fission VS rke2

Fission

This is where I see K8S coming in – teachers can provide dev deployments that are setup for students to learn. Teachers can also provide containers that run automated tests against the student containers for assessment! Plus, we can smooth over some of the git workflow stuff for the ripest of beginners; we can integrate with github to sync their work on our platform to repositories on their github account, so that they can really take ownership of the work they do on the platform. Last, students can graduate their work from development into production very easily, since we can take the base images + student diffs, build a new "prod" image for the student. We can run students' prod work on "serverless" K8S frameworks like fission or OpenFaas to be able to host many low-traffic "production" apps at the same time.

I use https://fission.io/ on Kubernetes to emulate AWS Lambda + API Gateway to run Python functions. I use their YAML Spec functionality to deploy functions. It works well for my use case.

After doing a lot of research, I ended up settling on the Fission.io framework to support this project. Fission is an open-source Serverless framework running in kubernetes. Think AWS Lambdas, but we are in control of every part of the infrastructure. Kubernetes gives us the power to define the environments the containers will be executed in, and any other resources they need. This gives us the control we need to be able to create our very own environment for executing arbitrary JavaScript through the V8 engine. Each function can be isolated as much as we need to and Fission is really great at giving us the ability to quickly create multiple environments.

Nope. I was using https://fission.io/

There are a lot of FaaS service offerings out there namely Lambda, Azure Functions, Google Cloud Functions to name a few. While these offerings run on their respective clouds, there are services like Fission that are open source and allow you to deploy and execute functions on Kubernetes clusters irrespective of where they reside.

It's super slow (20-50 rps), please try this instead : https://github.com/fission/fission (few hundreds to few thousands rps)

In this essay, we showed how to use Rancher rke2 to deploy a Kubernetes cluster with 6 Debian nodes with firewall enabled. We've also covered deploying Cilium as a CNI for our cluster and have it completely replace kube-proxy so as to increase speed and gain more observability via Cilium tools. This article also showed how to deploy Metallb to manage IP pools and load balance traffic for those IP pools. Throughout this guide, we assumed that we have an external load balancer that will distribute traffic to our workload and control plane nodes. For further information please visit rke2 official documents: "https://docs.rke2.io/".

In this blog post, we will demonstrate how easy and fast it is to deploy Sveltos on an RKE2 cluster with the help of ArgoCD, register two RKE2 Cluster API (CAPI) clusters and create a ClusterProfile to deploy Prometheus and Grafana Helm charts down the managed CAPI clusters.

Did something happen to the Apache 2 rancher? https://github.com/rancher/rancher/blob/v2.7.5/LICENSE RKE2 is similarly Apache 2: https://github.com/rancher/rke2/blob/v1.26.7%2Brke2r1/LICENS...

To provision all of my clusters, I use Rancher with RKE2. The primary Rancher server is hosted on a bootstrapped RKE2 cluster running on a VPS.

Golang has burned me more than once with bizarre design decisions that break things in a user hostile way.

The last one we ran into was a change in Go 1.15 where servers that presented a TLS certificate with the hostname encoded into the CN field instead of the more appropriate SAN field always fail validation.

The behavior could be disabled however that functionality was removed in 1.18 with no way to opt back into the old behavior. I understand why SAN is the right way to do it but in this case I didn’t control the server.

Developers at Google probably never have to deal with 3rd parties with shitty infrastructure but a lot of us do.

Here’s a bug in rke that’s related https://github.com/rancher/rke2/issues/775

just looking at this myself. I think k3s has more support for arm, but looking through the github repo there are a lot of bugs indicating its a mess. RKE2 seems to be their big push, they also have a github issue open that has been open for the last 2 releases that they are going to add a update path from k3s to rke2. https://github.com/rancher/rke2/issues/881
