How did you become a decent developer?

I need your help, so basically I started working as a devops Consultant, one year and a half ago. But I am a bad developer, also I was lazy I did not put much effort into what I was doing but I am working on changing that. So basically, I was a brilliant student, I could get good grades with a decent effort, but I am not really a good developer (it hearts me to say that but it is the case). Compared with my ex-student friends, most of them succeeded in work but not me. I also think one of the causes, is that during the university, I was more focused on my studies, so I was only studying theoretical courses. I have never developed something important, so when I started working, I can say I started from 0.

​

I am really motivated to change that, and my goal is to be able to reach seniority, I know it will take years, I am not delusional, but I want to ask you what is the best approach that made you a capable engineer, I need to hear your stories and what are the important aspects that an engineer must have to become a great engineer, that may help me to enable me as a DevOps.

​

Thanks

Nigerian report needs better internet

I hired a recently graduated front end developer from Nigeria and she’s fantastic. I’d say she’s my best and most reliable report with the exception of her internet connection reliability. She often can’t participate in standup because our video calling suite is pretty heavy for her connection. We also have grown frustrated with the fact that she can’t screenshare on calls for the same reason.

I’m trying to purchase this for her but my company card keeps declining. I tried my personal cc; same issue. Then I tried another link from a Nigeria vendor (Jumia) and same issue.

Any recommendations?

Deploying a monolith in 2023

Hi all.

Context:

I'm a BE and FE software developer and have some (basic imo) knowledge on deployment and observability.

I have a business idea, I'd like to try building (only me for now, but another person might join later). In order to prove that the idea is worth investing more time and effort, I'll start with it's most basic version, which is essentially a CRUD web service and a web UI with some extra stuff on top. My plan is for more complex features to be implemented after initial release.

In all the companies I've been working on, we've either started projects in k8s or migrating a monolith to microservices in k8s, or (around 7-8 years ago) working on a monolith deployed to a fleet of VMs.

I consider microservices an overkill for what I'm trying to build. They add many logical complications like handling distributed DB transactions for example, but they're pretty much all I know how to deploy and monitor.

Questions:

Is there a "proper" way of deploying a monolith in the current k8s-and-microservices-oriented world?Can you give me some advice or point me to an article I can read, or a set of tools I can try?

How zero trust DevOps eliminates risk of unsanctioned cloud access

So I just read an interesting article on zero trust DevOps and its impact on addressing unsanctioned cloud access risks. One key point that made me think was the concept of Just in Time security, which grants access to resources only when needed and for the exact duration required, thus embodying the zero trust principles.

Here's the article link: https://www.securitymagazine.com/articles/98663-how-zero-trust-devops-eliminates-risk-of-unsanctioned-cloud-access

Are ya'll familiar with this practice or other practices that help to improve security? I'm fairly new to the industry and would appreciate pointers.

DevOps Checklists - the grownup and gone to university of the roadmap.

Yep cheezy get your attention headline.

So I've just come across The Checklist Manifesto (thanks to Daves garage on YouTube)

What would be your checklists for your devoos work?

My current one is...

Take user story - check
Read the requirements - check
Git pull - check
Git branch - check
Write unit test - check (ish)
Git commit - check
Write Lambda - check
Gut commit - check
Red green refactoring Lambda with unit test check.
Git PR - check
Git merge - check
Dev build done - check
Write integration test - TBD
...
Deploy to prod - TBD
Review monitoring & logs - TDB
Have a cuppa (wait for complaints) - check


So on and so forth,

Thinking about it I could probably group them into sets of checklists with each checklust having a dependency on the previous ones being completed. Plus there are others for other types of DevOps work.

What checklists would you find useful?

NoOps subreddit

Hey all,

I work for a cybersecurity company and I’m writing a blog post about DevOps and NoOps from the security point of view.

I’m fairly interested in the NoOps concept as it’s new to me so I checked if there is a subreddit dedicated to the subject but the ones I found are private.

Do you know if such a subreddit exists and if I can subscribe ?

Thx guys,
Cheers

Cloud Companion is now open-source!

I'm so excited to announce that I'm open-sourcing my cloud-management tool! I think that it is now in a good shape to be built easily and adapt to new features. Feel free to download the source-code and report any bugs or feature requests to https://github.com/ahmedyarub/cloud\_companion\_public/

All the feature requests would be scheduled and released as soon as possible.

Dynatrace end-to-end map flow

I'm trying to set up some sort of a dashboard in Dynatrace that would help teams identify where the major incident is happening. The team would like to see the smartscape topology view, but the system is so compex with many thousands of services and many more thousands of processes that at certain places the map is just solid gray from the amount of arrows.

The thing is that we need to educate people how to use this tool to help them in major incidents and at the moment we don't have a great way of displaying the end to end stack.

Has anyone came across a good way to do something like that in a big company?

Thanks in advance!

Overwhelmed


I am going through the process of attempting to get into a free tech program. We were told during the information session that no tech experience was required. It was a lie. The application took me about 1.5 weeks to complete as I reworked my answers constantly and did extensive research. Yesterday they sent me the materials for the interview I have this upcoming week. They want a presentation with diagrams on a specific topic and I am overwhelmed due to my lack of experience. I have taken a Intro to DevOps course on Coursera and some Scrum related courses on Skillsoft. I have been looking at YT videos and reading articles on varying types of Architecture as well. I am overwhelmed. If I got through this interview there would be one last presentation to do but I would have a month to prepare which I could handle and have completed by or before the due date. The class would start this summer and go till the late fall. I am not sure whether I should give up. I am terrified that I won't be prepared😞.

Choose hosting provider and possible CI/CD flow

Hello everyone,

I am currently building spring boot web app backend. I was thinking about possible hosting for it. If my app eventually receives a lot of traffic, it should receive around 25000 requests per day, about 1000 per hour.

My question is: what hosting service should I use in order not to have over-priced/over-complicated architecture? Of course I should keep in mind that there might be more requests if app grows. Currently my choosen stack is AWS Lambda. And for CI/CD I choose Github actions and Jenkins.

Thank you for the answers.

Career Opportunities Out of College

Hi! I’m currently a junior at a university and happened to land a DevOps internship for this summer. I originally looked at SWE and DE internships but with no luck. However, since I have a decent AWS knowledge, I got lucky with this DevOps opportunity. I don’t know if I will like it or not, but if I do and I end up going in the field, I’m curious about career prospects in this field. How’s the knowledge curve for junior roles? What’s TC like? Is on-call an often occurrence? How’s WLB compared to SWE? I would appreciate if any industry workers on this sub answered these questions. Thanks!

GitLab pipeline for a Java application that uses PostgreSQL and is compiled with Maven

I am kind of a newbie at making GitLab pipelines for [this](https://github.com/callicoder/spring-boot-postgresql-jpa-hibernate-rest-api-demo.git) Java application with a PostgreSQL database.

The application needs a PostgreSQL database named `postgres_demo`. I have successfully compiled the application (`mvn compile`), run tests (`mvn test)`, and built the package (`mvn package`) in my droplet via SSH with a postgresql docker container that I have run like that:
`docker run --name my-spring -e POSTGRES_PASSWORD=mypass -d -p 5432:5432 postgres`

Then via DBeaver I have created required database `postgres_demo` inside that container.

But when I try to use the latest Maven Docker container inside the pipeline, it can't connect to the database. Can you please provide an example of a pipeline that runs tests inside a Maven container with a PostgreSQL database?

So far I have this one:

variables:
MAVEN_OPTS: -Dmaven.repo.local=.m2/repository

image: maven:latest

stages:
- build
- test
- package
- deploy


cache:
paths:
- .m2/repository
- target

build_job:
stage: build
tags:
- docker

script:
- echo "Maven compile started"
- "mvn compile"


test_job:
stage: test
tags:
- docker

script:
- echo "Maven test started"
- "mvn test"

package_job:
stage: package
tags:
- docker

script:
- echo "Maven packaging started"
- "mvn package"


Deploy_job:
stage: deploy

script:
- echo "Maven deploy started"

Instant public URLs for debugging

I always found it difficult to expose a service running on a server by allowing some ports then remembering to turn them off after the job. It is also irritating to download some binary and then execute it and sign up for some service.

With a single command a public URL can be obtained to a localhost port now with https://pinggy.io :

ssh -p 443 -R0:localhost:8000 a.pinggy.io

Just replace 8000 with your port. This will give you an http / https link. It also has a nice terminal interface and a web ui to debug. Makes my life easier.

Screenshot:

https://imgur.com/a/VahFCza


FAQ: Doesn't it open up my system to the internet inviting attacks?
\-> No it just gives access to the port 8000 (or whatever you set) for HTTP requests only. No less secure than configuring your firewall to make port 8000 available to the internet.

Senior with 3YOE - Roast My Resumee

resumee link

I have 3 YOE, my last company gave me the official "senior" title for selling me as a consultant.I still feel like I am a junior. Do you think it's counterproductive? In case should I remove it?

Recently got the AWS Solutions Architect SA-C003.I am not in the USA and I left the previous job for a DevOps internship in a top tier company US remotely, recently started. 3 months duration.

I really hope to continue to work for them, I'm working with AWS and I am afraid if they don't confirm me I have to find other jobs, is the resumee good enough?

Is 2 pages too long? Maybe I used the wrong template?

And if you notice the overlapping times, I am also studying in the meantime.
I don't feel ready for a senior role of course I will look for mid/junior role always in DevOps
