2. Metrics Server
3. Kyverno

[Optional] Nuon DNS

Nuon offers the option to provision complementary nuon.run domains for ease of use. To enable the nuon dns, set enable_nuon_dns to true or 1.

Note: The domain names are provided by Nuon automatically and cannot be customized.

Resources

When Nuon DNS is enabled, the following Helm Charts are installed.

Chart	Version
alb-ingress-controller	1.12.0
cert-manager	1.11.0
external-dns	1.12.0
ingress-nginx	4.12.1

And the following AWS Resources will be created.

• Route 53 Zone

Additionally, some default internal and public cert issuers (cert-manager) are created.
