Those env vars sre different. But i think getContainer with a naming pattern could be the say to go

darkpool•10/20/25, 7:44 PM

is there anything we can do with wrangler's dev registry to bypass dockerizing the container each time we want to run it locally? I am new to docker and containerization in general so not sure if I'm missing something key but waiting for container to build during dev is a slog in a monorepo. When I'm just working on the container I can just run it directly with tsx but Id like a way to just tell the CF container class to look for a local instance running (simmilar to how wrangler finds other workers exposing RPC entrypoints) EDIT: just pushing and pulling from registry is what I needed to do

I got around to testing download speed from R2 into a container. A bit disappointed, roughly the same speed as just

wget

wget

wget

wget on from my home network. :sad_frog: (using a public R2 bucket for the test)

Hi everyone!

I upgraded to Workers Paid plan ($5/month) 13+ hours ago but Containers are still not enabled for my Durable Object.

Account: Hello@bechallenge.io
Worker: vibesdk-production.cognicraft.workers.dev
Error: "Container is not enabled for this durable object class"

Workers Paid active (payment confirmed: $5 USD/month)

@cloudflare/sandbox 0.1.3 installed

Redeployed multiple times

Dashboard shows "You have no Containers"

Can someone help enable Containers for my account?

"Container is not enabled for this durable object class" is likely an accurate error - what's your Wrangler config?

N

nicoritschel•10/22/25, 2:45 PM

I seem to have inconsistency in the state of my container. If I click that instance marked stopped it seems nothing is running as per metrics. I expect that something is running currently as it was triggered from a workflow.

N

nicoritschel•10/22/25, 2:46 PM

The meter also shows 1 live instance; maybe it's not booting?

N

nicoritschel•10/22/25, 2:51 PM

Ah was just intermittent, redeploying cycled it

K

kianOP•10/22/25, 2:54 PM

There's a little bug we're currently fixing where live instances represents your Durable Object that has access to the Container being active even if your Container itself isn't (i.e DOs hang around for 30s after their last request or you were doing non-Containers API calls)

K

kianOP•10/22/25, 2:54 PM

That's just a dash / health reporting UI quirk, your Container shouldn't be running & we're not billing you for it.

Thibault•10/22/25, 9:03 PM

What would be the best way to keep a container up and running 24/7 ?

nicoritschel•10/22/25, 10:13 PM

You could probably use an alarm on the attached durable object and keep waking it

There is no container instance that can be provided to this Durable Object, try again later - we are also getting this error a lot I am adding the config below.

image = "./Dockerfile"
max_instances = 25
instance_type = "standard-4"

image = "./Dockerfile"
max_instances = 25
instance_type = "standard-4"

image = "./Dockerfile"
max_instances = 25
instance_type = "standard-4"

image = "./Dockerfile"
max_instances = 25
instance_type = "standard-4"

Could you hint us that where are we going wrong for these two places?

Decrease max instances to stay under the vcpu limit. These limits will be increased over time as the platform matures and kinks are worked out

Hi. I have been tricked by an ad/review on the website www.theresanaiforthat.com into purchasing a year subscription of www.v93ai . The former Site advertised this A I Tool specifically as an "Illegal" Video Generator , meaning basically that it was promoted as an Agent which can be used to generate Adult or Explicit Content. For $82.00 I discovered instantly that it did not! I've emailed the company outlining my dissatisfaction but
it hasn't got through, it just returned to my email. So I'm here asking you, what is my next step & how do I go about getting a refund from these people? I'd appreciate some advice.
Many thanks.

since ~2200-0000UTC last night, still ongoing, we've started seeing a whole bunch of CF internal errors thrown by our containers when trying to communicate with DOs

e.g.

internal error; reference = 0sp6nv1fqj06ub0q9b0qbfjq

internal error; reference = 0sp6nv1fqj06ub0q9b0qbfjq

internal error; reference = 0sp6nv1fqj06ub0q9b0qbfjq

Yes & no - your DO doesn’t necessarily have to be around but currently does influence the lifetime of your Container, I.E sleepAfter in the Containers library starts after DO inactivity

We’re working on moving lifecycles to more Containers APIs so the DO doesn’t have to be around to do any of that though

The allocated resources of the instance type, not dependent on what the application actually uses within the container, the only variability is the egress your application uses.
