Seeking Guidance: Preparing for DevOps Internship in 15 Days

Hello r/devops community,

I recently secured a DevOps internship at a startup, and I have 15 days before it begins. I prepared for the interview in just 2 days, focusing mainly on theoretical concepts to clear it. Now, I want to utilize the remaining time effectively to get ready for the actual work.



Could you please advise on:

\- Key areas I should focus on to build a strong foundation?

\- Essential tools and technologies to learn?

\- Any beginner-friendly projects or resources to gain hands-on experience?



I appreciate any guidance or suggestions you can provide to help me make the most of this time.



Thank you!

Just finished Class 12 – Is DevOps a good career choice?

Hi everyone,
I’ve just completed Class 12 (Science with Computer) and I have a lot of free time right now. I recently came across DevOps and I find it really interesting. I want to know from people who are already in this field – how is your experience with DevOps so far?

Is DevOps a good option to build a career in? How is the future of this field, especially in terms of learning curve, job demand, and salary?
Also, since I’m starting fresh, do you think this is the best path to go for, or are there other tech fields that are better or more rewarding than DevOps?

Would love to hear your thoughts and experiences. Thanks in advance!

A step back

Hey guys
Hope you’re doing well

I’m seeking advice, regarding my next mission


I’m working in a consulting company, I’ve been in a mission as a DevOps (4years) it was my first mission ever, so I had a good understanding, and practices regarding DevOps and cloud

My mission came to an end recently, and my company gave me a new one ( but it’s more for backend development, with JAVA) I donno if it’s a good move to take it, as it will show me a side am not very familiar with, or would it mean that I’ll be stepping back from DevOps ?

I’ve been thinking about it a lot lately but can’t make up my mind.. any advice from you guys or similar experience is very appreciated

Thank you all 🙏

What’s something you thought you needed to learn—but never actually used?

When I first got into cloud and DevOps, I felt like I had to learn everything.

I remember spending weeks going deep into Kubernetes.....thinking it was “essential”.......only to land a role where we just used ECS with some simple Fargate configs. Never touched K8s once. 😅

It wasn’t a total waste, but I definitely overprepared for stuff that never came up.

Curious how it’s been for others:

What’s one tool, framework, or concept you went all-in on… that ended up being irrelevant in your actual work?

Or the opposite.....what’s something you ignored early on, but later realized you should’ve learned sooner?

Let’s trade war stories.

Is it plausible to get a job in this field without experience/degree?

Hello everyone,
this question has been bothering me for quite a while now.

I am 25 years old and have never focused on one career path (I basically threw my education away until 18, and then had to gradually complete my high school diploma while fully working a “starting job” call center employee), so when I turned 24 I had the opportunity to take a paid-for full DevOps course of about 1 year.
Through the course I learned (more like dabbled in) every aspect a DevOps person might need (Git, Python+Java, Kubernetes, SQL, Linux, AWS … etc ), and now I am expected to find a job in this field.

Problem is, all the job posts on Linkedin and on job posts sites for entry-level jobs specifically require a degree in computer science (or a similar field like software architecture), and at least 2 years of working in prior company experience (varying but the 2 years is the lowest I’ve seen).

Bottom line is, is there any chance I might get a job in this field without the mentioned above requirements? It all seems like a “chicken and the egg” situation, like how am I to gain experience if no one will hire me? Also to get a degree in the mentioned fields is very hard and expensive, not something that is in my ability, money-wise and being smart-wise.

I just want to know if to keep on trying to apply and get a job if the road is blocked already, or change course entirely to not waste my time.

Would like to hear some of your experiences and maybe a tip or two if you have to share with me…

Thank you all for reading!

Twilio Manager: A Python-Based CLI for Managing Your Twilio Account

Hey Reddit!

I’m excited to share my new Python CLI tool, Twilio Manager. Built in just 3 days using AI helpers (OpenHands, Claude, ChatGPT), this wrapper around the Twilio SDK lets you:

Send and view SMS/MMS messages
Place and manage voice calls
Inspect your Twilio subaccounts, balance, usage, and more

🚀 Features

📞 Phone Number Management
Find available numbers (by country, area code, capabilities)
Purchase or release numbers
Configure voice/SMS/webhook settings for each number
✉️ Messaging
Send SMS or MMS via a simple command
Fetch message history (inbound/outbound)
View delivery status, timestamps, and message logs
📱 Call Control
Initiate calls from CLI (with specified “From” and “To” numbers + TwiML URL)
View past call logs, durations, statuses, and recordings
Manage call forwarding, SIP endpoints, and call recording settings
💼 Account Insights
List all subaccounts under your master account
Check your current balance, usage records, and pricing details

⚙️ Modular Design & AI-Powered Scaffolding
Each CLI command maps directly to a Twilio REST API endpoint for maximum flexibility
Built-in helper templates for quickly generating TwiML snippets or phone number configurations
Designed to be easily extended: drop in new commands or customize existing ones

🤔 Why I Built This

I wanted a scriptable, no-GUI way to manage everything in Twilio—from provisioning phone numbers to sending quick SMS alerts—without opening a web browser or writing repetitive boilerplate code. Using AI helpers (OpenHands, Claude, ChatGPT), I was able to prototype and ship a working CLI in just 3 days. Since then, I’ve been iterating on it to make it more robust and user-friendly.

update-action-pins -- a simple CLI tool for updating pinned action versions in your Github Action workflows from tags to SHAs

https://github.com/Skipants/update-action-pins

Hi everyone!

In light of the tj-actions supply chain attack (https://nvd.nist.gov/vuln/detail/cve-2025-30066) I recently made this simple executable that updates referenced Github Actions in your workflow files to use commit SHAs to pin the version instead of the tag name or branch.

I found it real tedious to go through each referenced action, go to its repository, find the SHA the tag corresponds to, and then update it in our workflows. This tool alleviates that.

I thought it would be useful to everyone else so I open-sourced it and advertised it here.

I am also willing to support the tool in the near-long-term.

Let me know if it helps (or doesn't) and don't be afraid to post an issue on the repo if you find any bugs.

Cheers!

General Security Pipeline

Hello,

I'm in a neighboring field (software engineering) and have been tasked with some initial research about building a security pipeline to build and ship software that runs on a customers network. All of the pipelines I have ever built are for internal products, never for something a customer would run.

Our clients are highly motivated to adopt the software, but only if they care verify it comes from a secure source.

From my initial research, the field of devsecops seems broad and I have recommended that company pursue a security engineer for this purpose; however, I need to do something in the short term.

What are the low hanging fruit of shipping secure software?

I'm initially looking at something that doesn't break the bank. I know the cost is proportional to the level of paranoia. What does a good security pipeline look like?

My initial recommendation is just:

\- Build in a clean env like aws CodeBuild
\- Syft Software Bill of Materials
\- Grype Security scanning
\- Cosign signing service
\- Load to s3 & distribute with cloudfront

Feels basic.

What do you guys do? I would love to hear some recommendations. I don't really know this field.

Thanks!

Request guidance from experts in the field

My current situation is unemployed. I have no university or professional degrees. I have internet, a laptop, and free time. I love computers and the internet very much and I am very good at using them. I can understand and learn quickly, and I saw that the field of DevOps might be suitable. I do not want to talk a lot. I want to start from today. What is my first step? All my love to all ❤️

Looking for cheapest way to run a 24/7 background process (PaaS preferred)

Hello everyone,

I'm looking for a reliable and low-cost way to run a continuously operating process that needs to stay up 24/7. It connects to a data source and records or processes data in real time. There is no event or trigger to kick it off; it just needs to run uninterrupted.

Ideally, I would like to use a PaaS (Heroku-style), but I am open to other solutions like VPS if the price and performance make more sense.

Requirements:

* Persistent background process that runs continuously
* Lowest possible monthly cost
* Language and runtime agnostic (can use Docker if needed)
* Minimal maintenance preferred but not a hard rule
* There will also need to be a user-facing web app or website alongside the process

So far I have looked into Fly.io, Render, Railway, Google Cloud Run, and Hetzner Cloud. While I have explored these options, I am still not sure which is best for my use case.

I would appreciate any recommendations or real-world experience with similar setups.

Thanks!

Considering CI/CD tools in preparation to launch my SaaS startup.

So I'm fairly familiar with CI/CD concepts and I'm a big Jira user so looking into Bamboo at the moment but curious if anyone has got any strong opinions on tools. I've had limited exposure to ADO.

Summary:

* LAMP stack, not a shred of Microsoft stuff or .Net
* Cloud native, purely on AWS, most infrastructure is IaCed
* Dev environment at the moment, preparing to built
* WebApp
* 3 WAFs (CDN, haProxy and internal) protecting against OWASP threats

Key aims:

* Want basic CI/CD to begin with, initial focus on automate buid/deploy (blue/green) and test
* Aiming towards feature toggling and telemetry
* Preparing to implement CIAM soon, probably via B2C or Okta
* Also want linting, code security scans (mainly OWASP) and identify dead code, manage library deprecation more proactively

I don't mind investing in decent tools but this is an extremely important decision for me so I'm keen to hear from people who've evaluated various tools and are very happy with their current choice.

Coping up with the developments of AI

Hey Guys,

How’s everyone thinking about upskilling in this world of generative AI?

I’ve seen some of them integrating small scripts with OpenAI APIs and doing cool stuff. But I’m curious. Is anyone here exploring the idea of building custom LLMs for their specific use cases?

Honestly, with everything happening in AI right now, I’m feeling a bit overwhelmed and even a little insecure about how potentially it can replace engineers.

Roast my resume again!!

Last time I posted to get feedback, lot of nice people. I am still not able to create the best resume without faking information. Need help!! This resume is still sub par.

https://ibb.co/k2cytfK4

https://ibb.co/hxbTbVb3

I do not have hands-on industry experience with below items in resume:
1. Kubernetes and Argo CD: Our leads are playing with setting up the cluster, but do not share access for that. I have learned kubernetes from kodecloud course and practise labs in udemy.

2. Jenkins : Same as kubernetes, we have free style pipelines written by the seniors and leads but refuse to share access in fear of becoming "obsolete". I have create multiple jenkins pipelines with my aws free tier account ec2 and local machine.


I really want to learn new technologies, methodologies given the opportunity but need to jump the ship first.

How does your team handle post-incident debugging and knowledge capture?

DevOps teams are great at building infra and observability, but how do you handle the messy part after an incident?

In my team, we’ve had recurring issues where the RCA exists... somewhere — Confluence, and Slack graveyard.

I'm collecting insights from engineers/teams on how post-mortems, debugging, and RCA knowledge actually work (or don’t) in fast-paced environments.

👉 https://forms.gle/x3RugHPC9QHkSnn67

If you’re in DevOps or SRE, I’d love to learn what works, what’s duct-taped, and what’s broken in your post-incident flow.

Load balancing multiple Rathole tunnels with Traefik HTTP and TCP routers

I wrote a continuation tutorial about exposing servers from your homelab using Rathole tunnels. This time, I explain how to add a Traefik load balancer (HTTP and TCP routers).

This can be very useful and practical to reuse the same VPS and Rathole container to expose many servers you have in your homelab, e.g., Raspberry Pis, PC servers, virtual machines, LXC containers, etc.

Code is included at the bottom of the article, you can get the load balancer up and running in 10 minutes.

Here is the link to the article:

https://nemanjamitic.com/blog/2025-05-29-traefik-load-balancer

Have you done something similar yourself, what do you think about this approach? I would love to hear your feedback.

Just put the API methods in the bag, bro

Early this year I got called back to the dev side after a decade doing infra. Basically a staffing incident recently left us without a lead dev and my name got pulled from the hat to fill in.

And the process has just reminded me how easy like 95% of modern development work is. Let me guess, we have to write CRUD methods for a new object type and shove it in the database. Oh, then the offline worker job has to call an API somewhere once a day for each row? Wow, how novel.

The best part is every time I add a new button to the app which turns some text from red to green, the business jerks me off like I've just invented gzip compression or something. Meanwhile on the infra side no one knows you exist until you're up Saturday morning at 2AM trying to find which asshole pushed an N+1 query on Friday.

Most of all it refreshed my perspective on why devs are so helpless any time they have to touch infrastructure. The scope of dev work is so narrow and context-independent that a verbatim solution probably already exists in 10,000 different stack overflow answers and just needs a find+replace. Now they even have a robot button in VSCode that does that for them.

Meanwhile for infra you get like two systems deep and already you're source-diving some golang repo on github just to figure out what shape of yaml object the system will actually accept. Or straceing a system component so old that Stallman himself might have written it, just to figure out which syscall it's been hanging on for the last hour. If you need help you'd better hope someone on the team has hair grayer than yours, otherwise you're completely out to sea. Because you sure as hell can't google the specific mixture of platform, provider, and runtime that makes up your infrastructure cocktail.

So the next time a dev says the pipeline is broken because they elected not to read the line that said "syntax error at shittycode.js line 69". Or opines on how the infrastructure is unstable because they sunk the database with a one-thousand line query that dodges every index you've ever set. Or suggests that devops is blocking their new paradigm-shifting code release (it adds a circular progress indicator) just because the dependency scanner is red.

Tell them "just put the API methods in the bag, bro."

how would one go about setting up CI/CD where multiple teams need to use the same resources to run there pipelines?

I am interviewing for a role at a company where they mentioned that they are running into issues where multiple teams want to use the CI/CD to run their pipelines as their workload is GPU bound which is a scarce resource. What would be a good strategy or process to setup for easier coordination between teams?

In my current role, I am responsible for CI/CD for my team and the workloads are not any particular resource intensive. Any help or pointers would be really helpful!
