Hello! Are there any examples of github actions for containers deployment? My action works intermittently, fails often with auth permission:
[ERROR] A request to the Cloudflare API (/zones/.../workers/routes) failed.

Authentication error [code: 10000]

It looks like you are authenticating Wrangler via a custom API token set in an environment variable.
Please ensure it has the correct permissions for this operation.

Are you providing it an API token? Shot in the dark, but if you are using the default "edit cloudflare workers" template, it doesn't seem to include containers permissions by default, might be worth trying to add that permission and see if it helps

Has anyone had success with containers on ARM based macs? getting container errors on both base OS and in a devcontainer on mac. Everything seems to be configured correctly but can't get it to fetch properly. Even the cloudflare examples don't seem to be working. Haven't tested on an x86 machine yet

So... I've managed to get some interesting proof-of-concept stuff going with containers. But to make them really useful I need to talk to data somewhere...

can I bind D1 somehow? do I need to talk back to the worker for D1? is the standard approach for this a websocket?
- what are the plans for mounting R2 like was discussed on the video?
- what about hyperdrive?
- I have some workloads where even with hyperdrive I can't imagine wanting to be out of the same region as my DB. and right now my containers end up on another continent.

Can we use the Containers beta to run the Browser Rendering feature at a higher memory?
Or is the dockerfile a must and must I try to run e.g. Chromium via Docker?

sampotter•7/9/25, 10:10 AM

Anybody elses containers being consistently being evicted after approx 2 minutes? I'm starting up a container manually using the startstart method so that I can provide a JOB_IDJOB_ID environment variable to the container. The job starts up and begins processing for roughly 2 minutes before dying? Is this normal? Btw I'm setting the sleepAftersleepAfter option to 24h24h

Hello, does anybody see why I'm getting the following 404?

snehendu•7/10/25, 5:26 PM

Hey everyone, does anyone know how to do programmatic deployment to cloudflare?

In my usecase, users would want to spin up a docker container from a docker image. But the thing is I want to do this programmatically as I will have the container code saved in R2

There will be multiple containers that will spin up from a single image and we need to take care of how to handle the deployment

Kraus•7/10/25, 9:18 PM

I am setting instance type to standard but the actual containers are still getting provisioned to 256mb of memory. How can I fix this?

Beny•7/13/25, 8:21 AM

We are using the websocket method. It works pretty well.
You can also run a local worker inside the container with remote bindings to access things like R2 and D1. Hyperdrive isn't supported with remote bindings yet but is being worked on

flof.fly•7/13/25, 8:38 AM

Hey, I'm working Locally with Worker invoking a Workflow invoking a Container.

It seems to me that Workflows are Docker Containers when executed locally, and Container is also up&running in localhost:8080 (i can reach it using postman i.e)

But seems that the Workflow's container is unable to see the Container's container.

I get the following error in localhost:

✘ [ERROR] Error checking if container is ready: connect(): Connection refused: container port not found. Make sure you exposed the port in your container definition.

✘ [ERROR] Error checking if container is ready: The operation was aborted

I tried changing hostname to 0.0.0.0:8080 but didn't change much.

Any help? Would love to share my wrangler config file.

This only applies in localhost, deployed works as expected.

bomboclat•7/14/25, 9:16 AM

Have you tried removing the extra port? just debugging by reducing the complexity of exposing two ports

Eelco•7/14/25, 9:42 AM

Facing the same connection issues locally on macos.

The container is mapped to 550XX -> 8080 and the worker says it can't connect to 8080. The ephemeral port mapping doesnt seem to work correctly. Since the worker can spin up multiple containers it shouldn't try to connect to 8080 directly but the mapped 550XX port.

Eelco•7/14/25, 10:01 AM

Downgrading to "@cloudflare/containers": "0.0.19", from 0.0.22 fixed it.

Eelco•7/14/25, 10:07 AM

I recon this is the issue.

https://github.com/cloudflare/containers/commit/0611bc7dcb0653b0c90c3fa9d0d6a00d31d0ae5d#diff-29f6935de7d89eec5929ebe8d3fb298265b320961523b05695398f0bc4ae729bR746

The request comes from localhost:8787. with this change instead of using the default port it will use the port of the original request 8787 and the container request fails

azeii•7/14/25, 12:34 PM

Does data transfer from Cloudflare Containers directly to Cloudflare R2 incur egress fees, or are requests "within Cloudflare" exempted from egress fees? https://developers.cloudflare.com/containers/pricing/#network-egress

Pricing

Containers are billed for every 10ms that they are actively running at the following rates, with included monthly usage as part of the $5 USD per month Workers Paid plan:

@Mike Nomitch | Workers PM any news on the geographic placement issue you mentioned a couple of weeks back? I'm based in SF and getting almost exlusively Asia containers

Mike Nomitch•7/15/25, 12:24 AM

I tend to just do something similar to the main template (linked to from the UI), and then modify from there

Mike Nomitch•7/15/25, 12:24 AM

What’s the specific error?

Mike Nomitch•7/15/25, 12:25 AM

And sorry just went mobile so won’t be able to go in depth yet.

I’d share:

what environment is the issue happening in?
could it be some error bringing down the instance? (We’re working on exposing OOM messages better now)
setting right port in code and using Container class? Not Durable Object directly?
