Oh the interview and the rambling thoughts regarding my life choices in Tech in the moment

Though gainfully employed, for certain masochistic reasons that I can't fully account for, I will take 1-2 interviews every year or so. I set expectations that I'm happy where I am at and that I will go through the process and see if we end up on the same page. I do this to empathize with the people that I interview, to see if I need to update my processes, and I keep an open mind that maybe someone has a unicorn role that will make me happy without taking too massive of a pay cut.

Maybe I'm just utterly apathetic at this point or something else is in the mix, but I felt nothing short of contempt the entire time during my interview yesterday. For the first time ever I thought, maybe I'm in the wrong profession. Not only did i find myself not liking the folks that I would be working with but also questioning what the fuck I've done with my life for the last 10 years.

This shop was a little ass backwards in terms of doing a sys-design first and then the coding challenge and then the behavioral. Mid coding interview I said, I think I'm good, I don't really want to do this anymore, said bye and called it a day.

​

I'm at a MAANG company. Pay is great, benefits are great, but I'm starting to realize that this life is not making me happy. I left Dev because I thought I would find more work/life balance and I'm as miserable or more than every.

How do you manage your SSH keys?

I’ve heard different schools of thoughts. On one side, you can generate a new SSH key on each computer and copy to your servers with ssh-copy-id

The benefit I’m told is that if a key gets compromised just revoke that key everywhere and you’re good. That’s great but if you work from a dozen computers and servers, knowing which key to delete could be a challenge

On the other hand, I could generate a single key pair is sneaker net (or scp it) it to each computer I work from. Then, if your key is compromised, you deleye that, generate a new key pair and keep going.

I’m not so much in Devops but I am an enthusiast, so I’d love to hear what everyone else does.

How do you deal with bad commits on live production environment?

Most of the pipelines are in place, but the issue is with the general infrastructure of the project. What I'm talking about is our main "product" - An application built out of 5 ECS clusters. We have 3 stages before prod, but we had an instance where prod failed due to an AWS account specific issue we oversaw, leading to some downtime on our most important, and only customer facing environment (Terraform did half a deployment due to a missing secret, which meant I had to quickly add it and run the pipeline again). I'm just wondering, how would you approach this issue? I understand the concept of blue/green deployments, I'm just trying to figure out the best way to apply it here. Add another (test) domain on prod and have it deploy there first, before reaching actual customers? Or have terraform/pipeline instantly revert to last commit if any issues are found?

Multi Organisation Architecture.



Can someone help me find some resource, I have no idea what its called but the concept goes as follow

So, I want to build something where if an organization registers on my site they will get their own domain. Let's say for org ABC it will be abc.myapp.com similar to how JIRA does it.

Now I am not sure if they create a dedicated database for each organization or use the same database and have some kind of relation. Is it possible to spin up a new database for the said organization? If yes, can anyone provide me the resource or terminology of what it's called?

Let's say I write API to handle all the necessary things for a single org. Is it possible to create a whole server using my code for each organization? taking the above example create-task for ABC organization will route to the server of abc.myapp.com/api/create-task. So every organization gets its own server and dedicated database with all the respective databases.

Also If I update a feature or change the UI then all organizations should receive the new updates on successful deployment.

Can someone please help me find out the DevOps tools require to do such automation?

Thanks, any help would be appreciated.

How to enable network policy in running AKS cluster?

I want to implement network policies in my AKS cluster, but the cluster was deployed without network policy before my time.

I can see network policy as ‘None’ in the cluster network config page on Azure.

Is there any other way to enable it without recreating the cluster?

Should I make my resume simple or more detailed with only 1 year of experience?

Here are some contexts, I'll make it as short as possible. So I will list some overviews of what I've done so far by quarter.
I was a self-taught engineer(Spanish Undergrad), so at first, I was hired as "assistant engineer" and only one of backend developer partially handles deployments , before this job I had "no experience in any of the tools or knowledge but only Javascript", our "dev" environment consists of services and databases running on bare-metal machines using docker-compose and few of them on local Kubernetes cluster, the deployment pipeline was done by triggering Jenkins slave running bash scripts on target machines.

Once service is tested by project managers, it is then shipped to UAT on GKE, as DevOps team will handle the rest.

Q1:

1. Take over full responsibility of managing existed deployment pipeline with optimization and centralized configs over different environments
2. Fully responsible for "local development infrastructures" including handling system or service failures, debug along with the dev when something unusual happens from the log
3. Test, research infrastructure solutions and configurations like database failover, or monitoring systems
4. Handling creation of Dockerfile based on various request

Q2:

at Q2 because I've basically handled tasks that the team leader expected and during this phase our team was super ahead of the schedule, so he didn't assign new tasks to me, with this much free time, most of the things I did in the office were fairly irrelevant to my job like playing around Neovim or just straight up studying documentations

1. Created a four-stage integration testing pipeline along with Slack alerts
2. Write tests for two of the services using Javascript and created a small library for future test in these two.
3. Spent almost 3 weeks to figure out how to apply progress bar to the test, only to find out it couldn't be displayed because the test log is displayed on Jenkins console output. (but hey I know ANSI Escape now)

Q3:

1. Take over responsibility of " frontend team's deployment pipeline" and optimize them with Jenkins pipeline using groovy script to build parallelly and save more than 50% of the time
2. Created a Gitlab CI pipeline and runner for linting existed Golang code base and also linted two of the service with golangci configuration along with teaching some of the devs how to set up linter in IDEs.
3. Fully handle all the infrastructure and services for "Dev" environment meaning if devs found their build failed or want to add new services/requests, I would handle that.

At this point as I found myself doing "less assistant job", I transferred to DevOps team since they were recruiting at the moment, as I found great interest in Kubernetes, networks and Linux systems.

UAT and Prod environment uses totally different flow, with GKE along with GitOps tools, again, I had no prior knowledge of these things before except for Kubernetes because I tried set up local ones with kubeadm but still at a very entry level lol, and since DevOps team has only 3 people including me atm, they handle every product in the company, I had to learn lots of things quickly and be able to pick up some of the tasks.

So, I studied and worked my ass off to a level where I can at least identify the problem and tweak things comfortably while understanding what I'm doing.

Q4: (current time)

1. Maintaining existed production and UAT GKE cluster and deployment, upgrade some of the infrastructures and migrates GitOps tool
2. Migrating one of the main products from VM to GKE(also UAT and prod), set up infrastructures like nginx-ingress or prometheus and services using ArgoCD and helm charts, also handles deployment pipeline and network policies like gRPC load balancing
3. Set up blackbox exporter inside GKE and wrote a small in-cluster operator with Golang that syncs service-monitors according to the data from google sheets (with client-go)
4. Test and research some stuff like SSO solution with Okta or

SAML2, or streaming logs from CloudRun to Elasticsearch via logstash etc.
5. Fixed many bugs for a tool written in Golang

As now I'm heading to Q5, and I'm planning to reach out to new junior DevOps opportunities since it looks like there's not much space to negotiate salary with my company as they're still providing me assistant level salary.

After listing things I did, I feel like I've done many things that can potentially be on my resume, as I've seen many people recommending resume should be as simple as possible, I'm quite worried if I put an overview on my resume, it would seem like I'm bluffing on my resume based on my experience and background, though in reality I spend a lot of my free time studying, and if I put too much information, they won't be interested at all.

thanks for making this far, what do you guys suggest?

Help me understand real use cases of k8s, I can’t wrap my head around it

So from what I’ve read k8s is for mission critical dockers you want to provide high availability for or scale up. Correct me if I’m wrong!

After running dockers 24/7 for years I’ve never had a container randomly fail or been overcome with too many connections to the point where I’m thinking “if I had more this would have solved the problem “. So in terms of high availability I don’t get it. From what I understand k8s does not even sync data between nodes since they’re all using the same volume mount which to me, is the complete opposite of high availability. To me intuitively, k8s should be something that literally syncs multiple containers all with their own individual volume mounts across multiple remote locations.

In terms of scaling, at what point is a load balancer just not cutting it for you anymore? Such that adding more nodes is the solution.

Who actually benefits from k8s? I see too many examples of enthusiasts deploying at home because they can instead of actually needing it, and when I ask for production examples the only thing i hear are examples of Google, the biggest tech company on earth.

I really am not trying to attack k8s and would love to deploy it myself if I see a real benefit from it.

Should I use Capacity Rebalance on spot instances?

Currently, our spot instances are querying an API to test if the spot instance is about to go down. If it sees that the spot instance is about to go down, it immediately sets the instance into DRAINING mode.

Thing is, it's not enough time for the instance to drain itself before it's being taken away by AWS.

After some research, I saw that there's a Capacity Rebalance feature that notifies when the instance is at a higher risk of going down thus possibly giving more time for the tasks inside them to finish.

My only concern with this is that would alert too often and cause most instances to set themselves as draining.

This would be a bit hard to simulate as traffic comes from production mostly. Does anyone have experience with this? Once it notifies, how likely is the instance to really go down? Is there something else I should do?

Thanks ahead!

How to switch to a DevOps based role from a Sysadmin role?

I have almost over 3 years of experience as a Sysadmin working mainly on VMware and HCI based On Premise Infrastructure. I'm looking for any suggestions to get started with DevOps which would help me to land a DevOps based role. I have experience working with Terraform (limited to vSphere provider) and PowerShell Scripts to automate regular tasks at my current role.


I have been applying to multiple job postings available on LinkedIn and even the junior DevOps Engineer role asks for atleast 2+ years of Experience in DevOps related tools.


Any books/playlists which can help me to get into DevOps?

Advice to approach totally weird situation at new job.

I got hired as full stack engineer just recently. Iv started my onboarding procedure. To make this long story short one. Following the basic setup documentation , i discovered that i will have to deploy my app on my own personal aws account that includes using my own CC.

I literally felt anxiety flowing trough my whole body and iv spent whole weekend trying to figure out what should i do. I dont have any AWS experience , i would start slowly working on back-end /front end jut regular coding things and try to learn as much as i can about AWS.

I have raised my concern to my "mentor" he considered it as a joke , saying that he doesnt get billed more than 15-20$ bucks and so on. Little does he understand that i find such things beyond unprofessional , why would i put my personal CC information on AWS that is totally work related. I didnt read once sentence about "worker protection" in cases of crazy billing issues that some people face on amazon etc etc.

Also the whole atmosphere feels a little bit weird i would like to avoid making a bad impressions right at my first days there , but i havent been this anxious for a very long time.

Im i really being too sensitive and i should play this along with them or should i write a nice message to my CTO explaining it nice as possible and seek for another way to resolve my situation ? I could be totally wrong but this really shocked me to the core and i view it as extreme red flag if i could have seen that setup guide before iv singed the deal i wouldnt even do it.

Appreciate any sort of input i felt like this is the best place to post since i guess many of you work on AWS and understand the billing process and everything else.

Founders/entrepreneurs: Help is needed over here.

I have already posted about my recent, new, shiny project!

It has a name now: Red Labs Ltd.

We are still collecting feedback from everyone. Our strategy is to get in touch with as many people as possible in this phase and ask for feedback about the website https://www.red-labs.co.uk/ (we want our products/services to be clear to everyone) AND about our future steps.

Future steps:

Step 1. Ask for help and feedback (doing it now).

Step 2. Get our first 10 customers (all the partners are still employed full-time, so we need a minimum amount of revenue to complete the transition aka quit our full-time jobs)

a. How are we going to get the first 10 customers?We are in conversations with ex-directors of different consultancy companies, hopefully, this will give us some clarity.We are going to apply to become both GCP & AWS partners.We have a LinkedIn campaign ready for February 2023We are asking for help from more experienced and business-savvy people on a daily basis.

b. What are we going to show them? We are preparing an MVP.

Step 3. Once we reach our target revenue the transition will be over, which means that we will be able to leave the company we work for.We have decided to leave 55% of the revenue in the company to invest heavily in marketing, 45% should be able to cover our salaries and expenses.

Step 4. We are reducing expenses as much as possible. Our website cost us 7£ lol and the hosting/email are for free. For the first 4/5 years, we will try not to waste money.

Step 5. Ultimately our goal is to move to a subscription-based model, so we're starting with consulting to build a user base/customers to then create products and make them available via a monthly subscription.

There are going to be 2 subscriptions Standard & Premium.

As soon as we will reach 30 customers (I'm estimating 30% Premium, 70% Standard), we will look into expanding the company, hiring more people or looking for a buyout.On top of this, we will keep doing consulting, if there's going to be the time or possibly hire 1/2 people to do it while we manage the subscription-based customers.

\-------

This is a high view of our optimistic plan. Things might go wrong, we know that (particularly with one of the biggest recessions starting) but it's worth the risk.

Thoughts???

We made a free CICD/deployment tool: initializes your gitlab repo, installs dokku and your app on your server, deploys your app from gitlab to your server, sets your domain and establishes continuous deployment so that all main commits are automatically deployed. Templates for Django, flask, fastApi

[ezinnit](https://github.com/johnsyncs/ezinnit)

Automated CICD Deployment Utility

Continuous integration means that from the moment you begin your project, frequent commits to main are automatically deployed. Continuous deployment means that from the moment you begin your project, you always have a live build of your app in a container on a remote server with a secure public connection.

After running ezinnit, your webapp will be running on your server, live at the https domain of your choice and future commits to your main branch will automatically deploy to the live app.

In a completely automated process, ezinnit initializes and pushes your gitlab repository and deployment pipeline and then installs dokku and a gitlab runner on your server. Your gitlab repository is configured to automatically deploy any commits to your main branch to your server, where your app is automatically built in a container and served at your public https domain.

ezinnit includes app templates for new django, flask and fastApi projects. These templates are intended for starting completely new projects, and create a deployed, working site.

to download and install ezinnit:

in your project's root directory, run:

`mkdir ezinnit wget https://raw.githubusercontent.com/johnsyncs/ezinnit/main/ezinnit -P ezinnit bash ezinnit/ezinnit`

You will be prompted for:

1. gitlab username
2. gitlab domain (if your account is with gitlab.com, then the gitlab domain is gitlab.com)
3. [gitlab personal access token](https://github.com/johnsyncs/ezinnit/blob/main/other/the_old_way/tutorials/link_to_gitlab_and_dokku/get_personal_access_token.md)
4. app name (also becomes your gitlab repository name)
5. ip address of your remote server
6. the domain or subdomain you wish to point to your new app, for example: mynewapp.mydomain.com
7. email address to use for registering with [letsencrypt](https://letsencrypt.org/)
8. optional app template: django, flask or fastApi

requirements:

* a python virtual environment with your app installed (or to make a django project from scratch, see bottom of readme)
* git
* a gitlab account (gitlab.com accounts must be verified to use gitlab runners, but verification is free)
* a server running Ubuntu 18.04/20.04/22.04 [how to create a digital ocean droplet](https://github.com/johnsyncs/ezinnit/blob/main/other/the_old_way/tutorials/digital_ocean_tutorial/create_digital_ocean_droplet.md)
* your local machine's ssh key registered on gitlab
* your local machine's ssh key added to your new server's allowed hosts ([digital ocean tutorial](https://github.com/johnsyncs/ezinnit/blob/main/other/the_old_way/tutorials/digital_ocean_tutorial/create_digital_ocean_droplet.md))
* for your domain to work, you need a DNS "A" record pointing your domain to your server ip address [(create the DNS "A" record before running ezinnit)](https://github.com/johnsyncs/ezinnit/blob/main/other/the_old_way/tutorials/link_to_gitlab_and_dokku/point_url_to_dokku_app.md)

warning!

* this script creates new ssh keys on the remote server!
* if you select an app template, ezinnit will write over files, including your procfile, settings.py, main.py etc. Only use the templates for brand new projects.

what ezinnit does

* checks for ezinnit.config, if it doesn't exist, it prompts you for the values and creates an ezinnit.config file
* if there is no .gitignore in your project directory, uses [toptotal](https://www.toptal.com/developers/gitignore) to create a .gitignore file
* runs app template script if you've selected one (django, flask and fastApi are included in this release)
* creates a gitlab pipeline for automated deployment (.gitlab-ci.yml) in your project directory
* if there is no requirements.txt file in your project directory, creates a requirements.txt file
*
