@ -3,14 +3,24 @@ title: Setting up private docker registry for Compute-to-Data 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
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.
3. SSL certificate
## Generate certificates
```bash
# install certbot: https://certbot.eff.org/
sudo certbot certonly --standalone --cert-name example.com -d example.com

## Other useful commands
### Login to registry

Use the commands below to build an image from a `Dockerfile` and push it to your private registry.
```bash
docker build . -t example.com/my-algo:latest
docker build . -t admin.example.com/my-algo:latest
docker image push admin.example.com/my-algo:latest
```
docker image tag example.com/my-algo:latest
## List images in the registry
```bash
curl -X GET -u <username>:<password> https://example.com/v2/_catalog
```
## Pull an image from the registry
Use the commands below to build an image from a `Dockerfile` and push it to your private registry.
```bash
docker image pull example.com/my-algo:latest
```
## Next step
You can publish an algorithm asset with the metadata containing registry URL, image, and tag information to enable users to run C2D jobs.
