 To deploy a Serverless service to AWS you will need to create an IAM user with the required permissions and set credentials. I'm setting credentials using [Bitbucket Pipelines environment variables](https://confluence.atlassian.com/bitbucket/environment-variables-in-bitbucket-pipelines-794502608.html); however setting credentials in Dockerfile is also possible.
