docker怎么在本地建仓库

docker怎么在本地建仓库？

1.安装docker

yum install docker -y

之后根据需求把指定docker安装目录，或者新建一个磁盘使用docker-storage-setup来使用

2.设置第三方docker镜像来做加速

vim /etc/docker/daemon.json {"registry-mirrors": ["http://hub-mirror.c.163.com",{"insecure-registries":["registry:5000"]}] }

3.安装docker本地仓库

systemctl start docker docker pull docker.io/registry docker images

4.启动本地仓库

docker run -d --name=registry -p 5000:5000 docker.io/registry

5.上传镜像到仓库中

docker tag docker.io/registry registry:5000/resistry:v1 docker push registry:5000/resistry:v1

6.登陆到registry查看上传的内容

docker exec -it registry sh / # ls /var/lib/registry/docker/registry/v2/repositories/resistry

7.查看仓库的images目录

[root@localhost ~]# curl http://registry:5000/v2/_catalog  #目录{"repositories":["centos","resistry"]} [root@localhost ~]# curl http://registry:5000/v2/centos/tags/list  #image的版本信息{"name":"centos","tags":["6.9","6"]} [root@localhost ~]# curl http://registry:5000/v2/image_name/tags/list{"errors":[{"code":"NAME_UNKNOWN","message":"repository name not known to registry","detail":{"name":"image_name"}}]} [root@localhost ~]#

8.其他服务器从registry来获取镜像，追加以下信息

vim /etc/docker/daemon.json { {"insecure-registries":["registry:5000"]} }

9.获取images

docker pull registry:5000/centos:6.9docker images REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE registry:5000/centos   6.9                 2199b8eb8390        11 months ago       195 MB
