Why redirect stderr to dev/null?

I recently started working as an Infrastructure Engineer and looking at the script files I often see this line: 2>/dev/null. What is the purpose of discarding errors? I thought errors should always be handled instead of being discarded.

Need code wrapper for failing code

Hi DevOps. I need to create a code wrapper that will call failing code a number of times. So far, this is what I build. Let me know if I am missing something or you have a better alternative.

#!/bin/bash

function runx() {
  RESULT=1
  for ((n=0; n<4 && $RESULT != 0; n++))
    do $@
     RESULT=$?
     if [ $RESULT != 0 ]; then
       echo "error in[$n]: $@"
       sleep 1
     fi
  done
}

# For test:

runx true
runx false

My result:

error in[0]: false
error in[1]: false
error in[2]: false
error in[3]: false

Red Hat: A waste of money or worth it?

Hey All,

Thought I’d gather some opinions around Red Hat licenses and if anyone think they are/aren’t worth it.

For context one of our infrastructure team came out with a line “Red Hat enterprise Linux is a complete waste of money, we may as well just use centos or Ubuntu and save thousands a year”. Having never used Red Hats support I was curious as to what benefits you actually get paying for RHEL.

Similarly, Ansible tower is on the face of it a repacked version of the open source awx. Ansible tower is also full of feature requests which are waiting on the awx project to implement so why would one pay for a license when you effectively could get all the functionality for free? The only reason I can think of is certain organisations like access to vendor support.

Help with Interview Assignment

Hello Guys,

I have been given a take-home task for a devops role and I feel that I need a bit of guidance/help. I've been unemployed since July 2020 and I really need this job before my unemployment runs out. I've already started it, but I feel stuck and can't seem to find the right material, most likely due to lack of experience. i

If anyone would be willing to offer some guidance I will be eternally grateful. I am desperate and really need this job. Thank you!

Cheers,

Hosting .Net core + React + SQL on azure

Hey,
I am going to host both static react websites and .net core + react + sql apps for multipe different clients and i need an explanation about how to perform the infrastructure.

I want to do so with azure and i have few questions:

1) Where do i host it? I searched and seen many answers (Create vm, host as web app with azure devops etc.)
Are there any good tutorials for that matter? I am running the react app from within the wwwroot of the api on the same port the api runs in (I am going to run multiple apps).

2) What is the estimate price for hosting a static react website?

3) What is the estimate price for hosting web app with both react, .net and sql?

Learning about Dev Ops, and need some clarification.

Our company is currently undergoing changes in leadership, and it seems Dev Ops is going to be a focus going forward. I've gone through a few hours of training on Dev Ops independently now, and I'm wondering if I'm misunderstanding something, the training I've gone through is unclear, or if I'm just missing the point. I'm hoping some of the people here can clear up some of the misconceptions I'm sure I have from the training I've taken:

1. The first thing I'm seeing is a focus on streamlining and automating workflow whenever available. As a Sysadmin I feel like I already do this, writing scripts to automate both my own workflow and the workflows of other teams and developers when I become aware of pain points in their processes. Is this already a preliminary step towards Dev Ops culture, or am I misunderstanding?


2. I'll be honest - a lot of the training I took just seemed like "corporate buzzword soup." Beyond organizing teams that are responsible for a project from start into perpetuity and streamlining/automating processes wherever possible, are there any core concepts I should be aware of?


3. The training I took strongly stressed teams that work closely, working together and collaborating on every step of a project on a practically constant basis, and that people who worked better on their own were detrimental to a Dev Ops culture. I'll be honest - this struck me as a bit discriminatory towards team members that may have been diagnosed with social anxiety or generalized anxiety disorders, and may require significant time away from others in order to function in their job role. How can a company adopting a Dev Ops culture provide these team members with reasonable accommodations as required under the ADA?


I apologize if these questions seem overly critical, I am just trying to understand how we can best adapt to and function with the changes to come.

How do you store your helm charts?

My last gig we just stored the “raw” helm yaml files (not the chart.tgz) in gitlab and we didn’t bother with packing them and storing them in artifactory since all of our charts were internal. I’m at a new gig now and we’re trying to figure out how to store and organize our helm charts. Is there any benefit to pack our helm charts and store them in something like chartmuseum if we’re not planning on distributing them?

Suggestions on web interface for inserting values into a YAML document

Looking for some ideas on a good approach to solve this. I have a YAML document that describes some stuff. I can use JINJA2 syntax in it to dynamically insert values. I want to build a web interface that a person can access, be presented with a form, and when they click submit, they are given the completed YAML document with their entered values inserted. (Alternatively I may store the document and send it somewhere else later). Bonus points if it can run serverless on Lambda :)

Just looking for some suggestions on approaches to this, or maybe some resources that I can review. Thanks in advance!

Prometheus Alerts using Grafana vs AlertsManager

Hello Community,


Need guidance on setting up the alerts using alerts manager vs Grafana inbuilt alerts mechanism? What are the pros and cons of using Grafana to set the alerts vs using the alert manager config file directly? I am doing a POC on this and would need help from the community here based on your expertise and experiences.


Thanks,

To Devops Professionals - What industries do you work in?

Hello World!

I'm conducting some market research and would like to ask devops professionals:

1. What region of the world are you based?
2. What industry vertical do you work in?
3. Is your dev team empowered to source your own devops tools to get the job done?

I want to find out what non-traditional industries are adopting devops practices successfully and whether they foster a sense of developer empowerment. Any thoughts would be appreciated!

Thanks!

EMPTY FILE IN GITLAB ARTIFACTS

Sorry if this is the wrong subreddit but I'm having an issue with Gitlab artifacts. We're trying to get test coverage written to a XML file as an artifact. We have marked tests split into two pipelines.

Build:
stage: Build
script:
- *setup-build
- *build
- touch banana.xml # where I write the code coverage collected by pytest-cov
- *push
artifacts:
paths:
- banana.xml
reports:
cobertura: banana.xml

Unit Test:
stage: Test
script:
- *setup-build
- *pull
- docker-compose run $DOCKER_IMG_NAME pytest -m unit --cov-report xml:banana.xml --cov=app --cov-append;
needs:
- Build

Validity Test:
stage: Test
script:
- *setup-build
- *pull
- docker-compose run $DOCKER_IMG_NAME pytest -m validity --cov-report xml:banana.xml --cov=app --cov-append;
needs:
- Build

After the Build and Test stages run, I go to download the banana.xml file from Gitlab but there's nothing in it, even though the jobs say `Coverage XML written to file banana.xml`

Am I missing something with how to get the total coverage written to an artifact file when splitting up marked tests in a gitlab pipeline stage?

How's your experience with Pulumi?

I have been playing around Pulumi for a while and I have a couple of questions for DevOps developers and for Pulumi users specifically, I hope you don't mind answering them.

What are the challenges that you faced working with Pulumi?
Would you change anything in the tool if you have the power to do so?
Are there any pain points using the tool?
Thank you for your time.

CircleCI strikes back again: hide per-user charges

Recently, I've decided to review our billing statements on CircleCI and discovered that the user payments disappeared. I was really surprised because when I complained about it to their team earlier this year, I was told that it is not going to change.

I went to their pricing page but it still stated that they charge per active-user. It took me a couple of minutes to find this post: https://discuss.circleci.com/t/performance-plan-billing-update/39502. In short, they hid the per-user charges by mixing it with the charges for running build jobs such that now it is harder to tell how much you are paying for the users. It is still trivial to compute it but it is not visible on the invoice anymore.

This per-active-user charges always annoyed me since we upgraded to Performance plan. It is basically allows them to grab more money from their customers claiming lower costs on their pricing page. They even charge you for a system user triggering "cron" jobs. So you are paying $15/moth for using the "cron" jobs feature. For us, the per-user charge reaches almost 50% of the total bill on an easy month so it is a significant part of the total charge. Hiding it in the invoice seems to be a dirty trick.

Anyhow, I would like to renew the discussion started on https://www.reddit.com/r/devops/comments/d3sqr0/whats\_your\_experience\_moving\_away\_from\_circleci/. What are the best alternatives to CircleCI in 2021?

Migrate from Heroku, Postgres, MongoDB to local server

I had made an application which was running a React frontend on Firebase, Django backend on Heroku, and using MongoDB & Heroku Postgres as database. As I was using Free Tier of all these services, I was approaching their usage quotas.

My university recently allotted me a bare linux machine (with generous specifications) which I could use for hosting my app. I've received SSH credentials for the same. Can someone advise me how I should go about the process?
