docker-5 docker仓库

Posted 2020-08-19

docker部署环境：CentOS release 6.5 (Final)

1、编辑docker的配置文件,因为我们启动的registry服务不是安全可信赖的。所以我们需要修改docker的配置文件，

[[email protected]]# vim /etc/sysconfig/docker

other_args="--insecure-registry=192.168.1.243:5000 -H tcp://0.0.0.0:235 -H unix:///var/run/docker.sock"

2、修改好配置文件之后，重启docker

[[email protected]]# /etc/init.d/docker restart

3、获取registry

[[email protected]]# docker pull registry

4、启动registry

[[email protected]]# docker run -d -p 5000:5000 -v /opt/data/registry:/var/lib/registry registry

[[email protected]]# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0e600f830f51 registry "/entrypoint.sh /etc 13 minutes ago Up 2 seconds 0.0.0.0:5000->5000/tcp drunk_albattani

Registry服务默认会将上传的镜像保存在容器的/var/lib/registry，我们将主机的/opt/registry目录挂载到该目录，即可实现将镜像保存到主机的/opt/registry目录了。

这时在浏览器里面输入：http://IP:5000/v2/

会返回一个{}

5、做tag标签

[[email protected] ROOT]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
pt/tomcat_biz       v1                  f56c998ac2f3        37 hours ago        756.3 MB
centos              latest              97cad5e16cb6        6 days ago          196.5 MB
registry            latest              5c929a8b587a        3 weeks ago         33.27 MB
[[email protected] ROOT]# docker tag centos:latest 10.116.208.166:5000/test/centos:v1     
[[email protected] ROOT]# docker images
REPOSITORY                        TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
pt/tomcat_biz                     v1                  f56c998ac2f3        37 hours ago        756.3 MB
centos                            latest              97cad5e16cb6        6 days ago          196.5 MB
10.116.208.166:5000/test/centos   v1                  97cad5e16cb6        6 days ago          196.5 MB
registry                          latest              5c929a8b587a        3 weeks ago         33.27 MB

6、push到registry

[[email protected] ROOT]# docker push 10.116.208.166:5000/test/centos:v1
The push refers to a repository [10.116.208.166:5000/test/centos] (len: 1)
97cad5e16cb6: Image already exists 
05fe84bf6d3f: Image already exists 
af0819ed1fac: Image successfully pushed 
3690474eb5b4: Image already exists 
Digest: sha256:31879c6c05e2cb19300a12a685998f4d45f924f48a7d7d215846c9511f40176c

7、打开另外一台服务器，做pull测试

[[email protected] ROOT]# docker push 10.116.208.166:5000/test/centos:v1

到此为止，私有的仓库就搭建好了。
