Irbe Krumina	cac290da87	cmd/k8s-operator: users can configure firewall mode for kube operator proxies (#9769 ) * cmd/k8s-operator: users can configure operator to set firewall mode for proxies Users can now pass PROXY_FIREWALL_MODE={nftables,auto,iptables} to operator to make it create ingress/egress proxies with that firewall mode Also makes sure that if an invalid firewall mode gets configured, the operator will not start provisioning proxy resources, but will instead log an error and write an error event to the related Service.

Maisem Ali	f53c3be07c	cmd/k8s-operator: use our own container image instead of busybox We already have sysctl in the `tailscale/tailscale` image, just use that. Updates #cleanup Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago

Irbe Krumina	fe709c81e5	cmd/k8s-operator,cmd/containerboot: add kube egress proxy (#9031 ) First part of work for the functionality that allows users to create an egress proxy to access Tailnet services from within Kubernetes cluster workloads. This PR allows creating an egress proxy that can access Tailscale services over HTTP only.

Maisem Ali	0c6fe94cf4	cmd/k8s-operator: add matching family addresses to status This was added in `3451b89e5f`, but resulted in the v6 Tailscale address being added to status when when the forwarding only happened on the v4 address.

Maisem Ali	c8dea67cbf	cmd/k8s-operator: add support for Ingress resources Previously, the operator would only monitor Services and create a Tailscale StatefulSet which acted as a L3 proxy which proxied traffic inbound to the Tailscale IP onto the services ClusterIP. This extends that functionality to also monitor Ingress resources where the `ingressClassName=tailscale` and similarly creates a Tailscale StatefulSet, acting as a L7 proxy instead. Users can override the desired hostname by setting: ``` - tls hosts: - "foo" ``` Hostnames specified under `rules` are ignored as we only create a single host. This is emitted as an event for users to see. Fixes #7895 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	12ac672542	cmd/k8s-operator: handle changes to services w/o teardown Previously users would have to unexpose/expose the service in order to change Hostname/TargetIP. This now applies those changes by causing a StatefulSet rollout now that `a61a9ab087` is in. Updates #502 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Brad Fitzpatrick	98a5116434	all: adjust some build tags for plan9 I'm not saying it works, but it compiles. Updates #5794 Change-Id: I2f3c99732e67fe57a05edb25b758d083417f083e Signed-off-by: Brad Fitzpatrick <bradfitz@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

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.

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.

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
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	53a9cc76c7	cmd/k8s-operator: rename main.go -> operator.go. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
