DNS for service discovery is fraught with perils. Many implementations don't respect TTLs, or don't actually use multiple records, or don't do something smart like power of two. Even if you pick all your impls carefully, you have to wait for your TTL instead of a push mechanism for changes. If you wanted to implement the watch as a library, code wise, it's maybe ~500 lines per language, using the k8s client lib. I could hammer it out in two days. |
