# Install with K8S
## Community Maintained Helm Chart
We recommend you use the [community maintained helm chart](./install-with-helm.md) to
install Baserow on K8S.
## Raw K8S starting point
See below for a starting point for a K8S configuration file which deploys a production
ready Baserow.
It assumes you want the most performant version of Baserow possible and
so deploys separate wsgi and asgi backend services, separate async task workers etc.
You will need to also provide a redis and postgres instance configured using the
environment variables below. See [Configuring Baserow](./configuration.md) for more
details on these variables.
You should also set up and configure Baserow to use an S3 compatible storage service
for uploading and serving user uploaded files.
## Example baserow.yml
```yaml
