Traditional on premises to Cloud

I’m a network engineer would love to more about devops. I don’t see any use to go above VM’s for small org like us. But want to learn so we may find a way thats useful for us and also reduce the cost in the long run. Where would small orgs can use devops? How containers came into play? Is there a good book that gives us the idea of moving to cloud and from on premises and from VM’s to containers? Where the regular IT is going in terms of research? If we don’t have a app on our own and uses only third party apps? Any useful going this devops route?

Are there any reputable degree programs out there that specifically focus on DevOps?

The main thing holding me back from getting a degree is I don't want to be learning outdated or irrelevant concepts that I'll never end up using again. I know of WGU's Cloud Computing program so if anyone has some opinions on it feel free to speak up, or if there are any good alternatives out there from other reputable colleges would be great to know.

What can I do if a company warned me about copyright infringement on a dictionary?

I developed a dictionary, a simple collection of words which I scrapped from several dictionaries and removed all the visual garbage and advertisements, as a lover of linguistics I am. Now the legal department of one of those dictionaries sent me a legal warning to shutdown the site.

I am totally lost, thus I pose the following questions for which I am grateful that someone could help

Can they shutdown my website? The TLD is .pt and the server is in Germany
If I move the server to Russia, for example, with a TLD .org, will it help?

Thanks a lot

Thoughts on internal developer platforms?

I wanted to ask regarding thoughts about introducing internal developer platforms.

The goal of DevOps at the end of the day is to not be a bottle neck and to create pace. The way you create pace is by automating everything so that developers can move at their own pace.

Wouldn't introducing IDPs be a good way to do this?

In an ideal world, DevOps engineers can template out infrastructure modules for common use cases (think containers, static sites, etc.) Developers then can just deploy the needed infrastructure that will setup and run their applications without needing to be exposed to all the intricacies of infrastructure. If this is true, wouldn't IDPs be the best abstraction layer for developers so that they're not forced to be come infrastructure experts?

Has anyone here implemented / built out an IDP for your company? If so, how successful has it been?

Can single Loki instance works with multiple projects?

I am wondering whenever I can run Loki instance for all my projects and correctly authorize them with something like access token, or I will have to create as many Loki instances as many projects I have (which does not make sense for Grafana single DataSource).

C is missing from the majority of CI/CD implementation

The vast majority of CI/CD implementations that I saw, especially among enterprise companies, are completely missing the point of merging to the mainline frequently (e.g., at least once a day). Yet, everyone claims to be doing at least CI, if not CD. Why is that?

Pay cut for better experience

Hi everyone,

This is a follow-up to a previous post I made a few months ago re: my transition to DevOps two years ago. In short, I was promoted internally to a DevOps role but haven't gained the experience I expected (https://redd.it/m0tg7y).

At the recommendation of some who were nice enough to provide feedback, I've been applying and expect to get an offer from a company to join their software engineering team as a Devops Engineer. The key differences between this new opportunity and ym current role are, I will be supporting a production software product (not internal IT), will be embedded with software engineers, and I will be focused on build/test/deploy versus simply automating cloud infrastructure.

The only drawback is there would be a significant pay decrease (~30/40%)- mostly due to accumulated RSU value over the last four years at my current company. The wage would still be very livable and comfortable.

My gut tells me to take the hit as the experience will get me closer to where I'd like to be in the long run. Is this a good idea? Tell my why/why not.

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

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.
