Editor to share with you docker how to build a private warehouse, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

In Docker, when we execute docker pull xxx, it is actually looking from the address of registry.hub.docker.com, which is the public warehouse provided by Docker. In our work, it is impossible for us to manage the enterprise project push to the public warehouse. So in order to better manage images, Docker not only provides a central repository, but also allows us to build local private repositories.

1. Registry and harbor

Registry is just a pure character set repository. Harbor has its own interface.

The location of harbor is registry,registry, which is just a component of harbor.

Harbor consists of eight containers, one of which is registry

Location where docker images is saved

[root@localhost ~] # cd / var/lib/docker/image/ [root@localhost image] # lsoverlay2 build a private warehouse [root@localhost ~] # docker pull registry download directly

[root@localhost ~] # vim / etc/docker/daemon.json "insecure-registries": ["192.168.133.101 insecure-registries"], add this sentence in the second line

[root@localhost ~] # systemctl restart docker [root@localhost ~] # docker run-d-p 5000 docker run-v / data/registry:/tmp/registry registry824be90701645f27f8b90b50d0cb5f985c189ef9b452c8c8741ae1c6beed4fbc-d daemon-p designated port-v set mount directory last registry startup warehouse

View the image in the repository. It is currently empty.

[root@localhost ~] # curl-XGET http://192.168.133.101:5000/v2/_catalog{"repositories":[]} # v2 is the version _ catalog is to view data

Push the local image to the warehouse

It cannot be pushed directly. It must be marked first.

[root@localhost ~] # docker tag nginx:v4 192.168.133.101:5000/nginx is root by default

Upload image

[root@localhost ~] # docker push 192.168.133.101:5000/nginx

Download from private warehouse

Remove the original mirror image first

Root@localhost ~] # docker rmi 192.168.133.101:5000/nginx

Download images from private repositories

[root@localhost ~] # docker pull 192.168.133.101:5000/nginx
