learning path: how to continue

Im kinda new in IT, mostly in DevOps. Since last summer, Im working as DevOps engineer, before that, I was QA engineer for 2 years.
I use a lot of things, like zabbix, VMware, Azure, Cisco IOS, (python, bash, powershell scripting) etc, but zero docker and container. You would say, its SysAdmin.

I wanna make plan to the future.
-learn Docker/k8s and become DevOps engineer without any specialisation
-learn security, like AppSec, and go for DevSecOps, or just security engineer
-learn Azure and become Azure DevOps engineer

Which one would you choose, and why?

I started to learn CKA, AZ900, CCNA, Comptia sec+. They are all basic stuffs

New job with complex infrastructure - How do you approach?

I have been offered a (contract) job today, with a large multinational investment bank. (I suppose it would be hard to find an investment bank that isn't multinational! - but anyway) that is looking to modernise their Devops processes

They have a large complex infrastructure, and a considerable number of applications. Part of my job will be to decipher a lot of it and come up with strategies to achieve their goals.

At this point I don't know how organised / chaotic it will be, but I'm curious what approach you lot take when landing on such a site.

Do you have a process to bring yourself up to speed quickly? Any hints / tips / etc

(My previous experience has been mostly with startups so I've built everything that existed)

"2022" CI/CD design

Let's say you are in a situation where your CI pipeline unit tests the code, has docker containers built and you have helm charts built and published.

How would you design the rest of the pipeline to make sure your CD pipeline can deploy to multiple environments, including production as soon as a developer merges to master.

It will be interesting to see how the landscape has changed over the last few years.

Need Some Advice For My New Role As Junior DevOps Engineer

Hi. So I've been working as a developer for about a year and a half (I graduated last fall). I am starting a new DevOps position soon and I'd be lying if i said i wasn't nervous. As it's a junior position I'll be learning a lot on the job. It's just that since I have no real life experience with DevOps (except for working with AWS cloud, Jenkins and overseeing builds and deployments), I am nervous.

I know I'll actually get a taste of the job while I'm on it and slowly get my hands dirty but does anybody have any advice for me?

Rsync with Jenkins

Hi there,

I’m currently facing an issue with Rsync & symlink that throws a ‘file exists’ error. After rerunning the Jenkins job it works for some magical reason. And in my source code the symlink removes the files and re-links them if found so there’s no issue there.

Does anyone know where should I at least start?

GitHub actions workflow updating file in different repo, trouble keeping things in sync.

We have a GA workflow triggered on push, which will build a docker image and deploy it to ECR.

This workflow will update a k8s deployment file( image tag. This is in a separate repo where all K8s files are stored) which then triggers ArgoCD to deploy the changes.

However a potential issue emerges when multuple workflows are triggered simultaneously.

Eg imagine that 2 commits are pushed to the source code repo at the same time.

The image version is 1.2 before hand

Workflow A increments the version to 1.3

Workflow B also increments the version to 1.3

The version in the K8s deployment will be 1.3, however it should be 1.4.

Is there a better way to do this?

Is 80% of what you do at a large company just navigating how to get things done in the organization?

I swear if all we had to do was create dockerfiles, CICD pipelines, and helm charts to deploy people's code, it would be easy, but we spend 80% of the time working around firewall rules, company proxy ssl certs, submitting jira tickets, backlog grooming, planning poker, security patching and regular meetings to get other departments to make simple changes, like adding a dns record or upgrading a ruby gem.

Is this normal devops work in a large organization?

Most stories I develop against have the requirements changed multiple times during sprint.. is this normal?

I'm pulling my hair out here.. I receive the problem in the story, and then my solution is coded to spec. Once I get into my PR review it's then decided there's "x,y,z" ways better/more optimal ways to perform these various tasks.

I mean I get there is typically more than one way to solve a problem, but this seems out of the ordinary versus my past positions I've held. Typically, if you have a working solution, and all tests pass you're all set.

Is the point of Agile to move fast, and push out features, and then create a backlog of stories to potentially optimize in the future?

Investigating DevOps and the role of a DevOps Engineer - What are the best sources of research?

Howdy,

I have been tasked by senior management to spend some time learning more about DevOps (as a topic) and DevOps engineering. It was suggested that I get a copy of 'The DevOps Handbook' and begin my research with this book. Is this a definitive source? Are there other sources you can share to further my education and understanding of DevOps and how to implement within existing teams (development, IT, Support, Sales, etc)?


Thanks in advance for the help!

Is the Vault Development tier more than enough for 1 production environment + 2 UAT?

Is the Vault Development tier more than enough for 2 Production Kubernetes clusters + 2 UAT Kubernetes clusters?

I seem to be missing something here, but with using Vault + Terraform, the Development tier pricing for Vault is more than enough for several environments. After all the only time we'll be interacting with Vault is when we are updating our clusters through terraform.

Or will the Kubernetes cluster itself connect to Vault every time it needs to access a deployed secret?

Going to full in into AWS or become 50% 50% among AWS and Azure

I have started looking for a position in DevOps, and I already passed the AWS Developer Associate certificate, but I was kind of thinking about where to go next - should I go my way with AWS and pass DevOps certification (to get a hand on CodeBuild, CodeDeploy, CodePipeline, ECS) or should I go and start also working with Azure? The main thing why I'm asking this - is as I have seen many positions asking specifically for Azure knowledge , therefore by getting practice with Azure I could also look for this position
