J

jaden•7/7/25, 2:06 AM

In our current architecture, I want it to be similar to "worker for platform." A worker can mount multiple containers (services) and use subdomains to distribute traffic to different containers. Currently, when I look at the deployment process, containers are represented as an array. In this case, it seems that deploying multiple containers simultaneously is not feasible, as this is a distributed scenario where several deployments may occur at the same time. How can this be handled?

Tterrxo Did you get it working?

J

jaden•7/7/25, 2:08 AM

yes.

J

jaden•7/7/25, 2:23 AM

The wrangler tail prints the logs of the current worker. Is there any way to query the real-time logs of the container through a command? This is because the stack output of the container is also of concern.

Are you providing it an API token? Shot in the dark, but if you are using the default "edit cloudflare workers" template, it doesn't seem to include containers permissions by default, might be worth trying to add that permission and see if it helps

can I bind D1 somehow? do I need to talk back to the worker for D1? is the standard approach for this a websocket?
- what are the plans for mounting R2 like was discussed on the video?
- what about hyperdrive?
- I have some workloads where even with hyperdrive I can't imagine wanting to be out of the same region as my DB. and right now my containers end up on another continent.
