前言：
今天咱们对“ubuntu devsda”大体比较珍视，同学们都需要了解一些“ubuntu devsda”的相关内容。那么小编同时在网上汇集了一些关于“ubuntu devsda””的相关知识，希望兄弟们能喜欢，朋友们一起来学习一下吧！1 安装docker环境
为了能快速拉取镜像，建议配置一下docker的国内镜像加速地址，网上这类教程很多，docker安装此处不再赘述，也可参考《Debian及ubuntu下如何搭建docker运行环境》
2 拉取registry镜像
root@debian:~# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
79e9f2f55bf5: Pull complete
0d96da54f60b: Pull complete
5b27040df4a2: Pull complete

Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest
root@debian:~# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
registry latest b8604a3fe854 12 months ago 26.2MB
3 在宿主机上创建数据存储目录
root@debian:/# mkdir -p /opt/registryData
4 启动registry容器
容器配置为后台运行，将容器服务端口映射到宿主机80端口，挂载数据存储目录，设置容器自启动
root@debian:/# docker run -d -p 80:5000 -v /opt/registryData:/var/lib/registry --restart=always --name localRegistry registry
3e039e259a2d03925b4a6937e1c498c568a707e99c04ce9bc29cf716ad3a40c2
root@debian:/# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3e039e259a2d registry "/entrypoint.sh /etc…" About a minute ago Up About a minute 0.0.0.0:80->5000/tcp, :::80->5000/tcp localRegistry
5 配置私有仓库地址
root@debian:/# vi /etc/docker/daemon.json
{
"registry-mirrors": [";],
"insecure-registries": ["192.168.100.200"] ##新增
}
6 重启docker服务
root@debian:/# systemctl restart docker
root@debian:/# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
root@debian:/# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3e039e259a2d registry "/entrypoint.sh /etc…" 10 minutes ago Up 3 seconds 0.0.0.0:80->5000/tcp, :::80->5000/tcp localRegistry
7 测试私有镜像库是否工作正常
拉取nginx镜像
root@debian:/# docker pull nginx:latest
latest: Pulling from library/nginx
a2abf6c4d29d: Pull complete
a9edb18cadd1: Pull complete
589b7251471a: Pull complete
186b1aaa4aa6: Pull complete
b4df32aa5a72: Pull complete

Status: Downloaded newer image for nginx:latest
docker.io/library/nginx:latest
标记本地nginx镜像，归入本地私有仓库
root@debian:/# docker tag nginx:latest 192.168.100.200/nginx
将镜像推送到本地私有仓库
root@debian:/# docker push 192.168.100.200/nginx
Using default tag: latest
The push refers to repository [192.168.100.200/nginx]

删除本地相关的nginx镜像
root@debian:/# docker rmi 192.168.100.200/nginx nginx
