Docker将本地的镜像上传到私有仓库

使用register镜像创建私有仓库

[root@openEuler-node1 ~]# docker run --restart=always -d -p 5000:5000 -v /opt/data/regostry:/var/lib/registry registry:2

[root@openEuler-node1 ~]# docker images
REPOSITORY                                          TAG         IMAGE ID       CREATED        SIZE
registry                                            2           a8781fe3b7a2   5 weeks ago    25.4MB
busybox                                             latest      3f57d9401f8d   6 weeks ago    4.26MB
ubuntu                                              18.04       f9a80a55f492   9 months ago   63.2MB
centos                                              7           eeb6ee3f44bd   2 years ago    204MB

（1） 先将本地仓库打上合适的标签

[root@openEuler-node1 ~]# docker tag busybox:latest 192.168.136.55:5000/busybox:v1

 （2）尝试上传镜像

[root@openEuler-node1 ~]# docker pull 192.168.136.55:5000/busybox:v1
Error response from daemon: Get "https://192.168.136.55:5000/v2/": http: server gave HTTP response to HTTPS client

上传镜像失败，原因：docker上传下载默认只支持https协议，搭建的私有仓库是https协议。

（3） 修改重启docker服务

[root@openEuler-node1 ~]# mkdir /etc/docker
[root@openEuler-node1 ~]# vim /etc/docker/daemon.json
 
{
        "insecure-registries":["192.168.136.55:5000"]
}       
[root@openEuler-node1 ~]# systemctl daemon-reload 
[root@openEuler-node1 ~]# systemctl restart docker.service 

（4）再次上传镜像，成功

[root@openEuler-node1 ~]# docker push 192.168.136.55:5000/busybox:v1
The push refers to repository [192.168.136.55:5000/busybox]
2e112031b4b9: Pushed 
v1: digest: sha256:d319b0e3e1745e504544e931cde012fc5470eba649acc8a7b3607402942e5db7 size: 527

（5）验证

[root@openEuler-node1 ~]# ll /opt/data/regostry/docker/registry/v2/repositories/
总用量 4
drwxr-xr-x 5 root root 4096  3月  3 11:58 busybox

我们可以用可视化界面registry-web(docker自带的)来管理

[root@openEuler-node1 ~]# docker run -d -p 8080:8080 --name registry-web --restart=always --link b2878bdb5e1b -e registry_url=http://192.168.136.55:5000/v2 -e registry_name=localhost:5000 hyper/docker-registry-web:latest
