🎾 Kubernetes pod eviction is PAINFUL 👇

But sometimes, it had to be done.
Okay.

In our story,

we have 3 happy pods on Node-1.

And CPU spikes up high on NODE-1: Now what?

"Kubernetes has a decision to make."
"It must evict a pod."
"Which one?"

That's where QoS classes helps Kubernetes.

At any point, a Pod can have 1 of the following QoS classes:
🔢. Guaranteed
🔢. Burstable
🔢. BestEffort

When a Node is under pressure,

Pod with BestEffort QoS takes priority for eviction.
Burstable next.
Guaranteed last.

Unfortunately, Pod3 has BestEffort QoS.
So gets evicted first.

Happy endings though. Pod3 gets welcomed on Node-2 ☺️

🎤 Frequently Asked Questions ‼️

🔢. How to become a DevOps Engineer?
➡️ To become a DevOps Engineer, you need to have technical skills in areas such as development, automation, containerization, cloud, CI/CD pipelines etc. Some sample tools and technologies to learn may include any programming language, AWS, Ansible, Terraform, Docker, Kubernetes, Jenkins, Git, and monitoring and logging tools. Gain experience by working on DevOps projects, develop a DevOps mindset, get certified, and apply for DevOps Engineer positions by highlighting your skills and experience in your resume.

🔢. What are some misconceptions about DevOps?
➡️ Some common misconceptions about DevOps include:

🟢 DevOps is just automation: While automation is an important part of DevOps, it's not the only thing. DevOps is a culture that emphasizes collaboration, communication, and integration between development and operations teams to improve the quality and speed of software delivery.

🟢 DevOps is just a job title: DevOps is a mindset and set of practices, not a specific job title. Anyone involved in the software development and delivery process can adopt a DevOps mindset and apply DevOps practices in their work, including developers, testers, operations engineers, and others.

🟢 DevOps eliminates the need for IT operations: DevOps does not eliminate the need for IT operations. Instead, it changes the way that operations teams work by promoting collaboration with development teams and introducing new tools and processes for deployment, monitoring, and maintenance.

Issue: A critical service experiences an outage, impacting users and business operations.

😀 Resolution:

✔️ Incident Response: Quickly activate the incident response plan to diagnose and address the root cause of the outage.

✔️ Rollback Plan: If possible, execute a rollback plan to restore the service to a stable state.

✔️ Failover and Redundancy: Implement failover mechanisms and redundancy to minimize the impact of single points of failure.

✔️ Monitoring and Alerting: Enhance monitoring and alerting systems to proactively detect and respond to potential outages.

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

🔴 Scenario 2: Cross-Functional Collaboration

Issue: Communication breakdowns between development and operations teams lead to misunderstandings and delays.

😀 Resolution:

✔️ Cross-Functional Teams: Foster a culture of collaboration by having mixed teams with members from development, operations, and other relevant departments.

✔️ Shared Tools: Use tools that are accessible and understandable by both developers and operations teams.

✔️ Continuous Communication: Encourage regular meetings, stand-ups, and knowledge-sharing sessions to align goals and expectations.

✔️ Blameless Post-Mortems: Conduct blameless post-mortems to analyze failures, identify improvements, and avoid assigning blame.

𝐄𝐫𝐫𝐨𝐫:📁 File not found
𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧: 🧐 Verify file location and name. Use the ls command to list files in a directory.

🎮 Integrating Ansible and Terraform can provide a robust IaC solution


1⃣ - Install Ansible: Ansible is written in Python and can be installed on most operating systems with ease.

2⃣ - Create Inventory File: Make an inventory file to identify the machines that Ansible will manage.

3⃣ - SSH Keys: Ansible communicates with machines via SSH. Configure passwordless SSH connectivity by setting up SSH keys.

4⃣ - Run Ad-hoc Commands: For example ansible all -m ping

5⃣ - Write an Ansible Playbook: For complex automation tasks, you'll use Ansible playbooks.

6⃣ - Run the Playbook: Use the ansible-playbook command to run the playbook.

7⃣ - Install Terraform

8⃣ - Initialize a Terraform Directory (terraform init)

9⃣ - Create a Terraform File: Write a .tf file for your infrastructure.

1⃣0⃣ - Apply Terraform Configuration (terraform apply)

🌟 Azure vs AWS vs GCP

Lately, I've been noticing a surge in discussions comparing different cloud services across various providers.🌩🔍

It sparked my curiosity, and I thought, "Why not create my own comparison?" 🤔

So, after diving deep and gathering insights, I've put together my version. 🚀
