aca-resiliency

Simple lab to discover how resiliency policies works in Azure Container Apps

cd src

$vGen="4.0.0"
$vPro="0.0.4"

docker build . --tag aca-processor:$vPro --file .\OrderProcessor\Dockerfile --no-cache
docker build . --tag aca-generator:$vGen --file .\OrderGenerator\Dockerfile --no-cache

docker run -p 8092:80 --detach aca-processor:$vPro

Publish on docker hub

docker login -u massimocrippa -p surething

docker tag aca-generator:$vGen massimocrippa/aca-generator:$vGen
docker push massimocrippa/aca-generator:$vGen

Deploy Infra, App and resiliency policy

cd infra

sh deploy-lab-on-consumption-v2.sh

Test the resiliency policy

Use the aca-generator to trigger N requests to the aca-processor API

Circuit breaker

• 1 returns 503
• 2 after three 503 a circuit breaker is triggered
• 3 the circuit is reopened after 10 seconds

Retry

• a 429 is returned
• a the call is retried but fails again
• 200 ok is returned with the third try
