do
    echo "$region"

Create artifact.zip

yarn build
rm artifact.zip
zip --quiet -r artifact.zip lib

Deploy

First, enable all the AWS regions here: https://console.aws.amazon.com/billing/home?#/account

cd infra

Create a local.auto.tfvars file inside the infra folder like this:

access_key = "xxx"
secret_key = "yyy"

And finally deploy:

export GODEBUG=asyncpreemptoff=1;
terraform init
terraform apply

Dispatch targets

Modify the target URL and number of requests in the ops-scripts/sqs-dispatch.ts file. Then:

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy
export AWS_ACC_ID=111

ts-node ops-scripts/sqs-dispatch.ts

Print stats for all regions

Shows how many requests are still in flight.

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy
export AWS_ACC_ID=111

ts-node ops-scripts/sqs-stats.ts

Purge all queues

Emergency script to purge all SQS queues to stop Lambdas running.

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=yyy
export AWS_ACC_ID=111

ts-node ops-scripts/sqs-purge.ts

Redeploy Lambda code changes

1. Repeat steps in Create artifact.zip
2. Repeat steps in Deploy
