I'm assuming you mean accessing the bucket via an r2 binding, and not literally fetching it via a worker
Cthat doesn't sound related to the command, why can't you make it public? Do you get an error? Do you mean adding a custom domain, or enabling the r2.dev subdomain?
AYup, I was referring to the example on the docs - https://developers.cloudflare.com/r2/examples/cache-api/
My usecase is quite simple, I have a few public buckets which host static assets for websites, e.g images, pdfs, audio etc.
I was looking into how to get the most performance out of R2 and any custom settings I need to enable to make this happen. Hence the curiosity about the cache API

ASo, if I understood you correctly, given I'm just serving static assets publicly, proxying requests to R2 via workers + cache api (as in the example) won't get me anything extra over simply relying on cloudflare's cdn cache?
CIf all the assets are public, just R2 Custom Domain & A Cache Rule to force caching (or upload the objects with a Cache-Control header). You won't be charged for cached hits, and you wouldn't be paying for worker invocations
Cthe cache api would just be accessing the normal cdn cache as well
technically the cache api is just local colo (cloudflare location) cache, where the normal cloudflare cdn cache could be tiered cache or cache reserve, but R2 Custom Domains are special and don't support either

Agotcha, thanks for clarifying 
Awould it use tiered cache if I connected a custom domain to the r2 bucket?
Cno
CCache API in Workers doesn't support it at all, and R2 Custom Domains specifically don't either
Si'm added custom domain, but not work
i'm actived r2.dev, after worker..
i'm actived r2.dev, after worker..
Svery strange.. but ok
CYour custom domain doesn't work? What error do you get?
Sbucket dont public
Sit worked after enabling R2.dev subdomain
Sbut it's weird having to do that
Kr2.dev isn't needed for custom domains, they're separate. What error do you see when you try to add the custom domain? Can you take a screenshot?
CHi, could someone help me with r2 (I'm using the aws sdk in go)
Something strange happens because when I run it on my localhost it works fine, the problem arises when I try to run it on a docker image

Cis is in production? can check your hostname domain in production. Last time my domain was
1.2.0.chientrm.com and it failed. Then I change to 1_2_0.chientrm.com and it works.
Ar2.cloudflarestorage.com/noti is this
Cnoti.97b809ded26d1.r2.cloudflarestorage.comCthis's not gonna work.

ZHello, I have one more question, the "CDN" cited in the article is included the use of cache for files that are not cached by default? or is it just for the reverse proxy
KIf you use R2 you can cache any file type
CHi everyone, someone knows if there are plans to have some "intelligent tiering" like in S3 for R2?
OHello.

AHello!
When I moved to r2, I uploaded all my files through rclone, and now I upload new ones through the s3 api.
For some reason, the first downloaded pictures open in my browser, and the second ones are downloaded and I am getting the message "Your connection to this site is not secure". They have some kind of different type of access or something like that? I don’t understand how they differ in one bucket if only the download method was different.

CUpdate: I solved it by adding the volume
/etc/sslKAre you using a pubic URL for both?
AI use access through a connected custom domain, it is the same for all photos
KAre you able to share any example links?
KThose both work for me, so my guess is you just need to purge your Cloudflare cache
KBut also: You did not upload this file with the correct
https://img.poisondrop.ru/upload/item_sku/img/desktop/125685AEyXoBOTNIUu.jpeg
Content-Typeapplication/octet-stream which is the defaulthttps://img.poisondrop.ru/upload/item_sku/img/desktop/125685AEyXoBOTNIUu.jpeg
AThanks a lot! I will investigate the issue
CCaused by: java.lang.Throwable: Acquire operation took longer than the configured maximum time. This indicates that a request cannot get a connection from the pool within the specified maximum time. This can be due to high request rate.
Consider taking any of the following actions to mitigate the issue: increase max connections, increase acquire timeout, or slowing the request rate.
Increasing the max connections can increase client throughput (unless the network interface is already fully utilized), but can eventually start to hit operation system limitations on the number of file descriptors used by the process. If you already are fully utilizing your network interface or cannot further increase your connection count, increasing the acquire timeout gives extra time for requests to acquire a connection before timing out. If the connections doesn't free up, the subsequent requests will still timeout.
If the above mechanisms are not able to fix the issue, try smoothing out your requests so that large traffic bursts cannot overload the client, being more efficient with the number of times you need to call AWS, or by increasing the number of hosts sending requests.
its possible that fix?

SWe’re looking at storage tiers in general currently, but the “intelligent” bit is probably going to take a while to land.
CClear!! Thanks for letting me know 
JI need some help -- I'm trying to generate a presigned upload URL with R2 and I keep getting this error:
"The request signature we calculated does not match the signature you provided. Check your secret access key and signing method."
My go code is as follows:
func CreatePreSignedUploadURLR2() (string, error) {
iSess, err := session.NewSession(cloudflareR2Config)
if err != nil {
return "", err
}
sess := session.Must(iSess, nil)
svc := s3.New(sess)
r, := svc.PutObjectRequest(&s3.PutObjectInput{
ACL: aws.String("public-read"),
Bucket: aws.String("bucket-name"),
Key: aws.String("file.png"),
})
url, err := r.Presign(10 * time.Hour)
return url, err
}
I have similar code where I use the same R2 config and upload files like this and it works fine:
uploader := s3manager.NewUploader(sess)
, err = uploader.Upload(&s3manager.UploadInput{
ACL: aws.String("public-read"),
Bucket: bucket,
Key: key,
Body: bytes.NewReader(file),
ContentType: aws.String(ContentType),
})
Any ideas what I could be doing wrong?
This is what the pre-signed URL looks like:

JThis is what the token permission looks like as well...so it should work for this
KYou add an R2 subdomain in the settings for your bucket
SYou need to link to the file, for example, ABC.xyz.com/example.png
