How common is it for someone to get into DevOps engineering without having prior swe experience?

Hello all, I currently work as a SOC analyst. In my free time, I've gotten a good handle on python and I'll be sitting for my AWS SAA cert test soon. I either plan on getting more certs or devoting time to getting proficient with the Linux terminal and looking into containerization tooling after I pass that cert. I'm curious if it is worth eventually applying for junior devops positions when I'm ready or if I should try for something like a cloud engineer or some sort of swe position first. It seems a lot of job postings ask for prior swe experience(understandably) and I wanted to get some advice on what path I should take or what I should consider. thanks!

how do you handle ssh host keys between image creation and deployment

I am creating vsphere VM template using Packer. Towards the end I remove ssh host keys to make pristine template - the idea being that when I deploy a VM from this template, I'll create new host keys.

I am then using Terraform to clone the template but Terraform cannot connect to the deployed VM because SSH is not running (because it does not have ssh host keys).

How do you solve this? Do you just leave the host keys in the template and then rotate them after Terraform deploys the VM?

Is there any point in using Release Pipelines in AzureDevops in 2022 for a New Project?

They seem to be remnant of the old VSTS artifact that ADO has morphed out of. Is there any practical reason a new project would incorporate these into their devops practices, as opposed to sticking to 100% YAML based pipelines.

Solutions for passing user specific data in to a container at startup

I'm looking for opinions on the best way to tackle a problem.

We have a web application that is span up as a container as a user logs in. To support some features such as 3rd party addons, we require certain preferences be available in file format inside the container in specific locations (Locations change depending on the addon). Has anyone had to tackle this issue themselves, and what did you find most efficient?

We work almost exclusively in AWS if that is a factor.

Junior SRE tasks (or something similair)

Hi all,

so, I'm looking to get into SRE and I know that there are many tutorials and books to read and stuff to do - but that's not what I'm after.

What I want to learn is what are your daily tasks on average; eg. if someone is to learn a programming language, I can tell them to go ahead and develop a calculator app or a simple CRUD web app for managing blog posts etc.

How would that translate to SRE engineer? What is something that you have to know in order to be be a junior SRE? And where can you practice that?

Taking myself for example - I would guess that I need to be able to set up a VPS over at Hetzner or DO, install an operating system on it, set up a web server and a mail server, secure it, set up some kind of monitoring for any outages... what else woould you add?

Recommended devops training ?

Just got off a call with the team and this year the company is allowing us to attend any trainings(devops related) to up skill.

Could be cloud related, ansible, terraform etc. Could anyone recommend something which they found real value in, that perhaps was a little costly but worth the investment. I have a few ideas of my own but since I don’t know it all, I was hoping for some community input.

TIA

Edit : I am a junior

Using artifactory for Minecraft plugins

Hi r/devops,

I own a open-source network of Minecraft servers running behind a Bungeecord/Proxy on a dedicated Ubuntu server. The servers are running from the Pterodactyl panel which makes each server running in a container with sftp access and much more.

I have just recently finished our pipeline in Github. We have a Live branch to represent what is on the real server and a Dev branch that we use as a local development environment that runs in Docker from VSCode. We create branches from Dev with an issue and create PR when they are ready to be merged into Dev, when accepted the changed files will also be pushed to Live branch and be deployed on the corresponding server using sftp in Github Actions.

The problem is NOT automating the download of plugins, there are projects for that.

When we want to update a plugin we download it from it's source and upload the .jar directly to the real servers. Instead, we want to update plugins from our dev environment so we can test if it works, where it would be efficient if we only put the updated plugin in one place to update all servers if possible.

If a branch is updating plugins and the PR have been accepted, the plugins should be deployed to the servers that use it, just like our config files are being deployed with sftp.

I have setup Docker containers of both JFrog Artifactory OSS and Sonatype Nexus on our Ubuntu.

I'm still learning about artifactories but I assume that's what I need here as the plugins are Java binaries. I have an idea of using Gradle inside each server to tell which plugin and version it uses, and by this file, Git can tell if a plugin have been updated.

APM/OTel product of choice?

What's everyone's current favorite APM provider of choice using OpenTelemetry?

Jaeger seems a bit lackluster these days. SigNoz seems cool. Grafana seems convenient. Kiali means I need to deal with Istio.

HA Vault backend

Hey everyone. I’m wondering the difference between Consul and DynamoDB as a backend for production Vault (community version)

Just some context:
My team is heavily invested into AWS

So I was wondering if there was any benefits, other than just being supported by Hashicorps, of using Consul, or if you all think I should just use DynamoDB or if DynamoDB has any drawbacks I wasn’t aware of.

Thank you all so much!

Understanding the backend of a callcenter

I’ve started studying coding and at same time work at a callcenter where we receive calls from customers. I’d like to understand something as I’m a noobie. Sometimes happens, a kind of a bug, where the customer calls, and on waiting line it appears 3 or 4 times the same number, like 000418229201. This phone number appears 4x and pending line to be attended. Just 1 of them is where the customer is really waiting to be attended. The other 3 line calls are “ghost” where when I attend them no one answer, because customer is on another pending line, but with the same phone number. Problem with a server?

How are applications using database providers like Supabase and Planetscale in production?

It’s always been drilled into me that it’s essential that any production database isn’t publicly available. DB PaaS providers like the above don’t have any facility for VPC peering and each database has a public IP.

Not sure if I’m missing something but how can these providers be realistically used in any serious applications?

CircleCI Security Incident

If you use CircleCI, and haven't rotated your secrets yet, you should do it ASAP.

I work with mainly RedHat and Fedora containers, which would be the better solution? Not a lot of info from quick googling on a comparison between the two.

AWS Multi Region architecture without API Gateway

Hey guys ~

I’m looking to make my current architecture multi-region. I’ve read a little bit about options, but it seems like every stack involves Route 53 & API Gateway. My current stack does not involve any endpoints. What I currently have are multiple lambdas, ec2 instances, and a few databases. Aurora global db is obvious, but for ec2 & the lambdas, I’m a little confused on which direction to go.

For example, in the event of an outage in us-west-2, how would my lambdas in us-east-1 know there’s an outage and to failover? Again, makes sense using Route53 / api gateway, but I don’t have any endpoints.

Thoughts? Let me know if I should elaborate.

Mac or Windows

I’m an associate DevOps engineer and I work on a team that is mixed mac and windows computers. The other DevOps engineer works with a Mac, and he’s making a gentle push for me to switch over. He says in future jobs, being able to work proficiently with mac would be a better selling point. I understand I haven’t gone into detail about the work we’re doing or the tech stack, so I’m just looking for face value, general feedback.

I think typically this might be posted somewhere else, but since we’re mostly devops folks, what’s your experience in this debate?
