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`.
# This is an example of a POSSIBLE config for deploying a single element-web instance in Kubernetes
# Use the element-web namespace to put it all in.

# The config.json file is to be put into Kubernetes as a config file in such a way that
# the element web instance can read it.
# The code below shows how this can be done with the config.sample.json content.
