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.

apiVersion: v1
kind: Namespace
metadata:
  name: element-web

---

# 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.
