一、搭建本地私有仓库

1、下载registry镜像

[root@localhost ~]#docker pull registry
Using default tag: latest
latest: Pulling from library/registry
79e9f2f55bf5: Pull complete 
0d96da54f60b: Pull complete 
5b27040df4a2: Pull complete 
e2ead8259a04: Pull complete 
3790aef225b9: Pull complete 
Digest: sha256:169211e20e2f2d5d115674681eb79d21a217b296b43374b8e39f97fcf866b375
Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest
[root@localhost ~]#docker images 
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
nginx        latest    7383c266ef25   8 days ago    188MB
registry     latest    b8604a3fe854   2 years ago   26.2MB

2、在daemon.json文件中添加私有镜像仓库地址

[root@localhost ~]#cd /etc/docker/
[root@localhost docker]#ls
daemon.json

[root@localhost ~]#vim /etc/docker/daemon.json

{
  "insecure-registries": ["192.168.10.100:5000"],
  "registry-mirrors": ["https://5nbz4xnp.mirror.aliyuncs.com"]
}

[root@localhost docker]#systemctl restart docker.service
