-## Upgrading Kubernetes versions
-
-The original project was built using Kubernetes 1.13.
-Some of the API's have been deprecated and do not work with version 1.16.
-
-`kubectl` can be used to convert. E.g.:
-
-```sh
-kubectl convert -f ./kubernetes/flask-deployment.yml.yml --output-version apps/v1
-```
-
-For example, the `flask-deployment.yml` went from:
-
-```yaml
-apiVersion: extensions/v1beta1
-kind: Deployment
-...
-```
-
-to:
-
-```yaml
-apiVersion: apps/v1
-kind: Deployment
-...
-```
-
-A number of new default values are added in the conversion too.
