Best courses to learn python specifically for devops

I am doing sysadmin things in my organization and I've heard everywhere that one cannot survive in devops without scripting knowledge either bash or python.
I know neither of them but want to learn one and picked python first. I don't want to learn in deep or i don't know if i should learn it deep.
I am from a non technical field just entered into the software industry so it'll be quite hard.
Is there any courses where can I learn python specifically for devops? Like for automation and scripting. I've heard that automate the boring stuff with python is good but would that be suitable for me as i am from non tech field and have low critical thinking ability? What are your recommended courses and what's your advice for me?

Monitor Logs From an Agent in Icinga2

I'm currently using Icinga2 for a distributed monitoring solution, in a master-agent configuration. I've looked into using the built-in logfiles plugin ([https://icinga.com/docs/icinga-2/latest/doc/10-icinga-template-library/#logfiles](https://icinga.com/docs/icinga-2/latest/doc/10-icinga-template-library/#logfiles)), but have found no success in getting it to parse through the requested logfile on the agent server.

Here's the curent configuration within \`/etc/icinga2/zones.d/master/cpanel.conf\` on the master server:

object Service "cpanel-backup" {
import "generic-service"
host_name = "cpanel29.dbl-mail.com"
check_command = "logfiles"
vars.logfiles_logfile ="/var/log/borgbackup.log"
vars.logfiles_critical_pattern = "error:"
command_endpoint = host.vars.agent_endpoint
}

Any ideas on what I'm doing wrong?

Scaling RabbitMQ

Hey guys!

Currently facing the use case where our RabbitMQ cluster (3 nodes, all quorom queues) has to handle 80k-100k events per second. We've reached situations where the latency was above what we can allow for our applications and downstream users.

The cluster is being used across the entire company and we were trying to think of ways to overcome this problem.

One of the suggestions is multicluster RabbitMQ where several clusters would be provisioned for different teams so that an outage of a cluster doesn't influence many functions. However, currently we're in a situation where certain teams are producing to queues which are consumed by other teams. Additionally, we don't want to overcomplicate the management of connections to several different teams on the application level and therefore we were debating whether federation is a good use case for this.

If anyone has experience with similar problems or how to spread the load of a RabbitMQ cluster and has any best practices/ recommendations I'd love to hear those and would be very appreciative.

Thanks!

Check application environnement status / requirements

Hello,
I am looking for a tool, an app that would allow me to check the status of an application environment.

I'm thinking about network resources (API endpoints, internet, databases, smtp servers, etc....

In practice, I currently have to check accessibility to +150 resources (URL, domains, host, port ...) and i repeat this check with every change 😮‍💨....

Before I start writing an application, I would like to have your feedbacks. Thanks all for sharing your experience.

How to set DKIM signing key length and DKIM signature with boto3?

Hi,
I am trying to implement Python script with boto3 for aws ses. What my target is, I will create domain identity and it will set DKIM signing key length and Enable DKIM signatures. And then in the console, it will publish the DNS records for DKIM authentication. Anyone can help?

Any recommendations for CLI wrappers?

I currently have a makefile with a bunch of kubectl, helm, and aws commands for various environments. This is pretty ugly / brittle as the commands are duplicated for each environment, and I'd like to be do something like `<something other than make> apply_xyz -env staging`or `<something other than make> apply_xyz -conf ./staging.yaml`.
I recall seeing a CLI wrapper project maybe half a year ago from a DevOps influencer type that looked promising, but I can't recall who it was, or what the project was called.

Does anyone have any suggestions? I'd rather a more basic wrapper, vs doing my own in with fabric, etc.

DevOps redirected to "study" work for AI project

Hello guys,

I need some help/hints for the following ticket since i am kinda confused. I used to work always as sys admin or DevOps but since there are no more projects they ask us to do "study" work and contribute on confluence pages for a AI project.

So they ask us this:

Complete a comprehensive analysis of all the network planning (cellular and non-cellular) software landscape, listing all tools used and categorising them by logical criteria (tbd based on analysis) but inclusive of market share.

Examples: Atoll / ABWave / Etc.

&#x200B;

&#x200B;

I dont have any idea about this type of IT since it was never in my job listing so i am trying to figure out how i should approach it...I checked Atoll but still i am not sure i make much of sense and if this is enough...

How important is Software Craftsmanship at your work ?

How much care your company puts into developing software ?

Do they follow best practices, make sure to properly plan and prepare everything, create documentation, design papers, testing strategies, code quality gates, technical dept management, give development enough of time to create proper solutions.

How many companies even stay adamant about the way they produce software over the years ?

How many of you heard about Software Craftsmanship ? Does anyone even follow the manifesto at work ?

GHA/ADO - Manual deployment of YAML pipeline to multiple environments - single pipeline with env selection vs separate pipelines per environment

GHA = GitHub Actions, ADO = Azure DevOps

Assuming I have 3 environments, dev/test/prod.

I use trunk based development. After every commit to the trunk, CI pipeline is run to build artifact & upload it as pipeline artifact. CD pipeline for dev environment is then automatically run when CI finished. This CD pipeline deploys only to the DEV env.

TEST and PROD deployments are manually triggered in our case right now. Also DEV sometimes has to be manually rolled back to previous artifact.

In case of manually triggered pipelines would you prefer to:

1. Have separate piplines for separate environment - like deploy_dev.yaml, deploy_test.yaml, deploy_prod.yaml. They can be parametrized by variables inside YAML template. Templates can be used to not repeat everything yet pipeline using templates would still be duplicated in some way.
2. Have single pipeline with Azure DevOps environment as a parameter - when triggering we can selecct whether to deploy specific artifact to dev, test or prod. Everything which needs to be parametrized can be parametrized via library group (ADO) or environment vars/secrets (GHA).

Why don't I use single multi-stage pipeline with stages for all environments? Because in our case deployments to test and especially prod environments are not really automated and Azure DevOps doesn't provide great support for manually triggering stages in multi-stage pipeline (they did with classic release pipelines).

I have seen both approach and I do not have a strong opinion. But I lean towards second option.

What are your thoughts?
