rules_nixpkgs VS pack

I have spent a little bit of time working on a prototype of a setup like this, and have needed to write a lot of (hacky) glue and BUILD files.

I take it you have departed quite a bit from https://github.com/tweag/rules_nixpkgs ? Are you generating BUILD.bazel files for nixpkgs, or are you doing that by hand?

I'm a fan of Tweag's rules_nixpkgs for bazel: https://github.com/tweag/rules_nixpkgs

Check out rules_nixpkgs as another way to get hermetic python. It does require that you install Nix, but everything else is driven from the Bazel side. Works for us on Linux and macos.

Cool, thanks for the link.

For what it's worth, we use rules_nixpkgs to source Postgres (for Linux and Darwin) as well as things such as C and Python toolchains, and it's been working really well. It does require that the machine have Nix installed, though, but that opens up access to Nix's wide array of prebuilt packages.

I've recently found this quote by Kelsey Hightower:

"I'm convinced the majority of people managing infrastructure just want a PaaS. The only requirement: it has to be built by them."

In the last few weeks, I've experimented a bit with Flux (https://fluxcd.io/), Tekton (https://tekton.dev/) and Cloud Native Buildpacks (https://buildpacks.io/) on how to provide K8s powered git push deployments without using a dedicated CI/CD server.

My project is still in early alpha stage and just a proof of concept :-) My vision is to expand it into an Open Source PaaS in the future.

Do you think the above quote is true? What does an open source PaaS need to be like in order to be accepted by software developers?

Some other projects have been discontinued in the past (like Flynn or Deis) or were created before the Kubernetes era.

Is it the right direction to provide a Heroku like solution based on K8s or is it better to provide an Open Source Infrastructure as Code library with building blocks to avoid everything from scratch?

```bash (curl -sSL "https://github.com/buildpacks/pack/releases/download/v0.28.0/pack-v0.28.0-linux-arm64.tgz" | sudo tar -C /usr/local/bin/ --no-same-owner -xzv pack)

Although Dockerfiles have the benefit of migrating existing workloads to containers without having to update your toolchain, I definitely prefer the container-first workflow. Cloud Native [Buildpacks](https://buildpacks.io/) are a CNCF incubating project but were proven at Heroku. Buildpacks support common languages, but working on a Go project I've also had a great experience with [ko](https://ko.build/). Free yourself from Dockerfile!

It's big and overwhelming and sometimes scary. But you know what? It's also fun, engaging, and very refreshing. Because I'm a DevRel, I don't have many chances to focus on something particular. Still, I'm having a lot of fun exploring different CMSs (like Statamic, Craft, or Sanity), new approaches (at last, I understood why the headless approach is so important), and diving into tech I never used before (hello Buildpacks).
