Docker–registry

The difference between registry and harbor

• registry: character interface
• barbro: own web interface

Build a private warehouse

• Download mirror

[root@docker ~]# docker pull registry

• Set in the docker engine terminal

[root@docker ~]# vim /etc/docker/daemon.json
{
    
    
  "insecure-registries":["192.168.15.11:5000"],     #指向本地仓库位置
  "registry-mirrors": ["镜像加速"]
}

[root@docker ~]# systemctl restart docker


##查看镜像并运行
[root@docker ~]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE
registry     latest    5c4008a25e05   3 weeks ago   26.2MB
nginx                      latest    f6d0b4767a6c   2 months ago   133MB
[root@docker ~]# docker create -it registry bash
57bc015dbf1b9b5994d53f0b7796a19516c219fff21af1e7246acd92cb25772c
[root@docker ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND                 CREATED         STATUS    PORTS     NAMES

##如果此时运行镜像会产生运行异常，因为没有任何守护进程支持运行
[root@docker ~]# docker start 57bc015dbf1b
57bc015dbf1b
docker ps -a
CONTAINER ID   IMAGE      COMMAND                 CREATED         STATUS                       PORTS     NAMES

##运行registey的正确方式：宿主机的/data/registry自动创建挂载容器中的/tmp/registry
[root@docker ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry
# /data/registry：宿主机目录
# /tmp/registry：容器目录
# registry：运行的镜像

[root@docker ~]# docker ps -a 
CONTAINER ID   IMAGE      COMMAND                  CREATED         STATUS                      PORTS                    NAMES

##查看私有仓库内有无镜像
[root@docker ~]# curl -XGET http://192.168.15.11:5000/v2/_catalog
{
    
    "repositories":[]}

##更改标记为192.168.15.11:5000/nginx
[root@docker ~]# docker tag nginx:latest 192.168.15.11:5000/nginx
[root@docker ~]# docker images
REPOSITORY                 TAG       IMAGE ID       CREATED        SIZE
