Telegram Settings

Send the commands from filenames in ``telegram_settings`` dir to `@BotFather <https://t.me/BotFather>`__, choose your bot and copy corresponding values in order to use the bot conveniently. Also disable privacy mode if you want to.


Running Locally
~~~~~~~~~~~~~~~

Using `Heroku Local <https://devcenter.heroku.com/articles/heroku-local#run-your-app-locally-using-the-heroku-local-command-line-tool>`__ (preferred)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You will need `Heroku CLI <https://cli.heroku.com/>`__ installed.

::

# For PyPI installs: first download Procfile:
curl -O https://raw.githubusercontent.com/gpchelkin/scdlbot/master/Procfile

# For long polling:
heroku local worker
# For webhooks (you will also need to set up some NGINX with SSL):
heroku local web

Using just Python
^^^^^^^^^^^^^^^^^

::

# For PyPI or Git source system-wide installs:
export $(cat .env | xargs)
scdlbot
# or just:
env $(cat .env | xargs) scdlbot

# For not-installed Git source repository directory:
export $(cat .env | xargs)
python -m scdlbot
# or just:
env $(cat .env | xargs) python -m scdlbot


Deploying to `Heroku <https://heroku.com/>`__
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

|Deploy|

Register on Heroku, press the button above and configure variables for deploying.
When app is deployed you **must** set only one dyno working on
"Resources" tab in your app settings depending on `which way of getting
updates <https://core.telegram.org/bots/api#getting-updates>`__ you have
chosen and set in config variables: ``worker`` for polling or ``web``
for webhook.

Manually
^^^^^^^^

You can do the same as the button above but using `Heroku
CLI <https://cli.heroku.com/>`__, not much of a fun. Assuming you are in
``scdbot`` repository directory:

::

heroku login
# Create app with Python3 buildpack and set it for upcoming builds:
heroku create --buildpack heroku/python
heroku buildpacks:set heroku/python
# Add FFmpeg buildpack needed for youtube-dl:
heroku buildpacks:add --index 1 https://github.com/laddhadhiraj/heroku-buildpack-ffmpeg.git --app scdlbot
# Deploy app to Heroku:
git push heroku master
# Set config vars automatically from your .env file
heroku plugins:install heroku-config
heroku config:push
# Or set them one by one:
heroku config:set TG_BOT_TOKEN="<TG_BOT_TOKEN>" STORE_CHAT_ID="<STORE_CHAT_ID>" ...

If you use webhook, start web dyno and stop worker dyno:

::

heroku ps:scale web=1 worker=0
heroku ps:stop worker

If you use polling, start worker dyno and stop web dyno:

::

heroku ps:scale worker=1 web=0
heroku ps:stop web

Some useful commands:

::

# Attach to logs:
heroku logs -t
# Test run ffprobe
heroku run "ffprobe -version"

Deploying to `Dokku <https://github.com/dokku/dokku>`__
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Use Dokku (your own Heroku) installed on your own server. App is tested and fully
ready for deployment with polling (no webhook yet).
https://github.com/python-telegram-bot/python-telegram-bot/wiki/Webhooks#creating-a-self-signed-certificate-using-openssl

::

export DOKKU=<your_dokku_server>
scp .env $DOKKU:~
ssh $DOKKU
export DOKKU=<your_dokku_server>
dokku apps:create scdlbot
dokku certs:generate scdlbot scdlbot.$DOKKU
dokku config:set scdlbot $(cat .env | xargs)
logout
git remote add dokku dokku@$DOKKU:scdlbot
git push dokku master
ssh $DOKKU
dokku ps:scale scdlbot worker=1 web=0
dokku ps:restart scdlbot
