Is an easy interview a red flag?

Just got made an offer for a role. It was a two stage interview with no tech test. First stage was just general devops questions, second stage was scenario based questions. Honestly I feel I'm too junior for this role and I'm quite nervous to take it. Is an easy interview a red flag?

Edit: there's a lot on the job spec that I don't know, such as K8's, Selenium.

KubeCon Europe Drama!

Apparantly the CNCF removed the mask mandate for KubeCon Valencia because Spain (the host country) also removed the requirement across the country.

Queue some backlash from the Twitter community, specifically Kat Cosgrove (https://twitter.com/Dixie3Flatline/status/1517485638462803969?t=h1ZcWoDjWnMzHw2nXzldgg&s=19) and the CNCF basically tried to cite her and said her conduct was not appropriate.

TechTwitter blew up at the CNCF, and then the CNCF shortly reversed the decision.

Jenkins MultiBranch Pipeline

Published my 7th video in the series "Jenkins Tutorials for beginners" and this time it is for

"Jenkins MultiBranch Pipeline" 🔥🔥🔥

​

If you are a beginner at Jenkins/DevOps, I'd suggest you check out the previous videos in this playlist as well to get started with Jenkins and understand the concept of CI/CD.

In this video, we will be looking into Jenkins multibranch pipeline. Video #6( Jenkins CI CD Pipeline Tutorial) is the pre-requisite for this video so, make sure you watch that before this one.

When we are working in an enterprise-level organization or a company that utilizes git-based SCM to its full capabilities including pull requests, git-flow, git branching, etc. then it is really hard to maintain multiple Jenkinsfile for one repository and to create a separate Jenkins pipeline for each of the branch is a hassle, and could introduce a lot of technical debts that is when Jenkins multibranch pipeline comes to the rescue. It scans the complete repository and finds out all the Jenkinsfile(s) in multiple branches and creates separate Jenkins pipelines for all the branches with the Multibranch pipeline as the master job.

Golang for devops

Hello everyone

I have been writing for some time on how to use Go for Devops. Instead of publishing a list of separate articles and tutorials, I have decided to put everything together in a coherent form as a book.

I was wondering if there are any topics that you would really like to see included in book about using Go for Devops?

Currently, my draft version has the following sections / chapters (draft titles, but they relay the contents):

Introduction to Go
Building apps and scripts
Script scaffolding
Command line tools using go
Talking to clouds
Working with databases
Working with API's
Common recipes

Good resources for ansible & terraform CI/CD

Hey everyone, I am looking for some resources to help brush up on how to integrate terraform and ansible in CI/CD. I would also love to hear how your companies automate deploying IaC.

Thanks!

Work Item Scopes

This is a rookie question, but just wondering how do you keep your work items only with the scope of the project. Its getting confusing how I can see work items from other projects.

New to dev ops and want to know how to set this up.

DNSControl - the most underrated DNS tool

dnscontrol is probably one of the least talked about DNS tools that is amazing to use.

Maybe my beard isn't gray enough (and everyone is talking about it/already knows), but if you have never heard of it until today, you're welcome.

Looking to get into DevOps down the road.

Hi everyone. I’m sure this gets asked all the time so if there is something obvious that I missed, please let me know.

I am on a path to end up in DevOps a few years from now. Working my way up through a Systems Engineer path.

In your experience, what are the best things I can do now to best prepare myself for being a good DevOps Engineer?

Also, it seems that DevOps is a pretty broad category. What is DevOps to you in your specific role?

I have started learning Python and getting familiar with the idea of Docker. I run Linux as my daily driver so I am fairly familiar with that environment but still have a lot to learn. Any advice is appreciated. Thanks!

Links for resources like Udemy is greatly appreciated.


Thanks a lot

Linux repository manager for binary packages

Hi y'all!

I'm looking for a solution to host and manage artifacts that are actually Linux *ipk (just like deb) files for a custom solution. Right now we have a jenkins building some packages and we'll start to have plenty more soon.

So we need get something working to handle all the generated files, ideally indexing them (we have to use opkg for that), but to handle the versioning and storing.

For the time being we are looking into Apache Archive for it, but if any other FOSS and selfhosted solution is better I'm willing to do the switch!

Thanks!

Money to work ratio

I’ve been working in devops for 3 years, I’ve only worked for a single company my entire career. I love my company and the people/culture, but the pay is less than what a lot of other tech companies offer. I started at 85k with a 10% yearly bonus reliant on company performance. I’m currently at 105k with the same yearly bonus. The work is interesting, but not extremely difficult and is fully remote. So I can work somedays 2-3 hours and that’s it. What’s everyone else’s experience? I’m trying to determine if this is a unique experience and I’m living my best life, or if this is a general experience. I’m based in Boston as an fyi for COL.

Circleci Can we use multiple workflows for multiple type?

I’m new in circleci. I want to install my infrastructure via terraform after that I also want to trigger my build, deploy and push command for aws side. But workflow does not allow me to use plan_approve_apply and build-and-deploy together in understand one workflow. I also try to create multiple workflows (like below example) for each one but also it didn’t work. How can I call both in single circli config file

IAM vs Authentication lib - what's the use case for each one of them, and why?

Is there any case it's preferred to use an authentication library like Authlib (python) or Passpost.js (node.js) instead of an IAM such as keycloak?

What are the advantages of one compared to the other?

Call another Jenkins job multiple times

I have a freestyle Jenkins job that has a parameter called branch, which is taken from a file.

Currently, in the file, it's defined to be equal to master:

branch=master

Then, as part of the build, it calls another Jenkins job with the branch variable.


 

Now, QA wants to have the branch variable have multiple values (for example branch=master,branch1).

Thing is, now I would have to call the other Jenkins job multiple times.

In Jenkins (preferably freestyle), is it possible to call another job multiple times in a loop with different values every time?

Thanks ahead!

vkv: recursively list key-values entries from Vaults KV2 engine in various formats

Hi I wrote this small utility in order to view large and nested entries in Vaults KVv2 Engine. Maybe it is interesting for you guys. I plan to add more formats, for instance displaying the current used token capabilities on each path and entry:

There is no such thing as too much logging - or is there?

What’s a modern day best practice around logging? How do you approach this? I myself like to log as much as possible, my boss swears there should only be debug and error logs.
