·
一、准备
地址规划：
Docker私有仓库地址：192.168.0.109
Docker客户端地址：192.168.0.110
|
1、激活网卡
# vi /etc/sysconfig/network-scripts/ifcfg-eno16777728
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 registry
Trying to pull repository docker.io
/registry

# docker images

3、基于私有仓库镜像运行容器
[root@localhost ~]
# docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry docker.io/registry
bb2c0d442df94e281479332c2608ef144f378e71743c5410e36b80c465771a95
[root@localhost ~]
# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
bb2c0d442df9 docker.io
/registry
:latest
"docker-registry"
10 seconds ago Up 7 seconds 0.0.0.0:5000->5000
/tcp
serene_hopper
|
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

:latest
[root@localhost ~]
# docker images

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 images
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
|
7、修改Docker配置文件制定私有仓库url
[root@localhost ~]
# vi /etc/sysconfig/docker
修改此行
OPTIONS=
'--selinux-enabled --insecure-registry 192.168.0.109:5000'
[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 image 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 /opt/data/registry/repositories/
/opt/data/registry/repositories/
└── library
└──
ssh
├── _index_images
├── 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
[root@localhost ~]
# ssh root@192.168.0.110
The authenticity of host
'192.168.0.110 (192.168.0.110)'
can't be established.
ECDSA key fingerprint is 5b:81:4b:66:d6:
dd
:48:16:9f:85:58:72:21:bd:ba:39.
Are you sure you want to
continue
connecting (
yes
/no
)?
yes
Warning: Permanently added
'192.168.0.110'
(ECDSA) to the list of known hosts.
root@192.168.0.110's password:
Last login: Sun Apr 26 14:39:51 2015 from 192.168.0.103
|
2、修改Docker配置文件
[root@localhost ~]
# vi /etc/sysconfig/docker
修改此行
OPTIONS=
'--selinux-enabled --insecure-registry 192.168.0.109:5000'
//
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
[root@localhost ~]
# docker pull 192.168.0.109:5000/ssh
Trying to pull repository 192.168.0.109:5000
/ssh
...

Status: Downloaded newer image
for

/ssh

[root@localhost ~]
# docker images
