Reduce iterations to two

[jonodrew]

I've done my best to make this flexible by passing the number of iterations as an environment variable. That means that, if we want to deploy this code for anyone else, we can create a new Stack object with a different number of iterations

I would also point out that, if users only want two iterations instead of the usual three, they could simply...not use the last set.

Bizarrely, this is still outputting 3 matches for me, even after a clean build of the app.
Must be some kind of error with my local machine. The code I have in the local repo is the same as the remote repo, it's just still churning out 3 matches!

Your build evidently is working correctly though, based on the screenshot.

Before we merge this, I think we should make this an extra screen and a selectable option.
Thoughts?

Let's make sure it's working for you first. You'll need to set an environment variable for this to work. The easiest way to do this is probably through the Dockerfile - I can add something to the readme. The reason I've got the screenshot is because I deployed the whole thing into AWS with the environment variable set to two - that's what 96f1330 does

@johnpeart try with the new commit on this branch, and change the ITERATIONS value in docker-compose.yml

No dice.

I've tried:

1. deleting the docker container and rebuilding using docker-compose up – same result, 3 matches
2. clearing browser cache and then repeating 1 – same result, 3 matches
3. deleting the repo and cloning it again, and repeating 1 and 2 – same result, 3 matches

😕

Bizarre - definitely working for me. You're definitely pulling this branch?

[johnpeart]

Definitely the right branch, so it's clearly something weird with my set up.

Running docker system prune to remove everything and then rebuilding the container doesn't fix the issue but oddly, running docker exec mentor-match-worker-1 env to pull the environment variables picks up ITERATIONS=2.

So it must be the right files; just building the wrong outputs.
