Irbe Krumina	c3e2b7347b	tailcfg,cmd/k8s-operator,kube: move Kubernetes cap to a location that can be shared with control (#12236 ) This PR is in prep of adding logic to control to be able to parse tailscale.com/cap/kubernetes grants in control: - moves the type definition of PeerCapabilityKubernetes cap to a location shared with control. - update the Kubernetes cap rule definition with fields for granting kubectl exec session recording capabilities. - adds a convenience function to produce tailcfg.RawMessage from an arbitrary cap rule and a test for it. An example grant defined via ACLs: "grants": [{ "src": ["tag:eng"], "dst": ["tag:k8s-operator"], "app": { "tailscale.com/cap/kubernetes": [{ "recorder": ["tag:my-recorder"] “enforceRecorder”: true }], }, } ] This grant enforces `kubectl exec` sessions from tailnet clients, matching `tag:eng` via API server proxy matching `tag:k8s-operator` to be recorded and recording to be sent to a tsrecorder instance, matching `tag:my-recorder`. The type needs to be shared with control because we want control to parse this cap and resolve tags to peer IPs.

Irbe Krumina	82576190a7	tailcfg,cmd/k8s-operator: moves tailscale.com/cap/kubernetes peer cap to tailcfg (#12235 ) This is done in preparation for adding kubectl session recording rules to this capability grant that will need to be unmarshalled by control, so will also need to be in a shared location.

Joe Tsai	c25968e1c5	all: make use of ctxkey everywhere (#10846 ) Also perform minor cleanups on the ctxkey package itself. Provide guidance on when to use ctxkey.Key[T] over ctxkey.New. Also, allow for interface kinds because the value wrapping trick also happens to fix edge cases with interfaces in Go.

Irbe Krumina	af49bcaa52	cmd/k8s-operator: set different app type for operator with proxy (#10081 ) Updates tailscale/tailscale#9222 plain k8s-operator should have hostinfo.App set to 'k8s-operator', operator with proxy should have it set to 'k8s-operator-proxy'. In proxy mode, we were setting the type after it had already been set to 'k8s-operator' Signed-off-by: Irbe Krumina <irbe@tailscale.com>	1 year ago

Maisem Ali	335a5aaf9a	cmd/k8s-operator: add APISERVER_PROXY env The kube-apiserver proxy in the operator would only run in auth proxy mode but thats not always desirable. There are situations where the proxy should just be a transparent proxy and not inject auth headers, so do that using a new env var APISERVER_PROXY and deprecate the AUTH_PROXY env. THe new env var has three options `false`, `true` and `noauth`. Updates #8317 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago

Maisem Ali	7f6bc52b78	cmd/k8s-operator: refactor operator code It was jumbled doing a lot of things, this breaks it up into the svc reconciliation and the tailscale sts reconciliation. Prep for future commit. Updates #502 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	24509f8b22	cmd/k8s-operator: add support for control plane assigned groups Previously we would use the Impersonate-Group header to pass through tags to the k8s api server. However, we would do nothing for non-tagged nodes. Now that we have a way to specify these via peerCaps respect those and send down groups for non-tagged nodes as well. For tagged nodes, it defaults to sending down the tags as groups to retain legacy behavior if there are no caps set. Otherwise, the tags are omitted.
