改Docker配置文件
[root@localhost ~]# vim /etc/sysconfig/docker
修改此行
OPTIONS=
'--selinux-enabled --insecure-registry 172.20.135.90:5000'
//
添加私有仓库地址
[root@localhost ~]
# service docker restart
Redirecting to
/bin/systemctl
restart docker.service
3、从私有仓库中下载已有的镜像
docker pull 172.20.135.90:5000/tom
四、浏览器访问仓库
浏览器输入：http://172.20.135.90:5000/

添加参数 -e GUNICORN_OPTS=["--preload"]
docker run -d -p 5000:5000 -v /data/registry:/tmp/registry -e GUNICORN_OPTS=["--preload"] docker.io/registry
