Knative Functions - No Dockerfile, No Lock-In, No Kubernetes Experience

Would you like to run functions in your own Kubernetes clusters? Would you like it to be as simple as possible? How about providing Functions As a Service (FaaS) flavor of serverless computing to everyone in your company? If the answer to any of those questions is yes, you might want to explore Knative Functions.

[@felipeozoski]

my new favorite channel!! we appreciate you man, thanks!

[@fabianbrash4356]

Yes I work for VMware and we use knative for our Tanzu Application Platform, it generates a URL and runs your backend as a function and scales to zero. Pretty sweet!!

[@JaydeepDave12]

I used this at my previous company, but it was lost somewhere in notes. Thanks for bringing this up, I will keep try to implement this when and where possible.

[@sharonvendrov1885]

Thank you for another great video!
Another advantage I can find is that in many organizations Lambda functions and all components around it, are managed as IaC which sometimes might bring some overhead that Knative functions seem to solve. Disclaimer: This is my personal impression without a real HO with Knative.

[@uziboozy4540]

You are in full control with Kubernetes & Knative, whereas you have absolutely no control over Lambda.
Lambda is probably one of the most overrated cloud services in the world, as are all of AWS services 🤷‍♂️

[@leonluis]

Interesting approach, gotta try it :)

[@KnThSelf2ThSelfBTrue]

I feel like it's easy enough to just copy Okteto's OpenFaaS example implementation to get yourself bootstrapped into self-managed serverless development, but I wonder if Knative Functions integrates better with other eventing/scaling tooling in the Knative ecosystem. Interesting stuff!

I just tried this with --language springboot and its just insanely slow, on a Mac M1. I mean already 10 minutes in, and it has not started yet. The video is awesome though. thank you for it.

[@DevOpsToolkit]

I haven't used it with Java/SpringBoot, but my guess is that the issue is with Buildpacks and the base image it's using.

[@57skies]

@@DevOpsToolkit neah, its something to do with Spring : "Total time: 12:01 min" seems odd.

[@lanceball68]

The springboot builds on an M1 mac require cross compilation which can definitely take forever. Unfortunately until the buildpack ecosystem improves the arm64 options, these builds will just be slow on a mac. :/

[@masu4644]

how can I use knative functions to activate a service which has to scale up or down depending on the amount of message in a kafka topic?

[@DevOpsToolkit]

You might want to try OpenFunction which, among other things, does that. You'll find a video in this channel.

[@masu4644]

thanks for the fast answer and suggestion, I will check that out@@DevOpsToolkit

[@masu4644]

after wachting your video and doing some research, I think that knative and keda will fit better, or am I missing somthing?@@DevOpsToolkit

[@DevOpsToolkit]

@@masu4644 that's it. That's the combination OpenFunction does but you can do it without as well by simply combining knative and keda.

[@someone-lx8mg]

What do you think about fission?

[@DevOpsToolkit]

I did not yet use it enough to judge Fission or compare it with other solutions :(

[@someone-lx8mg]

@@DevOpsToolkit thanks for your high quality educational videos

[@madhank93]

Another awesome video. What do you think about OpenFaaS ?

[@DevOpsToolkit]

I haven't used it in a while so I'm not up to date with OpenFaaS :(
