Azure Functions App is Read Only after publishing - azure

I have several Azure Functions Apps (c#, javascript and python) and after some time they were all randomly set to Read Only mode. The strange thing is that only one of these 3 function apps were updated before this happened. I know that this is not necessarily a problem, but I want to be able to make edits from the portal.
I can't open App Service Editor
I can't set the app to Read/Write from Function App Settings -> Function app edit mode
I also tried using "func azure functionapp publish myAzFuncAppName --nozip", but with the same result

Of course. Please notice that if the function is 'deployed' to Azure, what will be deployed is the compiled file.
For example, if you deploy C# function app, what will be deployed is the dll file. So this is why it is readonly.
Changes to the code should be done before compiling them into corresponding 'cannot be edited' files, which requires special attention.
But for the modification of the declarative part and the configuration part of the function, this is possible, the specific steps are as follows:
Declarative part:
Then click Debug Console > cmd:
Go to site\wwwroot[yourfunctionname], and there will be a function.json.
Click the 'pen' to edit and don't forget to save.
Configuration part:

You can change the settings from Azure Portal or by editing the application settings. FUNCTION_APP_EDIT_MODE allows values readwrite and readonly, a

Just deleted the Azure Function App, created a new one, transferred the code in the new one and deployed -> still read only, but now I was able to open "App Service Editor" and remove "generated by..." from function.json and then set "Read/Write" from Function App Settings -> Function app edit mode.
Still... I can't see/edit the code of the function, only of function.json and if I redeploy using Azure extensions of Visual Code or powershell with --nozip attribute, the "generated bla bla" appears again :(

When the application runs from package, the files are loaded from that package. Hence those files are not editable.
You need to set WEBSITE_RUN_FROM_PACKAGE : 0 in app settings and redeploy the application again to make the function app editable.

UPDATED:
You can deploy functionapp through command line from visual studio code. Try below command.
func azure functionapp publish --nozip
The nozip flag would set Run-From-Package mode off .
you can access other information regarding that command with func azure functionapp publish --help

How do I get into the folder of a Web App in Azure

Recently I am trying to use:
func azure functionapp publish WebAppName --publish-local-settings -i
to publish local.settings.json to a web app (actually an Azure function) but I get this error message:
Unable to find project root. Expecting to find one of host.json in project root.
I have logged in to Azure with az login but it looks like I need to get into the folder where I have deployed the Azure function where all those json files are.
A little background, we are using Octopus Deploy to deploy to an Azure function. After the deployment, we want to add a step so that the local.setting.json will be used to populate app settings.
So how do we change the current folder to be in the Azure function root where all those json files are?
Thanks a lot in advance!
You need to go to your local function project folder to run the command, for example, my function project is under MyFunctionProj folder.
Execute the command
func azure functionapp publish tonyfunc --publish-local-settings -i --publish-settings-only
By the way, if you just want to update the settings, you need add --publish-settings-only parameter.

Powershell / Azure Functions - Do not run at all

Got a Azure Function (Queue) with a powershell script from git source. When I click run nothing happens, se picture below!
I've set up everything on a new tenant, but one strange thing. I did not find experminental language option (powershell) when creating the Azure Functions. So I choose to get it from a source (git). I've also activated 64-bit and Managed service identity (I'm later going to use the key vault)
Removed "dotnet" from Application Settings. Think this get's in by default after they changed the settings when creating a new Azure Functions

Azure Function how to move appsettings from local to server and vice versa

I m a little new to Azure.
Issue is I m developing Azure Functions and some times I have to work locally (code/ test etc) and other times on Azure. Every time I switch I have to compare and change app settings manually.
Is there a way I can avoid it ? Something where if I run locally I may get latest from server without manual and when I go to server Azure may be aware of my changes ?
Thanks
Yes, use the Azure Functions Core Tools —
Usage: func azure functionapp <action> [-/--options]
fetch-app-settings Retrieve App Settings from your Azure-hosted
Function App and store locally Aliases:
fetch-app-settings, fetch
and
Usage: func azure functionapp <action> [-/--options]
publish Publish the current directory contents to an
Azure Function App. Locally deleted files
are not removed from destination.
<FunctionAppName> Function App name
--publish-local-settings [-i] Updates App Settings for the
function app in Azure during deployment.
--publish-settings-only [-o] Only publish settings and skip the
content. Default is prompt.
--overwrite-settings [-y] Only to be used in conjunction with -i or -o.
Overwrites AppSettings in Azure with local
value if different. Default is prompt.
There's also encryption for the local file if you feel a little adventurous —
run func settings to get usage.

How can I view the final appSettings values on an Azure App Service web app?

I have an ASP.NET MVC app deployed to Microsoft Azure App Service and am having some trouble with the appSettings and connectionStrings values.
I have some values set in the web.config and some values overriding them in the Application Settings tab of the App Service. I want to quickly and easily view the final values to check that the settings are being picked up correctly.
How can I do this?
Note: I've tried using az webapp config appsettings list but this only seems to bring back what is configured in the Application Settings of the App Service and not the merged results of combining with web.config.
No Azure API will return values that include settings that come from your web.config file.
The only way to get this is to ask the config system within your own runtime. e.g. Use code along these lines:
foreach (string name in ConfigurationManager.AppSettings)
{
string val = ConfigurationManager.AppSettings[name];
...
}
foreach (ConnectionStringSettings settings in ConfigurationManager.ConnectionStrings)
{
string connStr = settings.ConnectionString;
string provider = settings.ProviderName;
...
}
This will give you the effective values that are applied to your app.
You may also use the following blades in Azure Portal (under Development Tools section):
Console
In order to see the file, you may use type command, e.g.:
type web.config
Advanced Tools
This points to the Kudu service.
You may see files deployed when navigating to Debug Console > Choose either CMD or PowerShell. Then navigate to your config directory (e.g. site/wwwroot) and choose to either download or edit file.
App Service Editor
App Service Editor is a relatively new tool in Azure toolset. Default view is a list of files, so you can browse all hosted files, including configuration ones.
You can view all of your runtime appSettings, connection strings and environment variables (and more..) using azure KUDU SCM. if your application address is "https://app_name.azurewebsites.net" you can access it in the address "https://app_name.scm.azurewebsites.net" or from azure portal
With kudo REST API, you can get the settings, delete or post them in this address https://app_name.scm.azurewebsites.net/api/settings

Azure NodeJS console log

I have a Visual Studio Enterprise MSDN subscription so I decided to move from Heroku to Microsoft Azure because I used to pay: now I don't. My Service Plan is the D1.
I wish I can trail the console.log strings of my Node JS application deployed on my Azure platform. My service plan is the shared one named
I deployed the app code on BitBucket and linked my repo to the application with a correct destribution. Correct means I see the green check flag. I deployed, on the main folder of the app, a file named IISNode.yml, here is the content:
nodeProcessCommandLine: "D:\Program Files (x86)\nodejs\0.12.6\node.exe"
loggingEnabled: true
debuggingEnabled: false
devErrorsEnabled: false
node_env: production
The firse line I copied from the iisnode.yml created by Azure itselves. The other lines I am not quite sure about the exact meanings of all of them, but I figured they were enough. If I visit the url: http://MY_APP_NAME.scm.azurewebsites.net/DebugConsole I can click on Tools->Log Stream menu but the page remains on loading.
I can reach the Azure Portal, enter my node app, Tools -> Application Log and Web Server log. The application log shows this (I think quite interesting) message:
System.ApplicationException: The trace listener AzureBlobTraceListener is disabled. ---> System.InvalidOperationException: The SAS URL for the cloud storage account is not specified. Use the environment variable 'DIAGNOSTICS_AZUREBLOBCONTAINERSASURL' to define it.
at Microsoft.WindowsAzure.WebSites.Diagnostics.AzureBlobTraceListener.RefreshConfig()
I have not reached informations about this "environment variable", and I can0t guess what the BLOB container has to do with my log application. And: what is the correct value for this variable? And if there is any, why is that one correct?
The Web Servier log is are empty. I can see http activities from the monitor of the app on the same portal, but still no log.
Am I missing something ? I decided to install Visual Studio, maybe this will help? I hope this has tools to be integrated with Azure for good. Meanwhile, where is the console log of my (Extremely Simple) node application?
You can view your logs in real time if you use the azure SCM interface. This can usually be accessed on the following url
https://{{ name of webapp }}.scm.azurewebsites.net/api/logstream
All your console output from your application is redirected here.
You can also use curl:
curl -u {{ deploymentCredentialsUsername:deploymentCredentialsPassword }} https://webapp-name.acm.azurewebsites.net/api/logstream
Otherwise you could use the nodejs azure cli. Install it with
npm install -g azure-cli
Switch to asm mode:
azure config mode asm
Then you can proceed to look at the logs from your terminal:
azure site log tail {{ webapp name }}
You can add an item in iisnode.yml named logDirectory, set the value as iisnode for example, then the application will create a folder in this name in your root directory and store files with stdout and stderr captures in it. You can refer to https://github.com/tjanczuk/iisnode/blob/master/src/samples/configuration/iisnode.yml#L94 for the details for this configuration.
You can store logs in files whatever you need via console.log(), then the application will create a html file index.html in the log folder to provide logs. You can visit the logs via the URL: http://<you_app_name>.azurewebsites.net/<log_file_name>/index.html
Additionally, you can leverage Node.js console class to customize logger, refer to https://nodejs.org/api/console.html#console_new_console_stdout_stderr for the sample
If you are using the Azure Portal web interface, you can find the console.log output under the Log Stream section under Monitoring.
