Redis Sample App

The redis sample app shows how to use the klotho::persist annotation on a node.js redis client to store data.

Prerequisites

This guide assumes:

• pulumi is configured with the proper AWS credentials

Run the app locally

To install redis locally follow the instructions on the official redis getting started page

To set up our local redis cluster, we have defined 4 redis node configurations in sub directories of local-redis-cluster.

Within each sub-directory 8001, 8002, 8003 run

redis-server ./redis.conf

Once all redis nodes are running

redis-cli --cluster create 127.0.0.1:8001 127.0.0.1:8002 127.0.0.1:8003

Once the redis cluster is up and running

npm i 
npx ts-node index.ts

Hit your endpoints

curl -X POST http://localhost:3000/user -d '{"firstName": "john", "lastName": "doe"}' -H "Content-Type: application/json"
# > success%

curl http://localhost:3000/user/john
# > doe%

Compile and Deploy with Klotho

run the terminal commands:

# Compile the app
npx tsc && klotho . --app ts-redis -p aws

# Go into the compiled directory
cd compiled

# If you didn't set the aws region as indicated in the compiler output, do that now
pulumi config set aws:region YOUR_REGION -s ts-redis

# npm install
npm install

# Deploy
pulumi up -s ts-redis

# Outputs: {
#   apiUrl: 'https://<...>.execute-api.<YOUR_REGION>.amazonaws.com/stage/'
# }

Calling your service

# Add a user 
curl -X POST  https://<...>.execute-api.us-east-1.amazonaws.com/stage/user -d '{"firstName": "john", "lastName": "doe"}' -H "Content-Type: application/json"
# > success

# Get a users last name
curl https://<...>.execute-api.us-east-1.amazonaws.com/stage/user/john
# > doe

Clean Up

# Tear down when done
pulumi destroy -s ts-redis
