If you'd be willing to create a PR to fix them, that would be appreicated! If not, I'll see if I can get someone to verify them 🙂

im not too sure what r2 is but it seems to be like file hosting or something like that? 0.015 / GB is fire

Do you mean enabling/disabling r2.dev affects if your custom domain works or not?

Yeah

Enable r2.dev, custom domains work. Disable r2.dev status returns to “Not Allowed”

Yeah, you upload files to R2 and then serve them up. Similar to Amazon S3 and similar other products

@Sid | R2 it’s later here (UK) so i’ll jump back on here when I’m in the office tomorrow for some more support if it’s not started working by then

Hi, can I limit access some bucket for R2 API Key?

For now I see R2 API Key can access full bucket

Not currently, it's only read or write entire account atm

thanks

can i host any file on them? like .zip and jar files etc?

You can host whatever you want in terms of file type

That's right. I can confirm that.

Does anybody has experience with Apache spark reading and writing deltatables (delta.io) in production?

On r2 storage of course 😋

Does anyone have experience generating a signed URL using the example provided in the Cloudflare R2 Data Access S3 API Presigned URLs documentation https://developers.cloudflare.com/r2/data-access/s3-api/presigned-urls Specifically, I am looking for guidance on how to enforce the content length and content type restrictions when generating the signed URL. I am getting a presigned url using the following function, but it appears I can just upload any file type of any size (which is not the behavior I'm looking for).

export const generateURL = async (fileType: string, fileSize: number, config: Config) => {
  const allowed_file_size = 5
  if (Number(fileSize) / (1024 * 1024) > allowed_file_size) {
    throw Error('File too large')
  }

  const allowed_file_types = ['image/png', 'image/jpg', 'image/jpeg']
  if (!allowed_file_types.includes(fileType)) {
    throw Error(`File type not allowed. Allowed types are: ${allowed_file_types.join(', ')}.`)
  }

  const r2 = new AwsClient({
    accessKeyId: config.r2.accessKey,
    secretAccessKey: config.r2.secretKey
  })

  const fileName = `${nanoid(6)}.${fileType.split('/')[1]}`

  const url =
    `https://${config.r2.bucketName}.${config.r2.accountId}.r2.cloudflarestorage.com` +
    '/profile' +
    `/${fileName}` +
    '?X-Amz-Expires=3600'

  const signed = await r2.sign(url, {
    aws: { signQuery: true },
    headers: {
      'Content-Type': fileType,
      'Content-Length': `${fileSize}`
    },
    method: 'PUT'
  })

  return { fileName, url: signed.url }
}

Hmm unless I'm misunderstanding thissue, I cannot repro this. I've got a custom domain attached to a public bucket with r2.dev disallowed, and yet I can access my bucket publicly. Are you accidentally visiting the r2.dev URL?

Connecting customer domain example.com to bucket. -> visit example.com -> not allowed to see bucket

Are you expecting

/

to serve

/index.html

?

I was expecting a folder tree

R2 doesn't do that at the moment

If the asset you try to get doesn't exist, you'll see that page

Thank you for helping

Hello, I've just setup R2 service with custom domain, it is working perfectly fine, I just want to replace cloudflare's index page with my own. I am getting 404 error when I try to access domain.

i don't think that's possible yet. just create a worker for that. if get object not found, return 404 w/ html

r2 team, I'm noticing the following

get: Client Disconnect (10054)

on my workers log, is it related with R2? i have r2 get + put ops, but idk what that error message relates to.

hi folks, i have a question: if there are way to manage object expiration for R2? I checked the docs but did not found it. Like AWS S3 have management (with different object transformations), but only "delete in 2 days" or "delete in 3 days"?

It's not currently supported unfortunately

well at least it could be done in theory via cron which will list object and simply wipe them. But "from the box" could be good. personally: i like CF and use it almost 10 years 🙂 it's nice to see how CF is developping
