Installation Using Solar System Orchestrator (Recommended, Docker) 🚀

If you are planning to host your own instance of Sunrise, please highly consider using the Solar System orchestrator.

It includes Sunrise and other all required services for a fully functional Sunrise server. As a bonus, it also includes a website and a Discord bot!

This is the recommended way to set up your Sunrise server without the need to manually set up each service.

If you are looking for the official documentation, please refer to docs.sunrize.uk.

Standalone installation with self-signed certificate (Docker) 🐳

1. Clone the repository
2. Open the project's folder in any CLI environment.
3. Set up production environment

   • Create the file Sunrise.Server/appsettings.Production.json and fill it following the Sunrise.Server/appsettings.Production.json.example example.

     cp Sunrise.Server/appsettings.Production.json.example Sunrise.Server/appsettings.Production.json
     

   • Set the environment variables in the .env file.

     cp .env.example .env
     

[!WARNING] Make sure to update WEB_DOMAIN and API_TOKEN_SECRET values!

4. Set up the beatmap manager by following the instructions in the Observatory repository. After setting up the beatmap manager, you need to set the General:ObservatoryUrl in the Sunrise.Server/appsettings.Production.json file to the address of the beatmap manager.
   • NB: Make sure that the PORT is defined properly (sunrise checks port 3333 by default) and POSTGRES_PORT value doesn't conflict with other PC ports.
5. ⚠️ Please create sunrise.pfx file and move it to Sunrise/sunrise.pfx folder, for more instructions follow Local connection ⚙️.
6. Start server by running:

   docker compose -f docker-compose.yml up -d
   

7. (Optional) If you want to connect to the server locally, please refer to the Local connection ⚙️ section.

[!TIP] Your final docker setup should look like this:

Development installation ⚒️

1. Clone the repository
2. Open the project's folder in any CLI environment.
3. Set up development environment by running:

   docker compose -f docker-compose.dev.yml up -d
   

4. Set up the beatmap manager by following the instructions in the Observatory repository. After setting up the beatmap manager, you need to set the General:ObservatoryUrl in the Sunrise.Server/appsettings.{Your Environment}.json file to the address of the beatmap manager.
   • NB: Make sure that the PORT is defined properly (sunrise checks port 3333 by default) and POSTGRES_PORT value doesn't conflict with other PC ports.
5. ⚠️ Please create sunrise.pfx file and move it to Sunrise/sunrise.pfx folder, for more instructions follow Local connection ⚙️.
6. Run the project
7. (Optional) If you want to connect to the server locally, please refer to the Local connection ⚙️ section.

Local connection ⚙️

If you want to connect to the server locally, follow these steps:

1. Add a launch argument -devserver sunrise.local to your osu! shortcut.

2. Open the hosts file located in C:\Windows\System32\drivers\etc\hosts (C:\ is your system drive) with a text editor and add the following line:

   ... (rest of the file)
   
   # Sunrise Web Section
   127.0.0.1 sunrise.local
   127.0.0.1 api.sunrise.local
   # Sunrise osu! Section
   127.0.0.1 osu.sunrise.local
   127.0.0.1 a.sunrise.local
   127.0.0.1 c.sunrise.local
   127.0.0.1 assets.sunrise.local
   127.0.0.1 cho.sunrise.local
   127.0.0.1 c4.sunrise.local
   127.0.0.1 b.sunrise.local
   

[!WARNING] Don't forget to save the file after editing.

3. Generate a self-signed certificate for the domain sunrise.local by running the following commands in the terminal:

   openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes -keyout sunrise.local.key -out sunrise.local.crt -subj "/CN=sunrise.local" -addext "subjectAltName=DNS:sunrise.local,DNS:*.sunrise.local,IP:10.0.0.1"
   

4. Convert the certificate to the PKCS12 format (for ASP.Net) by running the following command in the terminal:

   openssl pkcs12 -export -out sunrise.pfx -inkey sunrise.local.key -in sunrise.local.crt -password pass:password
   

5. Import the certificate to the Trusted Root Certification Authorities store by running the following command in the terminal:

   certutil -addstore -f "ROOT" sunrise.local.crt
   

6. Move the generated sunrise.pfx file to the Sunrise directory.

7. Run the server and navigate to https://api.sunrise.local/docs to check if the server is running.
