ec2-leaser

A tiny tool to allow google user to start EC2 instances from a list of Launch Template already created. It can be used to not provide startInstance IAM right yo your users.

EC2 Leaser

It's also possible to snapshot and restore instances!

Architecture

The backend is managed serverlessly via SST. The frontend is a React application. It's design to be deployed on AWS.

How to run the application locally ?

Run the backend only (you need only that to use a local frontend):

yarn
yarn dev

Start the frontend:

cd packages/web/
yarn dev

no need to provide environment variables, are these are made available to the frontend via SST.

How to deploy the application

Deploy the infrastructure with SST (front and back stack) (it push the frontend to S3 and invalidate cloudfront distribution)

yarn deploy --stage prod --region eu-central-1 # on aws prod account
yarn deploy --stage demo --region us-east-1 # on aws demo account

Cost center data content

To add cost center list so that the frontend can make use of it, add items directly from the AWS GUI: visit DynamoDB section search for {stage}-ec2-leaser-config

See below for an example on how to enter the items in the table.
