Is it possible to set an auto-delete timer for the uploaded images in the R2 storage, instead of doing it on my own after a while? (Not all images though, certain ones that I upload)

Z

zegevlier•1/18/24, 2:05 PM

This is the closest thing to that: https://developers.cloudflare.com/r2/buckets/object-lifecycles/

Z

zegevlier•1/18/24, 2:05 PM

Otherwise, you could set up a Durable Object on workers with an alarm to delete it

D

devrunner•1/18/24, 2:10 PM

Hmm, can I create a separate bucket under the same custom domain then and maybe add the object-lifecycles there?

D

Ah, I've just checked it doesn't seem it's possible, that's alright I'll create another subdoman.

Do I need to create a worker if to give anyone access to my bucket file (readonly) on internet or is there something already built by default (like a cdn or smth). I'm a little confused

A

Alaanor•1/18/24, 4:50 PM

Public buckets are available on a regular HTTP endpoint. By default, there is no authorization or access controls associated with a public bucket. Anyone with a public bucket URL can access an object in that public bucket

Seem like it can by default, I just need to figure what url that would be

is there a rust package to use r2 and kv without wrangler?

U

Unsmart•1/18/24, 10:06 PM

R2 can be used with an s3 compatable sdk. KV you either need to go through a cloudflare worker or the rest api.

U

Unsmart•1/18/24, 10:07 PM

and the rest api is not recommended

J

is there a reason for it being so tied in with workers? and not recommended to use the rest api?

hello - im trying to get started with simply showing a picture that i have in my bucket (ive been able to do it with another site but all the images in the public were public which im trying to avoid this time round)

im using cloudflare pages and linked to a github repository
i have made a html file to show an image of a panda and the html links to a javascript.js

the panda image is in my bucket - ive made the link between the page and the bucket - the bucket variable is called PANDA_BUCKET

async function getPandaImage(context) {
    try {
        const obj = await context.env.PANDA_BUCKET.get('baby panda.JPEG');
        
        if (obj === null) {
            console.log('Image not found');
            return new Response('Not found', { status: 404 });
        }

        console.log('Image found:', obj);

        return new Response(obj.body);
    } catch (error) {
        console.error('Error fetching Panda image:', error);
        return new Response('Internal Server Error', { status: 500 });
    }
}

async function getPandaImage(context) {
    try {
        const obj = await context.env.PANDA_BUCKET.get('baby panda.JPEG');
        
        if (obj === null) {
            console.log('Image not found');
            return new Response('Not found', { status: 404 });
        }

        console.log('Image found:', obj);

        return new Response(obj.body);
    } catch (error) {
        console.error('Error fetching Panda image:', error);
        return new Response('Internal Server Error', { status: 500 });
    }
}

async function getPandaImage(context) {
    try {
        const obj = await context.env.PANDA_BUCKET.get('baby panda.JPEG');

Big Al•1/19/24, 4:38 PM

I am using AWS SDK V3 to upload/fetch files from R2. I am testing out the CreateBucketCommand and the ListBucketsCommand.
I am receiving these responses from both methods but no data:
response1= {
'$metadata': {
httpStatusCode: 200,
requestId: undefined,
extendedRequestId: undefined,
cfId: undefined,
attempts: 1,
totalRetryDelay: 0
}
}

I also added 'forcePathStyle: true' to the config which fixed the previous error of 'NoSuchBucket' when trying to create a bucket,
not sure how or why I had to do that. I've also tested this with AWS S3 and it creates the buckets and lists the buckets with no problems.

The code:

const options = {
  region: 'us-east-1',
  accessKeyId: process.env.ACCESS_KEY_ID!,
  secretAccessKey: process.env.SECRET_ACCESS_KEY!,

  maxFileSize: 10,
  validMimeType: [],
  format: 'url',
  urlExpiration: 10,
  path: path.join(__dirname, 'downloads')
};

describe('s3Controller', () => {
  it('should create a bucket', async () => {
    const input = {
      Bucket: options.bucketName,
    };

    try {
      const command = new CreateBucketCommand(input);
      const response = await client.send(command);
      console.log('response1=', response);

    } catch(err) {
      console.log('err=', err);
    }
    expect(response).toEqual({});
  });
});

describe('s3Controller', () => {
  it('should list buckets', async () => {

    try {
      const command = new ListBucketsCommand('');
      const response = await client.send(command);

Presigning does not involve the server, it doesn’t cost anything

Generating a presigned url doesnt ever touch cloudflare. But when you actually go to the presigned url it will do whatever operation you told it and count

K

Karew•1/19/24, 7:27 PM

You asked about presigning. Your local S3 client presigns an unsent request. It doesn’t cost anything to presign. It only costs an operation if someone actually makes the request

E

And then the type of operation charged depends on the type of request you created and used

I just had a somewhat, um, weird experience with adding an R2 subscription. When I looked at my Billing Subscriptions, R2 was enabled. But when I attempted to configure it, all I got was the R2 intro funnel page with a big blue button asking me if wanted to add it to my subscriptions. Then I went to cancel the subscription. Only once it was canceled could I then access the actual R2 control panel. But it seems like I can't resubscribe to R2 now. Who should I be asking for help to be allowed to resubscribe to R2? TIA.
