How to set up this challenge

This challenge requires a bit of set up from terraform and it probs could be done better but here it is.

Set up Project and gcloud

Sign into your Google Cloud Platform account and create a new project with what ever name
Once it has been created note the project id
In gcloud make sure you are logged in with the same account with gcloud auth login

Set up infra with terraform

Download the right terraform binary to the challenge/terraform folder and run ./terraform init
Update challenge/terraform/terraform.tfvars with the variables, the first is your project ID from above and then a globally unique bucket name ( no one in the world can have the same bucket name)
Run ./terraform plan check the output make sure it looks all good
Run ./terraform apply to apply the infrastructuyre set up

Set up Cloud Function and App Engine

I know you can do this with terraform but I couldn't be bothered to find a way to deploy src code to a bucket

Navigate to the challenge/app-src directory and run gcloud app deploy --project <Your Project ID>
Navigate to the challenge/cf-src directory and run gcloud functions deploy professional-signer --region australia-southeast1 --trigger-http --runtime nodejs12 --entry-point signURL --service-account tracy-worker@<your_project_id>.iam.gserviceaccount.com and make sure you say N to any unauthenticated invocations

Create Key and get App Engine URL for chal

To get the IAM key for svc account cory use the command gcloud iam service-accounts keys create cory.json --iam-account cory-worthington@<your_project_ID_here>.iam.gserviceaccount.com provide this to the competitors
Run gcloud app describe --project <your_project_idhere> and get the default_hostname this is the URL to the app engine instance, provide this also to the competitors.

DONE!
