error with this application where their todo list items fail to save upon refreshing

I am extremely discouraged by my grasp of docker for this job. I'm completely new to this realm of work, but I'm willing to do everything it takes to give it my best shot. Learning docker has been very overwhelming for me, because I don't have any prior experience or knowledge. I'm asking for help on how I should narrow my focus to perhaps pass the technical portion of the interview. This is what I am tasked with: Open this zip file on your machine locally. It contains a small docker-compose todo application. The customer has reported an error with this application where their todo list items fail to save upon refreshing. Follow the [login to view URL] document to set up the application. First, try to replicate the customer’s complaint Document the steps you took to replicate the issue. Attempt to find the root cause of the issue. The solution should not require any code changes. At the end of 90 minutes, you will finish at one of two points; both are good ending spots! You are confident you found the answer You didn’t find the answer, though you made some great progress toward that Depending on where you ended, provide us one of the following: Your draft answer to the customer (write it as if you are writing a real customer) AND a note to your internal teammates on how you got to the answer (write this as if you are writing your teammates to show them your thought process) AND how long the Docker install took (if relevant) An initial response to the customer (write it as if you are writing a real customer) AND a note requesting help from your teammates (write this as if you were writing your teammates to show them your thought process), sharing what you need, what you have done so far, your thought process, and all relevant technical details AND how long the Docker install took (if relevant) Could you please help show me what I need to learn to complete the given task?
