Curious how much something like vaultwarden would cost to run on here with a few users and devices phoning home (basically it never sleeping)

hello, can we hide these logs when starting a container?

Hi, I've got some issues when starting my Go service. I always get this error message:
Failed to start container: The container is not running, consider calling start()Failed to start container: The container is not running, consider calling start()

And I can't find anything regarding this in the logs. Does someone has an idea how to resolve this? My current Dockerfile is working locally and in my k8s cluster, so I think it should be related to cloudflare containers

when using startAndWaitForPorts, does 10000 requests to an unstarted container wait for the one issued start given the container has one name?

Nick•11/4/25, 2:19 PM

Does anyone know if there's a limit to subrequests insidea container?

NNick Does anyone know if there's a limit to subrequests insidea container?

Isaac McFadyenOP•11/4/25, 3:28 PM

There shouldn't be from the container itself (the attached DO is subject to the limit still).

Isaac McFadyenOP•11/4/25, 3:28 PM

A container has it's own networking and doesn't rely on the Workers HTTP stack so you can effectively do whatever you want (within reason)

Maulik Tyagi•11/5/25, 10:34 AM

yes, you can

Yeah thought I would give cloudflare a try, since all of my applications are already running in k8s, but this platform is totally bad. I've set everything up the right way, set my env variables etc. and my applications won't start. Idk why they won't, because you can't even debug it the right way, even with enabled observability

J1mb0•11/5/25, 6:12 PM

Indeed it is and I think it comes from:

   await container.startAndWaitForPorts({
          ports: [8080],
                
          startOptions: {
            enableInternet: true,
            ...c.env, 
          },
        });

   await container.startAndWaitForPorts({
          ports: [8080],
                
          startOptions: {
            enableInternet: true,
            ...c.env, 
          },
        });

`

But If I remove this line, I'm getting the following error:

Failed to start container: The container is not running, consider calling start()

Failed to start container: The container is not running, consider calling start()

J1mb0•11/5/25, 6:14 PM

I only see this error in my logs and nothing else. And this application is already running in a k8s cluster without any issues

gruntlord6•11/5/25, 6:50 PM

I don't use hono or most of your stack so I'm not really going to be much help there.

For starting and stopping the containers, I'd use one of the examples in the documentation as a reference. Right now I have a simple concept express app for backing up durable objects to r2 that gets started by a worker calling the containers durable object. My code was made by referencing one of the examples

Brett Willis•11/5/25, 11:45 PM

Got some questions about how the image registry works when specifying the image as a registry tag rather than a Dockerfile:
1. If I push a new version of an image with the same tag, will the container instances update to the new version automatically? Or do I re-deploy the durable object (with no changes)? Or do I need to push to a new tag every time and re-deploy the durable object with the new image tag?
2. If I delete an image from the registry that is still used as the active image for a container, will it cause issues when the container needs to restart?

tao•11/6/25, 7:46 AM

Is there a way to manually trigger a redeployment of a Cloudflare Container from the web dashboard?
Our service went down unexpectedly, and we were only able to recover it by manually redeploying via Wrangler.

Brett Willis•11/6/25, 9:24 AM

Also what's up with logging from containers? When logging JSON with

console.log({ message: 'Some message' })

console.log({ message: 'Some message' })

, the output is pretty-printed and observability treats each line as a separate log, e.g.
-

"message": "{"

"message": "{"

"message": "message: 'Some message'"

"message": "message: 'Some message'"

"message": "}"

"message": "}"

If I make it not pretty-print, then observability doesn't pick up the structured JSON, it just treats it as a normal string, e.g.
-

"message": "{ message: 'Some message' }"

"message": "{ message: 'Some message' }"

And interestingly, writing to stdout with

process.stdout.write(JSON.stringify({ message: 'Some message' }))

process.stdout.write(JSON.stringify({ message: 'Some message' }))

doesn't seem to emit any observability logs at all?? Am I doing something wrong?

tao•11/6/25, 9:53 AM

Our server seems to have gone down again. The health check endpoint stopped responding for an extended period, and there were no error logs displayed on the dashboard. After redeploying a new version, we started seeing error 1101.

tao•11/6/25, 10:03 AM

After switching to another deployed version, the service started working normally again.

You could

Elia•11/7/25, 12:36 PM

Another thing, think it'd be great if there's an easy way to extend the sleepTime from inside the container

We solved it by having the container invoke the API pinging the container (causing a reset) -- but an internal API would be far more elegant imo

Alex Dahl•11/10/25, 8:54 AM

Yeah! If containers were colocated with R2 this would have been fine, but that doesn't seem to be the case, i did some benchmarking here:
containers-beta

You will be billed for the entire 24h, so yes it would impact your bill fairly heavily.
