Cilium Ingress: UDP Service Stuck in Pending Due To Cilium Bug

[paimonsoror]

While this isn't necessarily a bug with this chart, it is something for folks to be aware of. I referenced the same in the following:

#326

Essentially, having TCP and UDP as separate services, causes an issue with service IP assignment. This is being tracked by Cilium here but may be some time before it gets resolved:

cilium/cilium#9207

Not sure if this is something that can be combined into a single service, or if there are other reasons why TCP and UDP has been moved to distinct services.

Moving to Cilium 1.17 allows this to work fwiw:

% cilium version
cilium-cli: v0.16.21 compiled with go1.23.4 on darwin/arm64
cilium image (default): v1.16.4
