Node.js GOT Docker unix socket stream error

[bllmo]

Describe the bug

• Node.js version: v16.10.0
• OS & version: macOS Big Sur 11.6

Actual behavior

Hello i have this code for attach a specific container with GOT and retrive log stream (according to docker documentation)

Code to reproduce

const got = require("got");

(async () => {
  const stream = await got('unix:/var/run/docker.sock:/containers/efbb049e620f/attach', { 
    method: 'post',
    searchParam: {
      stream: true,
      stdin: true,
      stdout: true,
      stderr: true,
    },
    isStream: true
  });

  stream.on('data', console.log);
})();

but when i run this code i dont see any log in the console, how i can resolve this?

Checklist

• [ x] I have read the documentation.
• [ x] I have tried my code with the latest version of Node.js and Got.

It doesn't show anything because you didn't send your data.

Hi @szmarczak, if i use dockerode attach command and I run it with the same params I see docker container logs into the console.

I test my got code with httpbin socket endpoint and it works.

apparently, it doesn't work with unix sockets

I think you're doing something wrong. We have tests for unix sockets and they pass.

resolved! I put an empty json object to the request.

const got = require("got");

(async () => {
  const stream = await got('unix:/var/run/docker.sock:/containers/efbb049e620f/attach', { 
    method: 'post',
    json: {},
    searchParam: {
      stream: true,
      stdin: true,
      stdout: true,
      stderr: true,
    },
    isStream: true
  });

  stream.on('data', console.log);
})();
