## Development setup
If you want to contribute to bug fixes or improve existing features, you have to ensure that all needed
dependencies are installed. Here is a short guide on how that can be done.
### Requirements
#### Go 1.21
Follow the installation guide from https://go.dev/
#### UI client - Fyne toolkit
We use the fyne toolkit in our UI client. You can follow its requirement guide to have all its dependencies installed: https://developer.fyne.io/started/#prerequisites
#### gRPC
You can follow the instructions from the quickstarter guide https://grpc.io/docs/languages/go/quickstart/#prerequisites and then run the `generate.sh` files located in each `proto` directory to generate changes.
> **IMPORTANT**: We are very open to contributions that can improve the client daemon protocol. For Signal and Management protocols, please reach out on slack or via github issues with your proposals.
#### Docker
Follow the installation guide from https://docs.docker.com/get-docker/
#### Goreleaser and golangci-lint
We utilize two tools in our Github actions workflows:
- Goreleaser: Used for release packaging. You can follow the installation steps [here](https://goreleaser.com/install/); keep in mind to match the version defined in [release.yml](/.github/workflows/release.yml)
- golangci-lint: Used for linting checks. You can follow the installation steps [here](https://golangci-lint.run/usage/install/); keep in mind to match the version defined in [golangci-lint.yml](/.github/workflows/golangci-lint.yml)
They can be executed from the repository root before every push or PR:
**Goreleaser**
```shell
goreleaser build --snapshot --clean
```
**golangci-lint**
```shell
golangci-lint run
```
### Local NetBird setup
> **IMPORTANT**: All the steps below have to get executed at least once to get the development setup up and running!
Now that everything NetBird requires to run is installed, the actual NetBird code can be
checked out and set up:
1. [Fork](https://guides.github.com/activities/forking/#fork) the NetBird repository
2. Clone your forked repository
```
git clone https://github.com/<your_github_username>/netbird.git
```
3. Go into the repository folder
```
cd netbird
```
4. Add the original NetBird repository as `upstream` to your forked repository
```
git remote add upstream https://github.com/netbirdio/netbird.git
```
5. Install all Go dependencies:
```
go mod tidy
```
### Dev Container Support
If you prefer using a dev container for development, NetBird now includes support for dev containers.
Dev containers provide a consistent and isolated development environment, making it easier for contributors to get started quickly. Follow the steps below to set up NetBird in a dev container.
#### 1. Prerequisites:
* Install Docker on your machine: [Docker Installation Guide](https://docs.docker.com/get-docker/)
* Install Visual Studio Code: [VS Code Installation Guide](https://code.visualstudio.com/download)
* If you prefer JetBrains Goland please follow this [manual](https://www.jetbrains.com/help/go/connect-to-devcontainer.html)
#### 2. Clone the Repository:
Clone the repository following previous [Local NetBird setup](#local-netbird-setup).
#### 3. Open in project in IDE of your choice:
**VScode**:
Open the project folder in Visual Studio Code:
```bash
code .
```
When you open the project in VS Code, it will detect the presence of a dev container configuration.
Click on the green "Reopen in Container" button in the bottom-right corner of VS Code.
**Goland**:
Open GoLand and select `"File" > "Open"` to open the NetBird project folder.
GoLand will detect the dev container configuration and prompt you to open the project in the container. Accept the prompt.
#### 4. Wait for the Container to Build:
VsCode or GoLand will use the specified Docker image to build the dev container. This might take some time, depending on your internet connection.
#### 6. Development:
Once the container is built, you can start developing within the dev container. All the necessary dependencies and configurations are set up within the container.
### Build and start
#### Client
To start NetBird, execute:
```
cd client
CGO_ENABLED=0 go build .
```
> Windows clients have a Wireguard driver requirement. You can download the wintun driver from https://www.wintun.net/builds/wintun-0.14.1.zip, after decompressing, you can copy the file `windtun\bin\ARCH\wintun.dll` to the same path as your binary file or to `C:\Windows\System32\wintun.dll`.
> To test the client GUI application on Windows machines with RDP or vituralized environments (e.g. virtualbox or cloud), you need to download and extract the opengl32.dll from https://fdossena.com/?p=mesa/index.frag next to the built application.
To start NetBird the client in the foreground:
```
sudo ./client up --log-level debug --log-file console
```
> On Windows use a powershell with administrator privileges
#### Signal service
To start NetBird's signal, execute:
```
cd signal
go build .
```
To start NetBird the signal service:
```
./signal run --log-level debug --log-file console
```
#### Management service
> You may need to generate a configuration file for management. Follow steps 2 to 5 from our [self-hosting guide](https://netbird.io/docs/getting-started/self-hosting).
To start NetBird's management, execute:
```
cd management
go build .
```
To start NetBird the management service:
```
./management management --log-level debug --log-file console --config ./management.json
```
#### Windows Netbird Installer
Create dist directory
```shell
mkdir -p dist/netbird_windows_amd64
```
UI client

## Checklist before submitting a PR
As a critical network service and open-source project, we must enforce a few things before submitting the pull-requests:
- Keep functions as simple as possible, with a single purpose
- Use private functions and constants where possible
- Comment on any new public functions
- Add unit tests for any new public function
> When pushing fixes to the PR comments, please push as separate commits; we will squash the PR before merging, so there is no need to squash it before pushing it, and we are more than okay with 10-100 commits in a single PR. This helps review the fixes to the requested changes.
## Other project repositories
NetBird project is composed of 3 main repositories:
- NetBird: This repository, which contains the code for the agents and control plane services.
- Dashboard: https://github.com/netbirdio/dashboard, contains the Administration UI for the management service
- Documentations: https://github.com/netbirdio/docs, contains the documentation from https://netbird.io/docs
## Contributor License Agreement
That we do not have any potential problems later it is sadly necessary to sign a [Contributor License Agreement](CONTRIBUTOR_LICENSE_AGREEMENT.md). That can be done literally with the push of a button.
A bot will automatically comment on the pull request once it got opened asking for the agreement to be signed. Before it did not get signed it is sadly not possible to merge it in.

# Contributor License Agreement
We are incredibly thankful for the contributions we receive from the community.
We require our external contributors to sign a Contributor License Agreement ("CLA") in
order to ensure that our projects remain licensed under Free and Open Source licenses such
as BSD-3 while allowing Wiretrustee to build a sustainable business.
Wiretrustee is committed to having a true Open Source Software ("OSS") license for
our software. A CLA enables Wiretrustee to safely commercialize our products
while keeping a standard OSS license with all the rights that license grants to users: the
ability to use the project in their own projects or businesses, to republish modified
source, or to completely fork the project.
This page gives a human-friendly summary of our CLA, details on why we require a CLA, how
contributors can sign our CLA, and more. You may view the full legal CLA document (below).
# Human-friendly summary
This is a human-readable summary of (and not a substitute for) the full agreement (below).
This highlights only some of key terms of the CLA. It has no legal value and you should
carefully review all the terms of the actual CLA before agreeing.
<li>Grant of copyright license. You give Wiretrustee permission to use your copyrighted work
in commercial products.
</li>
<li>Grant of patent license. If your contributed work uses a patent, you give Wiretrustee a
license to use that patent including within commercial products. You also agree that you
have permission to grant this license.
</li>
<li>No Warranty or Support Obligations.
By making a contribution, you are not obligating yourself to provide support for the
contribution, and you are not taking on any warranty obligations or providing any
assurances about how it will perform.
</li>
The CLA does not change the terms of the standard open source license used by our software
such as BSD-3 or MIT.
You are still free to use our projects within your own projects or businesses, republish
modified source, and more.
Please reference the appropriate license for the project you're contributing to to learn
more.
# Why require a CLA?
Agreeing to a CLA explicitly states that you are entitled to provide a contribution, that you cannot withdraw permission
to use your contribution at a later date, and that Wiretrustee has permission to use your contribution in our commercial
products.
This removes any ambiguities or uncertainties caused by not having a CLA and allows users and customers to confidently
adopt our projects. At the same time, the CLA ensures that all contributions to our open source projects are licensed
under the project's respective open source license, such as BSD-3.
Requiring a CLA is a common and well-accepted practice in open source. Major open source projects require CLAs such as
Apache Software Foundation projects, Facebook projects (such as React), Google projects (including Go), Python, Django,
and more. Each of these projects remains licensed under permissive OSS licenses such as MIT, Apache, BSD, and more.
# Signing the CLA
Open a pull request ("PR") to any of our open source projects to sign the CLA. A bot will comment on the PR asking you
to sign the CLA if you haven't already.
Follow the steps given by the bot to sign the CLA. This will require you to log in with GitHub (we only request public
information from your account) and to fill in a few additional details such as your name and email address. We will only
use this information for CLA tracking; none of your submitted information will be used for marketing purposes.
You only have to sign the CLA once. Once you've signed the CLA, future contributions to any Wiretrustee project will not
require you to sign again.
# Legal Terms and Agreement
In order to clarify the intellectual property license granted with Contributions from any person or entity, Wiretrustee
UG (haftungsbeschränkt) ("Wiretrustee") must have a Contributor License Agreement ("CLA") on file that has been signed
by each Contributor, indicating agreement to the license terms below. This license does not change your rights to use
your own Contributions for any other purpose.
You accept and agree to the following terms and conditions for Your present and future Contributions submitted to
Wiretrustee. Except for the license granted herein to Wiretrustee and recipients of software distributed by Wiretrustee,
You reserve all right, title, and interest in and to Your Contributions.
1. Definitions.
```
"You" (or "Your") shall mean the copyright owner or legal entity authorized by the copyright owner
that is making this Agreement with Wiretrustee. For legal entities, the entity making a Contribution and all other
entities that control, are controlled by, or are under common control with that entity are considered
to be a single Contributor. For the purposes of this definition, "control" means (i) the power, direct or indirect,
to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty
percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
```
```
"Contribution" shall mean any original work of authorship, including any modifications or additions to
an existing work, that is or previously has been intentionally submitted by You to Wiretrustee for inclusion in,
or documentation of, any of the products owned or managed by Wiretrustee (the "Work").
For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication
sent to Wiretrustee or its representatives, including but not limited to communication on electronic mailing lists,
source code control systems, and issue tracking systems that are managed by, or on behalf of,
Wiretrustee for the purpose of discussing and improving the Work, but excluding communication that is conspicuously
marked or otherwise designated in writing by You as "Not a Contribution."
```
2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Wiretrustee
and to recipients of software distributed by Wiretrustee a perpetual, worldwide, non-exclusive, no-charge,
royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly
perform, sublicense, and distribute Your Contributions and such derivative works.
3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Wiretrustee and
to recipients of software distributed by Wiretrustee a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import,
and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are
necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which
such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (
including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have
contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity
under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
4. You represent that you are legally entitled to grant the above license. If your employer(s) has rights to
intellectual property that you create that includes your Contributions, you represent that you have received
permission to make Contributions on behalf of that employer, that you will have received permission from your current
and future employers for all future Contributions, that your applicable employer has waived such rights for all of
your current and future Contributions to Wiretrustee, or that your employer has executed a separate Corporate CLA
with Wiretrustee.
5. You represent that each of Your Contributions is Your original creation (see section 7 for submissions on behalf of
others). You represent that Your Contribution submissions include complete details of any third-party license or
other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware
and which are associated with any part of Your Contributions.
6. You are not expected to provide support for Your Contributions, except to the extent You desire to provide support.
You may provide support for free, for a fee, or not at all. Unless required by applicable law or agreed to in
writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either
express or implied, including, without limitation, any warranties or conditions of TITLE, NON- INFRINGEMENT,
MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.
7. Should You wish to submit work that is not Your original creation, You may submit it to Wiretrustee separately from
any Contribution, identifying the complete details of its source and of any license or other restriction (including,
but not limited to, related patents, trademarks, and license agreements) of which you are personally aware, and
conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".
8. You agree to notify Wiretrustee of any facts or circumstances of which you become aware that would make these
representations inaccurate in any respect.

### Quickstart with NetBird Cloud
- Download and install NetBird at [https://app.netbird.io/install](https://app.netbird.io/install)
- Follow the steps to sign-up with Google, Microsoft, GitHub or your email address.
- Check NetBird [admin UI](https://app.netbird.io/).
- Add more machines.
### Quickstart with self-hosted NetBird
> This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM.
Follow the [Advanced guide with a custom identity provider](https://docs.netbird.io/selfhosted/selfhosted-guide#advanced-guide-with-a-custom-identity-provider) for installations with different IDPs.
**Infrastructure requirements:**
- A Linux VM with at least **1CPU** and **2GB** of memory.
- The VM should be publicly accessible on TCP ports **80** and **443** and UDP ports: **3478**, **49152-65535**.
- **Public domain** name pointing to the VM.
**Software requirements:**
- Docker installed on the VM with the docker-compose plugin ([Docker installation guide](https://docs.docker.com/engine/install/)) or docker with docker-compose in version 2 or higher.
- [jq](https://jqlang.github.io/jq/) installed. In most distributions
Usually available in the official repositories and can be installed with `sudo apt install jq` or `sudo yum install jq`
- [curl](https://curl.se/) installed.
Usually available in the official repositories and can be installed with `sudo apt install curl` or `sudo yum install curl`
**Steps**
- Download and run the installation script:
```bash
export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started-with-zitadel.sh | bash
```
- Once finished, you can manage the resources via `docker-compose`
### A bit on NetBird internals
- Every machine in the network runs [NetBird Agent (or Client)](client/) that manages WireGuard.
- Every agent connects to [Management Service](management/) that holds network state, manages peer IPs, and distributes network updates to agents (peers).
- NetBird agent uses WebRTC ICE implemented in [pion/ice library](https://github.com/pion/ice) to discover connection candidates when establishing a peer-to-peer connection between machines.
- Connection candidates are discovered with the help of [STUN](https://en.wikipedia.org/wiki/STUN) servers.
- Agents negotiate a connection through [Signal Service](signal/) passing p2p encrypted messages with candidates.
- Sometimes the NAT traversal is unsuccessful due to strict NATs (e.g. mobile carrier-grade NAT) and a p2p connection isn't possible. When this occurs the system falls back to a relay server called [TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT), and a secure WireGuard tunnel is established via the TURN server.

[Coturn](https://github.com/coturn/coturn) is the one that has been successfully used for STUN and TURN in NetBird setups.
