Docker buildx support

Is there a way to use docker buildx with wrangler deploy? I had to create a custom builder for my environment via docker buildx create but wrangler is not using it.

I don't quite understand what I did, but I seem to have an endless series of timers that constantly respawn my dead containers when i wrangler deploy they all go inactive, but then they pop back up again, presumably because of the alarm triggers 💀 (just wanted to flush some logs to R2 every 60s) ...

hey all - i am updating from the alpha

hey all - i am updating from the alpha to the beta to be able to have some automagic building of our image for local development. should simplify a lot of our setup, but we're using the vite plugin, and i'm unclear on support here? the image doesn't show up in .wrangler after i spin up the app. if i use wrangler dev i do see it picks up on the container and tries to build it. i'm on: wrangler 4.21.2...

I'm pushing an update to an existing container, I get a successful reply from wrangler containers push (though, it was suspiciously fast): `` ⛅️ wrangler 4.21.2 ─────────────────── ▲ [WARNING] 🚧 wrangler containers push` is an open-beta command. Please report any issues to https://github.com/cloudflare/workers-sdk/issues/new/choose...

Follow-up question - is there any good example of a simple websocket pass-through proxy for passing through websocket connections to a container?

Is there any flow which would permit running an existing docker container image? I have a high-performance rust application that already has a working docker build. I would like to try to run this with limited modifications, as a spike test.

I see this in the FAQ
Container cold starts can often be the 2-3 second range, but this is dependent on image size and code execution time, among other factors.
Is this an estimate based on a certain size container?...

@Mike Nomitch - Any suggestion with containers in regards to splitting video/audio conversion between containers and a vps? I heard 50mb or less for containers but I am curious your thoughts on what it can handle.

I'm trying to deploy just the hello-containers example but on npm run dev it builds and hangs at Starting local server.... I can access the main page with listen endpoints but navigating to any of them results in 500 errors. All setup using defaults for that template. This is in WSL context.

The blog that announced containers are

The blog that announced containers are coming explicitly mentioned ffmpeg, but I can't see anyway of making this work. The compression example is the closest, but I don't even see how that would work when the response needs to fit inside 1MB? R2 bindings don't work with containers either, right? Is there any examples of ffmpeg to checkout?...

Still getting stuck here, I just can't figure out why it doesn't like my setup. - My app is definitely running on 8080 - My image is within all limits - If I pull and run the image locally everything works completely fine ...

i saw a couple of questions re: long-

i saw a couple of questions re: long-running containers (e.g. a Discord bot), is that a use case that CF containers support? it seems like this could be hacked together with a cron acting as a keepalive and a long value for sleepAfter, but are there other limitations to be aware of?

am i reading this correctly that containers still require you to run a node cf worker and route requests to the container? I was hoping I could just deploy a docker image without any worker glue sitting in front

I'm assuming my container is not

I'm assuming my container is not starting in dev because onStart is not called (and docker ps returns nothing) but it is impossible to debug. I'm not getting any logs or error messages from inside the container, only the fetch error from the worker to the container? When deploying it is the same but I do get some messages (e.g. Error checking 4848: The container is not listening in the TCP address 10.0.0.1:4848) but still nothing useful... How can I access the logs from what is happening inside the container?...

quite a useless question, however does anyone know roughly when containers could expect to be released in GA (e.g. is it expected to follow the same timeline as CloudFlare Workflows: Oct 24, 2024 - beta, 6 Apr 2025 ~~ so roughly 6 months?)
