How long should the containers take to build during local development? I'm using one of the basic go examples and the built step takes ~1 minute. Is this normal?

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.

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...

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.

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?...
