Does uploading to R2 count as egress?

GGhost Furry Does uploading to R2 count as egress?

Hello, I’m Allie!•7/27/25, 5:30 PM

If you are doing so from a cloud that charges egress, yes

Hello, I’m Allie!•7/27/25, 5:30 PM

We won’t bill you for it, but they might

Ghost FurryOP•7/27/25, 5:32 PM

From where i will bet object is different things

Take a example

I got the object file in container

Then upload that to R2 like we do using workers by binding

Then it will charge for uploading to R2 ?

Hello, I’m Allie!•7/27/25, 5:37 PM

You will be charged a single Class A operation(assuming you don’t use a Mulitpart Upload). R2 doesn’t bill by the gigabyte for uploads, just for storage and Infrequent Access Retrieval

Yeah that i get but talking about egress charges in Cloudflare container

So putting file in r2 doesn't count as leaving out the network

Hello, I’m Allie!•7/27/25, 5:39 PM

Sorry about that, I completely missed which channel we are in. R2 does not bill for Ingress, but Containers does bill requests to R2 for egress

Would containerFetch be the reason why my container takes a long time between requests to many routes? Making many containers - one for each pathname - makes things fast but every weird, that’s one container per pathname

Marcell•7/29/25, 7:44 PM

Is it possible to route request to a container without javascript fetch?

King Kazu•7/30/25, 4:07 AM

why is my container stuck as "degraded"? I can't even debug why the container is not starting???

King Kazu•7/30/25, 4:50 AM

would love to see some visibility into the container provisioning process so I could at least see why its erroring?

King Kazu•7/30/25, 5:27 AM

so I think my issue had to due with my issue being too large, but there was never any warnings / errors from wrangler

Marcell•7/30/25, 7:24 AM

Is there any plan to run containers without workers script? It would be nice to deploy containers without requiring to write the glue code that slows down the requests anyway.

Alexander•7/30/25, 7:59 AM

Hey

If you accept feature requests here - Windows support for containers local dev would be great! I tried running through WSL but the install / startup time was so slow I couldn't launch the dev server

mattderron•7/30/25, 8:26 PM

Hi Mike - wanted to follow up on the Cold Start PR - did that get rolled out already? I've notice some pretty long cold starts (10s+ in some cases), and I'm sure there are things I can do to improve it code-wise. But was wondering if that PR was already out so I know what baseline I'm starting from to try to improve.

PPonjimon How do you pass build args to the container image when building it?

henri•7/31/25, 12:27 AM

Has anyone figured out how to pass build args to the container image during the build? I need to access an environment variable at build time, but I haven’t found a way to pass --build-arg--build-args or something similar when building a Dockerfile

kian•7/31/25, 12:32 AM

It sounds like you want image_varsimage_vars in the Wrangler config under containerscontainers

henri•7/31/25, 5:28 AM

I see... I was hoping I would be able to read it using ARGARG or something like that

Codename_404•7/31/25, 8:39 AM

You are billed for your usage of both Workers and Durable Objects.

Does this mean, i will be charged for the entire execution time for all 3? DO, container and worker?

Yash•7/31/25, 9:01 AM

Does it support a minimum instance setting, so that at least one instance stays active to avoid delays caused by container cold starts?

kian•7/31/25, 12:25 PM

Can’t you use ENV?

Julian•8/1/25, 12:38 PM

After reducing the number of max_instances i get the Error "The maximum amount of containers allowed to run in the Durable Object namespace is the same to the amount of running Durable Object Containers, we won't be able to assign an instance to this Durable Object Container" when trying to start a container. how can i fix that

John Spurlock•8/1/25, 2:01 PM

Yes, the DO and container based on actual time, and the entry worker based on cpu time only (which will be much less if it is just calling a DO and waiting for IO)

gruntlord6•8/1/25, 2:52 PM

what if it was proxied through the durable object? It's very odd that egress is charged when its not leaving cloudflare, especially since thats not how any other cloudflare compute works

Codename_404•8/1/25, 3:45 PM

So it will also charge for DO IO, as well as CPU time?
of so it should be very expensive for large project, right?

dustiiin•8/1/25, 5:26 PM

Hello, where do i see billable usage for containers?

Ddustiiin Hello, where do i see billable usage for containers?

John Spurlock•8/1/25, 5:33 PM

hmm, good question - it's not currently on the account-level billable usage page https://dash.cloudflare.com/<account-id>/billing/billable-usagehttps://dash.cloudflare.com/<account-id>/billing/billable-usage so the best thing it seems would be to use the GraphQL analytics api

captainclaw•8/1/25, 5:40 PM

The 0.5 vcpu is killing me. The highest tier should not have cpu contention issues.

I have workloads that I cannot reason about, in terms of when or if they’ll complete.

I’m trying to run an agent and it basically just stalls a long time. Anyways, I put them in fly.io for now, but I’d really love to stay within the Cloudflare ecosystem

dustiiin•8/2/25, 8:37 PM

Hello i configured a sleepAfter of 2 minutes, but there is a container running for over 20 hours now and the last interaction is 50 minutes old but it keeps staying up
is this normal or a bug and how do i stop it?

userzach•8/3/25, 2:59 AM

Hi! I participated in Private Beta. I might be affected by https://github.com/cloudflare/workers-sdk/issues/9898.

My specific error is: "The image registry does not exist""The image registry does not exist"

Hey looking for help... the instance is running now for over 40 hours without any interactions in it. It seems that the sleepAfter is not triggering
In the meanwhile there is a second instance that is not stopping
