I have a use case where I'd like to launch a job on an Azure Container Service cluster to process a file being uploaded to Blob storage. I know that I can trigger an Azure Functions instance from the upload, but I haven't been able to find examples in the documentation of starting a job within Functions.
This diagram illustrates the AWS equivalent of what I want:
Thanks!
The Azure Event Grid feature is what you need. It is still in preview, but you can subscribe to the Blob Created event. You can set the subscriber endpoint to an Azure Function that puts a message in a queue to trigger your job, or you can expose a service on your cluster that will accept the request and do whatever you need done.
Microsoft provides a guide at https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-quickstart?toc=%2fazure%2fevent-grid%2ftoc.json#create-a-message-endpoint

I created an Azure logic app for running my actions from my application.
so my requirement is to upload the blob to the shared folder from Azure blob.
for that my team is created azure data factory pipeline,
so from the logic app designer I am running the trigger when the blob is added or modified, I need to run the pipeline from the azure data factory,
while running the trigger, the trigger is fired successfully but it is running at the blob only it is not going to the second action.
can you please give me the guidance how should I resolve the issue.
Azure data-factory provides the option of azure blob trigger which will work automatically. When new blob gets added your pipeline will run.
Data Factory Event Trigger
In this case you don't need separate logic app for the triggering event.
We want to configure schedule backup for database.
We have set storage account and access key for Azure Blob in security-> Credentials for Azure.
In backup directory, when enter azure://containName
This container name is exist in given storage account.
In response it says
The directory azure://backup/ does not exist on host ml01. Would you like to try and create it?
Can anybody please help me to configure?
It sounds like you want to create a work job which backup the data of your MarkLogic Database to Azure Blob Storage and trigger by a time schedule. Right? I do not completely understand what you said, so here just my suggestion below.
I'm not familar with MarkLogic, but I think you can write a script for NodeJS or a Java program to do the backup work, after I read the tag info for marklogic and I see it supports the client API for Node and Java.
As I known, there are three ways normally to deploy it on Azure if you are ready to backup in programming.
You can deploy it as a webjob with a cron expression to trigger the backup work, please refer to the offical document Run Background tasks with WebJobs in Azure App Service.
You can deploy it as a Web API on Azure by using the service like WebApp, and use Azure Scheduler to trigger it.
You can deploy it as an Azure Function and trigger it with timer trigger, please refer to the offical document Create a function in Azure that is triggered by a timer.
Ofcourse, there are other services can help to realize your needs. I don't know what the best for you is. If you have any concern, please feel free to let me know.
I was running into similar issue and was able to resolve it.
Create something side your container within a folder. so your structure should look like this
azure://containername/folder
I just was able to resolve my issue by doing that.
Is it possible to use some ready made construct in azure cloud environment to ingest the events (in json format) that are currently stored in azure blob storage and have it submit those events directly to azure event hub without writing any (however small) custom code? In other words, I would like to use configuration driven approach only.
Sure. You can try to use Azure Logic Apps to realize your needs without any code or just with some function expressions, please refer to the offical documents of Azure Logic Apps to know more details.
The logic flow is as the figure below.
You can refer to my sample below to make it works.
Here is my sample to receive an event from my EventHub and transfer to Azure Blob Storage to create a new blob for storing the event data.
Create an Azure Logic App instance on Azure portal, it should be easy for you.
Move to the tab Logic app designer to configure the logic flow.
Click Save and Run buttons. Then, use ServiceBusExplorer (downloaded from https://github.com/paolosalvatori/ServiceBusExplorer/releases) to send event message and check whether new blob created using AzureStorageExplorer. It works fine after a few minutes.
I've got some image processing code that I need to run in Azure. It's perfect for an Azure Function, but unfortunately requires a component with a complex installation procedure and therefore will need to run in a VM.
However, I'd like to make it behave much like an Azure Function, and trigger whenever new items arrive in blob storage.
My question is: Does Azure provide me with any handy way of doing this, or do I have to write code that polls the blob storage looking for new items?
Have a look at Azure WebJobs SDK. It shares API model with Functions, but you can host it in any .NET application. Blob Trigger.
I'm trying to figure out if Azure Blob Storage has similar functionality to Amazon S3. An S3 bucket can be configured in a way, that when new object is created, bucket sends message to SQS. I'm wondering if Azure Blob Storage is able to do the same with Azure Service Bus (which is kind of similar to SQS, correct?).
The only resource I've found so far, which mentions something similar is https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview, but there is no Azure Service Bus on the right side. I know I can use Functions as a proxy, but I'm interested in direct connection.
Any ideas?
Service bus(I think you compare service bus with SQS and SNS in AWS) don't have the ability to subscripe to Blob storage events. Event Grid(the link that you reffered to has Service bus support on the roadmap but no date is confirmed.
I think your best choice is Azure Functions(or Logic app if you don't want to write code) that has a blob Storage trigger to catch events and do action X.
https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-storage-blob-triggered-function.
Or wait a litte for event grid but you still get that "proxy" part.
One option is to use logic apps/ event grid and you can add trigger directly from azure blob storage (https://azure.microsoft.com/it-it/blog/azure-service-bus-now-integrates-with-azure-event-grid/) . Another option would be to add blob trigger with azure functions and write the code to do whatever action which you are looking for .
