Irbe Krumina	00517c8189	kube/{kubeapi,kubeclient},ipn/store/kubestore,cmd/{containerboot,k8s-operator}: emit kube store Events (#14112 ) Adds functionality to kube client to emit Events. Updates kube store to emit Events when tailscaled state has been loaded, updated or if any errors where encountered during those operations. This should help in cases where an error related to state loading/updating caused the Pod to crash in a loop- unlike logs of the originally failed container instance, Events associated with the Pod will still be accessible even after N restarts.

Irbe Krumina	9d1348fe21	ipn/store/kubestore: don't error if state cannot be preloaded (#13926 ) Preloading of state from kube Secret should not error if the Secret does not exist. Updates tailscale/tailscale#7671 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	4 weeks ago
Irbe Krumina	853fe3b713	ipn/store/kubestore: cache state in memory (#13918 ) Cache state in memory on writes, read from memory in reads. kubestore was previously always reading state from a Secret. This change should fix bugs caused by temporary loss of access to kube API server and imporove overall performance Fixes #7671 Updates tailscale/tailscale#12079,tailscale/tailscale#13900 Signed-off-by: Maisem Ali <maisem@tailscale.com> Signed-off-by: Irbe Krumina <irbe@tailscale.com> Co-authored-by: Maisem Ali <maisem@tailscale.com>	4 weeks ago
Irbe Krumina	209567e7a0	kube,cmd/{k8s-operator,containerboot},envknob,ipn/store/kubestore,*/depaware.txt: rename packages (#13418 ) Rename kube/{types,client,api} -> kube/{kubetypes,kubeclient,kubeapi} so that we don't need to rename the package on each import to convey that it's kubernetes specific.

Irbe Krumina	d6dfb7f242	kube,cmd/{k8s-operator,containerboot},envknob,ipn/store/kubestore,*/depaware.txt: split out kube types (#13417 ) Further split kube package into kube/{client,api,types}. This is so that consumers who only need constants/static types don't have to import the client and api bits. Updates#cleanup Signed-off-by: Irbe Krumina <irbe@tailscale.com>	3 months ago

Maisem Ali	c919ff540f	cmd/k8s-operator,ipn/store/kubestore: patch secrets instead of updating We would call Update on the secret, but that was racey and would occasionaly fail. Instead use patch whenever we can. Fixes errors like ``` boot: 2023/08/29 01:03:53 failed to set serve config: sending serve config: updating config: writing ServeConfig to StateStore: Operation cannot be fulfilled on secrets "ts-webdav-kfrzv-0": the object has been modified; please apply your changes to the latest version and try again {"level":"error","ts":"2023-08-29T01:03:48Z","msg":"Reconciler error","controller":"ingress","controllerGroup":"networking.k8s.io","controllerKind":"Ingress","Ingress":{"name":"webdav","namespace":"default"},"namespace":"default","name":"webdav","reconcileID":"96f5cfed-7782-4834-9b75-b0950fd563ed","error":"failed to provision: failed to create or get API key secret: Operation cannot be fulfilled on secrets \"ts-webdav-kfrzv-0\": the object has been modified; please apply your changes to the latest version and try again","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(Controller).reconcileHandler\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:324\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(Controller).processNextWorkItem\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:265\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\tsigs.k8s.io/controller-runtime@v0.15.0/pkg/internal/controller/controller.go:226"} ``` Updates #502 Updates #7895 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	e0d291ab8a	ipn/store: add support for stores to hook into a custom dialer For stores like k8s secrets we need to dial out to the k8s API as though Tailscale wasn't running. The issue currently only manifests when you try to use an exit node while running inside a k8s cluster and are trying to use Kubernetes secrets as the backing store. This doesn't address cmd/containerboot, which I'll do in a follow up. Updates #7695 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	9d8b7a7383	ipn/store/kubestore: handle "/" in ipn.StateKeys Kubernetes doesn't allow slashes as keys in secrets, replace them with "__". This shows up in the kubernetes-operator now that tsnet sets resets the ServeConfig at startup. Fixes #7662 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Maisem Ali	497324ddf6	ipn/store: add common package for instantiating ipn.StateStores Also move KubeStore and MemStore into their own package. RELNOTE: tsnet now supports providing a custom ipn.StateStore. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago
