docker 创建私有镜像之 registry

一、下载 registry 镜像

[root@localhost ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
c87736221ed0: Pull complete
1cc8e0bb44df: Pull complete
54d33bcb37f5: Pull complete
e8afc091c171: Pull complete
b4541f6d3db6: Pull complete
Digest: sha256:f87f2b82b4873e0651f928dcde9556008314543bd863b3f7e5e8d03b04e117f7
Status: Downloaded newer image for

二、创建镜像存储目录

[root@localhost ~]# mkdir

三、创建镜像容器

[root@localhost ~]# docker run -itd -v /data/registry:/var/lib/registry -p 80:5000name registry registry
e630985b09af4dedcf81a8dcb80202e591fefefc0a86e8328be70ce0643ab399#检查容器是否创建成功
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
e630985b09af registry "/entrypoint.sh /etc…" 23 seconds ago Up 22 seconds 0.0.0.0:80->5000/tcp registry#检查容器运行是否正常，如下显示说明运行正常
[root@localhost ~]# curl http://127.0.0.1/v2/_catalog
{"repositories":[]}

四、修改daemon.json文件，修改为如下内容

[root@localhost ~]# vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://wixr8yss.mirror.aliyuncs.com"],
"insecure-registries":["10.10.0.110:80"],
"bip":"172.31.0.1/16"
}

五、重启docker

[root@localhost ~]# systemctl restart docker

六、测试

#从官方pull busybox 镜像
[root@localhost ~]# docker pull busybox
Using default tag: latest
latest: Pulling from library/busybox
53071b97a884: Pull complete
Digest: sha256:4b6ad3a68d34da29bf7c8ccb5d355ba8b4babcad1f99798204e7abb43e54ee3d
Status: Downloaded newer image for#查看当前镜像
[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox latest 64f5d945efcc 5 days ago 1.2MB
registry latest f32a97de94e1 2 months ago 25.8MB#为镜像打tag
[root@localhost ~]# docker tag busybox:latest 10.10.0.110:80/busybox:v1#查看tag 是否标记成功
[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
10.10.0.110/busybox v1 64f5d945efcc 5 days ago 1.2MB
busybox latest 64f5d945efcc 5 days ago 1.2MB
registry latest f32a97de94e1 2 months ago 25.8MB#将镜像推送到私有镜像仓库中
[root@localhost ~]# docker push 10.10.0.110:80/busybox:v1
The push refers to repository [10.10.0.110:80/busybox]
d1156b98822d: Pushed

[root@localhost repositories]# docker pull 10.10.0.110:80/busybox:v1
v1: Pulling from busybox
53071b97a884: Pull complete
Digest: sha256:4fe8827f51a5e11bb83afa8227cbccb402df840d32c6b633b7ad079bc8144100
Status: Downloaded newer image for 10.10.0.110:80/busybox:v1

七、查看当前私有仓库中有哪些镜像以及镜像的tag

[root@localhost repositories]#//10.10.0.110:80/v2/_catalog
{"repositories":["busybox"]}
[root@localhost repositories]# curl http://10.10.0.110:80/v2/busybox/tags/list
{"name":"busybox","tags":["v1"]}
