Hello all! 

I'm hoping for some general help getting started with DPDK in a Containernet topology. I have some DPDK experience, but I'm very new to container networking :). I've been working with an Ubuntu 24.10 VM, though I can run any experiments on Cloudlab (so am not necessarily tied to a particular architecture). 

Second question: I'm having trouble creating containers that will let me run DPDK applications. High-level, I understand that I'll need to create or find a container image that's configured with DPDK and all dependencies, as well as the Containernet requirements. 

I tried to build on this: https://github.com/shanakaprageeth/docker-dpdk . However, when I ran the setup script, I get this error:

```
ERROR: failed to solve: process "/bin/sh -c apt-get install build-essential git python pciutils vim -y" did not complete successfully: exit code: 100
Unable to find `image 'ubuntu-dpdk:latest' locally
docker: Error response from daemon: pull access denied for ubuntu-dpdk, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
```

When I downloaded the image directly from docker (docker pull shanakaprageeth/ubuntu-dpdk), no commands on the container worked (ifconfig, apt-get, etc.). There was no error message.

I think I fundamentally don't understand how container images work and how to customize them, especially since I'm trying to write Containernet scripts (vs. actually ssh-ing into containers). I know I'll need a container that supports DPDK and has it downloaded, and I know it will also need to meet the Containernet requirements.

Could anyone please point me in the right direction?

Thank you!
