Has anyone come across this error when creating a custom instance? If I set the values of the custom instance to match a named instance, it works fine, but say I change vcpu to 1, this will happen?

Do you have the right entitlements for 1 vCPU? I don’t believe that’s available on the general paid plan.

Believe the account is on enterprise which assuming that should allow more vCPU allocation?

hmm, wondering if egress from containers -> its associated DO is billed?

pandalambda2•8/13/25, 2:35 AM

I think it must be otherwise you just proxy everything and get free unlimited/egress?

pandalambda2•8/13/25, 2:35 AM

but then that does raise the question what about communication with KV, D1, queues, R2 etc.. ?

can one tail cloudflare container stdout/logs via wrangler do we need to do the click next dance on the web admin ui?

It looks like this was a change where the port in the URL (i.e 8787 for local Wrangler dev) started being used

kian•8/13/25, 9:44 PM

You should be able to use .containerFetch(request, <port>).containerFetch(request, <port>) or .fetch(switchPort(request, <port>)).fetch(switchPort(request, <port>))

make sure you have the latest wrangler version, I had some weird permission errors on older versions

gruntlord6•8/13/25, 10:23 PM

thats kind of what I was wondering, and yea I am assuing it is or else you would just use the DO as a proxy

gruntlord is right - that Wrangler version is older than when the Containers scope was added to the login command

henri•8/14/25, 2:16 AM

I'm having the same issue as described here @Mike Nomitch any news on the geographic
I just pushed a new version to my container, and it no longer starts. There are no logs available since the deployment, and requests to the container simply time out.

What does the instance list look like for you in the dashboard?

Kkian What does the instance list look like for you in the dashboard?

henri•8/14/25, 3:11 AM

I can see that there are two versions, it's running but I can't see any logs

kian•8/14/25, 3:11 AM

What are their IDs (and which is which)?

henri•8/14/25, 3:12 AM

there is only one instance, which has two versions, but the instante id should be the same, right?
anyway, here it is: 84d70fb446c123ff301da66929ea1aa10e9a2211820d7b760e03ac1efcb977ab

I would love that to be the case so I hope I am wrong, I think paying egress from cloudflare to cloudflare is insane

kian•8/14/25, 2:17 PM

The team couldn't find any issues in the logs & it seemed to be healthy to them - are you still having the issue?

CD_CNTNew•8/15/25, 8:50 AM

Anyone come across containers become harder and harder to be active after several times of successful startup&stop, mostly with "no container instance" or "not listening on TCP" errors? On the dashboard, the logs show containers seem like never get requests from workers to wake up.

I haven't. I have an image processing container so that I can use sharp to batch convert images and store them in R2. I start it up frequently, upload more images, start it up again to do those etc.

what is you use case where this occurs?

gruntlord6•8/15/25, 11:52 PM

is there a way to see billable container usage?

CD_CNTNew•8/16/25, 3:15 AM

Just normal http backend in the containers, stateless even. Thought it's a simple usecase for testing the containers on cloudflare, but never thought what happened like this. I guess containers never got requests from workers or durable objects bound with them, sort of bugs?

gruntlord6•8/16/25, 3:16 AM

sorry I'm not really following, you have a web service running from the container directly and it never responds?

CD_CNTNew•8/16/25, 3:17 AM

actually never start up I think. Once start up successfully, they can respond quite well

gruntlord6•8/16/25, 3:18 AM

it should start as soon as you run the attached durable object

CD_CNTNew•8/16/25, 3:19 AM

yes, at the begining just deployed, they worked well but after several times start and stop, they appeared harder to wake again

gruntlord6•8/16/25, 3:20 AM

no idea, I've even had 10 instances running for the same job without any issues starting them and stopping them

CD_CNTNew•8/16/25, 3:21 AM

how about the sleepafter of your containers?

gruntlord6•8/16/25, 3:21 AM

although I always communicate with the durable objects associated with the container

gruntlord6•8/16/25, 3:21 AM

its set to 30s so I can keep them warm, I was worried the image conversion might take longer then 10s and I don't want it shutting down mid conversion

gruntlord6•8/16/25, 3:22 AM

but I also don't want them running longer then i need them

CD_CNTNew•8/16/25, 3:22 AM

I set it to 3m

CCD_CNTNew I set it to 3m

gruntlord6•8/16/25, 3:22 AM

that would mean that unless you end the task properly it says alive for 3m doing nothing

gruntlord6•8/16/25, 3:23 AM

well assuming it finishes the task in that frame, for example when I was using one instance it would keep running as long as I kept it queued with tasks

CD_CNTNew•8/16/25, 3:23 AM

just want them to run as long as I need, coz after they turned inactive, hard to wake them up

gruntlord6•8/16/25, 3:24 AM

theres a 3 second cold start, is that accounted for when you are waking them up?

gruntlord6•8/16/25, 3:24 AM

or do they just fail to start at all

CD_CNTNew•8/16/25, 3:25 AM

fail to start

gruntlord6•8/16/25, 3:25 AM

is it something in your code then?

CD_CNTNew•8/16/25, 3:28 AM

I tested the image locally, worked well, and on cloudflare they could work after just deployed, so I think the codes are ok

CD_CNTNew•8/16/25, 3:32 AM

on the worker side, I've got the messages like no container instance or no tcp port listening, on the container side, no requests arrived so that I think no chance for my codes to run

Hey all! I tried to find sandbox instance limits but there is no clear answer in the docs anywhere - am I missing anything? the reference to container limits is a bit confusing. Does it mean that max sanbox instance == max container instance for the user account? (or project)?

Appreciate the reply

gruntlord6•8/17/25, 6:00 PM

sanbox?

gruntlord6•8/17/25, 6:00 PM

do you mean the max instances you define?

Alexander•8/17/25, 8:36 PM

yep referring to @Cloudflare/sandboxes

aren't max instances referring to max container instances? or 1 sanbox == 1 container instance used?

Has anyone come across this error when creating a custom instance? If I set the values of the custom
