I'll toss out another vote for Fly.io. They make it super easy to deploy containers. No K8s, no leaky abstraction to an underlying traditional compute service.

I'll toss out another vote for Fly.io. They make it super easy to deploy containers. No K8s, no leaky abstraction to an underlying traditional compute service. You get internal networking out of the box with per-app-region internal DNS entries, and with their CLI tool it's one command to SSH into your container or connect your laptop to the internal network. As a nice bonus, their pricing is very competitive. You pay about as much as you would for the same size Linode or droplet (minimum is 256 MB RAM for $1.94/mo), which is a welcome relief vs other providers. Great free plan, too - 3 apps at 256MB RAM running 24/7 in perpetuity.
