Software Dev to Devops

I am thinking of getting a few certs to make a career change:

- RHCSA
- AWS certified Developer
- AWS Devops Engineer

I don’t have much experience in any of these areas and have a training center near by so I am thinking it couldn’t hurt. Would you include anything like VMware? Do you think certs hold value? Appreciate all opinions!

Is it just me, or do companies think DevOps engineers can solve all their problems

I've recently been looking at applying at companies to grow my career as a DevOps engineer.

I'm noticing that allot of companies don't seem to understand the role of a DevOps engineer or the culture of DevOps.

For example, they would list requirements that are not at all DevOps related and more security or network related, which in that case should they not just hire a network engineer ?

And regarding security, should they not then list the position as a DevSecOps engineer ?

Im getting really frustrated.

It almost feels that companies think if they have a issue they can't solve, they need to hire a DevOps engineer , since we are some type of magician that can solve all of their problems.

Is it just me thinking like this ?

Getting into DevOps

Hello,

I’m after some information that would help me get into the DevOps role as I unfortunately flunked out of my CS degree (final year) as I was not in a good situation.

Currently, I am in the “do everything from web dev, customer service, setup and configure networks, AD management, to backups, patch management for software and servers, AV endpoint management, incident response, Azure/365 admin, diagnose common problems with software, hardware and all three major OSes, hardware repair, random security related tasks and the list goes on” role at a small company for 1 year. (Don’t even know the title for my job would be)

I am working towards getting entry-level AWS certificates and RHCSA as I see them to be the best for getting my foot in the door (would prefer to be vendor agnostic with Linux), as well as playing with Git, Docker, Ansible, Terraform and K8s, while concurrently playing with Python, Golang and ML. Going to start with Jenkins soon. I have always been interested in the Pen testing role (also working towards OSCP), but am open to the wider InfoSec/CyberSec role.

Am based in the UK. Any suggestions on what I should do break into the space? Not many junior roles around me and worried that the lack of degree would close a lot of doors on me.

Thank you.

Development databases in Docker aren’t good enough

Hi r/devops,

Full disclosure - I'm a software engineer working on Spawn. We've put together this blog post to discuss why we think Docker falls short of giving you realistic and useful development database environments: https://medium.com/spawn-db/development-databases-in-docker-arent-good-enough-503ea95e7545

Your thoughts and opinions on this would be very welcome!

We've certainly felt the pain of using development database environments only to find out that our changes go wrong when they reach production. We built Spawn to try and make that pain go away by making it possible to instantly provision realistic production-like environments for Dev and CI workflows.

What is your opinion on Incident Management Tools

Hey Folks,


I am interested in what other teams are using for incident management tooling.
Are you rolling your own or using a SAAS provider such as Pagerduty / Splunk On Call (formerly Victorops) / Squadcast.
I am currently going down the journey of implementing a third party service to intelligently handle alert / event notification and routing.


From what I have seen so far a lot of the providers seem to have feature parity with the key difference coming down to price.

setting up a new environment in azure (beside the existing AD)

hey guys,

coming from google cloud, so azure is kind of new for me (and the company I joined as well)...

i want to setup a somehow separated cluster for k8s and create all the needed stuff like networks, etc. with terraform.

we already use office365 and the azure AD, but nothing else like VMs or DBs.

how can I avoid destroying the AD while creating my k8s stuff? no on in the company has knowledge about that, and I maybe google'd the wrong stuff.

can I just create a "project" like in google cloud (is that "Tennant" the proper equivalent thing for this?) or do I need to do something else?

Best,

dejeckehoot

Currently joined as a devops engineer

Its been few days since i joined as a devops engineer and i Have little/basic experience of 6 months from my previous job,

Currently i have been asked to look into their application stack and below is the stack,

Frontend: angular
Backend language: C#
Backend framework: .net core
Cloud: Azure, soon to be shifting to AWS
Database: postgresql
CI : jenkins

I have to shortly design and implement an architecture by myself which i am very excited and frightened at the same time to create three environments for test, demo and production with high availability and scalability.

This is how i am planning to implement on AWS as cloud provider,

Code > gitlab > jenkins > ansible > docker

The code will be pushed to gitlab and the code will be pulled automatically to jenkins to run a job via webhooks.

In Jenkins i need add a few ssh commands to push the build version to dockerhub with env variables and add a post build action towards ansible to run the deployment and service yaml scripts

Now i am stuck in thinking with three big questions

1) if i should use only docker and docker swarm to deploy the web application.

2) Or shall i use Kubernetes cluster in place of docker from above architecture stack for both containerization and orchestration.

3) this is my major stuck point, how the hell do i go about attaching the database to the web application if i am using docker or Kubernetes.

Please advise

Azure Devops installation

Hi all,

I would like to get Azure DevOps setup and was wondering if I need to install Git before I can use DevOps?

Thanks in advance.

Can you link to any videos which explain how a server farm backs up its data? It must be a very large amount of data to backup & I’d like to learn more about how it’s done.

Is it typically raid drives, on-site removables aka iron mountain, off-site using a wide pipe, etc.

What motivates you?

I became a devops engineer from developer and I feel I am no longer driven or motivated. As a developer I used to be excited to write code and create applications and now I feel my job is to run what others are writing. There is no true product innovation in that. Any thoughts or suggestions?

What's the typical markup rate by Randstad for a devops engineer position.

Hi,

I'm trying to figure out a typical markup rate by Randstad for a devops engineer position with 10 years of experience going through them to the client.

I know there are many unknown variables to consider but I'm generally trying to understand from their recruiting stand point on what's the lowest they can do.

Knowing that might give me a little perspective on quoting the contract rate while working Corp to Corp engagement.

Regards.

Terraform UI for non technical CLI users

I currently have a server build process that uses Terraform and deploys a server all from code.

I'm looking for a web UI with forms that I could either populate specific fields and or do API get commands against a VCenter or wherever the server is being built to populate the specific fields. The fields that get populated would be stored as the variables.tf file and when someone hits submit, it would run the actual Terraform command terraform apply to build the server based on the variables. My guess is the terraform binaries would have to live on there so it could run in the background.

It doesn't have to be some super fancy web page, just something that I could potentially make look cool for Director level folks.

Also, I don't want to use TF enterprise, yet. I've looked into a couple of open source projects (atlantis and terrahub) but none seem to be what I'm looking for.

I'm far from a web developer so any help would be awesome.

What do you think would be a modern vision on integration?

What do you think would be a modern vision on integration? I'm noticing more and more a trend to event-driven architectures, with possibly lots of consumers, sometimes with a centralized event bridge or stream.

This does eat away some from the more synchr natured systems, altho I feel they too have their place in the ecosystem.

Would one be preferable over the other with ideas about scaling out, future work and ops? Is a vision, event-driven, unless there is a specific need for sync ? Or the other way around?

And talking about event bridges: Contracts for message structure are now possible not only at the endpoints, but also at the middle layer and I wonder if that is a good thing to do?

I'm pretty interested in you guys' opinion and experience.
