Docker笔记-搭建私有仓库

Docker笔记-搭建私有仓库

1、下载一个docker官方私有仓库镜像

[root@zsx ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
619be1103602: Pull complete
5daf2fb85fb9: Pull complete
ca5f23059090: Pull complete
8f2a82336004: Pull complete
68c26f40ad80: Pull complete
Digest: sha256:fb9c9aef62af3955f6014613456551c92e88a67dcf1fc51f5f91bcbd1832813f
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest

2、运行一个docker私有容器仓库

# -d:后台运行 
# -p:端口映射,宿主机的5000:容器内的5000
# -v:数据卷挂载,宿主机的/opt/data/registry:/var/lib/registry 
# registry:镜像名
# /var/lib/registry:存放私有仓库位置
[root@zsx ~]# docker run -d -p 5000:5000 -v /opt/data/registry:/var/lib/registry  registry
90d868fb5b9862962381780c8ce41917cf23eb626aade91c1c79e050a9152578

[root@zsx ~]# docker ps
CONTAINER ID   IMAGE                    COMMAND                  CREATED          STATUS          PORTS                                                                                      NAMES
90d868fb5b98   registry                 "/entrypoint.sh /etc…"   18 seconds ago   Up 17 seconds   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp                                                  pedantic_torvalds

3、修改docker的配置文件

Docker 默认不允许非 HTTPS 方式推送镜像，我们可以通过 Docker 的配置选项来取消这个限制。

修改docker的配置文件，让他支持http方式，上传私有镜像。

# 写入如下内容
[root@zsx ~]# vim /etc/docker/daemon.json
{"registry-mirrors":["https://reg-mirror.qiniu.com/"],"insecure-registries":["192.168.60.195:5000"]
}

4、修改docker的服务配置文件

[root@zsx ~]# vim /lib/systemd/system/docker.service
# 找到[service]这一代码区域块,写入如下参数
[Service]
EnvironmentFile=-/etc/docker/daemon.json

5、重新加载docker服务

[root@zsx ~]# systemctl daemon-reload

6、重启docker服务

# 注意:重启docker服务,所有的容器都会挂掉
[root@zsx ~]# systemctl restart docker

# 重新启动
[root@zsx ~]# docker start 90d868fb5b98
90d868fb5b98

7、修改本地镜像的tag标记,往自己的私有仓库推送

# 查看仓库中的镜像
[root@zsx ~]# curl http://192.168.60.195:5000/v2/_catalog
{"repositories":[]}

[root@zsx ~]# docker images
REPOSITORY                                       TAG                IMAGE ID       CREATED         SIZE
registry                                         latest             9363667f8aec   29 hours ago    25.4MB
springboot/spring-boot-docker                    latest             b3bb84d4545a   7 weeks ago     542MB

[root@zsx ~]# docker images
REPOSITORY                                       TAG                IMAGE ID       CREATED         SIZE
registry                                         latest             9363667f8aec   29 hours ago    25.4MB
192.168.60.195:5000/spring-boot-docker           latest             b3bb84d4545a   7 weeks ago     542MB

[root@zsx ~]# docker push 192.168.60.195:5000/spring-boot-docker
Using default tag: latest
The push refers to repository [192.168.60.195:5000/spring-boot-docker]

# 查看仓库中的镜像
[root@zsx ~]# curl http://192.168.60.195:5000/v2/_catalog
{"repositories":["spring-boot-docker"]}

8、下载私有仓库的镜像

# 如果是其他机器拉取,需要配置"insecure-registries":["192.168.60.195:5000"]
[root@zsx ~]# docker pull 192.168.60.195:5000/spring-boot-docker
Using default tag: latest
latest: Pulling from spring-boot-docker
001c52e26ad5: Pull complete

Status: Downloaded newer image for 192.168.60.195:5000/spring-boot-docker:latest
192.168.60.195:5000/spring-boot-docker:latest

9、Docker Registry WebUI 工具

使用WebUI工具管理镜像会更方便，可以直观地看到registry 中的资源情况。

Docker Registry WebUI 工具：docker-registry-web

# 下载docker-registry-web镜像
[root@zsx ~]# docker pull hyper/docker-registry-web
Using default tag: latest
latest: Pulling from hyper/docker-registry-web
Digest: sha256:723ffa29aed2c51417d8bd32ac93a1cd0e7ef857a0099c1e1d7593c09f7910ae
Status: Image is up to date for hyper/docker-registry-web:latest
docker.io/hyper/docker-registry-web:latest

# 启动registry-web
[root@zsx ~]# docker run -d -p 8090:8080 --name registry-web --link pedantic_torvalds -e REGISTRY_URL=http://192.168.60.195:5000/v2 -e REGISTRY_NAME=192.168.60.195:5000 hyper/docker-registry-web
db6b26bac50bdb2cd9aa5b186fa8e6cc042b39cd9e0d8d9877587febe32af8ab

访问web界面，浏览器输入192.168.60.195:8090，即可查看registry仓库中的镜像信息。
