Update dhall-kubernetes version to v4.0.0
This change update the kubernetes binding to use the new Optional types. The main consequence is that all the fields that are optional needs to be prefixed with Some. This let us remove the `--omit-empty` parameter resulting in cleaner resources where we don't need to set a dummy emptyDir medium value. See this issue for the details: https://github.com/dhall-lang/dhall-kubernetes/issues/86 Change-Id: I23a0a028909208cd58f57a6f07ee93090b3f3a1a

Then you can evaluate the resources function, for example to get the scheduler service:
|
||||
|
||||
```bash
|
||||
dhall-to-yaml --omit-empty --explain <<< "(./conf/zuul/resources.dhall ($INPUT)).Components.Zuul.Scheduler"
|
||||
dhall-to-yaml --explain <<< "(./conf/zuul/resources.dhall ($INPUT)).Components.Zuul.Scheduler"
|
||||
```
|
||||
|
||||
Or get all the kubernetes resources:
|
||||
|
||||
```bash
|
||||
dhall-to-yaml --omit-empty <<< "(./conf/zuul/resources.dhall ($INPUT)).List"
|
||||
dhall-to-yaml <<< "(./conf/zuul/resources.dhall ($INPUT)).List"
|
||||
```
