Are containers also available in Workers for Platforms?

Why do Containers charge egress fees?
I'm specifically wondering why only Containers incur egress charges, while R2 and Workers do not.
Also, if I write data from Containers to R2, will there be any egress charges?

Is there GPU support for containers? A previous blog article discussed gpus usage with cloudflare containers (internally) for your own products like browser rendering api https://blog.cloudflare.com/container-platform-preview/. Will this be available as part of the beta or in the future?

We’ve been working on something new — a platform for running containers across Cloudflare’s network. We already use it in production, for AI inference and more. Today we want to share an early look at how it’s built, why we built it, and how we use it ourselves.

If I’m already running 'wrangler dev' inside of docker (we have a monorepo where each worker in a monorepo runs in its own docker container), is there any chance this workflow would be supported for workers using cloudflare containers?

hey there! i packed my image as a docker image it's an Elixir Phoenix build with

mix phx.gen.release --docker

mix phx.gen.release --docker

.. added a wrangler.tml file with a basic config

name = "mycontainer"
compatibility_date = "2025-06-24"
[assets]
directory = "./rel"
[[containers]]
class_name = "MyContainer"
image = "./Dockerfile"

gruntlord6•6/24/25, 8:31 PM

did you deploy it already before?

G

gruntlord6•6/24/25, 8:31 PM

usually that means you just need to remove the migration

G

gruntlord6•6/24/25, 8:38 PM

or if its a new migration it means you already use that migration version

looks like creating a DO should be a code driven process (either node/python)

instance_type = "basic" # Optional, defaults to "dev"
image_vars = { FOO = "BAR" }

[[durable_objects.bindings]]

the deploy will need the DO

gruntlord6•6/24/25, 8:40 PM

haven't checked the docs that closely, if you can use the durable object directly it would make sense why you have to configure it

G

gruntlord6•6/24/25, 8:40 PM

if its something you don't control then it would make sense for them to handle that

Durable Objects migrations

A migration is a mapping process from a class name to a runtime state. This process communicates the changes to the Workers runtime and provides the runtime with instructions on how to deal with those changes.

ty @gruntlord6 i'll retry these days. it's quite a new think do me. I'm not sure why wrangler still needs the path for the final build (i assume), via

[assets]
directory = "./_build" <--- the release directory

[assets]
directory = "./_build" <--- the release directory

since a Docker file is present and generates. however, the image size is limited to 25M

Have only just started reading the docs, but am I right in thinking these containers are supposed to handle HTTP data/requests only? I can't send an RTMP stream to a container for example?

R

Rapid•6/24/25, 9:15 PM

When deploying a container it deploys it to a single location? Is the pricing relevant to a single location or edge, trying to understand exactly how it is managed, maybe I missed something
