# CHANGELOG
## Next
## 0.25.0 (2025-02-xx)
## 0.17.0 (2022-XX-XX)
### BREAKING
- Authentication flow has been rewritten
[#2374](https://github.com/juanfont/headscale/pull/2374) This change should be
transparent to users with the exception of some buxfixes that has been
discovered and was fixed as part of the rewrite.
- When a node is registered with _a new user_, it will be registered as a new
node ([#2327](https://github.com/juanfont/headscale/issues/2327) and
[#1310](https://github.com/juanfont/headscale/issues/1310)).
- A logged out node logging in with the same user will replace the existing
node.

## 0.24.0 (2025-01-17)
### Security fix: OIDC changes in Headscale 0.24.0
The following issue _only_ affects Headscale installations which authenticate
with OIDC.
_Headscale v0.23.0 and earlier_ identified OIDC users by the "username" part of
their email address (when `strip_email_domain: true`, the default) or whole
email address (when `strip_email_domain: false`).
Depending on how Headscale and your Identity Provider (IdP) were configured,
only using the `email` claim could allow a malicious user with an IdP account to
take over another Headscale user's account, even when
`strip_email_domain: false`.
This would also cause a user to lose access to their Headscale account if they
changed their email address.
_Headscale v0.24.0_ now identifies OIDC users by the `iss` and `sub` claims.
[These are guaranteed by the OIDC specification to be stable and unique](https://openid.net/specs/openid-connect-core-1_0.html#ClaimStability),
even if a user changes email address. A well-designed IdP will typically set
`sub` to an opaque identifier like a UUID or numeric ID, which has no relation
to the user's name or email address.
Headscale v0.24.0 and later will also automatically update profile fields with
OIDC data on login. This means that users can change those details in your IdP,
and have it populate to Headscale automatically the next time they log in.
However, this may affect the way you reference users in policies.
Headscale v0.23.0 and earlier never recorded the `iss` and `sub` fields, so all
legacy (existing) OIDC accounts _need to be migrated_ to be properly secured.
#### What do I need to do to migrate?
Headscale v0.24.0 has an automatic migration feature, which is enabled by
default (`map_legacy_users: true`). **This will be disabled by default in a
future version of Headscale any unmigrated users will get new accounts.**
The migration will mostly be done automatically, with one exception. If your
OIDC does not provide an `email_verified` claim, Headscale will ignore the
`email`. This means that either the administrator will have to mark the user
emails as verified, or ensure the users verify their emails. Any unverified
emails will be ignored, meaning that the users will get new accounts instead of
being migrated.
After this exception is ensured, make all users log into Headscale with their
account, and Headscale will automatically update the account record. This will
be transparent to the users.
When all users have logged in, you can disable the automatic migration by
setting `map_legacy_users: false` in your configuration file.
Please note that `map_legacy_users` will be set to `false` by default in v0.25.0
and the migration mechanism will be removed in v0.26.0.
<details>
<summary>What does automatic migration do?</summary>
##### What does automatic migration do?
When automatic migration is enabled (`map_legacy_users: true`), Headscale will
first match an OIDC account to a Headscale account by `iss` and `sub`, and then
fall back to matching OIDC users similarly to how Headscale v0.23.0 did:
- If `strip_email_domain: true` (the default): the Headscale username matches
the "username" part of their email address.
- If `strip_email_domain: false`: the Headscale username matches the _whole_
email address.
On migration, Headscale will change the account's username to their
`preferred_username`. **This could break any ACLs or policies which are
configured to match by username.**
Like with Headscale v0.23.0 and earlier, this migration only works for users who
haven't changed their email address since their last Headscale login.
A _successful_ automated migration should otherwise be transparent to users.
Once a Headscale account has been migrated, it will be _unavailable_ to be
matched by the legacy process. An OIDC login with a matching username, but
_non-matching_ `iss` and `sub` will instead get a _new_ Headscale account.
Because of the way OIDC works, Headscale's automated migration process can
_only_ work when a user tries to log in after the update.
Legacy account migration should have no effect on new installations where all
users have a recorded `sub` and `iss`.
</details>
<details>
<summary>What happens when automatic migration is disabled?</summary>
##### What happens when automatic migration is disabled?
When automatic migration is disabled (`map_legacy_users: false`), Headscale will
only try to match an OIDC account to a Headscale account by `iss` and `sub`.
If there is no match, it will get a _new_ Headscale account even if there was
a legacy account which _could_ have matched and migrated.
We recommend new Headscale users explicitly disable automatic migration but it
should otherwise have no effect if every account has a recorded `iss` and `sub`.
When automatic migration is disabled, the `strip_email_domain` setting will have
no effect.
</details>
Special thanks to @micolous for reviewing, proposing and working with us on
these changes.
#### Other OIDC changes
Headscale now uses
[the standard OIDC claims](https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims)
to populate and update user information every time they log in:
| Headscale profile field | OIDC claim | Notes / examples |
| ----------------------- | -------------------- | --------------------------------------------------------------------------------------------------------- |
| email address | `email` | Only used when `"email_verified": true` |
| display name | `name` | eg: `Sam Smith` |
| username | `preferred_username` | Varies depending on IdP and configuration, eg: `ssmith`, `ssmith@idp.example.com`, `\\example.com\ssmith` |
| profile picture | `picture` | URL to a profile picture or avatar |
These should show up nicely in the Tailscale client.
This will also affect the way you
[reference users in policies](https://github.com/juanfont/headscale/pull/2205).

## 0.23.0 (2024-09-18)
This release was intended to be mainly a code reorganisation and refactoring,
significantly improving the maintainability of the codebase. This should allow
us to improve further and make it easier for the maintainers to keep on top of
the project. However, as you all have noticed, it turned out to become a much
larger, much longer release cycle than anticipated. It has ended up to be a
release with a lot of rewrites and changes to the code base and functionality of
Headscale, cleaning up a lot of technical debt and introducing a lot of
improvements. This does come with some breaking changes,
**Please remember to always back up your database between versions**
#### Here is a short summary of the broad topics of changes:
Code has been organised into modules, reducing use of global variables/objects,
isolating concerns and “putting the right things in the logical place”.
The new
[policy](https://github.com/juanfont/headscale/tree/main/hscontrol/policy) and
[mapper](https://github.com/juanfont/headscale/tree/main/hscontrol/mapper)
package, containing the ACL/Policy logic and the logic for creating the data
served to clients (the network “map”) has been rewritten and improved. This
change has allowed us to finish SSH support and add additional tests throughout
the code to ensure correctness.
The
[“poller”, or streaming logic](https://github.com/juanfont/headscale/blob/main/hscontrol/poll.go)
has been rewritten and instead of keeping track of the latest updates, checking
at a fixed interval, it now uses go channels, implemented in our new
[notifier](https://github.com/juanfont/headscale/tree/main/hscontrol/notifier)
package and it allows us to send updates to connected clients immediately. This
should both improve performance and potential latency before a client picks up
an update.
Headscale now supports sending “delta” updates, thanks to the new mapper and
poller logic, allowing us to only inform nodes about new nodes, changed nodes
and removed nodes. Previously we sent the entire state of the network every time
an update was due.
While we have a pretty good
[test harness](https://github.com/search?q=repo%3Ajuanfont%2Fheadscale+path%3A_test.go&type=code)
for validating our changes, the changes came down to
[284 changed files with 32,316 additions and 24,245 deletions](https://github.com/juanfont/headscale/compare/b01f1f1867136d9b2d7b1392776eb363b482c525...ed78ecd)
and bugs are expected. We need help testing this release. In addition, while we
think the performance should in general be better, there might be regressions in
parts of the platform, particularly where we prioritised correctness over speed.
There are also several bugfixes that has been encountered and fixed as part of
implementing these changes, particularly after improving the test harness as
part of adopting [#1460](https://github.com/juanfont/headscale/pull/1460).
### BREAKING
- Code reorganisation, a lot of code has moved, please review the following PRs
accordingly [#1473](https://github.com/juanfont/headscale/pull/1473)
- Change the structure of database configuration, see
[config-example.yaml](./config-example.yaml) for the new structure.
[#1700](https://github.com/juanfont/headscale/pull/1700)
- Old structure has been remove and the configuration _must_ be converted.
- Adds additional configuration for PostgreSQL for setting max open, idle
connection and idle connection lifetime.
- API: Machine is now Node
[#1553](https://github.com/juanfont/headscale/pull/1553)
- Remove support for older Tailscale clients
[#1611](https://github.com/juanfont/headscale/pull/1611)
- The oldest supported client is 1.42
- Headscale checks that _at least_ one DERP is defined at start
[#1564](https://github.com/juanfont/headscale/pull/1564)
- If no DERP is configured, the server will fail to start, this can be because
it cannot load the DERPMap from file or url.
- Embedded DERP server requires a private key
[#1611](https://github.com/juanfont/headscale/pull/1611)
- Add a filepath entry to
[`derp.server.private_key_path`](https://github.com/juanfont/headscale/blob/b35993981297e18393706b2c963d6db882bba6aa/config-example.yaml#L95)
- Docker images are now built with goreleaser (ko)
[#1716](https://github.com/juanfont/headscale/pull/1716)
[#1763](https://github.com/juanfont/headscale/pull/1763)
- Entrypoint of container image has changed from shell to headscale, require
change from `headscale serve` to `serve`
- `/var/lib/headscale` and `/var/run/headscale` is no longer created
automatically, see [container docs](./docs/setup/install/container.md)
- Prefixes are now defined per v4 and v6 range.
[#1756](https://github.com/juanfont/headscale/pull/1756)
- `ip_prefixes` option is now `prefixes.v4` and `prefixes.v6`
- `prefixes.allocation` can be set to assign IPs at `sequential` or `random`.
[#1869](https://github.com/juanfont/headscale/pull/1869)
- MagicDNS domains no longer contain usernames []()
- This is in preparation to fix Headscales implementation of tags which
currently does not correctly remove the link between a tagged device and a
user. As tagged devices will not have a user, this will require a change to
the DNS generation, removing the username, see
[#1369](https://github.com/juanfont/headscale/issues/1369) for more
information.
- `use_username_in_magic_dns` can be used to turn this behaviour on again, but
note that this option _will be removed_ when tags are fixed.
- dns.base_domain can no longer be the same as (or part of) server_url.
- This option brings Headscales behaviour in line with Tailscale.
- YAML files are no longer supported for headscale policy.
[#1792](https://github.com/juanfont/headscale/pull/1792)
- HuJSON is now the only supported format for policy.
- DNS configuration has been restructured
[#2034](https://github.com/juanfont/headscale/pull/2034)
- Please review the new [config-example.yaml](./config-example.yaml) for the
new structure.

- Please note that this support should be considered _partially_ implemented
- SSH ACLs status:
- Support `accept` and `check` (SSH can be enabled and used for connecting
and authentication)
- Rejecting connections **are not supported**, meaning that if you enable
SSH, then assume that _all_ `ssh` connections **will be allowed**.
- If you decided to try this feature, please carefully managed permissions
by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your
clients.

# Contributing
Headscale is "Open Source, acknowledged contribution", this means that any contribution will have to be discussed with the maintainers before being added to the project.
This model has been chosen to reduce the risk of burnout by limiting the maintenance overhead of reviewing and validating third-party code.
## Why do we have this model?
Headscale has a small maintainer team that tries to balance working on the project, fixing bugs and reviewing contributions.
When we work on issues ourselves, we develop first hand knowledge of the code and it makes it possible for us to maintain and own the code as the project develops.
Code contributions are seen as a positive thing. People enjoy and engage with our project, but it also comes with some challenges; we have to understand the code, we have to understand the feature, we might have to become familiar with external libraries or services and we think about security implications. All those steps are required during the reviewing process. After the code has been merged, the feature has to be maintained. Any changes reliant on external services must be updated and expanded accordingly.
The review and day-1 maintenance adds a significant burden on the maintainers. Often we hope that the contributor will help out, but we found that most of the time, they disappear after their new feature was added.
This means that when someone contributes, we are mostly happy about it, but we do have to run it through a series of checks to establish if we actually can maintain this feature.
## What do we require?
A general description is provided here and an explicit list is provided in our pull request template.
All new features have to start out with a design document, which should be discussed on the issue tracker (not discord). It should include a use case for the feature, how it can be implemented, who will implement it and a plan for maintaining it.
All features have to be end-to-end tested (integration tests) and have good unit test coverage to ensure that they work as expected. This will also ensure that the feature continues to work as expected over time. If a change cannot be tested, a strong case for why this is not possible needs to be presented.
The contributor should help to maintain the feature over time. In case the feature is not maintained probably, the maintainers reserve themselves the right to remove features they redeem as unmaintainable. This should help to improve the quality of the software and keep it in a maintainable state.
## Bug fixes
Headscale is open to code contributions for bug fixes without discussion.
## Documentation
If you find mistakes in the documentation, please submit a fix to the documentation.

## Design goal
Headscale aims to implement a self-hosted, open source alternative to the
[Tailscale](https://tailscale.com/) control server. Headscale's goal is to
provide self-hosters and hobbyists with an open-source server they can use for
their projects and labs. It implements a narrow scope, a _single_ Tailscale
network (tailnet), suitable for a personal use, or a small open-source
organisation.
`headscale` aims to implement a self-hosted, open source alternative to the Tailscale
control server. `headscale` has a narrower scope and an instance of `headscale`
implements a _single_ Tailnet, which is typically what a single organisation, or
home/personal setup would use.
## Supporting Headscale
`headscale` uses terms that maps to Tailscale's control server, consult the
[glossary](./docs/glossary.md) for explainations.
## Support
If you like `headscale` and find it useful, there is a sponsorship and donation
buttons available in the repo.
If you would like to sponsor features, bugs or prioritisation, reach out to
one of the maintainers.
## Features
Please see ["Features" in the documentation](https://headscale.net/stable/about/features/).
- Full "base" support of Tailscale's features
- Configurable DNS
- [Split DNS](https://tailscale.com/kb/1054/dns/#using-dns-settings-in-the-admin-console)
- Node registration
- Single-Sign-On (via Open ID Connect)
- Pre authenticated key
- Taildrop (File Sharing)
- [Access control lists](https://tailscale.com/kb/1018/acls/)
- [MagicDNS](https://tailscale.com/kb/1081/magicdns)
- Support for multiple IP ranges in the tailnet
- Dual stack (IPv4 and IPv6)
- Routing advertising (including exit nodes)
- Ephemeral nodes
- Embedded [DERP server](https://tailscale.com/blog/how-tailscale-works/#encrypted-tcp-relays-derp)
## Client OS support
Please see ["Client and operating system support" in the documentation](https://headscale.net/stable/about/clients/).
| OS | Supports headscale |
| ------- | --------------------------------------------------------- |
| Linux | Yes |
| OpenBSD | Yes |
| FreeBSD | Yes |
| macOS | Yes (see `/apple` on your headscale for more information) |
| Windows | Yes [docs](./docs/windows-client.md) |
| Android | Yes [docs](./docs/android-client.md) |
| iOS | Not yet |
## Running headscale
**Please note that we do not support nor encourage the use of reverse proxies
and container to run Headscale.**
Please have a look at the [`documentation`](https://headscale.net/stable/).
## Talks
- Fosdem 2023 (video): [Headscale: How we are using integration testing to reimplement Tailscale](https://fosdem.org/2023/schedule/event/goheadscale/)
- presented by Juan Font Alonso and Kristoffer Dalby
Please have a look at the documentation under [`docs/`](docs/).
## Disclaimer
This project is not associated with Tailscale Inc.
However, one of the active maintainers for Headscale [is employed by Tailscale](https://tailscale.com/blog/opensource) and he is allowed to spend work hours contributing to the project. Contributions from this maintainer are reviewed by other maintainers.
The maintainers work together on setting the direction for the project. The underlying principle is to serve the community of self-hosters, enthusiasts and hobbyists - while having a sustainable project.
1. We have nothing to do with Tailscale, or Tailscale Inc.
2. The purpose of Headscale is maintaining a working, self-hosted Tailscale control panel.
## Contributing
Please read the [CONTRIBUTING.md](./CONTRIBUTING.md) file.
### Requirements
To contribute to headscale you would need the latest version of [Go](https://golang.org)
and [Buf](https://buf.build) (Protobuf generator).
To contribute to headscale you would need the lastest version of [Go](https://golang.org)
and [Buf](https://buf.build)(Protobuf generator).
We recommend using [Nix](https://nixos.org/) to setup a development environment. This can
be done with `nix develop`, which will install the tools and give you a shell.
This guarantees that you will have the same dev env as `headscale` maintainers.
PRs and suggestions are welcome.

# headscale documentation
This page contains the official and community contributed documentation for `headscale`.
If you are having trouble with following the documentation or get unexpected results,
please ask on [Discord](https://discord.gg/c84AZQhmpx) instead of opening an Issue.
## Official documentation
### How-to
- [Running headscale on Linux](running-headscale-linux.md)
- [Control headscale remotely](remote-cli.md)
- [Using a Windows client with headscale](windows-client.md)
### References
- [Configuration](../config-example.yaml)
- [Glossary](glossary.md)
- [TLS](tls.md)
## Community documentation
Community documentation is not actively maintained by the headscale authors and is
written by community members. It is _not_ verified by `headscale` developers.
**It might be outdated and it might miss necessary steps**.
- [Running headscale in a container](running-headscale-container.md)
- [Running headscale on OpenBSD](running-headscale-openbsd.md)
- [Running headscale behind a reverse proxy](reverse-proxy.md)
## Misc
### Policy ACLs
Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
For instance, instead of referring to users when defining groups you must
use namespaces (which are the equivalent to user/logins in Tailscale.com).
Please check https://tailscale.com/kb/1018/acls/, and `./tests/acls/` in this repo for working examples.
When using ACL's the Namespace borders are no longer applied. All machines
whichever the Namespace have the ability to communicate with other hosts as
long as the ACL's permits this exchange.
The [ACLs](acls.md) document should help understand a fictional case of setting
up ACLs in a small company. All concepts presented in this document could be
applied outside of business oriented usage.
### Apple devices
An endpoint with information on how to connect your Apple devices (currently macOS only) is available at `/apple` on your running instance.

# Frequently Asked Questions
## What is the design goal of headscale?
Headscale aims to implement a self-hosted, open source alternative to the
[Tailscale](https://tailscale.com/) control server. Headscale's goal is to
provide self-hosters and hobbyists with an open-source server they can use for
their projects and labs. It implements a narrow scope, a _single_ Tailscale
network (tailnet), suitable for a personal use, or a small open-source
organisation.
## How can I contribute?
Headscale is "Open Source, acknowledged contribution", this means that any
contribution will have to be discussed with the Maintainers before being submitted.
Please see [Contributing](contributing.md) for more information.
## Why is 'acknowledged contribution' the chosen model?
Both maintainers have full-time jobs and families, and we want to avoid burnout. We also want to avoid frustration from contributors when their PRs are not accepted.
We are more than happy to exchange emails, or to have dedicated calls before a PR is submitted.
## When/Why is Feature X going to be implemented?
We don't know. We might be working on it. If you're interested in contributing, please post a feature request about it.
Please be aware that there are a number of reasons why we might not accept specific contributions:
- It is not possible to implement the feature in a way that makes sense in a self-hosted environment.
- Given that we are reverse-engineering Tailscale to satisfy our own curiosity, we might be interested in implementing the feature ourselves.
- You are not sending unit and integration tests with it.
## Do you support Y method of deploying headscale?
We currently support deploying headscale using our binaries and the DEB packages. Visit our [installation guide using
official releases](../setup/install/official.md) for more information.
In addition to that, you may use packages provided by the community or from distributions. Learn more in the
[installation guide using community packages](../setup/install/community.md).
For convenience, we also [build Docker images with headscale](../setup/install/container.md). But **please be aware that
we don't officially support deploying headscale using Docker**. On our [Discord server](https://discord.gg/c84AZQhmpx)
we have a "docker-issues" channel where you can ask for Docker-specific help to the community.
## Which database should I use?
We recommend the use of SQLite as database for headscale:
- SQLite is simple to setup and easy to use
- It scales well for all of headscale's usecases
- Development and testing happens primarily on SQLite
- PostgreSQL is still supported, but is considered to be in "maintenance mode"
The headscale project itself does not provide a tool to migrate from PostgreSQL to SQLite. Please have a look at [the
related tools documentation](../ref/integration/tools.md) for migration tooling provided by the community.
## Why is my reverse proxy not working with headscale?
We don't know. We don't use reverse proxies with headscale ourselves, so we don't have any experience with them. We have
[community documentation](../ref/integration/reverse-proxy.md) on how to configure various reverse proxies, and a
dedicated "reverse-proxy-issues" channel on our [Discord server](https://discord.gg/c84AZQhmpx) where you can ask for
help to the community.
## Can I use headscale and tailscale on the same machine?
Running headscale on a machine that is also in the tailnet can cause problems with subnet routers, traffic relay nodes, and MagicDNS. It might work, but it is not supported.

## ACL setup
ACLs have to be written in [huJSON](https://github.com/tailscale/hujson).
Note: Namespaces will be created automatically when users authenticate with the
Headscale server.
When [registering the servers](../usage/getting-started.md#register-a-node) we
will need to add the flag `--advertise-tags=tag:<tag1>,tag:<tag2>`, and the user
that is registering the server should be allowed to do it. Since anyone can add
tags to a server they can register, the check of the tags is done on headscale
server and only valid tags are applied. A tag is valid if the user that is

To use ACLs in headscale, you must edit your `config.yaml` file. In there you will find a `policy.path` parameter. This
will need to point to your ACL file. More info on how these policies are written can be found
[here](https://tailscale.com/kb/1018/acls/).
Please reload or restart Headscale after updating the ACL file. Headscale may be reloaded either via its systemd service
(`sudo systemctl reload headscale`) or by sending a SIGHUP signal (`sudo kill -HUP $(pidof headscale)`) to the main
process. Headscale logs the result of ACL policy processing after each reload.

# Connecting an Android client
## Goal
This documentation has the goal of showing how a user can use the official Android [Tailscale](https://tailscale.com) client with `headscale`.
## Installation
Install the official Tailscale Android client from the [Google Play Store](https://play.google.com/store/apps/details?id=com.tailscale.ipn) or [F-Droid](https://f-droid.org/packages/com.tailscale.ipn/).
Ensure that the installed version is at least 1.30.0, as that is the first release to support custom URLs.
## Configuring the headscale URL
After opening the app, the kebab menu icon (three dots) on the top bar on the right must be repeatedly opened and closed until the _Change server_ option appears in the menu. This is where you can enter your headscale URL.
A screen recording of this process can be seen in the `tailscale-android` PR which implemented this functionality: <https://github.com/tailscale/tailscale-android/pull/55>
After saving and restarting the app, selecting the regular _Sign in_ option (non-SSO) should open up the headscale authentication page.

# Deploying headscale on Kubernetes
**Note:** This is contributed by the community and not verified by the headscale authors.
This directory contains [Kustomize](https://kustomize.io) templates that deploy
headscale in various configurations.
These templates currently support Rancher k3s. Other clusters may require
adaptation, especially around volume claims and ingress.
Commands below assume this directory is your current working directory.
# Generate secrets and site configuration
Run `./init.bash` to generate keys, passwords, and site configuration files.
Edit `base/site/public.env`, changing `public-hostname` to the public DNS name
that will be used for your headscale deployment.
Set `public-proto` to "https" if you're planning to use TLS & Let's Encrypt.
Configure DERP servers by editing `base/site/derp.yaml` if needed.
# Add the image to the registry
You'll somehow need to get `headscale:latest` into your cluster image registry.
An easy way to do this with k3s:
- Reconfigure k3s to use docker instead of containerd (`k3s server --docker`)
- `docker build -t headscale:latest ..` from here
# Create the namespace
If it doesn't already exist, `kubectl create ns headscale`.
# Deploy headscale
## sqlite
`kubectl -n headscale apply -k ./sqlite`
## postgres
`kubectl -n headscale apply -k ./postgres`
# TLS & Let's Encrypt
Test a staging certificate with your configured DNS name and Let's Encrypt.
`kubectl -n headscale apply -k ./staging-tls`
Replace with a production certificate.
`kubectl -n headscale apply -k ./production-tls`
## Static / custom TLS certificates
Only Let's Encrypt is supported. If you need other TLS settings, modify or patch the ingress.
# Administration
Use the wrapper script to remotely operate headscale to perform administrative
tasks like creating namespaces, authkeys, etc.
```
[c@nix-slate:~/Projects/headscale/k8s]$ ./headscale.bash
headscale is an open source implementation of the Tailscale control server
https://github.com/juanfont/headscale
Usage:
headscale [command]
Available Commands:
help Help about any command
namespace Manage the namespaces of headscale
node Manage the nodes of headscale
preauthkey Handle the preauthkeys in headscale
routes Manage the routes of headscale
serve Launches the headscale server
version Print the version.
Flags:
-h, --help help for headscale
-o, --output string Output format. Empty for human-readable, 'json' or 'json-line'
Use "headscale [command] --help" for more information about a command.
```
# TODO / Ideas
- Interpolate `email:` option to the ClusterIssuer from site configuration.
This probably needs to be done with a transformer, kustomize vars don't seem to work.
- Add kustomize examples for cloud-native ingress, load balancer
- CockroachDB for the backend
- DERP server deployment
- Tor hidden service
