Overwhelmed with information

This is geared towards senior devops and people with experience hiring devops positions. I’ve been in IT for just about three years I have a degree in cyber security, and I want to move into a devops position. Currently I am an IT coordinator for a small firm. I have my AWS solutions architect associates Certification and also learning terraform and Git.
What are some hands-on projects that would get me hired for junior level and above the devops positions?

Managing multiple secret keys in CI/CD tools

Typical CI CD process involves lots of heterogeneous tools Jenkins , Git , Sonar , GCP cloud build , Docker reg etc.

In a given process all these tools should be communicating/integrating with each other.

To enable integration there are tokens, secrets to be managed across multiple tools.

As a best practice these tokens need to be managed and rotated safely. I always noticed managing these keys and rotating them is a manual process. Are there any tools that will allow to manage keys and rotate them , secure them effectively after a one time setup across every tool ?

crond isn't running unless I ssh to the container

This is my Dockerfile

​

FROM php:7.4-fpm-alpine

COPY / /var/www/

RUN apk update && apk add php libraries ..

WORKDIR /var/www

# add the crons
RUN mkdir /etc/periodic/minutely
COPY docker/crons/minutely/crons.sh /etc/periodic/minutely/crons.sh
RUN chmod -R 0755 /etc/periodic/minutely
RUN chmod +x /etc/periodic/minutely/crons.sh
RUN (crontab -l 2>/dev/null; echo "* * * * * cd /etc/periodic/minutely && sh crons.sh")| crontab -
RUN crond start

EXPOSE 9000

​

This won't start \`crond\` but if I ssh to the container after it starts running and run `crond start` again, everything works fine, why?

Set hostname in Dockerfile

There's an API we use that raises docker containers and it doesn't allow us to start container with specific hostname (-h hostname123). The only thing it accepts is a dockerfile.

Is there a way to have the Dockerfile set a specific hostname? It stops from something else to work

If you're curious why I'm asking:

> (we use SGE, and I'm building a container that would be able to submit jobs. SGE only accepts specific hostnames, and doesn't allow wildcards. It only accepts jobs that are sent only form a static list of full hostnames. For testing, I started a container with -h hostname123 and it did work)

Github actions + PM2

Hi.

I'm trying to deploy Nest.js app with help of GitHub actions and PM2. In workflow logs, I can see that the app was started (as root).

[PM2\][Initialization\] Environment variable HOME (Linux) or HOMEPATH (Windows) are not set!

[PM2\][Initialization\] Defaulting to /etc/.pm2

[PM2\] Spawning PM2 daemon with pm2_home=/etc/.pm2

[PM2\] PM2 Successfully daemonized

[PM2\] Starting /root/actions-runner/_work/_tool/node/16.5.0/x64/bin/npm in fork_mode (1 instance)

[PM2\] Done.

┌─────┬─────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐

But when I ssh to the VPS and run pm2 ls command, I can't see anything.

Any help would be appreciated.

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?
