Topic: How to connect docker container to bitcoin node? (Read 177 times)
host.docker.internal is a domain name not an IP address. You need the IP address of the Docker container because bitcoin-cli doesn't do address resolution when connecting to the RPC server. You can find it using such tools as "ip addr" that show all the network interfaces - it will be called "docker0" or something like that.
Another thing could be your server configuration because you need to one the port in the farewal to give access to the RPC calls.

The way i did to personally fix this kind of issues in my local servers was with the command:
And to verify your open ports you can use nmap:

Code:
firewall-cmd --zone=public --add-port=8332/tpc --permanent
And to verify your open ports you can use nmap:
Code:
nmap localhost
You should use the internal IP on the Python container, not localhost.
If it still not works, try refer to https://www.howtogeek.com/devops/how-to-connect-to-localhost-within-a-docker-container/
Code:
connection_url="http://%s:%[email protected]:8332/wallet/testwallet"
credentials=('testuser','testpassword')
rpc_connection = AuthServiceProxy(connection_url % credentials)
rpc_connection.getnewaddress()

internal ip like 127.0.01? but that will connect to docker localhost network not the server localhost?
I meant the internal IP of Docker.
Since you already set host.docker.internal:host-gateway, you can try to use host.docker.internal as the IP, to access the IP outside Docker container.
Try to use the modified code as I quoted above.
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??

I only use docker to run certain application, but AFAIK you got this error because you didn't perform port forwarding. On terminal, i'd use parameter -p HOST_PORT:CONTAINER_PORT (should be -p 8332:8332 in your case) to perform port forwarding. But i don't know the equivalent for Dockerfile.
++ is it safe to run the node and connect to it using a script like this? locally?
Since you're the one who create the script, it should be safe. But if you have very serious security concern or writing script for business/enterprise usage, i'd recommend you to check whether library you use is malicious or not.
So running on local and connecting to rpc on local is safe, just i have to check the python library that's all?
How do i know that this library "https://github.com/jgarzik/python-bitcoinrpc" is safe?

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
and this is my docker compose conf file
then in my python script i'm trying to connect to the bitcoin node using this:
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?
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:
