Use Docker Hub images with Containers

New scheduling policy for Containers to configure image and instance from Durable Objects

Containers now support the durable_object scheduling policy in public beta. This policy lets a Durable Object select the image and instance size for a Container at runtime instead of using one centrally managed configuration for the application.

Snapshot and restore Container filesystem

Containers now support snapshot APIs in public beta for saving and restoring point-in-time filesystem state. Create a snapshot first, then pass it back to start() to restore files after container sleep, restart, or handoff to another Durable Object.

Custom Container instance types no longer have a disk to memory ratio limit

Containers custom instance types no longer limit disk based on memory. Previously, a custom instance type could have a maximum of 2 GB of disk for each 1 GiB of memory. You can now allocate up to the 20 GB disk maximum to any custom instance type.

Use Cloudflare Containers with Codex via the OpenAI Agents API

The OpenAI Agents API gives your application access to Codex through an OpenAI-managed API.

Configure observability per container application

You can now configure observability for each container application when you deploy Containers with Wrangler. This lets you change logging for one container without changing the rest of your Worker.
