Allow "bring your own" Azure resource group and app plan?

[ericis]

• Let devs define existing resource groups and do not destroy them
• Let devs define existing app plans and do not destroy them (will need to verify the plan type is compatible though...)

New support for idempotent cloud resources in some of the projects allows for existing Resource Groups and AppService Plans, but not all projects have been updated yet.

hello-cloud/src/services/nodejs/expressjs/webapi/deploy/azure/install.sh

Lines 56 to 71 in 9bb91c8

	resource_group_exists_output=$(az group show \
	--resource-group "$azure_resource_group" \
	--output json 2>&1 || true)
	if contains "$resource_group_exists_output" "ResourceGroupNotFound"; then
	echo 'Creating Azure Resource Group...'
	az group create \
	--resource-group "$azure_resource_group" \
	--location "$azure_region"
	echo 'Successfully created Azure Resource Group.'
	else
	echo 'The Azure Resource Group already exists.'
	fi

⚠️ However, the code still assumes to destroy the cloud infrastructure. This would need to be updated with a flag that defaulted to "off" to keep existing cloud infrastructure.

hello-cloud/src/services/nodejs/expressjs/webapi/deploy/azure/uninstall.sh

	resource_group_exists_output=$(az group show \
	--resource-group "$azure_resource_group" \
	--output json 2>&1 || true)
	if ! contains "$resource_group_exists_output" "ResourceGroupNotFound"; then
	echo 'Deleting Azure Resource Group, including child resources...'
	az group delete \
	--name "$azure_resource_group" \
	--yes
	echo 'Successfully deleted the Azure Resource Group.'
	else
	echo 'The Azure Resource Group does not exist.'
	fi
