How to build a local private warehouse with Docker (detailed example)

This article brings you relevant knowledge about building a local private warehouse in docker, including using registry images to create private warehouses and checking whether the build is successful and other related issues. I hope it will be helpful to everyone.

Use the registry image to create a private warehouse

docker run -itd --restart always --name docker-hub -p 5000:5000 -v /opt/data/registry:/var/lib/registry registry

View the private warehouse that does not store the image yet, so it is displayed as empty

curl -XGET 127.0.0.1:5000/v2/image_name/tags/list

Create a new image (named with ip: port), and try push

ifconfig | grep inet

I know that the local IP is 172.17.0.1

1. Create a new container

docker tag ubuntu:18.04 172.17.0.1:5000/test

2. push image

docker push 172.17.0.1:5000/test

If

Get https://172.17.0.1:5000/v2/: http : server gave HTTP response to HTTPS client

Don’t panic, just change the machine configuration (/etc/docker/daemon.json). First of all, avoid being handicapped. First use cp to back up

cp daemon.json daemon.json.bak

and then change the content of daemon.json

{"insecure-registries":["172.17.0.1:5000"]}

The value of insecure-registries is an iterable list, you can add ip:port by yourself

Remember to change to your own IP and port

Restart Docker

systemctl restart docker

Finally push successfully

docker push 172.17.0.1:5000/test

##Check whether the build is successful /Try to pull the file you just pushed

Delete the original image

docker rmi 172.17.0.1:5000/test  #将原来push的镜像删掉,方便等会pull检验echo 'DOCKER_OPTS="--insecure-registry 172.17.0.1:5000/test' >> /etc/default/docker

If it is just an experiment, writing 0.0.0.0/0 (all ip ports) is not impossible

service docker restart		#重启服务docker pull 172.17.0.1:5000/test	#pull下之前push的镜像

After downloading, you can change the name of the image under pull to facilitate future calls.
