SteamGifts bot to enter only for whitelisted games

I wish I would win all my followed and wishlisted games ;) I don't want win all the games in SG and this bot will apply only for whilelisted games.

This is my first project in GO (and there no some goish features like channels and coroutines - just syntax)

This is python implementation which inspired me to do this https://github.com/theWaR13/SteamGiveawayManager

SGBot as a cloud function

If you have some cloud functions service (AWS Lambda, Yandex.Cloud, etc) you could try to install this bot as cloud function. At this point you can install it on Yandex.Cloud (as I did). Frankly, there is 3 cloud functions: bot which checks, email sender and script with db seeding.

Create DB for games, cookies and digest

1. Create YandexDB (YDB) serverless database
2. Copy DB 'location'

Create bot init function

1. Run yandex.botinit-func.deploy.sh - it prepares all mandatory files
2. Create function from zip archive, choose Go/1.17, set 128M, 60sec timeout, set bot-init-func.RunInitBotDB as entry point
3. Create service account with editor privelegies for YDB
4. Set YDB_DATABASE (this is location from YDB) environment variables
5. Finish function creation
6. Run function once (test). It has to create 3 tables into YDB: games (id:uint64, name:string), cookies (name:string, domain:string, path:string, value:string) and digest (message:UTF8)

Create bot function

1. Run yandex.sgbot-func.deploy.sh - it prepares all mandatory files
2. Create function from zip archive, choose Go/1.17, set 128M, 60sec timeout, set bot-func.RunSGBOTFunc as entry point
3. Create service account with editor privelegies for YDB
4. Set STEAM_PROFILE, STEAM_API_KEY and YDB_DATABASE (this is location from YDB) environment variables
5. Finish function creation
6. Create trigger for schedule function invokation (hourly - but you can check as you wish)
7. Create service account (or add to existing serverless.invoker role)
8. It has to work!

Create digest function

1. Run yandex.digest-bot.deploy.sh - it prepares all mandatory files
2. Create function from zip archive, choose Go/1.17, set 128M, 5sec timeout, set digest-func.SendDigest as entry point
3. Create service account with editor privelegies for YDB (or use existing)
4. Set MAILER_SMTP, MAILER_PORT, MAILER_AUTH_NAME, MAILER_AUTH_PWD, MAILER_SUBJECT, MAILER_RECIPIENT environment variables for mailer creation and YDB_DATABASE for DB connection
5. Finish function creation
6. Create trigger for schedule function invokation (daily - but you can send as you wish)
7. Create (select) service account with serverless.invoker role
8. It has to work!

gogbot

Check GOG.com for giveaways (only for cloud functions)

Prerquisites

Run bot-init (from sgbot TODO: make this function and digest like shared function) to create cookie database. Create digest function too for receive emails.

Deploy and run gogbot func

1. Run yandex.gogbot-func.deploy.sh - it prepares all mandatory files
2. Create function from zip archive, choose Go/1.17+, set 128M, 60sec timeout, set bot-func.RunGOGBOTFunc as an entry point
3. Create or use existed (created for sgbot for example) service account with editor privelegies for YDB
4. Set YDB_DATABASE (this is location from YDB) environment variables
5. Finish function creation
6. Create trigger for schedule function invokation (daily - but you can check as often as you wish)
7. Create service account (or add to existing serverless.invoker role)
8. Add necessary cookie gog-al to database with domain like gog.com
9. It has to work!

Bot writes something to log in 2 cases: first, if you won something, and second - if cookies are expires or invalid (401 - unauthorized). In other cases bot writes to log return code (to analyze if somethig will change).
