David Anderson	8171eb600c	cmd/k8s-operator: move the operator into its own namespace. ... The operator creates a fair bit of internal cluster state to manage proxying, dumping it all in the default namespace is handy for development but rude for production.

David Anderson	3a5fc233aa	cmd/k8s-operator: use oauth credentials for API access. ... This automates both the operator's initial login, and provisioning/deprovisioning of proxies. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	a7ab3429b6	cmd/k8s-operator: refactor reconcile loop, un-plumbing reconcile.Result. ... We used to need to do timed requeues in a few places in the reconcile logic, and the easiest way to do that was to plumb reconcile.Result return values around. But now we're purely event-driven, so the only thing we care about is whether or not an error occurred. Incidentally also fix a very minor bug where headless services would get completely ignored, rather than reconciled into the correct state. This shouldn't matter in practice because you can't transition from a headful to a headless service without a deletion, but for consistency let's avoid having a path that takes no definite action if a service of interest does exist.

David Anderson	835a73cc1f	cmd/k8s-operator: remove unnecessary timed requeue. ... Previously, we had to do blind timed requeues while waiting for the tailscale hostname, because we looked up the hostname through the API. But now the proxy container image writes back its hostname to the k8s secret, so we get an event-triggered reconcile automatically when the time is right.

David Anderson	d857fd00b3	cmd/k8s-operator: sprinkle debug logging throughout. ... As is convention in the k8s world, use zap for structured logging. For development, OPERATOR_LOGGING=dev switches to a more human-readable output than JSON. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	8ccd707218	cmd/k8s-operator: remove times requeues in proxy deletion path. ... Our reconcile loop gets triggered again when the StatefulSet object finally disappears (in addition to when its deletion starts, as indicated by DeletionTimestamp != 0). So, we don't need to queue additional reconciliations to proceed with the remainder of the cleanup, that happens organically. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
