Strange behaviour after fetching 1MB file from S3 in Lambda function (Node.js)

[bushev]

Steps:

1. Create a bucket
2. Deploy Lambda function (~20MB) with ffmpeg
3. Call ffprobe using S3 signed URL:

const input = s3.client.getSignedUrl('getObject', {
    Bucket: 'my-bucket',
    Key: 'video_1mb.mp4',
    Expires: 1000
})

const metadata = await (new Promise((resolve, reject) => {

    ffmpeg.ffprobe(input, async (err, data) => {

      if (err) {

        return reject(err)
      }

      resolve(data)
    })
}))

4. Stop & Destroy all containers and images
5. Remove Localstack directory ./localstack
   // Repeat 1 - 5 (~5 times)
6. Start localstack
7. Try to create the S3 bucket
8. Got a timeout error:

make_bucket failed: s3://my-bucket Read timeout on endpoint URL: "http://localhost:4572/my-bucket"

Workaround: Restart Docker daemon
