Deployment

AWS Infrastructure

0. Login or create a new AWS Account.
   • The AWS free tier account will cover a good number of requests for ceremonies but there could be some costs based on your ceremony circuits size.
1. Create an access key for a user with Admin privileges (NOT ROOT USER)
2. Setup the awscli (docs) and add the keys for this user.
3. Install terraform (docs)
4. Decide on an AWS region (by default this is us-east-1) - if you want to change you will need to do the following:
   1. update aws/lambda/index.mjs (exact line) to the new region
   2. update main.tf (exact line) to the new region
5. zip the Lambda folder:
   1. cd lambda
   2. zip -r ../lambda.zip .
6. Run terraform:
   1. terraform init
   2. terraform plan
   3. terraform apply
   4. terraform output secret_key
      • To print the secret access key for the IAM user
   5. Store the other values (sns_topic_arn etc.)
      • These will be needed for the .env file configuration

The IAM user created with the steps above can be used for all p0tion's features.
