logging of application logs generally in the world is an unsolved problem, but I feel like k8s does better than most; fluentd is the default, and then logs are collected by whatever end system you like the best that's appropriate for your needs (e.g. GKE -> fluentd -> Cloud Logging, and I've heard of K8S -> fluentd -> ELK).
since most people use k8s in the context of GKE.. there seems to be some magic that Google has put in.
But if you read the bug, this doesnt work quite well in the wild. In fact, an entire spec is being written on it and right now the debate is whether to forward to journald and have it proxy further or reimplement a new logging format.
well, there's definitely systemd people pushing for journald, that's for sure. The first comment talks about how it doesn't fit, though. I wonder what in particular about the solution doesn't work for those people.
