Professional over thinker doing a job interview

Hello, so recently i applied to a DevOps engineer position as a joke with friends. I actually have a decent background on both for someone who hasn't been highered yet. I got this test, where i have to make an automated currency converter that uses an intermediary currency, so if the user selects USD to EUR, i have to do something like this USD -> MXN -> EUR. Every decimal point after the second decimal point is "mine" to keep. But i also have to find which intermediary is the best for the customer and which is the best for me.

I finished the projects in around 3 hours, with bug fixing taking about 45minutes and searching for a good API took about 30minutes. So in total i spent time codin was around 1.75h? It's around 60 lines. A friend said he wouldn't use any imports except the requests import, to show skill. Currently I'm importing math (only for trunc() function) and pandas and IPython.display to create the table and display it in the console, since for somereason pandas style function didn't work.

Is it better for me to not use imports to do it, or is it better?

To people asking why I'm doing the test, its because I'm bored at home and like a little challenge.

https://imgur.com/a/mpP367o heres a view of the code. I haven't taken the time to make it look better yet, since i decided to hit the hay once i got it working properly.

Need help with career decision!

Currently I'm working as a junior cloud engineer (Azure) with 9 months of cloud experience and a overall professional working experience of 2+ years.
The reason I'm looking for a switch is, my company decided to shutdown the cloud dept as it was a startup. Currently serving my notice period.
I have worked on couple of projects and have to knowledge of Azure DevOps, ansible and gitlab.

Should I look for a switch in DevOps or look for a similar job opportunity?

Please share your view.

Digger - an open-source Terraform Cloud Alternative (Now in Golang)

Digger is a Github Action that runs Terraform plan and apply with PR-level locks. The idea is that terraform jobs run natively in your Github Actions - no need to share sensitive data with another CI system. There's no need to deploy and maintain a backend service either. We migrated from Python to Golang yesterday. None of the team had experience with golang, but we managed to migrate in a week. Here's why we did it:

* Faster runtimes (upto 30x faster)
* Can be compiled into single binary, advantages for Github actions is that we don’t need to wrap action into Dockerfile.
* Easy to compile binary to multiple platforms, it helps us run from same codebase.
* Interface based development , more guarantees about the code correctness by the compiler when compared to using Python.
* Golang is more popular in the DevOps and infrastructure community, we can find several libraries and reuse them in our code.

Here is the link to the repo - [https://github.com/diggerhq/digger](https://github.com/diggerhq/digger).

Seeking feedback from the community on how our code quality is. Please be as critical as possible! :)

Any tool to automatically containerize Jenkins jobs for future use in other tools?

So, I've heard about Dagger.io, but it's not gonna work out for me. The thing is, I've got a heck load of old and established jobs on Jenkins. Now, what I'm wondering is if there's some awesome tool or trick out there that'll let me put those jobs/stages into containers, so I can run them on a different platform without any hiccups?

Any good online text editors?

I'm getting so lazy I don't even want to have to open an application for basic text editing :) Something that loads up from a link without logging in and has basic find and replace, maybe line join and even regex find and replace.

I have been using https://onlinenotepad.org/ but I wondered if there was something that offers slightly more functionality and doesn't look like it was made in 2003.

Elite vs. Low Performing DevOps Teams: How good is your DevOps team?

How good is your DevOps team? You can find out where you stand on the software delivery performance scale - elite, low performing, or somewhere in between. Vote below, and let's see where we all stand. Let's together have an open discussion about the #DORA Metrics. Let's see if these metrics actually empower and enable our DevOps teams or are these metrics just BS, easily manipulatable KPI's for micromanaging teams or is this just good old marketing tricks.

Multicluster Prometheus question

Hello everybody.

I'm in the process of moving our projects from VM to k8s. In our new k8s setup we want to implement multi-cluster, multi-cloud infrastructure. So far, so good. Everything seems understandable and reasonable, except monitoring.

I have never used Prometheus before. Our company used TIG stack with VMs, which we found reliable and easy to use.

So, we need to collect metrics from both clusters. As far as I understood, we need to setup some external service to collect those metrics. I found info about different agents, Telegraf Prometheus plugin, Thanos, Prometheus Federation, etc. But I don't understand, why we can't just connect Prometheus services as backends to Grafana and collect metrics without proxy services? I know that Prometheus is stateful app, so if it goes down, historical data could be lost. For us it is not a big deal, because all necessary metrics we collect and store in external ELK stack.

So what are cons of using Prometheus connected directly to Grafana?

git: 'submodule' is not a git command ONLY when running through Jenkins

I am adding a Windows worker to my Jenkins instance but hitting some issues with Git, this issue occurs when using checkout scm in the pipeline or putting git submodule into a bat block.

I can run any other git command just fine, I can run it as the fully qualified executable path or just git with the same results as well.

Running git --version outputs the same version number and I updated from 2.30 to 2.40 without resolving the issue, but both git --version outputs changed so I think I am 100% running the correct git binary via Jenkins.

I have no clue why or how this issue could be occuring, any insight would be appreciated.

When run via Jenkins:

C:\Jenkins_Workspace\workspace>"C:\Program Files\Git\cmd\git.exe" submodule 
git: 'submodule' is not a git command. See 'git --help'.

When run on the host:

C:\Jenkins_Workspace\workspace>"C:\Program Files\Git\cmd\git.exe" submodule
<listed module here>

Become your own heru?

Hi all! So we've created a platform that enables connecting to any registry, any vm you have and easily deploy infinite Docker apps while connecting each app to a domain. Oh, and we do all the hard wiring without installing any agents! are looking for first users to help validate it.

Job hunt advice

I am a Master's student who is working as a DevOps engineer at a startup.

I will be looking for a full-time job (DevOps, SRE, Platform engineering) later in the year.

Just wanted inputs on how to look for the above-mentioned jobs. Should I just use job platforms like Indeed or Linkedin? Are there any other techniques that worked particularly well for you apart from applying to job websites?

Thanks.

PS: I am doing my masters in Canada.

Designing architecture for containers where every container is unique in ECS

Hey Devops, been tasked with designing a solution for a containerized application where each container must maintain a 24/7 TLS connection with an endpoint, and having some difficulty thinking through this.

We're migrating what is normally a single container hosted on-prem by the customer to a cloud solution hosted by us. It's my understanding that each container is running the same application but is facilitating a custom integration interface and needs to have access to a set of certificates specific to the customer for outbound traffic. I also need to route to a particular container based on inbound IP.

My difficulty is understanding how to make this scalable. From what I've gathered there is a single task or workload ongoing by each container so these wouldn't(?) be clustered together. It sounds like I would need a unique task definition per customer so we can connect them to the proper volume. We don't really need to scale the amount of containers per customer, but internally we need to be able to scale to however many customers we onboard.

Currently my line of thinking is that we're just going to have a task definition per customer and set an ALB in front to route. Is there a better way to do this that I'm missing?

I'm working out how to handle this and reduce the manual configuration and technical load as best I can. Part of me feels like this might be best suited to just being VMs.

Framework for tool development?

I’m not sure how many of you have cause to develop internal tools, but for those who do what framework are you using? I’ve seen some people using Retool, but it seems somewhat limited in scope. Has anyone ever delved into using something like React for this?

IAM application control security Interview question

Today I had an interview at a big trading firm for cloud dev sec position and one of the questions that I couldn't seem to answer was " how would you implement or design IAM application control if an application needs to use resources from another application or if a user needs to use resources to another application."

I gave the short hand answer of RBAC or ABAC and or MFA and or grant the user the access to the resources. But the interviewer had a really shitty mic and i could barely hear him. Can someone who has experience on this tell me what i should read or guide me in the right direction. I've already tried chatgpt and it gave me very vague answers.

Need Help With Some Perforce Commands

Hey there!

I'm hoping this is the right place to ask these questions, but I'm a game developer using Unreal Engine and Perforce as our source control. I'm having some issues with retaining server space, as our project files are constantly being modified and updated on our Perforce server, and file sizes are snowballing as individual files can have 50-100 revisions.

It's my fault for not tackling this issue earlier, I now know that it is possible to limit how many revisions a file can have with the +sN modifier of the filetype command, but as far as I can tell, this is per file, and would need to be done on each new file added to the repository. Is there a way to set this to automatically be done for every new file? Unreal Engine has their .uasset file type which most project files are stored as, If I was able to tell Perforce to only keep the last 5 revisions of every .uasset file, then that would solve most of my problems.

My next issue is one that I'm not sure there is a solution to, but I'm currently going through our depot in P4Admin and finding files which have huge amounts of revisions and deleting the earlier revisions one by one. And again, I know this is my fault for not setting things up right in the first place, but is there any way through either P4V or the Command Client to select a folder and remove all revisions of every file in the folder except for the head revision?

This would be very helpful as in some of the worst cases in our depot, the total size of just the head revision files can equal around 500mb, but in reality with all of the different revisions of all the different files, the size jumps up to around 10gb!

Thanks in advance for any insight into these issues!
