Questions about Devops learning with Django and costs.

Hey everyone,

I am a sysadmin who wants to slowly move closer to the Devops world and I have been researching best ways to learn. I have an old Django application that I used to host on a linux wm running on digital ocean. I abandoned that project a while ago, but I would like to redeploy it and also use this as a learning opportunity for the Devops world.

Many of these techonologies can probably be considered overkill for my small personal project, but this is simply for me to learn enterprise level Devops stuff.

So here is what I roughly think I would like to setup:

\- Dev and Prod environments created/destroyed with Terraform on AWS.

\- CI/CD pipelines.

\- Automated testing

\- Dockerizing the application and its possible dependencies.

\- Maybe even Kubernetes for orchestration.

I discovered this course on udemy and it seems to have almost everything, but the costs are too high to actually leave the project running after the project is completed:

https://www.udemy.com/course/devops-deployment-automation-terraform-aws-docker/

So is there any possibility to setup the tech stack that I want and also keep the costs somewhere in the 10-20 dollar a month range? I would like to actually leave this project running so to keep me motivated to actually finish it and make it good.

Thanks in advance!

Technology News

Hey guys, I’m a junior DevOps engineer and when I was interviewing I got the questions “where do you get your tech news?”. As a career changer and recent CS grad I didn’t (and still don’t) have an answer. I’m an up front guy and just told the interviewer I was working on it and mainly followed Reddit pages (lol).

So, I am still looking for some great places to stay up to date so I figured I’d ask the devops community, can anyone share where they go?

Fun fact: I didn’t get the job where I told them Reddit was my main source of tech news - could be related but I doubt it. Either way it’s funny.

Devops/Cloud vs Web3

Guys, what do y’all think about web3 ? Would it be a place for cloud/devops engineers, I’ve been thinking about this recently; cloud technology is basically the underlying infrastructure for web2 and there’s this worry I’m trying to break into a field that might already be going extinct.
Ps: I know this is a reddit sub but Iadded cloud tech for obvious reasons.

Those hiring devops people - do you typically require a technical test when hiring at a fairly senior level? If so, what form does it take?

Anyone else working at a senior level - what tests have you been required to take at interview?

Switching from DevOps to Solutions Architect...thoughts?

I've been in DevOps roles for 7-8 years now. I recently received a Solutions Architect offer from a great tech company (not FAANG but a tier or two below).

I'm tempted to take it but wanted to hear reasons why I shouldn't.

Why I'm considering it:

* My ceiling as a DevOps eng is quite low, I've never been the most technical or best eng compared to peers. I'll always have a job but it'll be at small no-name shops which has the accompanying smaller pay.

* I've failed a few interviews at similar companies for DevOps roles even after weeks-months of practicing, learning my mistakes, etc. Things like leetcode (which I've been asked) I've practiced but have struggled with even easy.

* Have always wanted to work for big tech - the speed, colleagues, and working on "sexy" products that my friends and family use has been a dream of mine.

* SA seems like a more defined path at other tech companies as well as leveling for promotions

* The generalist and big picture aspect of SA fits me well

Why I shouldn't take it:

* I could keep betting on myself - growing my eng skills to get a job at a similar company which will pay higher

* I don't think there's going back from this decision, I looked around on Linkedin and hardly anyone goes from technical > SA > back to technical

Anyone here have experience working at Disney as SRE contractor?

What does their conversation rate to full time look like? How is their overall culture, etc. etc. I'm considering a contract-to-hire over there and want to know the details. Well aware of this incident but am wondering if maybe they've learned their lesson? I dunno just looking to get opinions on the subject of being a SRE at Disney. I feel like the name brand recognition alone might be worth it even if the contract just expires in 18 months without conversion to full time.

Nomad; load balancing with Traefik question

Hi all, we've started experimenting with a consul+nomad cluster on Hetzner cloud. Now comes the part where we want to expose our services to the outside world.

I've read up on https://learn.hashicorp.com/tutorials/nomad/load-balancing and https://learn.hashicorp.com/tutorials/nomad/load-balancing-traefik (Traefik is what we would like to use) but the most important details are missing or simply skipped over. Workload orchestration is new to me, so I'm missing context.

Question: When a Traefik reverse proxy is deployed to a nomad cluster (or any workload orchestration tool), where do I point the DNS records to? Traefik can in theory run on any of the worker nodes, so to a static IP address does not seem to make sense? Maybe we should use Hetzners Floating IPs or native Load balancer? Or should Traefik be bound to one specific client, but would that not introduce SPOF?

Additional questions w.r.t. the last tutorial link:

1. The tutorials mentions "https://<Your-Traefik-IP-address>:8081". What is "Your-Traefik-IP-address"? And from where is this reachable?
2. "curl https://traefik.service.consul:8080/myapp" - from where should this curl command be run? Locally (probably not)? From the host? From the running container deployed by nomad?
3. "If you would like to access Traefik from outside your cluster, you can set up a load balancer in your environment that maps to an active port [..\]". Wait, wat? Is Traefik not the load balancer? I think what is highlighted in blue is exactly what I need, but it does not make sense to me at all.

Completely clueless about DevOps but I'd like to learn the basics so I can have CI/CD for the front-end and back-end of a school project + a remote database

So far in school I have done programming projects where I basically just keep the source code on GitHub/GitLab (our school has GitLab but sometimes I just use GitHub) and then I keep locally running the backend and have a local database and locally run the front-end as well.

I would like to develop my DevOps skills because I have very little knowledge on how it works and how I can set it up. My goal is to at least have a deployment pipeline for both my front and back end of the full-stack project I'm currently doing for school, and to also have a remote database during development. This way I can score better on the project but I also like the idea of just having some version of the app available for the client to view and to show my professors at an instant.

I just have no clue where to start and what kind of architecture I need to think about to achieve this. I only know vague things like the buzzwords; Docker? Kubernetes? AWS? I just have no clue what is what and where to start.

wiki of software builds and release process

Hi, as automation person, i come across the various software builds (.net or java, node, android, sharepoint or what so ever) and deployments. And difficult task at first is to understand the build and release process. Wish there are a wiki for explaining in brief about the build steps/tools as well as deploying those. Googling does not work like say Node/NPM tutorial then its about whole node not just about the build and deploy. Please post links/resources if you have.

What's at the top of the salary mountain?

Senior SRE here with 5 years in the industry. In the EU I'm making ~130,000 EUR a year. It doesn't look like I can go any higher in the "DevOps track" unless I move to the US. Is this the top of the mountain?

Where do Senior DevOps/SRE people tend to move from here?

Developer access workflow

I work on a lot of projects that interface with the AWS API, getting info mostly on EC2 and S3, but random asks come up here and there which require me to get access to different API endpoints from various roles across disparate accounts.

The devops team at my company is very short staffed right now, so requesting aws api permissions takes longer than usual lately, and most of that time is just sitting in the queue rather than being worked on. It seems like a lower tier security person could approve these rather than having devops engineers have to approve everything.

What workflow do you have in your org for getting these permissions approved?

I thought a good tool would be something that converts a yaml or json document into a set of permissions (running the underlying API calls). The developer who WANTS the permissions could just create the document that describes the permissions needed, then either pushes to some git repo (which helps with accountability) or some other process to get approved. Then, the devops resource can simply approve/deny rather than having the ticket sit in Jira un-approved while no work is done on it and Devops works on my valuable uses of their time

Database Image as a service. What do you think?

Been thinking about it lately. What if there's lightweight portable database image like Docker image where you have datasets you want- queries and procedures already created/stored. This creates consistency in data state between two users- use case: testing/ doing demos with customers. What do you think?

How do you manage parallel releases in one environment?

So I am currently working for a customer, they are setting up their contact centres. The contact centres consists of Amazon Connect and the configuration for its Lambdas and DynamoDB. They have parallel releases for deployment - like first release could include payments, another releases includes loans queues etc. Could anyone share any tips and tricks to manage parallel releases in one env(one AWS Account)

Observations on using PowerShell scripts in Azure pipelines

And, in today's "Nerds of the World, Unite!" corner: PowerShell syntax sucks. I can't think of enough bad things to say about it.

It's so bad, it makes Linux shell script look like plainspoken English.
