What should you know before iac?

Getting started with Terraform,
What should I know before?

Is Ansible a better beginning point?

I’ve setup a Portainer that that runs Teleport… (really random probably mentioning that)

What should I be familiar with before Terraform?

VM?

Any experience on making the Datadog => Grafana Cloud transition?

Given the cost (especially on custom metrics), we're looking at alternatives to Datadog. I can't find anything comparing it against Grafana Cloud, like not even marketing fluff from Grafana.

Anyone have any experience making, or even just evaluating, the switch?

What are you charging hourly for DevOps work?

Thinking of doing freelance after a small hiatus, was previously charging around 150/hr for DevOps work and was curious what other contractors/freelancers are billing. I understand this depends on many factors but mostly will be doing deployments, dockerizing apps, hosting apps on clients AWS etc.

/r/DevOps - I'm calling on you to be the hero that users need right now and build a Lemmy instance for your favorite community.

With the shitshow that was the AMA today, it's clear that reddit will not be backing down on the API changes anytime soon, and even doubled down on a lot of really dumb stuff. This has prompted an escalation for many communities to make their blackout indefinite or permanent.

In doing this, we have an opportunity to show that community and federated solutions can work and that a community can come together to make change.

/r/DevOps has a unique ability to deliver socially impacting technologies to communities in need, and I think it's time that we act.


I'm doing this with /r/Tucson, and creating tucson.social as a lemmy instance. We are looking at making it a Public Benefits Corp with shareholders that are local to Tucson itself. We are also making an open code of conduct and site terms and conditions to give everyone a say in how it's run.


As I do this, I'll be making a github document detailing how all of this came together, how much it cost, and any technical issues that came up along the way.


I hope that others can be inspired to do similarly - it's the best chance we've got.

DevOps managers - tell me where I'm going wrong with my resume

https://imgur.com/a/f9Pykmq

I've worked this thing out over and over again. I can't see the forest for the trees anymore. I personally think my resume is to the point and digestible. No word salad, no long ass descriptions.

I'm currently at a startup that is not doing well financially (I haven't been paid in 3 months). I've been applying to roles that I believe are good fits for me, ie. they use similar tech stacks, my skill set would be very complimentary to them. But no bites. Just automated rejection email after automated rejection email. It's very frustrating. I really don't feel like ending up on the streets.

So, like.. what is so wrong about this resume? I'm totally at a loss. Be brutal if you must. It will be a good learning experience for me.

Trying to come up with a new Continuous Integration (CI) setup

Currently we are relying on a Jenkins based setup for our CI setups, we have a wrapper that was setup around Jenkins for consuming it. And for CD, we are using Flux (great tool).

The CI setup is very old school and tightly coupled with everything where when we cannot build artifacts and promote it into higher environments.

So I am trying to come up with a right strategy to design and build a new CI setup, hoping to decouple these Artifact building and fix the build promotional issues. Also trying to get rid of Jenkins for good.

Any references I can get here to implement the CI setups with my need?

Serverless and AI: How do you use it?

What was your experience in using serverless infra for AI/ML? How did you manage to resolve the cold start problem, timeouts and memory issues?

We tried building a whole NLP (natural language processing) system using AWS lambdas. And ran into a lot of problems in the training part. For more context you can read https://www.reddit.com/r/devops/comments/1452bfe/devops_startup_around_observability/

How versatile did the Apple Silicon chips have become now that they are getting ready to present the M3 later this year?

I know that at first there were some hiccups with Docker/Terraform and some probably unsolved issues with x86 architecture.

Is anyone using mac on a daily basis here? How versatile is it for a DevOps?

Server couldn't handle springboot

I am a server guy who deployed a springboot application on t2.medium. there are 3 major issues i am facing now.application is currently under development so no end users using it but the api calls are very slow. I checked the cpu and Ram but there's nothing unusual. Not only api calls are slow but i am also experiencing cors error even though cors is enabled in apache2.
Its not everytime I am experiencing cors error but it just happens randomly. 70% of the time it's fine but remaining 30% suddenly i am experiencing cors error when requesting.
Also not able to send sms. I set up a SMS provider to send sms via api key which works on local machine but doesn't on the server.
Idk why sms works on local machine but didn't on server. Any idea on these guys?

mTLS in 15 Minutes

Ok - if you're in devops you probably know this title is a lie. But, recently I had the opportunity to debug / help implement several mTLS connections and it all became much clearer to me. And as you might already realize, the hard part is actually the TLS part not the "mutual" part.

Anyway, I decided to take this opportunity to attempt to write down my illuminated understanding on the topic as clearly as possible - if not quite ELI5. :)

Anyway, I hope my fellow devops enthusiasts might find some valuable information in this post:

What suggestions would you give to a fresher?

I am a fresher and I have been working as DevOps engineer for past few months already, it will be one year in July. I have already mastered (at the fresher's level and still trying to improve) scripting in Python, Bash and Groovy. I am good at creating pipelines in jenkins and azure pipelines. I also have good hold on docker, jQuery, yQuery, terraform and azure cli commands. Well aware with the cloud services, especially GCP and Azure (and will be preparing for certifications soon). I didn't work much with Ansible much and since my organisation's product is yet not scalable on demand, I don't have working experience in Kubernetes, but I am well aware of both Ansible and Kubernetes. I'm also learning Go and networking.
Now, from here what will be your suggestions for me? I want to switch so that I could work from my hometown. What should I do?

How to do automated rollbacks if issues arise?

My experience is in microservice architecture with deployments on kubernetes on a smaller scale with fast forward merging and only one version of a service running. if another version is required, then we will create another service that's versioned so it's two separate service

​

But on a high volume cluster that's now how things would work. So if you're rolling out a SaaS product and later detect issues, what tools/techniques/strategies can be used to stabilize multiple deployments and versions? What if issues are only in a small section of deployments? Any readings would be great. How would you go about detecting these issues? Liveness/readiness probes are not sufficient
interested in what kind of architecture and setup is require to build a "robust" / self healing system

For those of you who are really good at problem solving, do you recommend any problem-solving books/videos?

I'd say I'm good at my job but I find that I sometimes spend too much time on a problem whereas certain people at my company at just very good at knowing what to do, look for, etc.

Beyond increasing your technical aptitude about something, are there any good problem-solving techniques or videos you recommend? Similar to what programmers do in terms of data structures and algorithms and finding the best way to code something.

How to Prepare for HashiCorp Certified Terraform Associate Certification (002)

The Hashicorp Terraform Associate certification is for Cloud Engineers specialising in operations, IT, or development who know the basic concepts and skills associated with open source HashiCorp Terraform.

People willing to get certified will be best prepared for this exam if they have professional experience using Terraform in production, but performing the exam objectives in a personal demo environment may also be sufficient.

The certified individual understands which enterprise features exist and what can and cannot be done using the open source offering. This is the only and official Terraform certificate so this creates a difference between certified and non certified individuals. So, let’s get started!

Validating product - a tool for database changes

Hey folks, we are two guys who just built an MVP of a CI tool for database schema changes. We really need your honest feedback.

Why: We always found it painful to make changes in database schemas. You always need to test schema changes manually across multiple stages. And if you run unit tests for your application code, it doesn’t cover the database changes properly.

What: The tool supports branching and unit testing that we were always missing elsewhere. The current version is a UI-based playground, a mini CI tool for you to play around with and test the basics. This is just to see if we're on the right track.

The goal is to create a full CI/CD tool to make all database changes super easy. The next step for us is releasing a CLI tool.

Link: https://hub.whizzer.io

Here's the stuff you can do right now:

create repositories and projects with schemas
branch your schemas
run unit tests
invite teammates and collaborate on the projects

Please share your feedback, and test the playground. Thank you! :)

Specialization for SRE, DevOps pursuing a Major and maybe a PhD

Hi,

Maybe I will get some advice from someone experienced in interesting fields. I'm experienced SRE, DevOps and earning good money in a big corporation. Besides that, sometimes I work as a consultant with Linux, AWS. I'm primarily working with AWS, databases, automation, and architecture, but I want to go into one specialization. Some people are good at firewalls, some at security, and some at one language. Sometimes I think I'm a Jack of all trades, a master of none. I'm finishing my major studies and want to achieve something more. Be an expert who can make a presentation and research for many years (not learning a new tool, a new AWS service every 1-2 years). Something that I'm good at is architecture and planning. That's what I'm currently doing. In the general cloud, it is distributed system, so I thought that maybe I should go into distributed file systems. It is something that can be interesting for me. I can combine security and privacy of data, architecture and cloud. According to Andrew S. Tanenbaum in the book "Operating Systems" it is a rapidly developing field .What do you think about it? Can it be something for someone with my role?Should I focus on something else? I don't know anyone with PhD in CS, so I don't know what I should think. How can I choose specialization? Is there a need for people that can plan some systems like that?
