Idea Troubleshooting CLI - What do you think?

I thought of creating an open-source project which includes a Troubleshooting CLI application that supports macOS, Linux, and WSL2 (Linux VM on Windows).

This CLI will assist DevOps engineers to perform an analysis on common issues (challenges), without the hassle of repeating common tasks.

I call it tbs (troubleshooting)

As always, it's easier to explain with an example -

$ tbs --help

Usage:
tbs vendor service-name action [-arg, --argument]

# Example:

$ tbs aws efs mount --id my.efs.id --efs-mount /data --local-mount-path /home/ubuntu/data
[DOCS] https://docs.aws.amazon.com/efs/latest/ug/troubleshooting-efs-mounting.html
[LOGS] Describe EFS
[LOGS] Describe VPC
[LOGS] Check if EFS is available (provisioned)
[LOGS] Check if DNS support is enabled in VPC
[LOGS] Check if EFS is reachable from local machine - ping
[LOGS] Check if EFS DNS can be resolved from local machine
[LOGS] Attempt to mount EFS on local machine
[RSLT] DNS support needs to be enabled in the VPC - my-vpc-id

What do you think? Is this something that you'll use? I'd love to hear your opinion

If you don’t use a secret management tool, you’re doing it wrong

I worked with Hashicorp Vault for few weeks, and I find it very useful. I wrote an opinionated blog post about it. If you consider using Vault, check it out.

How do you organise your repos for your different environments, platform and the applications that run on it?

I’ve recently joined a company that
has done this by horizontal slices - there’s a repo for cloud accounts for all teams, a repo for all the kubernetes clusters that run in each account, a repo for all the applications, etc. This is causing some friction as there’s multiple touch points for solving a problem like “can I have some infrastructure to run my code?”

A related but separate problem is that much of the code in these repos is created by copy-pasting from similar directories. There’s a lot of drift.

Other places I’ve worked have had varying other, usually slightly more granular, occasionally more monorepo style approaches.

How do you do it? What do you like and dislike about the approach you’re using?

Automated Fuzzing, yay or nay?

A quick google showed those:

​

* American Fuzzy LOP
* Radamsa
* Honggfuzz
* Libfuzzer
* OSS-Fuzz

Blog Tracing System as an Application Operations Log

Hello everyone,

I wanted to share with you one particularly valuable use-case I found while using our tracing system. Basically, we were annoyed with existing solutions and the need to share our data with different SaaS vendors. We built our own system and made it open-source. Since then I used it on a bunch of personal and professional projects.

In my blog post I describe this use-case. Basically, it serves as a log of operations your system does.

It saved me a couple of hours (well, I got paid for them) when a customer claimed that their valuable data was deleted due to a system bug (we couldn't do soft delete there due to privacy and legal reasons). We were able to confirm seeing the exact request the customer sent that it was indeed a user input error rather than a bug. I had to restore it from a snapshot of course but they had to pay for a special support case since it wasn't our fault.

Transitioning to Senior DevOps Engineer

So been in IT (started in ops) for 8 years now. Started DevOps 2 years ago (cloud architect prior) but now my manager is pushing for me to take a Senior role. Basically doing the same job I’m doing now, just with the recognition.

I’ve been getting bombarded by recruiters lately and have been entertaining 2 opportunities. Very nice pay bump. I would be going straight into a Senior DevOps role with a team that’s been together for a while. Question is, should I stick with my current company and get leadership experience there or take the jump? I do learn fast and love a challenge.

Any recommendations or similar experience in these situations would be much appreciated.

Advice/Opinions Wanted Artifact Registry options in 2021

Hey!

Hope y'all are doing well.

I'm looking for peoples advice, opinions, experiences or anecdotes on how they do artifact registries. I work in a company running Sonatype Nexus. It's deployed on top of Openshift Container platform (4.5) which runs in AWS. It runs in a pod with persistent storage in a shared cluster running a flat pod network (every pod can see this registry). It would be a big deal if it were to break. A majority of the jenkins jobs depend on this: all builds, deployments, promotions etc.

It could fail for many reasons: if the pod goes down, runs out of storage or inodes, the cluster gets upgraded, an AZ fails, the node the pod runs on gets restarted (and many more) then the house is on fire. Personally I like the idea of not having to manage any of that. I used to work with artifactory online, which was a dream.

We use Nexus for:

hosting helm, node and maven artifacts
hosting docker images
as a proxy to external registries like [https://registry.npmjs.org](https://registry.npmjs.org)

Keen for opinions on:

SaaS vs self deployed
HA setups
If anyone's using Openshift 4: How do you do registries?

Thanks!

Help with a student project

Hi , so i'm currently a cloud network engineering student.

for a graded assignement my professor proposed this project to work on this semester : "network configuration of microservices with docker".

Now this doesn't seem like a project i want to spend the next 4 months working on . So , i would like to improve it a bit so it's more challenging and worth spending that much time on . I can't ask my professor for a new project but i can ask for small changes .

any ideas on improving it?

PS: i'm mostly interested in cloud engineering. I've worked on previous cloud network and devOps projects.

thanks!

Finding your way into chaos engineering

Hey everyone,

We recently spoke with Ana Margarita Medina from Gremlin to hear about her unique path into this field. Ana is a bada** that has been bucking the system since she was a kid. From no ivy league to college dropout to Silicon Valley, Ana has always been the underdog. She battled through discrimination, burnout, and still came out on the other side in a better position than before.

We hope her story may serve as inspiration for someone looking for the resilience they need to push through the hard times and create the life they want, in the field they want. (Mods can delete if this isn't applicable but we thought it could help someone out there that is looking to find their way!)

All devops I met are against using Microsoft products (Windows, .NET Core, C#, etc). I am curious if the devops here in reddit are also against Microsoft software products and what is your rationale?

I only met a couple of devops in my career and they are all against Microsoft (Windows, .NET Core - cross platform, C#, etc) and will always prefer non-Microsoft solutions . I am curious if that is the same with the devops here in reddit and what is your rationale?

Creating Kubernetes Resources via UI and creating testing/staging environments

I'm currently planing a devops project for university and I would really appreciate any tips and recommendations.

Our Institut is involved in a system/application where you can model an architecture, meaning you can create components and interfaces that resemble Microservices and their connections between each other.

For my project, there are basically two goals/features:

1. Make it possible to create a the Kubernetes Resources (pods and services) for the created architecture modelled with the given system. The system lacks input for values that are needed for the Kubernetes Resources, such as Docker Images and Ports, so I would need the create inputs for these values.

2. Once we have created the Kubernetes cluster, we want to be able to create different testing/staging environemnts

Here are my initials ideas on how I would implement this:

1. Feature: For each component we have, we create some input fields where we can fill in information needed to create the kubernetes pods/services, such as docker images and ports. Then we create the kubernetes resources with this information via the kubernetes API.

Here is my first question: Do I really have to create these UIs from scratch, that basically just serve as slightly simplified yaml file substitution or are there any ready made solutions to this?

2. Feature: To create testing environments, I just create a namespace, for example `beta` and then take the already created kubernetes resources for the component, allow changing the values for example use an updated docker image and just apply these resources in the new namespace.

Is there anything wrong with creating testing environments by creating new namespaces. Are there better solutions to this? I heard about Terraform, which apparently can automate creating staging environment, could this be useful for my project?

How would you implement these ideas? Any recommendation and related works are appreciated!

Why is the AWS DevOPS Pro Cert so valued?

The only real DevOPS service that it tests in the exam which is used in lot of places is Cloudformation. Apart from that I don't see a single other service in the cert that is relevant to DevOPS in real world. I have worked in many organisations (both big and small, all in DevOPS role) and these are the services I have always used.

\-Terraform

\-Ansible

\-Docker

\-Kubernetes

\-Prometheus

\-Python Scripting

\-CloudFormation

\-Jenkins

So as you can see, apart from CloudFormation none of the services tested in the DevOPS pro exam relates to real life tools used by devOPS engineers everyday. If I was a recruiter, I would personally hire someone who knows the tools mentioned above rather than who have a AWS DevOPS pro cert.

Is a DevOps culture possible if 'You build it, you run it' is not an option?

Hey there. It am working for a company right now that is trying to adopt DevOps and agile methods to fix the issues we have from doing waterfall software development in the past. We are somewhere in the middle, probably like a lot of other companies aswell.

A question just arose in my mind which is "Is a DevOps culture possible if 'You build it, you run it' is not an option?". We are developing software that gets distributed to our customers then and they manage and run it e.g. in their data center. We only help e.g. during first installation or update. Therefore I guess our development teams are just not able "to run" what they "built". As we have quite some customers that run our software in an air-gapped environment there will also never be the case that all systems will be "run" by us. Additionally our teams are not big enough to "run" all the software installations of our customers. Its a bit similar as if you would expect Microsoft itself to "run" all the installations of Microsoft Office on each home PC around the world. However, I guess Microsoft is getting with Office 365 in a position to actually run what they build ;). As said for us, that is not an option.

With all this, can we even enable a proper DevOps culture? From my understanding getting Ops very close to Dev is a key element, thus the name "DevOps" ;). But this does not look doable for me right now.

Git Repo(s) Structure

We're just starting down the IaC path. We're looking to use GitHub for our repo(s). And that just adds more questions.

Anyone have any advice on structuring an IaC repository? Multiple repos? One big repo? Are there any best practices or examples? I'm fairly new to git but if we put it all in one big repo, our team will need to pull down the full repo locally, right?

I'm hoping to see some examples to better understand how we could/should set up our repo structure. Anyone have pointers?

What type of things should I ask/learn from my colleagues

I got my first cloud SRE/DevOps job 2 weeks ago at a medium-size company. I am a university graduate who went to 4 month coding boot camp for software development which is how I got this job and I am 23.

My colleagues are a lot older, one has 20 years of experience prior as a developer and others have a similar amount of experience in IT from different backgrounds such as my boss who works on cloud security.

I am wondering what are the best things I should learn and ask from them to become a good engineer as currently, 90% of my time is training on A cloud guru.

I am training and will work with the following stack; AWS solutons architect, REHL 7 , Jenkins, Boto3 and Python, Ansible, Terraform, Bash scripting, Splunk, Datadog.
