Update: With debug=1 I could verify that 127.0.0.0:18332 was being binded, not [::1]:18332 but I dont care I could verify that local connection inside the docker with bitcoin-cli works Now the problem is that I cant use the rpc outside the docker I don't know why Probably isn't a Bitcoin issue

Update: Confirmed, not bitcoin problem, I tried with another docker image and seems working: https://hub.docker.com/r/ruimarinho/bitcoin-core

@mrbianchi The reason it's working is it's using version 0.16. There was a change in version 0.18 that requires the use of rpcbind parameter.

Before 0.18, if you put rpcallowip=0.0.0.0/0, the value of rpcbind didn't need to be set as it defaulted to all interfaces.

Now that is no longer the case. Here's my setup, for running bitcoind in a container through Docker compose:
```
rpcallowip=0.0.0.0/0
rpcbind=127.0.0.1
rpcbind=<local DNS name, such as the container name used in your Docker Compose file>
```
The first rpcbind is so I can make RPC calls from inside the container. The second is so other containers can reach the bitcoind container.

@chanhosuh you are right! I tested. Documentation should be updated. Additionally, I had to add [test] section in file bitcoin.conf because is mandatory for testnet
```
server=1
rpcallowip=0.0.0.0/0
rpcuser=admin
rpcpassword=admin

[test]
rpcbind=127.0.0.1:18332
rpcbind=172.18.0.30:18332
```

Update: Confirmed, not bitcoin problem, I tried with another docker image and seems working: https://hub.docker.com/r/ruimarinho/bitcoin-core @mrbianchi I am trying from a while with 0.18.1 bitcoin-core version but RPC not working. My commands =
1. Start docker conainer = docker run --rm --name bitcoin-server -it btc-19nov
  -printtoconsole
  -regtest=1
  -rpcbind=127.0.0.1
  -rpcauth=
2. Initiate RCP call from base Ubuntu 18.04 LTS machine = docker run -it --rm btc-19nov
  bitcoin-cli
  -rpcconnect=bitcoin-server
  -regtest
  -rpcuser=amey
  -stdinrpcpass
  getbalance
Error = error: Could not connect to the server bitcoin-server:18443

Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

Any hints how to solve this issue?

I am using = Docker version 19.03.4, build 9013bf583a Base OS = Ubuntu 18.04 LTS

If I telnet to localhost using the bind port, I get message connection refused. For other docker app if I telnet on different port, it works!
