This bot is off

At the moment this bot is disabled due to the reason that it is impossible to pay for VPS and domain name. It is impossible to pay from Russia becaue Visa and MasterCard suspended their operations in Russia, which means cross-border transactions with Visa and MasterCard cards are unavailable, including for both purchases in foreign online stores and transactions abroad.

If you interested in the bot to continue to work, please answer in this issue. This way I will be able to understand if this bot is really used by people. If yes, then I will work on workarounds to launch it again.

Requirements

It is expected that all of the above software is available as a global variables: python3, python3 -m pip, python3 -m venv, git, curl, nginx, psql, heroku, ngrok, docker, docker-compose. See this why you should use such syntax: python3 -m <module>.

All subsequent instructions is for Unix-like systems, primarily for Linux. You may need to make some changes on your own if you work on non-Linux operating system.

If you want to host this server somewhere outside of Heroku, then you may need to install additional software. See your host installation guide.

Installation

  1. Clone this repository.
git clone https://github.com/Amaimersion/yandex-disk-telegram-bot.git
cd yandex-disk-telegram-bot
  1. Create virtual environment.
python3 -m venv venv

And activate it:

source ./venv/bin/activate

Run deactivate when you end in order to exit from virtual environment or just close terminal window.

After that step we will use python instead of python3 and pip instead of python3 -m pip. If for some reason you don't want create virtual environment, then:

  • use python3 and python3 -m pip,
  • edit executable paths in .vscode/settings.json,
  • edit names in ./scripts files.

You probably need to upgrade pip, because you may have an old version (9.0.1) instead of new one. Run pip install --upgrade pip.

  1. Install requirements.
./scripts/requirements/install.sh
  1. Set environment variables.
source ./scripts/env/<name>.sh

Where <name> is either production, development or testing. Start with development if you don't know what to use.

These environment variables are required to create right app configuration, which is unique for specific environemts. For example, you can have different DATABASE_URL variable for production and development.

You need these environment variables every time when you implicitly interact with app configuration. For example, DB upgrade and background workers implicitly create app and use it configuration.

If you forgot to set environment variables but they are required to configure the app, you will get following error: Unable to map configuration name and .env.* files.

  1. If you want to use database locally, then make DB upgrade:
flask db upgrade
  1. Run this to see more available actions:
python manage.py --help
  1. Every time when you open this project again, don't forget to activate virtual environment.

That's all you need to set up this project. If you want to set up fully working app, then:

  1. Perform integration with external API's.

  2. See Local usage for development and Deployment for production.

Integration with external API's

Telegram

  1. Register your bot in chat with @BotFather and get API token.

  2. Set a webhook:

./scripts/telegram/set_webhook.sh <TELEGRAM_BOT_TOKEN> <SERVER_URL> <MAX_CONNECTIONS>

Russian users may need a proxy:

./scripts/telegram/set_webhook.sh <TELEGRAM_BOT_TOKEN> <SERVER_URL> <MAX_CONNECTIONS> "--proxy <PROXY>"

For parameter MAX_CONNECTIONS it is recommended to use maxium number of simultaneous connections to the selected database. For example, "Heroku Postgres" extension at "Hobby Dev" plan have connection limit of 20. So, you should use 20 as a value for MAX_CONNECTIONS parameter in order to avoid possible Too many connections error.

From Telegram documentation:

If you'd like to make sure that the Webhook request comes from Telegram, we recommend using a secret path in the URL, e.g. https://www.example.com/<token>. Since nobody else knows your bot‘s token, you can be pretty sure it’s us.

So, instead of /telegram_bot/webhook you can use something like this: /telegram_bot/webhook_fd1k3Bfa01WQl5S. To achieve this set environment variable TELEGRAM_API_WEBHOOK_URL_POSTFIX. In that case it is TELEGRAM_API_WEBHOOK_URL_POSTFIX=_fd1k3Bfa01WQl5S.

Yandex.Disk

  1. Register your app in Yandex. Sometimes it can take a while for Yandex moderators to check your app.

  2. Get your app ID and password at special Yandex page for your app.

  3. At special Yandex page for your app find "Callback URI" setting and add this URI: https://<your site>/telegram_bot/yandex_disk_authorization. It is required if you want to use AUTO_CODE_CLIENT Yandex.OAuth method, which is configured by default.

Local usage

Environment variables

In a root directory create .env.development file and fill it based on .env.example file.

Server

What the app uses

This WSGI App uses gunicorn as WSGI HTTP Server and nginx as HTTP Reverse Proxy Server. For development purposes only flask built-in WSGI HTTP Server is used.

flask uses http://localhost:8000, gunicorn uses unix:/tmp/nginx-gunicorn.socket or http://0.0.0.0:8080, nginx uses http://localhost:80. Make sure these addresses is free for usage, or change specific server configuration.

nginx will not start until gunicorn creates /tmp/gunicorn-ready file. Make sure you have access rights to create this file.

By default gunicorn listens on unix socket instead of ip socket. You can enable ip socket by setting GUNICORN_USE_IP_SOCKET environment variable.

Open terminal and move in project root. Run ./scripts/wsgi/<environment>.sh <server> where <environment> is either prodction, development or testing, and <server> is either flask, gunicorn or nginx. Example: ./scripts/wsgi/production.sh gunicorn.

Usually you will want to run both gunicorn and nginx. To do so run scripts in separate terminals (recommend way). After that visit nginx address.

Run ./scripts/server/stop_nginx.sh in order to stop nginx.

nginx uses simple configuration from ./src/configs/nginx.conf. You can ignore this and use any configuration for nginx that is appropriate to you. However, it is recommended to use exact configurations as in app for both flask and gunicorn. If you think these configurations is not good, then make PR instead.

What you should use

For active development it will be better to use only flask WSGI HTTP Server.

source ./scripts/wsgi/development.sh flask

That command will automatically set environment variables and run flask WSGI server. And your app will be fully ready for incoming requests.

If you want to test more stable and reliable configuration which will be used in production, then run these commands in separate terminal window.

source ./scripts/wsgi/development.sh gunicorn
source ./scripts/server/stop_nginx.sh
source ./scripts/wsgi/development.sh nginx

Database

What the app uses

In both development and testing environments SQLite is used. For production PostgreSQL is recommended, but you can use any of supported databases. App already configured for both SQLite and PostgreSQL, for another database you may have to install additional Python packages.

By default both development and testing databases will be located at src/temp.sqlite. If you want to use different name for DB, then specify value for DATABASE_URL in .env.development and .env.testing files.

Redis database is supported and expected, but not required. However, it is highly recommended to enable it, because many useful features of the app depends on Redis functionality and they will be disabled in case if Redis is not configured using REDIS_URL.

What you should use

Usually it will be better to manually specify DB name in .env.development and specify REDIS_URL. Try to always use Redis, including development environment. If you decide not to enable Redis, it is fine and you still can use the app with basic functionality which don't depends on Redis.

Background tasks

What the app uses

RQ is used as a task queue. Redis is required.

Examples of jobs that will be enqueued: monitoring of uploading status and uploading of files.

The app is not ready to support other task queues. You may need to make changes on your own if you decide to use another task queue.

How to use that

It is highly recommended that you run at least one worker.

  1. Make sure REDIS_URL is specified.
  2. Open separate terminal window.
  3. Activate venv and set environment variables.
  4. Run: python manage.py run-worker

These steps will run one worker instance. Count of workers depends on your expected server load. For development environment recommend count is 2.

Note that RQ will not automatically reload your running workers when source code of any job function's changes. So, you should restart workers manually.

Expose local server

What the app uses

ngrok is used to expose local server. It is free and suitable for development server.

What you should use

You can use whatever you want. But if you decide to use ngrok, the app provides fews utils to make it easier.

Before:

  • requests will be routed to /telegram_bot/webhook, so, make sure you didn't change this route,
  • you also should have jq on your system.

Then:

  1. Run flask server:
source ./scripts/wsgi/development.sh flask
  1. In separate terminal window run ngrok:
source ./scripts/ngrok/run.sh
  1. In separate terminal window set a webhook:
source ./scripts/ngrok/set_webhook.sh <TELEGRAM_API_BOT_TOKEN>

Where <TELEGRAM_API_BOT_TOKEN> is your Telegram bot API token for specific environment (you can have different bots for different environments).

Translations

What the app uses

Translations are built on top of Babel, which provides support for GNU gettext.

How to use that

If you want to enable translations, then before server start you should compile existing raw translations:

python manage.py compile-translations

If you want to update existing translations to match actual app state, then run this, edit changed lines in translations files, and recompile updated translations:

python manage.py update-translations

If you want to add translations for new language, then run this, fill translations file, and recompile updated translations:

python manage.py init-translations <SMALL LETTERS LANGUAGE CODE>

Deployment

Regardless of any platform you choose for hosting, it is recommended to manually configure number of workers, number of workers connections and number of threads for both gunicorn and nginx.

Before

It is recommended to run linters with source ./scripts/linters/all.sh before deployment and resolve all errors and warnings.

Heroku

It is a way to host this app for free. And that will be more than enough until you have hundreds of active users.

First time

  1. If you don't have Heroku installed, then it is a time to do that.

  2. If you don't have Heroku remote, then add it:

  • for existing app:
git remote add heroku <URL>
  • for new app:
heroku create
  1. We need both python and nginx build packs. Python build pack should be added automatically, but we will do it manually. For nginx build pack you can use whatever you want: official one, my own one or create your own one. In case of not using my own nginx build pack don't forget about compatibility (config paths, environment variables names, etc.).
heroku buildpacks:set heroku/python
heroku buildpacks:add https://github.com/Amaimersion/heroku-buildpack-nginx-for-yandex-disk-telegram-bot.git
  1. We need Heroku PostgreSQL addon in order to use that database.
heroku addons:create heroku-postgresql:hobby-dev

Later you can view the DB content by using heroku pg:psql.

  1. We need Heroku Redis addon in order to use that database.
heroku addons:create heroku-redis:hobby-dev
  1. Set required environment variables:
heroku config:set SERVER_NAME=<your host without scheme>

You may also want to set recommended environment variables:

heroku config:set NGINX_WORKERS=<value>
heroku config:set NGINX_WORKER_CONNECTIONS=<value>
heroku config:set GUNICORN_WORKERS=<value>
heroku config:set GUNICORN_WORKER_CONNECTIONS=<value>
  1. Switch to a new branch that is special for Heroku (don't ever push it!):
git checkout -b heroku

If that branch already created, then just type:

git checkout heroku

  1. Make sure .env.production file is created and filled. Remove it from .gitignore. Don't forget: don't ever push it anywhere but Heroku.

  2. Add changes for pushing to Heroku:

  • if you edited files on heroku branch:
git add
git commit -m <message>
  • if you want push changes from another branch:
git merge <another branch> -m <message>
  1. Upload files to Heroku:
git push heroku heroku:master
  1. Set number of workers for background tasks. On free plan you cannot use more than 1 worker.
heroku scale worker=1

What's next

You should do steps № 7, 9 and 10 every time when you want to push changes.

VPS

Use docker or see installation.

Docker

This project provides Docker images along with configured docker-compose file. Usage of docker-compose is recommended way to deploy or run this application.

Deployment

  1. Clone this repository.

  2. In the root directory create .env.production file and fill it based on .env.example file.

  3. Run docker-compose:

docker-compose up

You don't need to configure any process control system in order to run docker-compose in background on every system start. It is already done by Docker daemon.

  1. By default docker-compose will listen for connections on http://127.0.0.1:8080. It is recommended to set up some reverse proxy server (along with TLS, logs and so on) in the front of docker-compose and redirect connections on that address. Or you can override docker-compose configuration to listen for connections immediately on http://127.0.0.1:80.

Development

You can run docker-compose in development workflow.

  1. Clone this repository.

  2. In the root directory create .env.development file and fill it based on .env.example file.

  3. Run docker-compose:

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

Keep in mind that data that already stored in ./var folder will be used. If there is no data, then new one will be created. It is means that data is common for both development and production. If you don't want this behavior, then consider to create several clones of the project or override docker-compose config.

  1. Run ngrok to handle incoming connections:
source ./scripts/ngrok/run.sh 8080
  1. Set a webhook:
source ./scripts/ngrok/set_webhook.sh <TELEGRAM_API_BOT_TOKEN>
  1. After that you can edit code in ./src folder. Hot reloading is enabled.

Data

By default docker-compose will store data of some services locally on a host machine. It is persistent data that stores state of your app, so, don't delete it.

PostgreSQL will store its data in ./var/lib/postgresql/data folder. Redis will store its data in ./var/lib/redis.

Most probably you shouldn't interact with that data directly. Instead, consider to make backups.

Backups

On some point you may want to backup your PostgreSQL data. Don't copy/paste ./var/lib/postgresql/data folder. Instead, perform following commands:

  • to backup data, run on a host machine:
docker exec -t yd-tg-bot-postgres pg_dump -U <POSTGRES_USER> -d <POSTGRES_DB> > dump.sql
  • to restore data, run on a host machine:
cat dump.sql | docker exec -i yd-tg-bot-postgres psql -U <POSTGRES_USER> -d <POSTGRES_DB>

dump.sql is entire backup of your DB. Keep it somewhere safe, outside of host machine.

Feel free to modify above commands. It is just an example of how to do it. You can even use your own way to backup/restore your data.

Before restoring <POSTGRES_DB> database should be clean, but created. By default the app upgrades database at startup, which means that database will have some data. You will need to manually drop and create database:

docker exec -it yd-tg-bot-postgres psql -U <POSTGRES_USER> -d postgres
DROP DATABASE <POSTGRES_DB>;
CREATE DATABASE <POSTGRES_DB>;

Keep in mind that database have encrypted data in some tables. It is means that you should use exact a same FLASK_SECRET_KEY environment variable that was used at the moment of database backup. You will be not able to fully interact with database if you will use different FLASK_SECRET_KEY. So, usually you will also want to backup your .env.production file in order to keep your secrets.

Logs

Use docker-compose logs. If you want to write logs in file, do not change docker-compose config. Instead, redirect output of command to file.

Resources

This project have gunicorn and rq, which have workers that creating fork of parent process. It is means extensive usage of machine resources, particularly RAM.

Consider your host machine resources when you configuring GUNICORN_WORKERS, RQ_WORKERS and other settings that may affect as usage of machine resources. Use these commands to monitor usage of resources:

docker stats
docker-compose top

Version naming

This project uses following structure for version naming: <MAJOR CHANGES>.<BIG CHANGES>.<SMALL CHANGES>.

  • "Major changes" usually means really cardinal changes. Such changes may require from developers to set up application again, inspect new technical stack and app architecture. It is certainly incompatible with the earlier application code.
  • "Big changes" usually means new features, big changes or long-awaited bug fixes. Such changes may require big time to test and complete. Main development workflow goes here.
  • "Small changes" usually means some small changes or fast bug fixes. Most likely every version will contain small amount of changes.

Contribution

Feel free to use issues. Pull requests are also always welcome!

Translations

If you want to translate this app, then you will need to perform following steps:

  1. Make sure you installed the project.

  2. Run:

python manage.py init-translations <LANGUAGE CODE>
  1. Fill new translation file that is located at translations/<LANGUAGE CODE>/LC_MESSAGES/messages.po.

Next step is not mandatory for you and can be performed by project owner. You can just create a PR with result from step up to № 3. However, next changes are required in order to enable new translation.

  1. Make code changes according to these commits: d6bc3fe, 9a34008. Actual code may be slightly different.
