ORION

Serverless image scaling service built with AWS Lambda and API Gateway.

Building the Docker images

A Dockerfile is provided to build a container with the required dependencies.

make container

Set up AWS-CLI

Set up AWS credentials in the container using make and a credentials.csv file containing credentials of an IAM user capable of deploying.

Run make setupAWS after mounting the .csv inside the container in /go

or manually setup credentials yourself using aws configure inside the container

or simply setup environment variables

$ export AWS_ACCESS_KEY_ID=AKIAIOSFODNN7EXAMPLE
$ export AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
$ export AWS_DEFAULT_REGION=us-west-2

Running the container

Run the container with the required directories mounted using the following command

make runcontainer

Building & Packaging

The lambda function must be package into a zip file so it can be deployed by Terraform make zip will build an orion executable and a lambda.zip

Deploying & Destroying

make deploy will automatically build lambda.zip and use Terraform to create the AWS architecture

make destroy conversly destroys the AWS deployment

Run Tests

Run a simple test to check the API Gateway endpoint to ensure that the lambda is working as intended make test

FUTURE

• Require authentication to access lambda
• More features: filters, convertion, video scaling...
• Seamless upgrades and rollbacks by versioning resources with prefixes
