Manually Configuring in Chef Nodes

How would you manually configure a chef node? (Say you wanted to add a file or delete a file manually) Do you use some sort of knife utility to enter into the node, or do you just SSH into the node like you would any other server? What is the best practice?

Service Registry/DNS Recommendations

We are building a new environment where different versions of various services will be deployed. When a request comes in to ServiceA, it will be routed to a particular version based on an HTTP header specifying the version.

Our services are currently deployed to AWS Elastic Container Service. We probably want to continue that but we could go in a different direction.

Right now, we are thinking that we want to use DNS. When a new version of a service (with for example version 12345) is deployed, it registers itself with the DNS server at 12345-service.example.com to be distinct from an existing service (for example abcde-service.example.com). Then a request specifies 12345 or abcde in a header and Nginx (or perhaps some other tech) routes the request appropriately.

I would use some flavor of AWS load balancing (the APIs are pretty good) except that we would like developers to be able to deploy this system locally using Docker.

Any suggestions as to a container deployable DNS server that allows registering/unregistering via API? Any other thoughts or suggestions?

Thanks in advance.

How do I use "-dev" similar to "-SNAPSHOT" in Jfrog Artifactory for gradle artifacts.

I'm new to this so please excuse the dumbness in this post.
I'm publishing gradle artifacts with version "-dev" to Jfrog artifactory, I need this to behave similar to "-SNAPSHOT" but it doesn't seem to do so. Jfrog Artifactory appends a timestamp to "-SNAPSHOT" versions but not "-dev" versions. Please refer to the screenshots attached for more clarity: https://imgur.com/a/Cz89wq1

This is the relevant layout settings for my repository:
Folder Integration Revision RegExp: SNAPSHOT|dev

File Integration Revision RegExp: SNAPSHOT|dev|(?:(?:\\d{8}.\\d{6})-(?:\\d+))

How do I achieve the same for "-dev"?
Is my approach wrong? Any input is appreciated.

Team retrospective sessions for DevOps

More recently I've become responsible for organizing my team's retrospective sessions and I was wondering if there were any thoughts and experiences from the community on whether retrospective sessions are as useful for DevOps/SRE teams as they are for purely development oriented teams and what formats have you either been a part of or applied in your own team that you feel has worked.

Historically we used pretty much the same templates as the dev teams used which was basically a run through stuff done/stuff coming up and then a post-it style board with 4 sections - what went well, what went wrong, things to improve and appreciations. I think I feel that's a bit stale and could do with something either more engaging or more interesting, though I think there's clearly value in look at the what are we proud of having completed/what did we fudge up categories.

Curious to hear other experiences and opinions

What are some great platforms to help implement devops practices?

Never used one but i have a feeling there are platforms that can be used to define pipelines / workflows for infrastructure provisioning, configuration management and more that are both operations and developers friendly.

For example, developers could use that platform to provision on demand environments after that pipeline / workflow was configured. That workflow will connect to defined secret and configuration management system, provision new kubernetes environment for developer, connect to helm repository and deploy all applications and create + provide dns record for that new environment.

Platform that will allow for one place to provision everything and monitor status of all that is provisioned.

Maybe help with blue / green or canary releases.

Are there good platforms like this that worth checking out?

We're running on kubernetes (GKE/EKS...), using helm, terraform and planning to introduce argo project.

From Head of Technology to Head of Infra

Hello r/devops !

I need some help from the seasoned folks around y'all

I've started my career as a developer, went all through the hoops until I landed as Head of Technology in a medium sized company

In this role I was overlooking everything from product, dev, infra, 3rd parties integration etc etc

I've also had some surface-level hands on experience with clouds (mostly spinning VMs and configuring GWs/FWs)

I was recently offered a Head of Infrastructure role in a large (think Fortune 500 large) company,

While I understand the basic terminology and I have a rather good grasp on architecture, I've never dealt with such scales.

Here's where you come in -

Any resources, any blogs, podcasts, books, YouTube channels and the likes you can recommend I consume before stepping into the role.

Anything and everything goes, my goal is to study as much as possible without a specific focus before I begin.

Thank you

Why Kubernates instead of PaaS?

I really don't see the benefit unless very specific use cases. Specially for any company below corporation level. Why not just use PaaS (EC2 / Azure App Service)? They manage themselves. They auto-scale. They can be maintained by a trained monkey. CI/CD is very simple to setup.

Why are people instead choosing to host their solutions in Kubernates? Hosting costs of PaaS can't be the reason, since having to hire a DevOps Eng to maintain your infrastructure is way more expensive than any PaaS out there.

What am I missing?

Infrastructure and Security

Hey devops, I’ve been a SWE for 5 years and have worked on individual pieces of infrastructure or application level code in various capacities and trying to wrap my head around everything fitting together better.

As a learning experience / future showcase for projects I am building a blog (woo 1 more to the list). It will have a frontend hosted on s3, a backend returning some data. Route53 dns will point to s3 making api calls and rendering html. I have my api service containerized with a port exposed mapping to the api running. The api has some endpoints with no request authentication and some using oauth2 session (1 day expiring) flow. I want to put nginx running in a seperate EC2 to sit between api and frontend but wasn’t sure if this added any level of security since the instances are still technically public if anyone visited the exact ip. I setup nginx with ssl. I am led to believe this is overkill if users won’t be signing into the site.


Overall a question about security and the roles each pieces plays in completing the puzzle. Thanks for reading.

what questions were asked to you in your interview for Devops role?

Share the questions (whatever you remember) maybe tools wise of possible. I know this is a big ask but if we look at the number of people are here in the sub, this thread could be a reference to all the future aspirants to devops role and not waste time on YouTube videos on devops interview questions. You can also suggest channels which are genuine to check for interview preparation for Devops role. Thank you

I'm completing my Bachelors' in Aug 2023 and I want Devops to be my first job.

I'm currently starting my final semesters of my Bachelors' degree, I'm already a Devops Intern at a startup with a stipend of 242USD per month (I feel very underpaid), and I literally can not find any viable job openings for a fresher like me which does not have 3+ years of relevant work experience.


I want to know how a fresher can get started in Devops in 2023. I've worked on a lot of things, from pipelines to kubernetes, docker to VMs, serverless, NoSQL, cost optimization, server administration, I've worked on a lot of projects, made reports, case studies, brought up multiple solutions to a problem and moulded my work as per the client's needs.

​

I understand how the role of Devops requires experience. But how can I have experience when there is no place to begin from? I do not like development, yet I can write up lambda functions, work the backend and on APIs, I can write scripts and automate as well. I love distributed computing, I love cloud and I love devops. I want a career in it. But how do I even start?


I apologize if the post comes off more like a vent, but I could genuinely use some guidance and advices. Please reddit, do your magic.

Explain Why Kubernetes and Containers are Better Than VMs Like I'm 5.

We run a large monolithic ASP.NET (ported it ASP.NET Core from full framework) web app on AWS Elastic Beanstalk and it's been working pretty well for us. Deployment times are pretty slow (we use rolling updates) and AMI upgrades and beanstalk system upgrades sometime cause issues with our eb extensions, but it's fixable and well understood by now. I know containers and Kubernetes is the new standard in cloud deployment, but I'm struggling to grasp the benefits of using it versus an auto scaling cluster of VMs. I heard Kubernetes is complex and requires some expertise to run. At the same time, Beanstalk is pretty user friendly on the surface.

Working using a in-house tool at early career stage

Background-
Hello, Junior DevOps Engineer here ( atleast by profile name ) and I have been using only an inhouse platform tool for infra provisioning since the start of my career ( aug, 2021 )
I do use various other tools and tech aswell in my day job ( jenkins, AWS, nexus, git etc ) but my majority of my work is using a inhouse framework that uses terraGrunt for infra provisioning and it has the end product are K8s pods which run the infra ( there is a lot of things in between but it’s all learned from the platform team and not researched by me ) been like this in my 1.5 years exp.

Question - Is it good for my career and upskilling in long term ( I’m 23 years old) to be using this tool for so long and also going forward or is it not a good thing for a newbie.
Out of all the things I do, I’m best at running this tool.


PS. Sorry for my english, it’s my second language
