Bug: Azurite unable to run create_container

[jasonlmfong]

Describe the bug

when using a Blob Service Client on a Azurite container, an azure blob storage container cannot be created, thus testing that requires containers cannot continue. E.g. get_blob_client and upload_blob requires a container.

To Reproduce

Provide a self-contained code snippet that illustrates the bug or unexpected behavior. Ideally, send a Pull Request to illustrate with a test that illustrates the problem.

The last line here just hangs indefinitely, unable to proceed further

from azure.storage.blob import BlobServiceClient
from testcontainers.azurite import AzuriteContainer

with AzureContainer() as azurite_container:
    connection_string = azurite_container.get_connection_string()
    service_client = BlobServiceClient.from_connection_string(connection_string)
    service_client.create_container(name="test")

Runtime environment

• M2 Pro, sonoma 14.7
• Python 3.12.3
• Docker 4.37.2
• Testcontainers 4.9.0 (via poetry)

Hej I am not completely sure but. I guess you are NOT testing inside docker (DIND),

I have bumped into a similar issue, my hacky solution was to modify the get_connection_string function of the AzuriteContainer

def get_connection_string(self) -> str:
        host_ip = self.get_container_host_ip()
        if host_ip.lower() == "localhost":
            host_ip = "127.0.0.1"

the gist of this change is to use 127.0.0.1 instead of localhost I am not sure why this works though.

If i spin up an azurite container using docker compose and use a port on the same range as testcontainters. I am able to use both localhost and 127.0.0.1

@David2011Hernandez nice, this hack actually works for me

I'm leaving this issue open since the hack requires me to fork the package and change stuff
would like to see it get patched officially

do you have this line in your /etc/hosts (c:\Windows\System32\Drivers\etc\hosts)?

127.0.0.1 localhost

[jasonlmfong]

you're right, I do have this in my /etc/hosts, I don't remember ever adding it though, might have other implications if i remove it

[alexanderankin]

ok if you have this line and it still doesn't work some kind of other assumption is wrong and it may be a bug.

[alexanderankin]

im going to look into this on sonoma as well and see if i can fix

for context, when I run this test in github actions (running on ubuntu 24.04.1), it passes fine
