Questions regarding CI/CD and Cloud provider cert

Hey guys,

So I'm studying my Devops path for about 5 month's ...

So I have three questions,

1- I know that the most popular tool right now is Jenkins, however after working with it for a few weeks this tool is a mess.. I think that Azure devops is much more useful and easier, should I make this transition or stick with the most common tool in the industry ?

2- Which certification is it recommended for me to study in order to have a high knowledge in cloud integration, AWS (for example) in regarding to the Dev-ops world? (deploying apps on the cluster, monitoring and etc...)

3- Is it a must to know a programming language? if I know Bash can it be a replacement or I need them both?

​

​

Thanks in advanced to everyone willing to assist!

Which platform would you recommend to deploy a React/Node application?

Hi,

I will soon need to deploy an app with a React front-end and a node/express server connected to Mongo Atlas. I'm a complete noob with deployment (I've just deployed free static sites on Heroku, Netlify and github pages).

My expectations are:

A service simple to use, that don't require maintenance (so no AWS).
A reasonable pricing (of course\^\^). By reasonable I mean 15$/month or so, for both front and back. If the app gains traction, then I'll be happy to invest real money, but for the moment, I don't even know if i'll get 1 customer. So I gotta be careful with the cash.
Continuous deployment from git repo
Ability to connect with Mongo Atlas.
Decent performance (I've heard that Heroku dynos must restart every 24 hours and may be a bit slow to handle the first connection. Since I've got websockets running, I'm a bit afraid of that).
Optionally: ability to deploy a staging environment from a dev branch to check changes before merging into master/prod.

I'd prefer to stick with the same provider for the sake of simplicity, but I'm fine with using two different services if needed.

I've heard about Render, but it seems it doesn't support Mongo Atlas, is this true? There are many solutions out there, and quite frankly, I don't know sh*t about them, nor about deployment.

Which service would you suggest for my usecase? Also, is it compulsory to dockerize my front and back? For the moment, it's just a classic app with a dist/build folder. I need the server to run on node >14 to handle Intl api
(to translate dates). Is a { "engines" : { "node" : ">0.14" } }
in package.json
enough?

Thanks for your feedbacks!

Cli tool or library for obfuscating sensitive data

Hi,

Does anyone knows a library for obfuscating and masking the usernames and password inside of text file content?

Like Gitlab Ci does it, masking all sensitive content

I don’t care about the language in which it is written( hope it is not .net,lol)

Basically, want to use it as a post processing step in one of my own devops tools , which gonna save all the commands from bash history

Update:
Found new tool myself, teller. Need to try it though, they say it can remove sensitive data and manage secrets

DevOps team : how to grow and move forward

Hi All,

We have around 10 DevOps engineers , mostly working on their own projects inside same company, for different clients

Just to simply, 1-2 engineer per a project

Head count growth steadily with like +3-5 engineers a year

There are some overlaps in technologies between projects, but no more than 40%. It is almost impossible to unify them, due to different domains( finance, healthcare, ai and etc)
Project of different duration, scale and complexity

I do work as someone like a ‘team lead’ in our devops chapter, covering some of the onboarding , mentoring and other responsibilities. 80% hands-on , 20% on org things

As we work all on different projects, we have a bit weak cross project/team knowledge sharing and oftenly implement same stuff with different approaches
Ive heard from many of colleagues of same company size ( about 200peolle) about the same things. Mostly all companies under <1k people have it to certain extend. Learning and sharing requires the whole framework and long term investment

It is easier when u work inside same project, then there is a clear benefit and interest in continuous development & sharing

But when you work separately and shared some piece with someone, there is always a drift when project continues to grow and someone has to maintain it

We done some small internal workshops in past, like open ended discussion on technologies and how they are used in projects & potential opportunities
But it is not always clear of which benefits we get out of it and how it helps us. Clear part is that we know what people are working on and bit diverse their typical working routine


Maybe someone was in our situation.
What to do strategically to make whole thing more standard?
Are tips and trick for short and long term success?
How you managed to solve the cross team communication?
Is there anything we can do now to build a good foundation?
Anything that we should look at in first turn?
Does anyone have a success story they can share?

Best Regards,
Vlad

Deployment Config vs Deployment

Hello,

I am new to Openshift, we have tasks of deploying few containerized applications onto the Openshift 4? I like to understand from the experts here, what’s are the differences between the Kubernetes API kind deployment vs Openshift deployment config? Openshift supports both deployment and deployment config? If yes, which is the recommended way of deploying apps?

Thanks for the help

Looking for light weight kubernetes alternative for local development and learning

Hey. I wanted to check out the world of devops so over the past few weeks I've dockerized a simple application and got it running in microk8s with a nodePort for accessing it. I use a dell t30 and prior to using kubernetes I've never pushed this tower to 3% cpu usage, but kubernetes running idle / just my simple hello world image brought the average up to 15% with frequent peaks over 25%, much of that being just a process named kube-apiserver.

I don't use this home server for much but I don't think I want to let kubernetes consume most of it. I'm new to the space so pardon my asking - is there even an alternative for what I'm asking? Or once you enter this space, do all similar technologies turn that host machine into a container manager without much room to do much else besides manage the cluster? I am reading about nomad now as a simple alternative to kubernetes - simple sounds good for my interest in learning, but will I see the same insane overhead / cpu usage?

My needs are very simple, I'm trying to make my website and other small projects easier to manage, upgrade, redeploy, etc and do so in a modern way. Currently my website is a compiled golang binary living in a tmux pane! I'm also of the old mindset that handing my application over to docker and handing that docker image to kubernetes will continually add overhead and performance degredation. I'm willing to try it and see for myself - although I suspect doing all of this on a single local machine will have drawbacks because it's not what the tech is meant for.

So, tldr, are there any container (or non container) managers solving a similar goal but on a smaller scale or at least with a smaller footprint?

Guide on migrating off a self-managed Gitlab instance to gitlab.com

We recently migrated from a self-managed Gitlab instance to gitlab.com. The system administrator of the self-managed Gitlab instance said this would simply entail a git pull && git push and that the migration will be done quickly - depending on your usage of Gitlab, this is either a naïve oversimplification or straight forward dangerous. The truth is more nuanced and entails quite a bit more work. Since the migration took us a couple of full working days and we wrote some reusable checklists and code in the process, we have quickly jotted these down. Maybe somebody else can also make use of it.

Interactive map of Google Cloud Services

Hi guys, I created this interactive map to help get an overview of Google Cloud Platform.

Interactive map of Google Cloud Services

Might come in handy for anyone working towards a certification, or for anyone working with GCP from day to day.

I am now working on a similar map covering Kubernetes, and I was wondering if you had any specific topics that you would like to see covered? 🥳

Transition to DevOps without getting burned

Guys how's it going
As the title says i'm looking to make a transition to DevOps role, but i'm burned out haha

I have a solid background as a Sysadmin using Linux, docker, AWS, bash..and also I have my CCNA
The thing is i'm trying to learn a lot of techs at the same time and it's frying my brain

Last night i've stayed up to 1am (after 9hs of work) with Python/K8s/Ansible/Terraform.. and I got completely ruined.. and got nothing out of it

So i guess my question would be, what to learn next? Python? K8s? More Cloud? Terraform? CI/CD?
Tere are so much things that I honestly don't know where to begin and focus on.

I'm 35 now, and I want to keep learning, but i feel completely stuck.

Thanks!

Web development - Smooth transition or clean cut?

Hi everyone,

I am in a kind of "luxury situation" and would appreciate different opinions on my situation in order to make a sound decision.

I worked as a sneior it project manager at a big e-commerce company and right now I am doing a full-time web developer coding bootcamp, which is ending in around 5 weeks. I am having an offer from my old company to start again as a senior it project manager. My ultimate long-term goal would be to work remotely as ruby/JS backend developer.

Should I take the job and transition slowly (doing code wars and own projects on the side), advancing my skills only in my freetime and search a new job on the side or do a clean cut and search a jr dev. position (probably earning 40% less money for the next years) and having more time to focus on advancing my skills as my day-to-day job?

Thanks for your support girls and guys :)

What and How each stream works?

Can you ELI5 what each service/framework does that's bolded?

For data ingestion, you write and build a piece of code in IDE (Gradle? is used and Artifactory? is one of the confgs setup for Gradle, Metorikku and DTSv3 for a version config), you commit this code to Stash, use Bamboo to do CI/CD, create a keytab, conf.json, and generate dts credential on a terminal, copy this json file to s3 bucket, and finally you trigger on Airflow?

Running Jenkins and Gitea itself as container managed by Kubernetes or locally on a server?

Dear Community,

**Fix assumption:** I have a RHEL 7 or 8 server (physically) to setup some CICD Tools. (I know that there are better operating systems for my use case, at least following opinions in certain blogs.)

**Goal:** Setup an experimental DevOps environment with the goal to gather experience to setup in a distant future a real DevOps environment for a small team. I want to use the following tools:

* Gitea
* Jenkins
* tests, deployments etc. are run in pods using a container service and kubernetes to orchestrate the pods containing the containers

**Question:** There are a lot of guides telling you to run Gitea and Jenkins themself as containerized application inside a kubernetes cluster. I would like to understand why and the pro and cons. So which of them should be run as container inside a pod (Gitea, Jenkins, both?)? Why and why maybe not.

**Thoughts:** The probably major factor to run those applications in pods is that the system becomes more resilient. Disadvantage could be that it is more difficult to deal with persistency and consistency of databases and storage. I also already started a thread towards this topic where I also added as comment to some answers this question: [https://www.reddit.com/r/devops/comments/mw6jp7/setting\_up\_cicd\_git/](https://www.reddit.com/r/devops/comments/mw6jp7/setting_up_cicd_git/)

Carbon cost of infra-as-code

I've been toying with the idea of showing carbon emission estimates as part of the free/open source Infracost CLI tool for Terraform projects.

I've seen estimates mention that data centers consume around 1% of the global electric supply [1\] and this could increase to between 3-13% by 2030 [2\]. The wider ICT ecosystem accounts for 2% of the world's carbon emissions, putting it on par with the entire aviation industry [3\].

It seems like it might be possible to show "carbon costs" for basic compute (ec2), storage (s3) and data transfer but not easy for services that build on top of these raw primitives, e.g. DynamoDB. However, I'm wondering if people would find that helpful, or if it would change anything about "cloud waste"? That waste is estimated to be around $17bn out of the $50bn that was spent on IaaS in 2020 [4\]. The main causes of the waste are idle resources and over-provisioned resources so maybe if devops/SREs/devs have the carbon costs, they can incentivize people to use those resources more efficiently? Anyone seen infra carbon costs in their organization's carbon accounting reports?

NPM+NODEJS

Hello guys, hope all of you are doing well, yesterday my team lead asked me to do a small session about NPM, explain its purpose and how can we use it as a DevOps engineer, knowing that I have a piece of good knowledge in javascript (basic staffs such function, oop, etc) but I have never used npm, so my question is as a DevOps engineer why we need to learn node js & npm, and where we can use them?

Thanks.
