Hi All

We are working on a POC to explore Cosmos on Pega 8.6 sand box and we have a base installation of Pega 8.6 on RHEL 8 and we want to explore Cosmos. As cosmos needs Constellation and there are no specific detail on install guide for the same and when I browse on PDN it gives only detail or an image for docker or helm based constellation service install. Can someone detail if there is any additional install steps for on premise Pega 8.6 on RHEL to explore Cosmos without docker.

@KrishnaK7281 to explore Cosmos, you don’t need Constellation Engine. Cosmos is shipped with pega, you just need to build your app on top of Theme-Cosmos application.

Constellation is only needed if you want to explore React based features. But that’s more advanced topic.

@RandhirS4721 I have not been able to find any documentation. It seems restricted to the use of docker/kubernetes

[Cosmos React](https://docs-previous.pega.com/user-experience-cosmos-react/87/cosmos-react)

[Constellation UI static content service](https://documents.constellation.pega.io/static/86-87/introduction.html)

[Containerized deployments in Kubernetes environments](https://docs.pega.com/bundle/platform-88/page/platform/deployment/client-managed-cloud/containerized-deployments-kubernetes.html)

[Pega-provided Docker images](https://docs.pega.com/bundle/platform-88/page/platform/deployment/client-managed-cloud/pega-docker-images-manage.html)

Here is a cut-down version of[Deploying Pega 8.X In Kubernetes](https://support.pega.com/discussion/deploying-pega-8x-kubernetes) for training purposes only.
