Quick Tests

List buckets:

aws --endpoint-url https://localstack.paulononato.com.br s3 ls

Send a message to the Quantum queue:

aws --endpoint-url https://localstack.paulononato.com.br sqs send-message \
  --queue-url "$(tofu output -raw quantum_queue_url)" \
  --message-body file://../../examples/quantum-message.json

Read the secret:

aws --endpoint-url https://localstack.paulononato.com.br secretsmanager get-secret-value \
  --secret-id "$(tofu output -raw quantum_secret_name)"

RDS Note

RDS is not included in the LocalStack Community edition provisioned on the server. This project avoids RDS and uses only the services available in the current stack.
