Containers with azure functions

hello lately I have started a new project that have few apps hosted on azure functions, but not as a container. I want to start deploying the apps as containers in azure functions.

the base image is pretty big, the base azure function for node is around 2GB. I used dive to get inside, and I have found there are some unused runtimes installed and some azure function bundles with older version that I can delete.

with cleaning and using slim version, I can get the base image to 1 GB.

I was wondering if you have any tips and tricks for containerized azure function to keep the image small.

cheers

15 Years of DevOps, yet manual schema migrations still a thing

Hey All,

My name is Rotem, co-founder of atlasgo.io

One of the most surprising things I learned since starting the company 4 years ago is that manual database schema changes are still a thing. Way more common that I had thought.

We commonly see this is in customer calls - the team has CI/CD pipelines for app delivery, maybe even IaC for cloud stuff - but the database - still devs/DBAs connect directly to prod to apply changes.

This came as a surprise to me since tools for automating schema changes have existed since at least 2006.

Our DevRel Engineer u/noarogo published a piece about it today:

What's your experience? Do you still see this practice?

If you see it, what's your explanation for this gap?

Getting env file to digitalocean droplet

Hello I currently have a next.js app and I'm currently deploying to digitalocean droplets using github actions, but I'm kind of confused on how to get my .env file to the droplet. Would I manually just add it to the cloned repo on the droplet? Or scp my env to the droplet. Or some other way? I'm a bit new to this.

What tool are you using for easy provisioning?

Hi, I am experimenting with self managed kubernetes cluster. Kubernetes is cool and all but the underlying servers where the pods run on still need to be provisioned and managed. I understand that terraform can create/manage the infra resources such as network, storage, vm etc. But for provisioning other tools such as Ansible is used. I am looking for an easy to use with web ui preferably to provision my servers.

Starting DevOps role, but no prior experience

I’m starting a DevOps Azure Team Lead. I have long history leading agile teams, but no real hands-on experience in DevOps. I’m pretty sure I’m gonna be just fine, but I would like to thrive.

Hence my question - what’s the fast-track to learn the DevOps craft? With so many tutorials out there, I’d like to know which one to choose or start from. Any recommends?

Starting my selfhosting journey - k8s or docker?

Hello all, i feel ready enough to start practicing and suffering with my homelab in order to improve my skills on common devops topics and to give a try to a bunch of r/selfhosted projects. Now i'm simply wondering, portainer or kubernetes ? I have a single mini-pc node setup with ubuntu server + docker/podman + minikube running on it. Initially, no network drives, everything will resides on the local disk machine so i need a pretty much easy setup and i don't care so much about FT and DR.

Trying to analyze the two architectures, i would say that the kubernetes one is more reliable and more interesting, but sometimes helm charts aren't updated or they are a bit messy to investigate or manage. But storage and networking would probably be much easier (a single ingress with multiple path, one for each service).

Instead running everything on pure docker with a management system like portainer would be probably easier to manage but dunno if this can really help me in enlarge my skills and if the pure docker approach can be a little bit "aged".

What's your point about this ? Any suggestions or insights ?

Many thanks !

Simple, self-hosted GitHub Actions runners

I needed more RAM for my GitHub Actions runners and I couldn't really find an offering that I could link to a private repository (they all need organization accounts?).

Anyways, I have a pretty powerful desktop for dev work already so I figured why not put the runner on my local desktop. It turns out the GHA runner is not containerized by default and, more importantly, it is stateful so you have to rewrite the way your actions work to get them to play nicely with the default self-hosted configuration.

To make it easier, I made a Docker image that deploys a self-hosted runner very similar to the GitHub one, check it out! https://github.com/kevmo314/docker-gha-runner

Perplexity for DevOps

Hey !

We’ve been building Anyshift, the Perplexity for DevOps. It answers questions like:

* “Are we deployed across multiple regions or AZs?”
* “What changed in my DynamoDB prod between April 8–11?”
* “Which accounts have stale or unused access keys?”

and make detailed answered with verified sources (AWS URL, git commits etc...)

Behind the scenes, it queries a live graph of your code and cloud with no hallucinations, just real answers backed by real data from:

* GitHub (Terraform & IaC)
* Live AWS resources
* Datadog

Why we built it:
Terraform plans are often opaque. One small change (like a CIDR block or SG rule) can trigger unexpected consequences. We wanted visibility into those dependencies — including unmanaged or clickops resources

Under the hood :

* We use Neo4j graph updated via event-driven pipelines
* We provide factual answers with links to source data
* It can be used as a Slackbot or web UI

The setup takes \~5 mins (GitHub app or AWS read-only on a dev account to test it quickly).
And its free for teams up to 3 users :) [https://app.anyshift.io](https://app.anyshift.io)

Would love your feedback — especially around Terraform drift, shadow IT, or blast radius use cases.

Thanks a lot :)))

Kubernetes Scaling: Replication Controller vs ReplicaSet vs Deployment - What’s the Difference?

Hey folks! Before diving into my latest post on Horizontal vs Vertical Pod Autoscaling (HPA vs VPA), I’d actually recommend brushing up on the foundations of scaling in Kubernetes.

I published a beginner-friendly guide that breaks down the evolution of Kubernetes controllers, from ReplicationControllers to ReplicaSets and finally Deployments, all with YAML examples and practical context.

Thought of sharing a TL;DR version here:

ReplicationController (RC):
1. Ensures a fixed number of pods are running.
2. Legacy component - simple, but limited.

ReplicaSet (RS):
1. Replaces RC with better label selectors.
2. Rarely used standalone; mostly managed by Deployments.

Deployment:
1. Manages ReplicaSets for you.
2. Supports rolling updates, rollbacks, and autoscaling.
3. The go-to method for real-world app management in K8s.

Each step brings more power and flexibility, a must-know before you explore HPA and VPA.

Would love to hear your thoughts, what part confused you the most when you were learning this, or what finally made it click? Drop a comment, and let’s chat!

Check out the full article with YAML snippets and key commands here:

First, Why You Should Skip RC and Start with Deployments in Kubernetes

📌 Case Study Changing GitHub Repository in AWS Amplify — Step-by-Step Guide

Hey folks,

I recently ran into a situation at work where I needed to change the GitHub repository connected to an existing AWS Amplify app. Unfortunately, there's no native UI support for this, and documentation is scattered. So I documented the exact steps I followed, including CLI commands and permission flow.

💡 Key Highlights:

Temporary app creation to trigger GitHub auth
GitHub App permission scoping
Using AWS CLI to update repository link
Final reconnection through Amplify Console

🧠 If you're hitting a wall trying to rewire Amplify to a different repo without breaking your pipeline, this might save you time.

What is usually done in Kubernetes when deploying a Python app (FastAPI)?

Hi everyone,

I'm coming from the Spring Boot world. There, we typically deploy to Kubernetes using a UBI-based Docker image. The Spring Boot app is a self-contained .jar file that runs inside the container, and deployment to a Kubernetes pod is straightforward.

Now I'm working with a FastAPI-based Python server, and I’d like to deploy it as a self-contained app in a Docker image.

What’s the standard approach in the Python world?
Is it considered good practice to make the FastAPI app self-contained in the image?
What should I do or configure for that?

Is 2025 CKA harder than it was before? (Rant)

I waited to post this for a few months.

For context, I started my Kubernetes journey fresh in September 2024, having minimal experience (only with docker and docker-compose, but no orchestration, but I have sys admin/devops experience). I went through whole KodeKloud course, I did all 70+ killercoda scenarios and scored 80% on my killer.sh attempt. I probably spent 120+ hours studying and practicing for this exam.

I took the exam the updated exam on 1st of March 2025, so I knew about the updates and I went over the additional stuff as well. I took multiple kodekloud mock exams, with mixed results. But I read a lot about how killer.sh is much harder than real CKA exam, so when I scored 80% on my practice attempt so I was pretty confident going into the exam (maybe I was just lucky that the killer.sh questions suited me).

When I started the exam, oh boy: flaged 1st, flaged 2nd, flagged 3rd... I think the first question I started solving was 7 or 8th. I could've written down with what exactly I struggled, but I felt it was much harder than killer.sh. I think I can navigate the K8s docs pretty well, but I know I had some Gateway API questions, but I feel the docs were non existent for my questions, then also why use helm, and not allow helm docs? I remember I had to install and configure CNI, but why would you allow the docs/github for it? Does every Certified Kubernetes Admin know this from top of their head? Even when there is an update? I know there was somethings such as resource limits on the nodes I could've had and studied better for.

So after 2hours, I scored 45% (probably better than 60-65% as I would be more angry at myself but also more confident for the retake).

So I wanted to ask some who did the exam before and retook is after the February update: Was the exam harder? Or am I just stupid?

By end of this month I want to start revising again and do the retake in July/August. Do you guy have any other resources than KodeKloud, killercoda and killer.sh? I'm buying a hertner vps and going to host something in K8s to get more real-life experience.

End of my rant.

Edit: I'm not time traveller, fixed

The first time I ran terraform destroy in the wrong workspace… was also the last 😅

Early Terraform days were rough. I didn’t really understand workspaces, so everything lived in default. One day, I switched projects and, thinking I was being “clean,” I ran terraform destroy .

Turns out I was still in the shared dev workspace. Goodbye, networking. Goodbye, EC2. Goodbye, 2 hours of my life restoring what I’d nuked.

Now I’m strict about:

Naming workspaces clearly
Adding safeguards in CLI scripts
Using terraform plan like it’s gospel
And never trusting myself at 5 PM on a Friday

Funny how one command can teach you the entire philosophy of infrastructure discipline.

Anyone else learned Terraform the hard way?

Discussion: Model level scaling for triton inference server

Hey folks, hope you’re all doing great!

I ran into an interesting scaling challenge today and wanted to get some thoughts. We’re currently running an ASG (g5.xlarge) setup hosting Triton Inference Server, using S3 as the model repository.

The issue is that when we want to scale up a specific model (due to increased load), we end up scaling the entire ASG, even though the demand is only for that one model. Obviously, that’s not very efficient.

So I’m exploring whether it’s feasible to move this setup to Kubernetes and use KEDA (Kubernetes Event-driven Autoscaling) to autoscale based on Triton server metrics — ideally in a way that allows scaling at a model level instead of scaling the whole deployment.

Has anyone here tried something similar with KEDA + Triton? Is there a way to tap into per-model metrics exposed by Triton (maybe via Prometheus) and use that as a KEDA trigger?

Appreciate any input or guidance!
