问题
I am using azure functions with the blob trigger and with the runtime 2.x. After the function being executed the runtime adds blob receipt into the location below (azure-webjob-hosts>blobreceipt>)
Is there any way to make runtime to use the same hostnameid in the path (in this case it's 8a76f42c1c01-2137340777)? Because if run function locally or publish new version of the code it would use different host identifier (like macbook-id).
The main problem is when I run func azure functionapp publish it will requeue all the existing blobs with new version of the code even when the new version has the same func name because it will use different host/func identifier to check for receipts.
I know that in runtime v1 you could add id into host.json. I dont see such option in runtime v2.
Edit:
Another thing. Just this morning I found out that my function run over all the blobs again. When I looked into blobreceipts I see that the hostid has changed and there are new bunch of receipts for the new host id. Host Id has changed even though I didnt do any deployments. How is that possible? I have also reported the bug on coretools about hostid getting changed on publish. https://github.com/Azure/azure-functions-core-tools/issues/1012
App name is altamente-prod-svc-shopify-background. But the host id is d7031c9b43fc-2137340777. I have removed all receipts to do more tests for now but you can see in logs that the func was initiated again this morning by itself over all my 7 blobs. There is just one function for now (and also WarmUp func which appeared automatically). I have created the linux func app via Azure portal with no functions and then just did publish with core tools from my mac.
回答1:
There is a workaround now in the Azure Functions bug report that you linked to. Basically, set AzureFunctionsWebHost:hostid in the App settings to some explicit value. I'm using a self-hosted functions runtime and Kubernetes doesn't allow colons in environment variables, so I used the work-around of setting AzureFunctionsWebHost__hostid instead, which also works.
