How to build a local warehouse with docker

#How docker build a local warehouse?

1. After installing docker

yum install docker -y

, specify the docker installation directory as required, or create a new disk and use docker-storage-setup to use

2. Set up a third-party docker image for acceleration

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

3. Install the docker local warehouse

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

4. Start the local warehouse

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

5. Upload the image to the warehouse

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

6. Log in to the registry to view the uploaded content

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

7. View the images directory of the warehouse

[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. Other servers obtain images from the registry and append the following information

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

9. Get 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
