Private Docker registry

How to run your own private Docker registry


With Docker on the rise the need for running your own Docker containers rises as wel. With Hipex docker support this is now a piece of cake.

In this example we will be running Docker Registry.

Installation

We will be using the Hipex CLI docker commands to run the container. For the rest of this tutorial we assume you are familiar with the docker basics.

Step 1

Create your Docker configuration file in ~/domains/docker-registry.example.com/registry/docker-compose.yml.

version: '3.2'

services:
    registry:
        image: registry:2.7
        volumes:
        - registry-data:/registry_data
        ports:
        - 15000:5000

volumes:
    registry-data:

Now the service can be started using docker:compose:up.

cd ~/domains/example.com/registry/
hipex docker:compose:up --detach

Step 2

Now we setup authentication and configure Nginx to proxy requests to our new registry. More detail about basic auth can be found here.

~/domains/docker-registry.example.com/var/etc/port-443/proxy.nginx.conf

location  ~* ^\/.* {
    proxy_pass  http://127.0.0.1:15000;

    # Default proxy settings
    proxy_connect_timeout 6000;
    proxy_send_timeout    6000;
    proxy_read_timeout    6000;
    send_timeout          6000;

    proxy_set_header  Host              $http_host;
    proxy_set_header  X-Real-IP         $remote_addr;
    proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
    proxy_set_header  X-Forwarded-Proto $scheme;
}

Step 3

The registry is now usable at your domain with the default docker commands.

docker login <username>
docker push docker-registry.example.com/some-image:latest
