docker怎么在本地建倉庫？

1.安裝docker

yum install docker -y

之后根據需求把指定docker安裝目錄，或者新建一個磁盤使用docker-storage-setup來使用

2.設置第三方docker鏡像來做加速

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

3.安裝docker本地倉庫

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

4.啟動本地倉庫

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

5.上傳鏡像到倉庫中

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

6.登陸到registry查看上傳的內容

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

7.查看倉庫的images目錄

[root@localhost ~]# curl http://registry:5000/v2/_catalog  #目錄{"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.其他服務器從registry來獲取鏡像，追加以下信息

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

9.獲取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
