I've encountered an inconsistency with

I've encountered an inconsistency with how wrangler dev and wrangler deploy handle Docker build contexts. The Issue: When I place my Dockerfile in a subdirectory (e.g., cf-worker/containers/project-a/Dockerfile) and set the image field in wrangler.jsonc to './containers/project-a/Dockerfile': wrangler dev builds successfully...

When running Containers locally on macOS

When running Containers locally on macOS, fetch()ing to the Container throws a Container port not found error even after a while the Container has this.ctx.container!.start()ed, which is causing startAndWaitForPorts() to time out. Is it just me or are there any workaround, or is it a known bug? I'm using the latest template from Cloudflare....

I have a doubt about cloudflare

I have a doubt about cloudflare containers. I have a video processing work load which downlaod the video from r2 and do some processing and send the results to database. Is there any time restrictions for container run time? because it probably take more time depend upon the video size. I think container should call from worker and worker have a time execution limit.

Is there a way to access/upload to local R2 from my container or do I have to run wrangler dev --remote to work with workers + containers + r2? I'm using S3 API to interact with R2 from my container.

would be great if we could define memory

would be great if we could define memory/cpu at runtime. i have a few async job flows i deploy via cloudrun, examples are generating videos or zip files, and the amount of memory/disk space is relative to number of input files. atm i use up to 8 vcpu/16gb, so probably awhile before containers is usable as a product

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?
