Docker container

To check already running containers on the system use command:

If there is previously ran container cuteiner, remove it:

$ docker rm -f cuteiner

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

$ docker run -v $(pwd)/TOKENS:/go/src/app/TOKENS -d --name=cuteiner cuteimage --loglevel=info

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.
