AKS to Azure SQL

[solomwn]

hi team ,
i create an AKS , here is the steps i take [ Azure CLI ] :
| resource group : az group create --name aks-rg --location westeurope
| vnet : az network vnet create -g aks-rg --name aks-vnet --address-prefixes 10.0.0.0/8 --subnet-name aks-subnet --subnet-prefixes 10.240.0.0/16
| AKS : az aks create /
--resource-group aks-rg
--name aks-cluster --network-plugin azure
--network-policy calico
--vnet-subnet-id /subscriptions/****/resourceGroups/aks-rg/provider/Microsoft.Network/virtualNetworks/aks-vnet/subnet
--load-balancer-sku standard
--node-resource-group resourcegroup
--enable-private-cluster
--docker-bridge-address 172.17.0.1/16
--service-cidr 10.0.0.0/16
--dns-service-ip 10.0.0.10
--enable-cluster-autoscaler
--node-count 1
--max-count 5
--generate-ssh-keys

later i create an ACR and attach it to AKS
| az acr create -g aks-rg --name iweacr --sku Basic
| az aks update -g aks-rg --name aks-cluster --attach-acr iweacr

after that i create an Azure SQL on other resource group
| resource group : az group create --name sql-rg --location westeurope
| SQL Server : az sql server create --name isolserver --g sql-rg --location westeurope --admin-user solomon --admin-password ****
| SQL DB : az sql db create -g sql-rg --server isolserver --name isoldb --edition GeneralPurpose --family Gen5 --capacity 2

now the tricky part at least for me is :
i try to find an image API only to connect to SQL and get just a simple hello and a YAML file to see the arguments on that file to get an idea how PODs connected and get information from Azure SQL through AKS
i test the "Azure front" from Microsoft which is easy to understand that but i want to learn how AKS connects an API to Azure SQL

any help will appreciate

thanks in advanced
