Hi, when dose cf release the containers server ? Can I use containers beta in PRD environment ?

When you connect to a Git repo, it'll create an API token for you as part of that process

scotto•8/8/25, 11:31 PM

Then that's not working right, I connect the repo and got that error only for containers, the worker it selft deploys normally

kian•8/8/25, 11:32 PM

Have you checked the token has the Containers permission?

scotto•8/8/25, 11:40 PM

How can I check that if it's automated as far as I know

gnarley_farley.OP•8/9/25, 2:23 AM

Egress on containers is so expensive. All the best use cases I can think off like processing video are just totally out of reach. We did the maths on moving our ffmpeg processing to containers. Mind boggling numbers. What a pity, cloudflare has always been very generous with egress.

Hello

Can I run ffmpeg on containers?

SSamandar Turdiev Can I run ffmpeg on containers?

Isaac McFadyen•8/9/25, 5:04 AM

Yes, with some caveats that encoding video using h264/h265 can be somewhat slow even on the highest tier available currently.

Isaac McFadyen•8/9/25, 5:05 AM

But for transcoding or encoding lightweight formats like audio it runs well.

I just want to encode aac audio to mp3, average file size 50Mb

Samandar Turdiev•8/9/25, 5:16 AM

What do you think, free tier is ok for my case?

gnarley_farley.OP•8/9/25, 5:26 AM

you can run ffmpeg there is one tutorial on youtube. I even got yt-dlp to run on it yesterday. Bit slow though. Cold start times are gnarley. Egress is expensive.

But if you just using it for your personal stuff it will be good. Try it out.

You get 500gb-1tb free depending on your region... Or something liek that according to the docs.

1984 Ford Laser•8/9/25, 7:21 AM

Thats still a decent included tier. I process a couple hundred 3+ hour videos a month and could get through all of my monthly usage within the provided tier

Samandar Turdiev•8/9/25, 7:35 AM

Is Worker ineffiecnt for such cpu-intesive tasks?

1984 Ford Laser•8/9/25, 7:37 AM

correct

Samandar Turdiev•8/9/25, 7:40 AM

What can you recommend instead? I'm doing a massive conversion of audio files on-the-fly, per request, I need to offlod encoding process

gnarley_farley.OP•8/9/25, 7:40 AM

For Personal usage. For any app or service it's too expensive. Workers don't support the packages and also stuff like unsafe eval so not an option. Cool thing about containers is they support everything.

1984 Ford Laser•8/9/25, 7:40 AM

An app or service should be adequately monetised to cover such costs

gnarley_farley.OP•8/9/25, 7:46 AM

Too expensive. Egress fee's for things like uploading to r2 make i very pricey. For personal usage sure. Very nice

gnarley_farley.OP•8/9/25, 7:47 AM

Let's see how widely adopted this becomes in the next few months to a year.

gnarley_farley.OP•8/9/25, 7:49 AM

If it's for users try offload to their personal computers with something like a companion app. If you have to do it remotely checkout the price of vm's. You can get them for betwen 100x to 1000x cheaper than containers depending on your workloads.

Samandar Turdiev•8/9/25, 7:51 AM

Companion app?

gnarley_farley.OP•8/9/25, 7:52 AM

Things like ffmpeg or yt-dlp can be run off a users computer. You can make users install a binary or application on their personal computers that can interface with your service in some way. So they can make use of your software but using their personal resources

Samandar Turdiev•8/9/25, 7:52 AM

I'll try to check vm options

gnarley_farley.OP•8/9/25, 7:53 AM

Check racknerd and try find their specials or some other service. Yearly costs are pretty low. You can upload to s3 or r2 and then make downloadable links from there.

1984 Ford Laser•8/9/25, 8:12 AM

Whats latency like if they don't have a nearby DC?

gnarley_farley.OP•8/9/25, 8:12 AM

Better than 13 second cold starts on containers. Forsure.

1984 Ford Laser•8/9/25, 8:13 AM

What does it cost to get more bandwidth?

gnarley_farley.OP•8/9/25, 8:13 AM

A lot

gnarley_farley.OP•8/9/25, 8:14 AM

Depends though on your use case. If you processing video for users

gnarley_farley.OP•8/9/25, 8:14 AM

This is way too expensive

1984 Ford Laser•8/9/25, 8:14 AM

no with racknerd I know how to read CF docs

gnarley_farley.OP•8/9/25, 8:14 AM

They have a lot of unlimited plans

gnarley_farley.OP•8/9/25, 8:15 AM

For like 200$+ a year for a pretty sick vm and unlimited download and upload

gnarley_farley.OP•8/9/25, 8:17 AM

Example 7tb per month for 28$ per year.

gnarley_farley.OP•8/9/25, 8:18 AM

1 tb for cf containers cost more than this yearly cost.

1984 Ford Laser•8/9/25, 8:18 AM

CF Containers isnt intended to be a 24/7/365 product

gnarley_farley.OP•8/9/25, 8:19 AM

where you get 84 terrabytes of egress.. yeah we not looking for 24/7 products.

1984 Ford Laser•8/9/25, 8:19 AM

the egress is also cheaper than what aws charges for ec2 at least in my region

gnarley_farley.OP•8/9/25, 8:31 AM

Let's compare to their own services instead. I would happily pay them 1 bar a month at the right price. The current fee's just make it something we won't ever use. End of story

Code Cowboy•8/9/25, 2:30 PM

Error checking 8787: connect(): Connection refused: container port not found. Make sure you exposed the port in your container definition.

Error checking 8787: connect(): Connection refused: container port not found. Make sure you exposed the port in your container definition.

Why is it checking 8787? Also anybody found a way to fix this?

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

Code Cowboy•8/9/25, 2:40 PM

Wow @Eelco you are a legend, downgrading to 0.0.19 fixed local dev for me, super frustrating

anyone else seeing this intermittent abort error when starting with startandwaitforports.

pandalambda2•8/10/25, 3:43 AM

do containers work with cloudflare tail log workers? trying to understand how I can push logs to axiom logging service without changing app code, sticking logpush product behind an enterprise account seems an odd decision given infrastructure manages the logs is a core part of the 12factor methodology.

Sscotto How can I check that if it's automated as far as I know

scotto•8/10/25, 6:34 PM

Any help @kian ?

berkant•8/10/25, 9:32 PM

Hi, do Cache Rules or stuff like

{cf: {cacheEverything: true}}

{cf: {cacheEverything: true}}

apply to containers if called fetch on them?
