=== Usage
For local Azure Storage development you need https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azurite?tabs=visual-studio[Azurite emulator].
For the emulator you can run a docker container (see below) or use the https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azurite?tabs=visual-studio-code[Visual-Studio-Code extension].
Here is how to start the `Azure emulator` as docker container:
[source,shell]
----
docker run --name azurite --rm -p 10000:10000 -p 10001:10001 -p 10002:10002 mcr.microsoft.com/azure-storage/azurite

./mvnw azure-functions:run
----
NOTE: To run locally on top of `Azure Functions`, and to deploy to your live Azure environment, you will need `Azure Functions Core Tools` installed along with the Azure CLI (see https://docs.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-java?tabs=bash%2Cazure-cli%2Cbrowser#configure-your-local-environment[here]).
Use the https://azure.microsoft.com/en-us/products/storage/storage-explorer/[Azure Storage Explorer] to access the Emulator Storage Account.
NOTE: https://github.com/Azure/azure-functions-core-tools[Azure Functions Core Tools] version `4.0.5030` or newer is required!
Under the `Blob Containers` create 3 new containers: `test-trigger`, `test-input`, `test-output`.
Then upload the `src/test/resource/sample.txt` file into the `test-input` and the `test-trigger` folders in this order.
For some configuration you would need the https://learn.microsoft.com/en-us/azure/storage/common/storage-use-emulator[Azurite emulator] as well.
The appearance of the `sample.txt` file in the `test-trigger` folder triggers the `blobTest` function handler, that would look up for a file with the same name (because we used the `{name}` convention in the @BlobInput path) from the `test-input` folder.
Later is passed through the auto-wired `uppercase` service and the result is saved in the `test-output` folder.
Verify that the newly created file in `test-output` is in capitalized letters.

Authoritarianism begins when we can no longer tell the difference between the true and the appealing.
At the same time, the cynic who decides that there is no truth at all is the citizen who welcomes the tyrant.
