Issue tracking for open-source projects

I have an open source project and we manage release planning in jira, but managing 2 repositories for issue tracking is cumbersome. Is there a way I can overcome this. How do open-source projects generally manage their issues for every release cycles ??

Guide to cracking interviews from insiders?

I have been in the process of doing interviews for Devops roles and been having mixed success. There are many rounds to even get to the onsite but typically hit a brick wall.

I seem to get picked by HR managers as my resume has the key words (buzz words use to screen) and then do countless calls set up by recruiters.

For the assessment, I do technical tests and for the most part my answers are right, but the managers are so picky that even if you answer is correct you don’t get selected. The questions they ask are not super hard. Most frequent URL from a file, ping IP addresses in a loop, replace a word using sed command. I ask is this correct, and you here the usual (we’ll get back to you).
There doesn’t seem to be any objective standard and it seems very arbitrary. Do you want me to write the code first time right without any errors? Did I take too long?
(You get a typical thank you applying while we were impressed , by your evaluation we have decided to move on.. yadda yadda .. very impersonal and no sort of helpful feedback.


When I go onsite, they start asking me super curve ball questions and sometimes obscure out of left fields. I’m not a networking guy.. yet they ask me What port is SNMP, what is difference between router and a switcher, what level are they on? And nuances between Entrypoint and CMD? And what are inodes?
The worst is when you are expected to memorise command line functions such as using stat or how to sort logfile and knowing the right arguments.

Things you usually look up on Wikipedia as I don’t memorise the documentation. Then I do white boarding and draw my setup - it’s a Kubernetes cluster with pods running micro services. Then would you make this multi regional or zonal, are you using VPC peering?
Basically I have to explain the architecture and theory behind this as If a lecturer, I’m a practitioner of tools

I am bewildered as how to play this game. I miss some super easy questions (such as what’s the docker process running in background- dockerd ..how do assign Kubernetes pods to nodes ..using labels). Obviously I try to go prepared but you can never know what they are going to throw and it you.

The recruiters are horrible and pitch you to get their quota, sometimes they even send the wrong job description and make appointments without your permission. Obviously they don’t want to gamble and make the wrong decision on a hire, the managers though are the real ones in charge and decide if they hire you. And it’s not easy to get past them.

Obviously I know this whole process is a vetting out competition trying to weed out weak candidates, but at least make it skills based and something you will do on the job. I can make a CI /CD pipeline, set up a cluster , do automated deployments all day, set up monitoring tools.

But asking me what is a replica set and deployment difference ( trick question ) .. they are the same.. or what is Kubernetes operator? It starts becoming more a sadist ritual on trivial jargon that an evaluation of your competence.

Sometimes it seems like companies don’t know what they want - or they send the wrong message about their company. Are they trying to measure ability or the persons ability for cultural fit? I’m even afraid to answer the right answer, as they will follow up with a bunch of even harder questions until I choke. I start thinking the Gods of tech are cursing me and delighted in making me look very foolish ...

I’m starting to think who these guys hire because it’s the unicorn who uses their exact tech stack, needs zero training, and subject matter expert in several domains with exceptional knowledge of system architecture.

I’m not trying to make light of a job selection process as it’s challenging, personally believe it’s about compromise .. if person suffices and satisfices rather than creating a mythical tech worker based on a checklist.

How to pass a variable from a Root Module down to a child module? Terraform

I'm not understanding the usage of Output Variables correctly or something ... the documentation is confusing and I can't find examples online.

Structure:

|- /api/datasources

|--------------------- dev.tf

main.tf

I understand how to broadcast the output, but how do I consume it from the child element?

namely ... SSM parameter value..

-----------------------------

module "transfer" {

source = "./api/datasources"

api_id = "${var.api_id}"

}

--------------------------

output "api_id" {

value = data.aws_ssm_parameter.myapi.value

}

------------------

The child module (datasources) needs to consume the output of this ... but HOW DO I pass it thru the module?

How do I consume the api_id inside of /api/datasources/dev.tf?? Here is dev.tf:


---------------------
resource "aws_instance" "name"{

api_id = var.api_id

}
---------------------

Help... please

Falco vs OpenShift Security Constraints

Hi!

Does anybody knows the main differences between these two alternatives regarding security on Kubernetes? I've found no paper/video explaining it. What do you use on your day to day and how is your experience with it?

DevOps or Agile?

Is DevOps a part of Agile, or is Agile a part of DevOps? Are they different things all together? SAFe believes DevOps (CI/CD) is part of overall Agile. I’ve heard and used both terms as parts of each other and their own items. I find it depends on the audience. This sub seems to be mostly focused on the technical pipeline piece of DevOps. Is that the “right” definition?

Maybe they’re just buzzwords with no clear definition...

How to move to using infrastructure as code / configuration management / devops tools in a monolithic environment?

Old school sysadmin here, and I am struggling to find a value add that I can use as a justification to start such a project in a windows environment. The idea of ansible/chef/terraform sound amazing, but we already have tools to do most of the things I read about and none of them require messing with YAML or learning python. We are still buying software from vendors that are struggling with the concept of virtualization & server core let alone stateless containers. We don't do much in-house dev work and most of apps are typical 3 tier (SQL/APP/WEB). So, where could I find value with these tools?

How do you folks implement load shedding?

A common recommendation for running high availability systems is [load shedding](https://aws.amazon.com/builders-library/using-load-shedding-to-avoid-overload/). Last year I personally experienced an outage that was exacerbated by a lack of load shedding. I can find a handful of resources talking about this strategy but none touch on the practical aspects: Okay, I want to implement load shedding, how do I do that? What software can I use?

I've been using HAProxy as a reverse proxy in front of my application, which [has some queuing features](https://cbonte.github.io/haproxy-dconv/2.1/configuration.html#timeout%20queue) that I was able to work into a primitive load shedding system. Unfortunately, I'm going to have to move away from it (or pair it with nginx or similar) because HAProxy [doesn't support request buffering](https://www.mail-archive.com/[email protected]/msg23074.html).

Wondering what everybody else's experience is with this.

I wrote a self-hosted slack bot that will notify you when you are mentioned in on GitHub projects or Organizations in Lambda.

GitHub project: https://github.com/bagel-dawg/github-slack-mentions

I was tired of having to check my email to find out if my username was mentioned, or if my PRs were approved/commented on. It also has the ability to remind you daily of any notifications that are still on-going.

The reminders functionality assumes it will be used with an organization, but the mentions functionality will work with standalone repositories OR organizations.

It is based on AWS API Gateway+Lambda integration proxy and DynamoDB with 2 indexes for key+value storage. It can be deployed manually, but there is also a serverless.yaml for convenience.

What’s the value of CI with Jenkins?

I’m new to Jenkins and I took a look at a build log and it appears to download and install all package requirements for a job every time it runs. If there are a ton of jobs that runs hourly, wouldn’t downloading and re-installing it take more time, bandwidth and processing power? Why wouldn’t one just have it run as a cron job with all dependencies already downloaded and installed?

What administrative process is involved when your company decides on adopting a new tool or tech?

I'm sure answers will vary. Some companies are very ad hoc, some have a team that considers new tools. How does yours operate?

When is a DevOps Engineer's day?

Hi y'all!

Some days ago I was interested this little question. Because the developers have their professional day as well as sysadmins, web-developers and QA-engineers. but nowhere I found any mention of DevOps Engineer's day.

Does somebody know when we may celebrate this day?

Whats wrong with Jenkins?

I've been learning up on the various CI/CD tools (there are so many!) and every discussion I see on here, people are avoiding Jenkins. I'm I big fan of the CloudBees podcast, but haven't tried Jenkins yet myself.

Currently I'm using CircleCI, GCP Cloud Build, and AWS CodePipeline. I'm also just starting a Travis CI experiment.

Whats wrong with Jenkins?
Is it worth learning for my future projects?

Build logs and secrets

How do you prevent a commit someone made causing secrets in a CI system getting leaked to build logs.

Most CI systems have a way for you to describe the CI steps within the repo. This can be as simple as someone creating a PR with the following:


commands:
description: "This is needed to run the build"
steps:
- run: python -c \"import os; print(os.environ['SUPER_SECRET'])"


Some CI systems know to filter build logs for secrets they are aware of but this doesn't particularly prevent someone from exfiltrating it.

commands:
description: "Save this important secret so I don't lose it"
steps:
- run: ./http_exfiltrate_secret.sh


There appears to be different strategies and tactics for preventing this, but I'm wondering what strategies there are if you have a monorepo/ consolidated repo where both the CI and the application are described.
