# Accessing the Unreal Engine Source Code and Container Registry
With your Github Account join the Epic Games Organization to access the Unreal Engine source code by following the steps at [ue-on-github](https://www.unrealengine.com/en-US/ue-on-github).
1. Get a GitHub account
2. Open your Unreal Engine account dashboard
3. Connect GitHub
4. Link the accounts
5. Authorize
6. Accept the email invitation
- [Overview of Containers in Unreal Engine](https://docs.unrealengine.com/5.0/en-US/overview-of-containers-in-unreal-engine/)
- [Unreal Containers by Adam Rehn (Creator)](https://unrealcontainers.com/docs/use-cases/)
# Copying the UE4 images to gitlab-registry.nrp-nautilus.io
The Nautilus Cluster is hooked up in such a way to allow [faster image downloading](https://ucsd-prp.gitlab.io/userdocs/running/fast-img-download/). Thus, we create and upload images of our Unreal Projects to the gitlab container registry for quicker deployments and Continuous Integration Continous Development (CI/CD) pipelines.
## Authentication
_Method 1:_
Navigate to Github Account Settings > Developer Settings > Personal Access Tokens
Generate new token
For "Note" enter "UE4-YOURINITIALFIRSTLASTNAME" (i.e UE4-GV) or whataver alias you'd like. Make sure the following scopes are checked true as well.
<img src="/uploads/01cc89bfadfa7c4f8c29cfbc7a621ea0/image.png" width="50%" height="50%">
Save the token somewhere as you won't be able to recover it and will have to generate a new one.
It should look something like `ghp_PqZZV52LLeFGiPAJOT1xr4cFtOUDjS4O9xMS`.
Now you should be able to authenticate your terminal to communicate with the Private Github Registry.
`echo "ghp_PqZZV52LLeFGiPAJOT1xr4cFtOUDjS4O9xMS" | docker login ghcr.io --username USERNAME --password-stdin`
_Method 2:_
docker login ghcr.io -u USERNAME
You should now be able to view and pull images from [https://github.com/orgs/EpicGames/packages](https://github.com/orgs/EpicGames/packages)
## Download the latest UE images locally
docker pull ghcr.io/epicgames/unreal-engine:dev-4.27
docker tag ghcr.io/epicgames/unreal-engine:dev-4.27 gitlab-registry.nrp-nautilus.io/ar-noc/arnoc-alpha/unreal-engine:dev-4.27.2
docker login gitlab-registry.nrp-nautilus.io -u USERNAME
docker push gitlab-registry.nrp-nautilus.io/ar-noc/arnoc-alpha/unreal-engine:dev-4.27.2
