I’m silly, overlooked that the API wants the data and not the path/url to cert files. Here is the code fragment that works for me:

const DOCKER_CERT_PATH = process.env.DOCKER_CERT_PATH || false

let dockerCon

function util (connection) {
  if (typeof connection !== 'object') {
    throw new Error('Error: docker connection string is faulty, please review command line arguments.')
  }

  if (!connection.hasOwnProperty('socketPath') && !connection.hasOwnProperty('host')) {
    // attempt honoring the DOCKER_HOST variable, and fallback to connect using the
    // the docker daemon socket
    if (DOCKER_HOST) {
      const parsedUrl = parseUrl(DOCKER_HOST)
      let parameters = {host: parsedUrl.hostname, port: parsedUrl.port};

      if (DOCKER_CERT_PATH) {
        const base = new url.URL(DOCKER_CERT_PATH.endsWith('/') ? DOCKER_CERT_PATH : DOCKER_CERT_PATH + '/', 'file://');
        ['ca', 'cert', 'key'].forEach(
          function (fileName) {
            const fileUrl = new url.URL(fileName + '.pem', base)
            const data = fs.readFileSync(fileUrl)
            if (data) {
              parameters[fileName] = data
            }
          })
      }
      dockerCon = new DockerLib(parameters)

    } else {
      dockerCon = new DockerLib({socketPath: DOCKER_SOCKET})
    }
  } else {
    dockerCon = new DockerLib(connection)
  }
}
