Azure Container apps minimal example

Requiremed tools

az cli
terraform
docker

Steps to reproduce

cd terraform
make sure you are signed in: az login
Run terraform init and terraform apply. You can also create the infrastructure manually. Double check the container apps configuration with the terraform module

build & push the service containers (pwsh script)

$registryName = (terraform output -raw registry_name)

cd ..

az acr login --name "$registryName"

docker build `
    -f ./src/Hello.ServiceA/Dockerfile `
    --build-arg HELLO_ENV `
    -t "$registryName.azurecr.io/testcapp/hello-servicea:0.0.1" `
    ./src/Hello.ServiceA

docker push "$registryName.azurecr.io/testcapp/hello-servicea:0.0.1"

docker build `
    -f ./src/Hello.ServiceB/Dockerfile `
    --build-arg HELLO_ENV `
    -t "$registryName.azurecr.io/testcapp/hello-serviceb:0.0.1" `
    ./src/Hello.ServiceB

docker push "$registryName.azurecr.io/testcapp/hello-serviceb:0.0.1"

Go to the azure portal and deploy the two containers to the two container apps provisioned by terraform.

To run the test just copy the Revision URL to your browse rand open it.

This triggers a handler in service A which then call service B via a grpc call

Check the container app logs

Service A: throws an exception after ~15 sec
