3. What's the flag?

   We log into the deployer container by using:

   cmd

   Copy

   docker exec -it deployer bash
   

   

   Now we can look for our flag. There seems to something hidden in the root folder.

   

   If we run the script found in the root folder we can restore the site.

4. Bonus Question: There is a secret code contained within the news site running on port 5002; this code also happens to be the password for the deployer user! They should definitely change their password. Can you find it?

   On the webpage served on port 5002, we can see a news article. There is some indication here to a multiple parts password hidden in the text.
