Fix docker image v6.1.6+

[levino]

Using this docker-compose.yml:

version: '3.2'
services:
  dev-blockchain:
    image: trufflesuite/ganache-cli:v6.1.6
    ports:
      - 8545:8545

I cannot connect to localhost:8545. Last working version is 6.1.3. The difference is in the logs:

• Version 6.1.3 says: Running on localhost:8545 (which actually means 0.0.0.0:8545 I guess)
• Version 6.1.6 says: Running on 127.0.0.1:8545 (which seems to really mean that it only listens on 127.0.0.1 but that is very wrong in docker, because it is now running in a container and the port can only be reached from outside or the network if the service binds to the interface 0.0.0.0)

Remark: Using -h 0.0.0.0 does not work, gives some error about eadrr not found.

I have the same issue. Update: actually -h 0.0.0.0 works. Here is my docker-compose.yml:

version: "2.1"

services:
  ganache:
    image: trufflesuite/ganache-cli:v6.1.6
    ports:
      - 8545:8545
    entrypoint:
      - node
      - ./build/cli.node.js
      - --host=0.0.0.0
      - --port=8545
      - --gasLimit=7992181

[levino]

It has to be -h=0.0.0.0. Here is my also working docker-compose.yml

version: '3.2'
services:
  dev-blockchain:
    image: trufflesuite/ganache-cli:v6.1.6
    ports:
      - 8545:8545
    command: ["-h=0.0.0.0"]

Closing as "weirdly implemented but kinda works as expected".

Adding some keywords to help folks find this (took me a while to get here). Thanks @Levino @Zorato for posting the fix on this.

ganache-cli docker metamask unknown network ports can't connect

Further, we addressed this issue in #559. In the next release of ganache-cli (and its Docker container), the host should default to 0.0.0.0 for Docker instances
