docker搭建本地registry

第一步：拉取registry镜像

[root@localhost iso]# docker image 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: sha256:8004747f1e8cd820a148fb7499d71a76d45ff66bac6a29129bfdbfdc0154d146
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest

第二步：查看镜像构建历史信息

[root@localhost iso]# docker image history registry
IMAGE CREATED CREATED BY SIZE COMMENT
f32a97de94e1 8 months ago /bin/sh -c #(nop) CMD ["/etc/docker/registr… 0B 
<missing> 8 months ago /bin/sh -c #(nop) ENTRYPOINT ["/entrypoint.… 0B 
<missing> 8 months ago /bin/sh -c #(nop) COPY file:507caa54f88c1f38… 155B 
<missing> 8 months ago /bin/sh -c #(nop) EXPOSE 5000 0B 
<missing> 8 months ago /bin/sh -c #(nop) VOLUME [/var/lib/registry] 0B 
<missing> 8 months ago /bin/sh -c #(nop) COPY file:4544cc1555469403… 295B 
<missing> 8 months ago /bin/sh -c #(nop) COPY file:21256ff7df5369f7… 20.1MB 
<missing> 8 months ago /bin/sh -c set -ex && apk add --no-cache… 1.29MB 
<missing> 8 months ago /bin/sh -c #(nop) CMD ["/bin/sh"] 0B 
<missing> 8 months ago /bin/sh -c #(nop) ADD file:38bc6b51693b13d84… 4.41MB

第三步：启动容器

[root@localhost ~]# docker run --name refistry -d -p 8878:5000 -v /registry:/var/lib/registry registry 
c2da1e4739006621455c09f1c319e67a063350b050d8cc4c07257b898a7536ce
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c2da1e473900 registry "/entrypoint.sh /etc…" 50 seconds ago Up 50 seconds 0.0.0.0:8878->5000/tcp refistry

第四步：镜像改名

[root@localhost ~]# docker tag httpd 192.168.59.200:8878/http:test
[root@localhost ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest f32a97de94e1 8 months ago 25.8MB
192.168.59.200:8878/http test fb2f3851a971 18 months ago 178MB
httpd latest fb2f3851a971 18 months ago 178MB

第五步：修改docker文件并重启

[root@localhost docker]# vim daemon.json 
{
"registry-mirrors": ["https://XXX.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.59.200:8878"]
}
[root@localhost docker]# systemctl restart docker

'''
原因：

[root@localhost ~]# docker image push 192.168.59.200:8878/http
The push refers to repository [192.168.59.200:8878/http]
Get https://192.168.59.200:8878/v2/: http: server gave HTTP response to HTTPS client

'''

第六步：重启registry容器

[root@localhost docker]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c2da1e473900 registry "/entrypoint.sh /etc…" 12 minutes ago Exited (2) About a minute ago refistry
0400349ee7c8 httpd "httpd-foreground" 53 minutes ago Exited (0) About a minute ago httpd-test2
e60cdf12daa7 httpd "httpd-foreground" About an hour ago Exited (0) About a minute ago http-test
391afba79c84 httpd "httpd-foreground" About an hour ago Exited (0) About a minute ago httpd
9225fd6da0e2 tomcat:test "catalina.sh run" 2 hours ago Exited (143) About a minute ago tomcat
[root@localhost docker]# docker restart c2da1e473900

第七步：推送

[root@localhost docker]# docker image push 192.168.59.200:8878/http
The push refers to repository [192.168.59.200:8878/http]
0f8d971d177b: Pushed 
97fd31ecd005: Pushed 
82155933cfa6: Pushed 
2fd9f57029b0: Pushed 
02bd518ef304: Pushed 
b8342f9976fc: Pushed

[root@localhost docker]#

第八步：查找本地库

[root@localhost docker]# docker container inspect c2da1e473900|grep -i "source"
"Source": "/registry",
[root@localhost repositories]# cd
[root@localhost ~]# cd /registry/docker/registry/v2/repositories
[root@localhost repositories]# ls
http
[root@localhost repositories]# 

附加：

删除镜像

[root@localhost ~]# docker image rm 192.168.59.200:8878/http

拉取镜像：

[root@localhost ~]# docker pull 192.168.59.200:8878/http
