Docker containers usually still reachable even if bound to 127.0.0.1
rkt (and many other container solutions) was introduced after docker was released and became popular... they even mentioned docker's shortcomings as a motivation for the project creation [0]. It had all the same problems as other replacement software: there were plenty of bugs and missing features, documentation was limited, and there are no community to help you (the announcement explicitly mentions "prototype quality release"). None of those would be fatal if it was significantly better than docker, but it was not -- it was basically the same functionality. So almost no one made the switch. It is closed now [1]
And why "rkt"? There were much better alternative container runtimes. For example Sylabs Singularity [2] -- container-as-a-file, instant mounting, etc... I wish more people knew about it.

ELI5: Why does the FreeBSD community hate Docker and Kubernetes so much?
Docker (and the current generation of OCI runtimes) is rather shitty at host OS isolation too. It may have started well, but over time more capabilities were added for the convenience of developers and at the cost of maintainers. I would personally love if the ecosystem were to shift to more isolated workloads with better HPC support. Singualrity looks promising but still maintains OCI compatibility.

Quadlets might make me finally stop using Docker-compose – Major Hayden
Whole quadlets are cool, this just means me miss the rkt runtime. https://github.com/rkt/rkt It integrated with systemd properly quite a while ago.

Using Docker to Containerize Laravel Apps for Development and Production
Think of Docker as the AWS of the container world in terms of popularity, there is another container platform called rocket (rkt) which can be considered something like Vultr in this analogy.
- I have created a curated list of startup tools in a single page, No Signup, No Login, No Clutter
What are some alternatives?
apptainer - Apptainer: Application containers for Linux
toxiproxy - :alarm_clock: :fire: A TCP proxy to simulate network and system conditions for chaos and resiliency testing
singularity-cri - The Singularity implementation of the Kubernetes Container Runtime Interface
confd - Manage local application configuration files using templates and data from etcd or consul
singularity - Singularity has been renamed to Apptainer as part of us moving the project to the Linux Foundation. This repo has been persisted as a snapshot right before the changes.
