My local (windows) azure function works fine when I start azurite in windows and use UseDevelopmentStorage=true. I can connect to the port with telnet localhost 10000 and telnet 127.0.0.1 10000.

However, when I stop azurite on windows and run it in WSL via docker the function cannot connect.

Azure.Core: No connection could be made because the target machine actively refused it. (127.0.0.1:10000). System.Net.Http: No connection could be made because the target machine actively refused it. (127.0.0.1:10000). System.Net.Sockets: No connection could be made because the target machine actively refused it.

The port is definitely open but telnet on 127.0.0.1 confirms that that binding is missing:

• telnet localhost 10000 ✅
• telnet 127.0.0.1 10000 ❌

What most be changed in docker(-compose) so that binding to 127.0.0.1 works? OR How can I tell my azure function to connect to localhost or 0.0.0.0 instead of 127.0.0.1?

docker describe azurite

 "Ports": {
  "10000/tcp": [
      {
          "HostIp": "0.0.0.0",
          "HostPort": "10000"
      },
      {
          "HostIp": "::",
          "HostPort": "10000"
      }
  ],

docker compose
