Is it not recommended to use firebase local emulator in container?

[yamato-araki]

Sorry for my poor English.

I use firebase local emulator in docker container.

my firebase.json

{
  "firestore": {
    "rules": "firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "emulators": {
    "auth": {
      "host": "0.0.0.0",
      "port": 9099
    },
    "firestore": {
      "host": "0.0.0.0",
      "port": 8080
    },
    "ui": {
      "host": "0.0.0.0",
      "enabled": true
    },
    "functions": {
      "host": "0.0.0.0",
      "port": 5001,
      "debugPort": 9229
    },
    "singleProjectMode": false
  },
  "functions": [
    {
      "source": "functions",
      "codebase": "default",
      "ignore": [
        "node_modules",
        ".git",
        "firebase-debug.log",
        "firebase-debug.*.log"
      ],
      "predeploy": [
        "npm --prefix \"$RESOURCE_DIR\" run lint",
        "npm --prefix \"$RESOURCE_DIR\" run build"
      ]
    }
  ]
}

I start emulator .

firebase emulators:start --inspect-functions

but console output

Debugger listening on ws://127.0.0.1:9229/b8a5893d-24db-446b-aa01-fc0a440f6ee1

I need to bind to 0.0.0.0.

I expect output

Debugger listening on ws://0.0.0.0:9229/b8a5893d-24db-446b-aa01-fc0a440f6ee1

So, I read forebase-tools source code.
I found this line.

args.unshift(`--inspect=${connectableHostname(host)}:${this.args.debugPort}`);

and I check connectableHostname function.

this is connectableHostname function.

/**
 * Return a connectable hostname, replacing wildcard 0.0.0.0 or :: with loopback
 * addresses 127.0.0.1 / ::1 correspondingly. See below for why this is needed:
 * https://github.com/firebase/firebase-tools-ui/issues/286
 *
 * This assumes that the consumer (i.e. client SDK, etc.) is located on the same
 * device as the Emulator hub (i.e. CLI), which may not be true on multi-device
 * setups, etc. In that case, the customer can work around this by specifying a
 * non-wildcard IP address (like the IP address on LAN, if accessing via LAN).
 */
export function connectableHostname(hostname: string): string {
  if (hostname === "0.0.0.0") {
    hostname = "127.0.0.1";
  } else if (hostname === "::" /* unquoted IPv6 wildcard */) {
    hostname = "::1";
  } else if (hostname === "[::]" /* quoted IPv6 wildcard */) {
    hostname = "[::1]";
  }
  return hostname;
}

This comment say

This assumes that the consumer (i.e. client SDK, etc.) is located on the same device as the Emulator hub (i.e. CLI)

So, Is it better not to use firebase local emulator in container?
