Error: connect ECONNREFUSED

[ether-wan]

Hello, i'm trying to launch container w/ dockerode on Mac OS

const docker = new Docker({host: 'http://0.0.0.0', port: 3000, socketPath: '/var/run/docker.sock'});

    const container = await docker.createContainer({
        Image: 'app-bot',
        HostConfig: {
            PortBindings: {
                [`${3000}/http`]: [{ HostPort: 50000 }]
            }
        }
    });
    await container.start();

I'm getting an error :

Error: connect ECONNREFUSED 0.0.0.0:3000 at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1247:16) { errno: -61, code: 'ECONNREFUSED', syscall: 'connect', address: '0.0.0.0', port: 3000 }

The docker service run with colima ( https://github.com/abiosoft/colima )

The deployment of the image works with docker run -p 50000:3000 app-bot command on the terminal

Thanks !!

you also need to use ExposedPorts along with PortBindings

Thanks @danisharora099 for your reply. I'm not sure where I should use ExposedPorts, can you give me an example please

          [`${3000}/http`]: {},
        },
      });
    await container.start();

Also, not sure if /http is a supported protocol. You could probably get away with subsituting http with tcp

it doesn't work for me, I still get the ECONNREFUSED error. Are there any specific permissions to give ?

Error: connect ECONNREFUSED 0.0.0.0:3000

  port: 3000
}

Did you try it with /tcp? @reptincel-cpu
