How to use

Requirements:

  • AWS access

  • AWS CLI (brew install awscli)
  • Terraform v0.14.11

Configure AWS

RUN aws configure

Make functions

RUN primer make functions

Example

  ➜  primer make functions
  zip -r functions/transactions.zip transactions.py
  updating: transactions.py (deflated 59%)
  zip -r functions/populate.zip populate.py
  updating: populate.py (deflated 51%)

Make layers

Example

  mkdir -p chalice/python
  pip3 install chalice -t chalice/python
  cd chalice 
  zip -r chalice.zip python

Once done, move the zip to the layers directory.

Run terraform

Go to /terraform/playground and run:

Init
  terraform init

Plan
  terraform plan -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1" 

Apply
  terraform apply -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1" 

Destroy
  terraform destroy -var username="gertjan" -var environment="playground" -var aws_region="eu-west-1"

Test the API:

Populate the table with some data using:

curl -X POST APIGW_URL/populate

List transactions:

curl -X GET APIGW_URL/transactions

Filter transactions by merchant:

curl -X GET APIGW_URL/transactions?merchant=merchant_name

Get a transaction:

curl -X GET APIGW_URL/transactions/<transaction_id>
