description: Learn how to setup your own docker registry and push images for running algorithms in a C2D environment. description: Learn how to setup your own docker registry and push images for running algorithms in a C2D environment.

The tutorial provides the steps to setup a private docker registry on the server. The document is intended for a production setup where anyone can pull the image from the registry but, only authenticated users will push images to the registry.
To implement this use case, 2 domains will be required:
- example.com: This domain will allow only image pull operations
- admin.example.com: This domain will allow image push/pull operations only to the authenticated users.
_Note: Please change the domain names to your application-specific domain names._
## Prerequisites ## Prerequisites
1. Running docker environment on the server. 1. Running docker environment on the server.
2. Domain name is mapped to the server IP address. 2. 2 domain names is mapped to the same server IP address.

## Generate certificates ## Generate certificates
```bash ```bash
# install certbot: https://certbot.eff.org/ # install certbot: https://certbot.eff.org/
sudo certbot certonly --standalone --cert-name example.com -d example.com sudo certbot certonly --standalone --cert-name example.com -d example.com
