Issue with configuring Umbraco from Azure App Configuration | Umbraco | Page 1

Good morning, I am having a very strange issue with Umbraco. we have recently made a push to move our configuration out of app settings and into azure app configuration and key vault for secrets. I have set up a dev environment that has the usual local dev settings that everyone in my team can use. the connection string for Umbraco db is now stored there. when the conn string is in the old appsettings it works fine but when it's only from the azure provider it asks me to install Umbraco db.

usual conn string for local development
Server=.;Database=DbName;User Id=sa;Password=PasswordHere;MultipleActiveResultSets=true;TrustServerCertificate=True

debugging I can see the config provider fine. I can see it being used in the AddUmbraco() extension when I debug it (Downloaded the source code and pointed to it instead of the nuget to get the symbols etc). However when it goes into the AddBackOffice() extension it seems to be pulling in a completely different IConfiguration. I'm not sure where it's coming from and it only contains the appsettings.json, and not my azure one that i passed into the original builder. can anyone advice if there's some way to force it to use the configuration I provided?

This works completely automatically for us with the ootb Umbraco project template. Order of configuration is Azure environment variables > ASPNETCORE_ENVIRONMENT-specific appSettings > appSettings. Did you make any modifications to the ootb template? What does "my azure one that i passed into the original builder" mean?

#

So this is where i'm passing in the configuration. you can see the provider for AzureAppConfiguration which has my conn string in it

#

when debugging the AddUmbraco(_env, _config) i can see that it is using this fine

#

#

But when it goes into the .AddbackOffice() and gets to the same bit of code again it has completly different IConfiguration

#

#

I have no idea where it's pulling in that second iconfiguration from as i'm not setting or providing it

#

it first looks in appSetttings.Development.json and then appSettings.json - so if a connection string is specified there it will take that one.

#

It also looks in windows secrets first, in case that one is set

versed tulip Jul 10, 2024, 9:27 AM

#

Yes. so when i put the conn string back into the appsettings it works perfectly. but when it's not there it doesn't seem to like getting it from my azure app configuration.

lament olive Jul 10, 2024, 9:29 AM

#

Don't really know how to set that up, but doesn't it read what azure app configuration to use from the appSettings file as well?

versed tulip Jul 10, 2024, 9:29 AM

#

it's especialy strange as stepping into it i can see it works the first time when inside the AddUmbraco() extension but when it gets to the addBackOffice() it seems to have a different set of config providers

lament olive Jul 10, 2024, 9:29 AM

#

If you only put that in your appSettings.Production.json file then it doesn't know to use it

versed tulip Jul 10, 2024, 9:31 AM

#

I'm not sure i follow sorry.
the config for azure app configuration is in the appsettings.json if that's what you mean

#

when debuging i can see that that has worked and the secret is available via that provider

#

lament olive Jul 10, 2024, 9:31 AM

#

yeah okay that seems fine then! In which case.. no idea, sorry

versed tulip Jul 10, 2024, 9:31 AM

#

Yeah it's a real mystery

lament olive Jul 10, 2024, 9:32 AM

#

what happens if you install Umbraco when asked on local? which database does it use?

versed tulip Jul 10, 2024, 9:40 AM

#

If i point it to the db seems to do the install but next time i try to run it same issue.

#

it seems to be unable to find the sql on startup. which makes sense from what i've seen stepping through the code etc

lament olive Jul 10, 2024, 10:05 AM

#

Yeah if there's no connection string then it will ask what database to use, that makes sense. But then it should update the appsettings file and run from the same db the next time though.

#

I'm still wondering if you made any changes to the ootb Program.cs since this usually works automatically 🙂

versed tulip Jul 10, 2024, 12:51 PM

#

no changes to the ootb program.cs etc. using defaults

daring dock Jul 11, 2024, 8:23 AM

#

What's the aspnetcore_environment in Azure?

versed tulip Jul 11, 2024, 8:29 AM

#

"Development", But this is when running it localy in vs on on azure itself yet.

daring dock Jul 11, 2024, 8:30 AM

#

Where is the connection string declared when running locally in VS?

versed tulip Jul 11, 2024, 8:30 AM

#

Just to clarify when we use the umbraco method for getting the conn info from our _config it is retrieving the correct value

#

the conn string is being read for an azure appConfiguration service in azure

daring dock Jul 11, 2024, 8:31 AM

#

versed tulip the conn string is being read for an azure appConfiguration service in azure

When running locally from VS? How?

versed tulip Jul 11, 2024, 8:31 AM

#

We bring into the enviroment variables as a provider like so

daring dock Jul 11, 2024, 8:32 AM

#

Hmm. Why are you doing it this way?

#

Is it because you want to "move our configuration out of app settings and into azure app configuration and key vault for secrets" even for local development?

versed tulip Jul 11, 2024, 8:33 AM

#

yeah

daring dock Jul 11, 2024, 8:33 AM

#

Why not just use user secrets for local development, and key vault for Azure?

versed tulip Jul 11, 2024, 8:34 AM

#

We have inconsistant config localy amoung the team and we're standadising it so that when running localy we will simple bring down configs labeled development. when running in test we bring down labeled test, sandbox for sandbox and prod for prod etc

daring dock Jul 11, 2024, 8:34 AM

#

versed tulip We bring into the enviroment variables as a provider like so

Where exactly is the development configuration declared in Azure?

versed tulip Jul 11, 2024, 8:35 AM

#

in the appconfiguration service. we're using labels to differentiate the different configs

daring dock Jul 11, 2024, 8:35 AM

#

You mean this, right? https://learn.microsoft.com/en-us/azure/azure-app-configuration/quickstart-azure-app-configuration-create?tabs=azure-portal

versed tulip Jul 11, 2024, 8:37 AM

#

#

so that's part of the configuration on appconfiguration

daring dock Jul 11, 2024, 8:38 AM

#

So, in actual Umbraco runtime the Azure App Configuration config source isn't being used, which leads to the "Umbraco not installed" problem. But you can see in code that the config source actually works, even when using Umbraco methods to retrieve configuration.

versed tulip Jul 11, 2024, 8:38 AM

#

this works fine the variables are available they have the same key, and when running _config.GetUmbracoConnectionString(out var name); we get the correct value

daring dock Jul 11, 2024, 8:38 AM

#

If you define a connection string in appSettings.Development.json, does Umbraco recognize that?

versed tulip Jul 11, 2024, 8:39 AM

#

yeah so if i put the conn string into appsettings it works fine

daring dock Jul 11, 2024, 8:40 AM

#

How does Umbraco retrieve the DefaultAzureCredential? When you run locally, it would use your user credentials?

versed tulip Jul 11, 2024, 8:40 AM

#

when debuging the umbraco i can see that when it runs the AddUmbraco(_env, _config) extension it is getting the correct conn string but later when it's running the .AddBackOffice() it gets a completly different IConfiguration

#

yeah we use our azure creds

#

#

this is where we're setting up umbraco

#

the AzureAppConfigurationProvider in _config is from azure app configuration and has the conn string in as expected

daring dock Jul 11, 2024, 8:49 AM

#

Have you tried doing .AddAzureAppConfiguration before .AddConfiguration?

versed tulip Jul 11, 2024, 8:50 AM

#

I have. i was wondering if perhaps it was taking a .first() of the providers at some point myself

#

no luck same result

daring dock Jul 11, 2024, 8:51 AM

#

This sounds like a bug in Umbraco. No idea why .AddBackOffice would somehow get configuration without one of the configuration providers. But it does sound like a timing issue.

versed tulip Jul 11, 2024, 8:52 AM

#

Thanks for your help anyway I appreciate your time.

#

It's a real mystery though 😦

daring dock Jul 11, 2024, 8:53 AM

#

No problem. Thanks for the App Configuration idea, it looks like something that could be useful to us as well.

versed tulip Jul 11, 2024, 8:53 AM

#

If i get it working i'll let you know

daring dock Jul 11, 2024, 8:53 AM

#

versed tulip Thanks for your help anyway I appreciate your time.

Yes, the only thing I can think about is the Umbraco bootstrap pipeline doing something that invalidates one of the chained configuration providers during AddBackoffice for some reason.

versed tulip Jul 11, 2024, 12:06 PM

#

Potentialy fixed it.

So Umbraco does apear to be using the service provider to get the IConfiguration somtimes instead of the one i passed into it when making the builders. so i've replaced the iconfiguration service in service provider with my IConfiguration

services.Replace(ServiceDescriptor.Singleton(typeof(IConfiguration), _config));

And that seems to have worked.

daring dock Jul 11, 2024, 12:50 PM

#

oof. That's definitely a bug I'd say
