pack VS kompose

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?

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!

Cloud Native Buildpacks

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).

Devbox analyzes your source code and instantly turns it into an OCI-compliant image that can be deployed to any cloud. The image is optimized for speed, size, security and caching ... and without needing to write a Dockerfile. And unlike buildpacks, it does it quickly.

I had a short look into buildpacks.io . So I don't have a firm opinion yet. But as much i understand now, it really builds Container images. Kubero goes a different approach. The buildstep only compiles the project to a mounted volume, which is mounted readonly to the running container. Further more is the detection step unnecessary, since the dev knows what he wants to build and selects the buildimage. How ever, I'm still looking into it, so see if my project can profit from the great work there in any other way.

Install Kompose - a conversion tool that allows you to convert your Docker Compose code to Kubernetes configuration files Run kompose convert in the same directory as your docker-compose.yml to generate the config files for your Kubernetes cluster

Kubernetes (via kompose)

As stated on their homepage, with Kompose, you can now push the same file to a production container orchestrator!. The tool definitely covers a wide range of Kubernetes features, among which these are meaningless locally but crucial for kubernetes :

deploy: stage: deploy image: alpine/k8s:1.29.1 variables: NAMESPACE: $CI_COMMIT_REF_SLUG before_script: # init namespace - kubectl config use-context $KUBE_CONTEXT - kubectl create namespace $NAMESPACE || true # download tools - curl --show-error --silent --location https://github.com/stern/stern/releases/download/v1.22.0/stern_1.22.0_linux_amd64.tar.gz | tar zx --directory /usr/bin/ stern && chmod 755 /usr/bin/stern && stern --version - curl --show-error --silent --location https://github.com/kubernetes/kompose/releases/download/v1.32.0/kompose-linux-amd64 -o /usr/local/bin/kompose && chmod a+x /usr/local/bin/kompose && kompose version # show logs asynchronously.

Adding these commands to after_script does not help - pkill stern || true - pkill kubectl || true after_script: # show namespace content - kubectl config use-context $KUBE_CONTEXT - kubectl -n $NAMESPACE get deploy,service,ingress,pod

K3s is a small, open source, no nonsense, distribution of Kubernetes. I think you'll find it just as easy to setup as Swarm. The challenge will be that Kubernetes has an entirely different API compared to Docker/Docker Compose. This can be mitigated by a tool called kompose, but using this will limit what you can do on Kubernetes.

Although I recently moved my own services from docker compose to kubernetes using https://kompose.io/ and now the only thing I run with docker compose, currently, is my private docker registry but everything including in kube, are always in their own folders.

I haven't run into the need to do that, but there is the Kompose project that exists to help with the conversion (https://kompose.io/)!

Compose claims to do that. https://kompose.io and https://kubernetes.io/docs/tasks/configure-pod-container/translate-compose-kubernetes/
