Deploy new/ updated application version to Azure Batch Services via RESTful API?

Question

I'm building a console app that is designed to scale in an Azure Batch Service, but I can't seem to figure out how I can update the batch service application programmatically.

I've been looking at the API reference at https://learn.microsoft.com/en-us/rest/api/batchmanagement/ which has options to create, update, and modify applications for the batch service... but I don't see how to actually push the new binaries to the batch service, or how to tell the batch service the blob location of the new binaries. Am I missing something obvious?

Answer 1

Cool, I think you should add more information for the specific design scenario you have. I have added the API and have also detailed few things which might help in better understanding and also sorry if I missed anything obvious :).

Down below, as an example I came out with one possible scenario and answered it as thinking out loud process.

WRT (With respect to) the question:

• How are your new binaries generated? and Do you manage them on the fly?

• create, update etc: please refer to the following doc which talks about the create, delete, or update : https://learn.microsoft.com/en-us/rest/api/batchmanagement/application

• https://learn.microsoft.com/en-us/rest/api/batchmanagement/pool/update
• some sample reference for update \ create: https://github.com/Azure-Samples/azure-batch-samples/blob/master/CSharp/AccountManagement/Program.cs#L241
• Most of the samples reside here for idea sake : https://github.com/Azure-Samples/azure-batch-samples/tree/master/CSharp

Coming back to the more information part: (Reason I ask is to get clarity for the design how app is trying to utilize resources etc...) a really good over all intake on resource management et. al. here https://learn.microsoft.com/en-us/azure/batch/batch-api-basics .

More information which should be though for scaling reasons are like:

• Your application creates pool with certain amount of resource or packages at pool level or task level?
• How are you managing your resources?
• What scenario will require a binary update: i.e. will it be in the middle of the task getting run or something else?

Sample Scenario which comes to my mind

Say for example:

My pool is running 20 tasks, task 1 generates the binary which will get used in task 4 then 2 concepts comes to my mind first : my tasks are dependent tasks so look for this concept, then I can do upload files form my tasks using output file concept here, then I use the new uploaded files in my task now.

Hope this helps. Thanks!
