Dev podcast listeners - what do dev podcasts never talk about?

Basically the title. If you listen to dev podcasts, what topics do you feel are not getting enough attention? What should be talked about more? What would you like to hear?
I'm an editor at a new dev podcast, I feel like "Top 10 AI dev tool" listicles created with ChatGPT are getting kind of boring. Would love to hear your thoughts.

Is there any good Open Source Alternative to Ploi, RunCloud, ServerPilot...

Like the title said, is there any open-source alternative to those services that is equal in features?

I want an open source alternative that I can install on one server and have the ability to connect an manage many other servers.

A question about how pods creation with requests

Hi guys,
I am new to kubernetes I need some direction to what ways can I create a pod with each request, for example 2 request hit and then 2 pods will create and then when the request is finished then 2 pods should kill with autoscale . I have been explored custom metrics but I don't know how to write conditions. If someone already worked can you please send some references links or somebody give any ideas to create pods based on the requests . I have been using load balancer as metal LB cluster for LB.


Thanks in advance

liberal arts major switching to a career in DevOps.

I did my undergrad in a liberal arts degree and I'm looking forward to switching my career into tech.

I'm not very proficient but I have tried my hands at Django, React and Postresql, tried MERN stack too ( I didn't really stick with it but if you asked me to build a simple demo app using one of the stacks I will know how to go about it)

I graduated with a BA last year and I've applied for MS in Computer science at a few unis in the UK ( since the UK has a lot of masters programs in CS for non-cs undergrads like me )


now I heard from a few of my friends from the UK that they hire only people who have experience, especially in DevOps and how finding internships in the UK is harder since there are a lot of international students applying for the same job posts.

so my question is :

Let's say I managed to grind through and get certs in Azure Fundamentals, or any one of the associates certification. Would the fact that I had no previous industry experience affect my job prospects? Can I apply for entry level jobs?

ingress-service.175a4928eb9af7d0SyncScheduled for sync nginx-ingress-controller -3 an hour ago 20 minutes ago

I was able to set up ingress, and I was using "Docker and Kubernetes The Complete Guide" configs for the ingress, but it seems it doesn't work at all and I can't connect to [192.168.49.2](https://192.168.49.2), because it's still scheduled for sync. Is the config 100% deprecated? Because in the tutorial it works locally with minikube, but I can't access it on my local machine after fixing the deprecated configs that no longer works.

&#x200B;

Is there a really easy way to set it up now, because everything seems to be deprecated. He's also not using the official ingress library.

Help with upcoming devops interview

Hi guys, I am a recent software engineering bootcamp grad and I have a devops engineer interview in a few days. It’s for a apprenticeship - so very junior. Although I don’t know much about devops I would love to get this job. I have to give a presentation on devops, the future of the devops etc. does anyone have any tips on what I might what to research or include in the presentation that would be great!

Anyone want a mentor? Staff engineer looking to pay it forward

Hey folks,

I was promoted to staff engineer a few months ago and this community was instrumental in getting me started on the wonderful road of DevOps about 6 years back.

Given that, I'd like to pay it forward and offer ongoing mentorship to one, maybe two people.

I'm imagining having weekly video chats of about 30-50 minutes where we can discuss areas where you'd like to grow, be they soft or technical skills. If there's an appetite, it could also be fun and helpful to work on practical exercises together.

A little about me, I work for a SaaS company in a department of about 80 technologists and am responsible for developer productivity, cloud infrastructure architecture (Azure), and quite a bit of cybersecurity.

Here's how I see the ideal mentee:

* Already working in a software role with some DevOps responsibilities
* Able to meet weekly or biweekly at a reasonable time (Eastern Time)
* Has a goal in mind to start the conversation
* Precocious but more importantly is a hard worker
* Speaks English fluently

If this sounds like you and you'd like to chat then please shoot me a PM with a few paragraphs introducing yourself, describing your background, and topics that you'd like to start with.

If you're not already working in a software role but think you would be an excellent mentee, then by all means drop me a line anyway.

Cheers!

how do you map your deployment to the ingress-nginx-controller locally?

$ kubectl get service ingress-nginx-controller --namespace=ingress-nginx

ingress-nginx-controller LoadBalancer 10.108.27.17 127.0.0.180:32606/TCP,443:32504/TCP 21m

&#x200B;

I am confused, because the starting config I had was:

&#x200B;

apiVersion: apps/v1
kind: Deployment
metadata:
name: app-deployment
spec:
replicas: 1
selector:
matchLabels:
app: myapp

ports:
- containerPort: 3000

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: 'nginx'
nginx.ingress.kubernetes.io/use-regex: 'true'
nginx.ingress.kubernetes.io/rewrite-target: /$1

kind: Service
metadata:
name: my-ip-service
spec:
type: ClusterIP
selector:
app: myapp
ports:
- port: 3000
targetPort: 3000

I had to modify the config, because it used a deprecated version, but it seems like the starter yaml was also changed, which meant that I had to use minikube tunnel to get the loadbalancer working, but in the old tutorial we didn't need a load balancer it just worked without it, so how do I fix my config, I am kinda confused. I am thinking I need to map it to 32606 instead, but I am thinking it might be an internal port that's used internally by kubernetes.

First interview was a disaster

I picked up the 3 associate AWS certs last year with the last being in October. I’ve been teaching myself Python and doing small personal projects since.

I interviewed for an entry engineering position internally at my company on Thursday. It was a technical interview and that’s really all I knew going into it. I was expecting the format to be cloud scenario based questions and maybe talking through how I’d solve a few Python problems. I was so wrong.

Instead, it was AWS trivia and live coding. It almost felt like a ‘gotcha’ interview. I was asked things I definitely would’ve known if I was fresh off of my exam or studying, but no entry level person would just know. It was almost purely facts about services like nuanced rules about them instead of scenario based or “which services would you use for building an application like this?” One asked me to list the types of private endpoints (not even what they do just name them) and another asked for how many IPs were in a /24 block. I would’ve known these if I was still studying but I don’t just have this knowledge retained all the time without being in an engineering role.

And the live coding problems weren’t even that challenging. I knew “oh I need to use the join method for this one or a for loop for this one” but to not be able to look up docs or google was kinda ridiculous. My syntax ended up being off slightly and I fumbled through them for 15-20 minutes awkwardly until I gave up.

Anyway, I’m sorry I just needed to vent. I feel absolutely humiliated after it and I’m still reeling a few days later. My confidence is ruined and I’m questioning whether this was a fair interview.

Nomad/Consul integration doubts

Hi!
I'm trying to create a Consul+Nomad cluster, across multiple VPSs and physical hosts (using tailscale), and i have a few doubts on how to setup the integration between Consul and Nomad..

Actually i've followed the consul and nomad reference architecture described here (https://developer.hashicorp.com/consul/tutorials/production-deploy/reference-architecture) and then installed 3 Nomad servers, 3 consul servers and as many clients.

So i have something that looks like this:

- A -> Nomad server + consul server
- B -> Nomad server + consul server
- C -> Nomad server + consul server
- D -> Nomad client + consul client
- E -> Nomad client + consul client
- F -> Nomad client + consul client

Each of them is listening on the tailscale0 interface

(I also did this because the A,B,C hosts are more powerful)

But now, when i need to connect nomad to consul (using this config block : https://developer.hashicorp.com/nomad/docs/configuration/consul), how should i do it?
The documentation warns about that:

Nomad agents should be configured to talk to Consul agents and not Consul servers. If you are observing flapping services, you may have multiple Nomad agents talking to the same Consul agent

So How can i do that? Am i missing something?

Cheap WebApp Hosting with (huge) Database?

Hello,

new to creating hosted applications. I've been looking into Azure and AWS and i am completely overwhelmed on all the different services/products.

Hopefully someone here can help me find a good and cheap product for my needs...

I want to host an API which talks to a SQL database. The culprit is, the database is HUGE. One table of static data and about 100million rows which nets to something between 50 and 100GB. (I have no real control over the data, it is already the minimal amount i can go with).

My prefered approach would be the Azure WebApp/Database Combo but when creating i did not find any specific costs that would result with that sizes (as i just created the blank services) but i am afraid that is going to be expensive because the basic tier already charged me 1$ for a day of running that empty service.

I don't expect a lot load either - i highly doubt there will be more than 50 users concurrently and each user usually only queries once every few seconds.

Are there any cheaper ways to do bring that online? As this is a hobby project i won't make any money out of it and i don't want to spent a lot for that either...

If i missed something, please let me know and i provide more information :)

What strategies do you use for cloud permissions?

I know the basics:

* least privilege

* groups over individuals

* temporary roles over users

* remembering to grant bucket_name AND bucket_name/*
(Okay, that one still trips me up half the time).

But what other strategies are there? I'm especially interested in hearing how one manages S3 bucket access, because once you have a dozen teams and 300+ buckets it becomes a bit challenging.

Which is generally more cost-effective: running stuff on your infrastructure (cloud) or using a paid service API for that stuff

I'm planning to implement STT (Speech-to-Text) on my application and decided to use OpenAI Whisper. Apparently, it is an OSS and you could use the software even without the use of OpenAI API. OpenAI API for Whisper costs around $0.006 / minute which seems to be super expensive. I'm planning to use its OSS version and just run stuff in my own infrastructure in cloud. I'm planning to deploy it in AWS Lambda.

Given the context, which approach would be more cost-effective?

Track Code Efficiency during Development

Hello guys,

I am thinking about ways how to optimize code quality/efficiency during development. For instance, I want to know the number of invocation a certain function/method or how many (external) API/database calls a function is doing.

I know that tracing solutions like Jaeger (OTEL instrumentalization) empowers that kind of visibility, but I was wondering if that could be done without instrumenting the application code. The goal is to optimize efficiency during development phase ( code is not even deployed to any environment) in order to avoid higher cloud costs sparked by inefficient algorithms.

Are there any (open-source) tools out there, which enables that kind of visibility without instrumentalization? I am working with VS Code server in a k8s environment (remote development container).
