Running in Kubernetes
=====================
In case you would like to deploy element-web in a kubernetes cluster you can use
the provided Kubernetes example below as a starting point. Note that this example assumes the
Nginx ingress to be installed.
Note that the content of the required `config.json` is defined inside this yaml because it needs
to be put in your Kubernetes cluster as a `ConfigMap`.
So to use it you must create a file with this content as a starting point and modify it so it meets
the requirements of your environment.
Then you can deploy it to your cluster with something like `kubectl apply -f my-element-web.yaml`.
