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
Brad Fitzpatrick	e8551d6b40	all: use Go 1.21 slices, maps instead of x/exp/{slices,maps} Updates #8419 Signed-off-by: Brad Fitzpatrick <bradfitz@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.

Gabriel Martinez	03e848e3b5	cmd/k8s-operator: add support for priorityClassName Updates #8155 Signed-off-by: Gabriel Martinez <gabrielmartinez@sisti.pt>	2 years ago
Brad Fitzpatrick	4664318be2	client/tailscale: revert CreateKey API change, add Client.CreateKeyWithExpiry The client/tailscale is a stable-ish API we try not to break. Revert the Client.CreateKey method as it was and add a new CreateKeyWithExpiry method to do the new thing. And document the expiry field and enforce that the time.Duration can't be between in range greater than 0 and less than a second. Updates #7143 Updates #8124 (reverts it, effectively) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Matt Brown	9b6e48658f	client: allow the expiry time to be specified for new keys Adds a parameter for create key that allows a number of seconds (less than 90) to be specified for new keys. Fixes https://github.com/tailscale/tailscale/issues/7965 Signed-off-by: Matthew Brown <matthew@bargrove.com>	2 years ago
Maisem Ali	85215ed58a	cmd/k8s-operator: handle NotFound secrets getSingleObject can return `nil, nil`, getDeviceInfo was not handling that case which resulted in panics. Fixes #7303 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Craig Rodrigues	827abbeeaa	cmd/k8s-operator: print version in startup logs Fixes: #7813 Signed-off-by: Craig Rodrigues <rodrigc@crodrigues.org>	2 years ago
Andrew Dunham	f85dc6f97c	ci: add more lints (#7909 ) This is a follow-up to #7905 that adds two more linters and fixes the corresponding findings. As per the previous PR, this only flags things that are "obviously" wrong, and fixes the issues found.

Maisem Ali	558735bc63	cmd/k8s-operator: require HTTPS to be enabled for AuthProxy Updates #5055 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	489e27f085	cmd/k8s-operator: make auth proxy pass tags as Impersonate-Group We were not handling tags at all, pass them through as Impersonate-Group headers. And use the FQDN for tagged nodes as Impersonate-User. Updates #5055 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Sonia Appasamy	7985f5243a	cmd/k8s-operator: update device authorization copy "Device Authorization" was recently renamed to "Device Approval" on the control side. This change updates the k8s operator to match. Signed-off-by: Sonia Appasamy <sonia@tailscale.com>	2 years ago
Maisem Ali	49c206fe1e	tailcfg,hostinfo: add App field to identify tsnet uses This allows us to differentiate between the various tsnet apps that we have like `golinks` and `k8s-operator`. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	06a10125fc	cmd/k8s-operator: set hostinfo.Package This allows identifying the operator. Updates #5055 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Maisem Ali	05adf22383	cmd/k8s-operator: add support for running an auth proxy Updates #5055 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
David Anderson	e51cf1b09d	cmd/k8s-operator: use unstable tailscale image as well We need a post-1.36 tailscale image to handle custom hostnames correctly. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	0dc9cbc9ab	cmd/k8s-operator: use the unstable operator image There is no stable release yet, and for alpha we want people on the unstable build while we iterate. Updates #502 Signed-off-by: David Anderson <danderson@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
David Anderson	9bd6a2fb8d	cmd/k8s-operator: support setting a custom hostname. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Vince Prignano	30380403d0	cmd/k8s-operator: remove use of InjectClient (deprecated) The dependency injection functionality has been deprecated a while back and it'll be removed in the 0.15 release of Controller Runtime. This changeset sets the Client after creating the Manager, instead of using InjectClient. Signed-off-by: Vince Prignano <vince@prigna.com>	2 years ago
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. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
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. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
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. Updates #502 Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
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
David Anderson	9c77205ba1	cmd/k8s-operator: add more tests for "normal" paths. Tests cover configuring a proxy through an annotation rather than a LoadBalancerClass, and converting between those two modes at runtime. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	c902190e67	cmd/k8s-operator: factor out some of the larger expected test outputs. For other test cases, the operator is going to produce similar generated objects in several codepaths, and those objects are large. Move them out to helpers so that the main test code stays a bit more intelligible. The top-level Service that we start and end with remains in the main test body, because its shape at the start and end is one of the main things that varies a lot between test cases. Updates #502.

David Anderson	8dbb3b8bbe	cmd/k8s-operator: remove unused structs. Cleanup missed in #6718 . Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	53a9cc76c7	cmd/k8s-operator: rename main.go -> operator.go. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	bc8f5a7734	cmd/k8s-operator: add a basic unit test. The test verifies one of the successful reconcile paths, where a client requests an exposed service via a LoadBalancer class. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	3b7ae39a06	cmd/k8s-operator: use the client's authkey method to create auth keys. Also introduces an intermediary interface for the tailscale client, in preparation for operator tests that fake out the Tailscale API interaction. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
David Anderson	b2d4abf25a	cmd/k8s-operator: add a kubernetes operator. This was initially developed in a separate repo, but for build/release reasons and because go module management limits the damage of importing k8s things now, moving it into this repo. At time of commit, the operator enables exposing services over tailscale, with the 'tailscale' loadBalancerClass. It also currently requires an unreleased feature to access the Tailscale API, so is not usable yet. Updates #502. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
