How to get Docker image build logs?

[punkpeye]

This is what I am doing at the moment, but it feels like I am way too deep into this and there should be a simpler way?

const stream = await docker.buildImage(
  {
    context: temporaryDirectory,
    src: ['Dockerfile', ...(files?.map((file) => file.name) ?? [])],
  },
  {
    t: tag,
    version: '2',
  },
);

const logs: string[] = [];

await new Promise((resolve, reject) => {
  docker.modem.followProgress(
    stream,
    (error, response) => {
      if (error) {
        reject(error);
      } else {
        resolve(response);
      }
    },
    (event) => {
      if (!isObjectLike(event)) {
        reject(new UnexpectedStateError('Expected event to be an object'));

        return;
      }

      if ('error' in event) {
        reject(
          new DockerBuildError('Build failed', {
            error: event.error,
            logs: logs.join('\n'),
          }),
        );

        return;
      }

      if (isBuildkitTraceEvent(event)) {
        const log = Buffer.from(event.aux, 'base64').toString();

        if (log) {
          console.log('log', log);

          logs.push(log);
        }

        return;
      }

      if (isImageIdEvent(event)) {
        return;
      }

      reject(
        new UnexpectedStateError('Expected event to be an object', {
          event,
        }),
      );
    },
  );
});
