Hi, first of all thanks for finally supporting containers
Now while trying to check the support as described on https://vercel.com/blog/dockerfile-on-vercel post I ended up with a 404, and the deployment logs don't mention any container build taking place, maybe something is still missing from the overall approach?
Regards, Paulo Pinto
Hi thanks for replying, naturally, hence why I linked the blog post as well as starting point,
Also as feedback for the documentation, it would be more interesting if it used more common languages used in container development like Java, Go, C#, not JavaScript examples.
Anyway, my approach was while following the blog post:
14:06:44.828 Running build in Washington, D.C., USA (East) – iad114:06:44.828 Build machine configuration: 2 cores, 8 GB14:06:44.842 Retrieving list of deployment files...14:06:44.845 Skipping build cache, deployment was triggered without cache.14:06:45.388 Downloading 2 deployment files...14:06:45.696 Running "vercel build"14:06:45.716 Vercel CLI 54.18.614:06:45.960 Build Completed in /vercel/output [25ms]14:06:46.031 Deploying outputs...14:06:47.174 Deployment completed14:06:47.273 Creating build cache...14:06:47.286 Skipping cache upload because no files were preparedThe files placed at the project root as described in the blog post
Nothing seems to have come out of it as well, other the middleware file.
Some additional information.
The samples on https://vercel.com/docs/functions/container-images seem to clearly be ignoring containers as well.
Node.js and srvx dynamic server example is actually being deployed via Deploy a Node.js server capability
Whereas Nginx static server example, basically returns the index.html directly without any use of ngix.
In any of the examples, the log as shown on the blog post isn't visible.
Instead of

Hi,
finally got it working, the missing part from documentation is that project type has to be configured for Container.
Vercel build doesn't recognize the project automatically as a container project, even with the presence of Dockerfile.vercel, Container.vercel files.
I have sorted out by manually setting Framework presets to Container under Framework Settings.
Thanks for figuring out what was missing!
On a new project it would have automatically detected the Dockerfile.vercel and used the Container preset. I opened an internal ticket to get the docs updated with a note about changing the preset for cases where it can't be automatically set.
