Create and start a container in background (-d) from image cuteimage. Bind mount volume TOKENS, assign the name cuteiner to the container. To change log level use parameter app --loglevel

Project Description

Traverse all pull requests in Docker repository on Github and look for links in pull request body. The pull requests can be retrieved page by page.
After the link is found try to get an image from URL.
Check if the image is the screenshot. Don't post the screenshot and skip it.
If the image is a picture, check the size of it because there is a twitter limit for media upload. Resize an image if needed.
Encode image to string.
Before posting new tweet we need to check the number of last posted pull request. Check most recent twitter timeline and find the largest number of posted pull request.
If there is no link in pull request just skip it. Otherwise, post it to twitter.
Update twitter every 60 seconds for new cuties.
There is a notification about screenshots and errors. There will be the direct message to twitter about it.
