about

This is a simple frontend that talks to a backend jar. I use it to investigate various deployment ways

components

frontend

a simple app that uses the backed and displays the result.

backend

Cors enabled for everywhere (for now)

curl -X POST localhost:8080/echo -d '{"request":"world"}' -H "Content-Type: application/json" --silent |jq
{
  "response": "hello world"
}

codebuild (aws)

local

see https://aws.amazon.com/blogs/devops/announcing-local-build-support-for-aws-codebuild/

build local

requirements

• maven
• java 11
• node
• terraform
• gnu make

instructions

(cd src/backend && ./mvnw clean package )
(cd src/frontend && npm install && npm run build)

when you run the server locally use something like:

curl -d '{"request":"hello"}' http://localhost:5000/echo -H 'Content-Type:application/json'

to test

deployment

local

cd src/backend && ./mvnw clean spring-boot:run
#in another window
cd src/frontend && node start

terraform

see readme for initialization instructions

api gateway

( cd deploy/api-gateway-s3-eb
 && terraform apply)

(cd src/backend && make ebdeploy)

(cd src/frontend && make deploy)
#this outputs the url
#the backend deploy might take some time to finish
#use curl to check when it is back up
