環境規劃：
·關閉防火牆和selinux
systemctl stop firewalld.service
systemctl disable firewalld.service
# vi /etc/sysconfig/selinux
SELINUX=disabled
# setenforce 0
服務端
1.安裝並啟動docker
yum -y install docker
service docker start
chkconfig docker on
2.拉取本地私有倉庫registry
[root@localhost ~]# docker pull registry
Trying to pull repository docker.io/registry ...

3.查看registry鏡像
[root@localhost ~]# docker images
docker.io/busybox latest 0064fda8c45d 5 days ago 1.113 MB
docker.io/registry latest 105c6c9299d9 5 days ago 423.3 MB
docker.io/CentOS latest ce20c473cd8a 6 days ago 172.3 MB
4.基於私有倉庫鏡像運行容器
默認情況下，會將倉庫存放於容器的/tmp/registry目錄下，這樣如果容器被刪除，則存放於容器中的鏡像也會丟失，所以我們一般情況下會指定本地一個目錄掛載到容器的/tmp/registry下， 兩個目錄下都有！
·registry的默認存儲路徑是/tmp/registry，只是個臨時目錄，一段時間之後就會消失
·所以使用-v參數，指定個本地持久的路徑，
[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
5.訪問私有倉庫
[root@localhost ~]# curl 127.0.0.1:5000/v1/search
{"num_results": 0, "query": "", "results": []} #私有倉庫為空，沒有提交新鏡像到倉庫中
6.從Docker HUB 上拉取一個鏡像測試
[root@localhost ~]#docker pull busybox
[root@localhost ~]#docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
docker.io/busybox latest 0064fda8c45d 5 days ago 1.113 MB
docker.io/registry latest 105c6c9299d9 5 days ago 423.3 MB
docker.io/centos latest ce20c473cd8a 6 days ago 172.3 MB
7.創建鏡像鏈接為基礎鏡像打個標簽
[root@localhost ~]# docker tag docker.io/busybox 192.168.0.167:5000/busybox
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
192.168.0.167:5000/busybox latest 0064fda8c45d 5 days ago 1.113 MB
docker.io/busybox latest 0064fda8c45d 5 days ago 1.113 MB
docker.io/registry latest 105c6c9299d9 5 days ago 423.3 MB
docker.io/centos latest ce20c473cd8a 6 days ago 172.3 MB
8.修改docker配置文件，指定私有倉庫url
[root@localhost ~]# vim /etc/sysconfig/docker
修改此行
OPTIONS='--insecure-registry 192.168.0.167:5000 '
[root@localhost ~]# service docker restart
9.上傳鏡像到本地私有倉庫
docker push 192.168.0.167:5000/busybox
10.查看私有倉庫是否有對應的鏡像
[root@localhost ~]# curl 192.168.0.167:5000/v1/search
{"num_results": 1, "query": "", "results": [{"description": "", "name": "library/busybox"}]}
11.查看鏡像的存儲目錄和文件
[root@localhost ~]# tree /opt/data/registry/repositories/
/opt/data/registry/repositories/
└── library
└── ssh
├── _index_images
├── json
├── tag_latest
└── taglatest_json
2 directories, 4 files
客戶端
1.安裝並啟動docker
yum -y install docker
service docker start
chkconfig docker on
2.修改docker配置文件，指定私有倉庫url
[root@localhost ~]# vim /etc/sysconfig/docker
修改此行
OPTIONS='--insecure-registry 192.168.0.167:5000 '
[root@localhost ~]# service docker restart
3.測試，下載剛才上傳的鏡像
[root@localhost ~]# docker pull 192.168.0.167:5000/busybox
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
192.168.0.167:5000/busybox latest 0064fda8c45d 5 days ago 1.113 MB
docker.io/registry latest 105c6c9299d9 5 days ago 423.3 MB
docker.io/centos latest ce20c473cd8a 6 days ago 172.3 MB
docker.io/atcol/docker-registry-ui latest d838355ad903 6 months ago 890.5 MB
