Hello, I contacted earlier about whether if Cloudflare Containers supports nested virtualization in their Container infrasturcture and need the functionality for allowing using microVMs inside of the container.

Is there a way of customizing how the container itself exposes devices such as /dev/kvm?

Hi, I’m running into an issue with my Worker + Containers setup. In my wrangler.toml, I’ve defined both the container and the durable object binding like this:

[[env.production.containers]]
max_instances = 10
class_name = "ForumFullscanContainer"
image = "./containers/forum-fullscan/ForumFullscanDockerfile.dockerfile"

[[env.production.durable_objects.bindings]]
name = "FORUM_FULLSCAN_CONTAINER"
class_name = "ForumFullscanContainer"

[[env.production.containers]]
max_instances = 10
class_name = "ForumFullscanContainer"
image = "./containers/forum-fullscan/ForumFullscanDockerfile.dockerfile"

[[env.production.durable_objects.bindings]]
name = "FORUM_FULLSCAN_CONTAINER"
class_name = "ForumFullscanContainer"

[[env.production.containers]]
max_instances = 10
class_name = "ForumFullscanContainer"
image = "./containers/forum-fullscan/ForumFullscanDockerfile.dockerfile"

[[env.production.durable_objects.bindings]]
name = "FORUM_FULLSCAN_CONTAINER"
class_name = "ForumFullscanContainer"

[[env.production.containers]]
max_instances = 10
class_name = "ForumFullscanContainer"
image = "./containers/forum-fullscan/ForumFullscanDockerfile.dockerfile"

[[env.production.durable_objects.bindings]]
name = "FORUM_FULLSCAN_CONTAINER"
class_name = "ForumFullscanContainer"

I deployed locally yesterday using npx wrangler deploy --env=production, and it was working fine. Today, after another deployment via our GitHub Action, it stopped working. The wrangler.toml hasn’t changed. and the Durable Object migration has also been applied.
The error I’m seeing in the Worker logs is:
"Container is not enabled for this durable object class. Have you correctly setup your wrangler.toml?"
Could someone help me understand why this might be happening?

J

Hey y'all! I have been trying to get a very simple worker and container running locally, and when the container is created, it gets a really high

HOST_PORT

HOST_PORT

HOST_PORT

HOST_PORT I'm using rancher desktop. And my docker file builds correctly and is usable on its own. But when running

wrangler dev

wrangler dev

then hitting the endpoint I see the container start up in rancher, but the

HOST_PORT

HOST_PORT

HOST_PORT

HOST_PORT is not what I would expect it to be. I'm assuming that's why I can't connect when using the local worker. I really appreciate any insight y'all may have.

rust-task-container-staging already exists and can be viewed from the dashboard btw.

EDIT: Ok found a way to reproduce this. wrangler deploy will always fail the very first time when there is no image and generate an image tagged registry.cloudflare.com. If I keep the image and run deploy, it will succeed with

Image already exists remotely, skipping push

Image already exists remotely, skipping push

Image already exists remotely, skipping push. If you delete the image from Docker Desktop and run deploy you will run into the same error. This explains why it always fails in ci.

Maurice•8/22/25, 7:10 AM

When working inside containers there is no access to worker bindings, so when using a product like queues, limited to pushing by sdk / http. This works, however, when working on development (wrangler dev), the simulated queues are in the run time and not exposed to http, so the only option is to debug in production. Is there a better way to get around this? I'm not sure this is the best place to report this, but I figured someone would pick it up.

Found out that wrangler deploy does not replace the image with the new image ever. The image shown on cloudflare containers dashboard was much older version regardless of how many new image I deploy. Obviously, the first failure uploads to the repository but fails to update the image to use the newst tag. And the second run just skips pushing the new image and treats it as already existing. Only way to get new image up is deleting the container from the dashboard and redeploying, which is not ideal.

Experiencing a new issue and wondering if anyone has experienced it too. I have worker A conencting to worker B using a service binding (with

fetch

fetch

), and worker B uses a container. It used to work (last tested about a week ago), but as of yesterday it doesn't seem to work at all. Worker A makes the fetch request and it just gets stuck.
1. Running both locally with wrangler - everything works as expected (I can see A fetching from B locally).
2. Making a regular request to B works (when I switch to

fetch("https://worker-b.account.workers.dev/process/video"

fetch("https://worker-b.account.workers.dev/process/video"

fetch("https://worker-b.account.workers.dev/process/video"
