Installation Example with Ubuntu, Docker, and Nginx Proxy Manager

[ApuRed]

This example is using a VPS Ubuntu 22.xx with dedicated IP and a subdomain pointing to the IP

It is recommended not to use root as the main user, for this we create a user, give it administrator permissions
sudo adduser sms
sudo usermod -aG sudo sms
sudo su - sms

we can continue with the tutorial

1.- Have a Virtual Machine with docker and docker compose
To install you can use these tutorials:
https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-22-04
https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-compose-on-ubuntu-22-04

2.- Create a docker-compose.yaml file (SMS - MySQL - nginx) - you can use this example and adapt it to your liking
docker-compose.yaml.txt

3.- create a config.yml file (you can use the administrator guide at https://sms.capcom.me/getting-started/private-server/)
config.yml.txt

4.- Upload these files to the server (create a preferred folder)

5.- enter the server via putty using cd /[dir-create] and execute the command "docker compose up -d"

6.- When finished, enter server-ip:81 via web to enter the nginx administrator and use the data:
Email: [email protected]
Password: changeme

7.- Change service access and configure a new proxy host

8.- If everything went well you will be able to see that the service is active.

9.- do not forget to configure the URL and Token in the APP

10.- We tested our service with postman.

11.- and the test sms will arrive where we indicate

I hope it helps you, if you have questions you can read the documentation or comment to add more details.

PS: All rights and thanks to the creator of this service, it is useful for my business.
PS2: The manual is still being modified, your contributions will help achieve a 100% effective and safe manual.

Hello!

Thank you for providing these detailed instructions. Your contribution will undoubtedly benefit others in the community.

I'd like to share a couple of notes regarding your docker-compose.yml setup. I suggest avoiding directly opening ports from backend and db to mitigate potential security risks.

Here are some additional recommendations:

• You can increase the tasks.hashing.interval_seconds value in config.yml to minimize the load on the database. I think, frequent hashing isn't necessary when the server is hosted in private mode.
• It appears you initiated docker compose with root privileges. It's generally best practice to create a separate user with membership in the docker group and run docker compose as that user.
• In step 7, concerning the proxy host configuration, using the hostname backend to refer to the backend container might be more convenient. Since Nginx and the backend are running on the same Docker network, this approach simplifies the configuration. If you remove the port mapping for the backend container as I recommended earlier, the setup from your screenshot won't work.

Also, I want to thank you for pointing out jc21/nginx-proxy-manager. It's an interesting project that was new to me as well.

I'll be shifting this question over to the discussion section for easier access and further engagement.

Thanks again for your valuable input!

Thank you for the comprehensive guide. It is well-constructed and detailed. However, I noticed there is no information on how to obtain the necessary credentials. Could you please provide guidance on where to acquire these credentials? I attempted to use the Authorization generated by the app when connecting to the server, but it did not work.

I tried executing the POST request to https://my-domain/api/3rdparty/v1/message and received the following message:

{
    "message": "Unauthorized"
}

Thank you very much.

@yahya567, hello!

The credentials are displayed on the Home screen of the app. However, if you are using a Private Server, please ensure that you set the full URL (including path /api/mobile/v1) and token in the app settings. Don't forget to restart the app by using the button on the Home screen.

Worked. Thank you.

Before i begin i would like to thank you @ApuRed for the detailed guides and @capcom6 for making the project open source 😊

Describe the Bug
When attempting to access the SMS Gateway backend API through xxx.xxx.xxx.xxx:3000/api, instead of the expected Swagger UI, a white screen is displayed. The console shows multiple 404 errors, indicating that the resources (such as CSS and JS files for Swagger UI) are not being found.

To Reproduce

1. Deploy SMS Gateway containers using Docker Compose on a Hetzner server running Ubuntu 2024.
2. Ensure all containers are running as verified in Portainer.
3. Attempt to access the API endpoint via http://xxx.xxx.xxx.xxx:3000/api.
4. Observe that a white screen is displayed, and the console logs 404 errors.

Expected vs Actual Behavior

1. Expected: Swagger UI should load correctly when accessing the API endpoint, allowing interaction with the API documentation.
2. Actual: The Swagger UI fails to load, resulting in a white screen and multiple 404 errors in the console.
3. Screenshots

The provided screenshots illustrate the running containers and the console errors encountered when attempting to load the Swagger UI.

Environment

• App Version: Likely the latest version as pulled by Docker.
• Mode: Cloud (on Hetzner server)
• Operation: Setting up and testing SMS Gateway backend
• Network Type: Static IP provided by Hetzner

Additional Context
It appears that the backend API is not correctly serving the Swagger UI resources, leading to the 404 errors. This could be due to incorrect file paths, misconfigured environment variables, or issues in the Docker configuration.

Did i forgot something to configure? i just follow the guide and the documentation on setting up the private server.

Hello!

It's possible that the issue is due to a "trailing slash problem". Try adding a slash at the end of the path, like this: xxx.xxx.xxx.xxx:3000/api/.

I will try to fix it in the next version.

[KleKlai]

hi @capcom6 thank you for your reply.

I can now access swaggerUI

using the solution you provided about trailing slash problem. Thank you 😁

[capcom6]

Thanks for your feedback!

Will be fixed in next server release: android-sms-gateway/server#84
