How to connect docker container to bitcoin node?

I have a python script inside docker container and a bitcoin node outside of docker in my local machine , this is my bitcoin.conf information

Code:

rpcuser=testuser
rpcpassword=testpassword
testnet=1
prune=550
server=1
[test]
rpcallowip=0.0.0.0/0
rpcport=8332
bind=127.0.0.1
minconf=1

and this is my docker compose conf file

Code:

app:
build:
context: .
restart: always
volumes:
- .:/app
extra_hosts:
- "host.docker.internal:host-gateway"

then in my python script i'm trying to connect to the bitcoin node using this:

connection_url="http://%s:%s@localhost:8332/wallet/testwallet"
credentials=('testuser','testpassword')
rpc_connection = AuthServiceProxy(connection_url % credentials)
rpc_connection.getnewaddress()

when I make call to this script I get this error in return [Errno 111] Connection refused

Ps: when I run the same script outside of docker container it works fine Any solutions?? ++ is it safe to run the node and connect to it using a script like this? locally?
