上传到S3存储桶

Question

I am new to Elastic Beanstalk, just uploaded an NodeJs app. I'm wondering if it's possible to "link" (like unix symlinks) a folder to a S3 bucket?

Make "/recordings" points to S3:

var filename = 'recordings/' + match[1] + '.wav';
      var file = fs.createWriteStream(filename);
      var request = https.get(url, function(response) {
          response.pipe(file);
          file.on('finish', function() {
            file.close();
      }).on('error', function(err) {
        fs.unlink(file);
        console.log('error downloading recording');
      });

You can use tools like s3fs-fuse to mount S3 buckets to your filesystem. However, this is generally not recommended as S3 is not designed to be used as a block storage device.

As the s3fs readme documents:

Generally S3 cannot offer the same performance or semantics as a local file system. More specifically:

• random writes or appends to files require rewriting the entire file
• metadata operations such as listing directories have poor performance due to network latency
• eventual consistency can temporarily yield stale data no atomic renames of files or directories
• no coordination between multiple clients mounting the same bucket
• no hard links

The best way to use S3 with your Node application is using the AWS SDK for JavaScript in Node.js .
