Kubernetes Another Class - Sprint 1, 2 (#PracticalBasics #Installation #Deployment #Jenkins #Helm #ArgoCD)

📢 Finally Open! [Practical CKA Certification Perfect Preparation Course]

​

Hello! I'm Ilpro 🙂

Happy New Year 2026!

​

Starting with a proposal from the Inflearn manager last November, the CKA (Certified Kubernetes Administrator) course, which I have been planning, reinforcing, and refining day and night for four months, has finally opened 🎉

If this were a course simply for memorizing exam answers, it wouldn't have taken this long. Let me tell you about the 'three things' I put the most effort into while preparing for this course.

​

1⃣ "Knowledge for the exam" vs. "Real-world practical knowledge"

Many people say that even after getting a certification, "it's daunting to apply it to real-world tasks." This course is structured around the core concepts and the trial and error I experienced while operating Kubernetes in the field. Therefore, it will provide you with the confidence to not only obtain the certification but also play a significant role in actual practical work.

​

2⃣An "infinite practice environment" that feels more real than reality

To ensure you don't panic when you open the exam room door, we have built a practical hands-on environment that is 99% identical to the actual exam environment. Lectures you only watch with your eyes are quickly forgotten. Experience a curriculum where you learn by typing directly so that your hands remember first.

​

3⃣A "high-quality curriculum" verified by students

We have already completed the first round of verification with many participants through the previous Inflearn Challenge ([Before 2025 ends] Let's get the Kubernetes CKA certification! with 1pro). Based on the valuable feedback received during the challenge, we have spent the last two months reinforcing the content and finely adjusting the difficulty level to ensure a seamless learning flow. Now, you will be learning with the most polished final version.

​

Ultimately, this single course is all you need to understand Kubernetes and obtain your certification. 🙂

​

That is why, if you have ever thought about obtaining the CKA certification, I encourage you to take on the challenge this time. I will be there to help you!

​

Thank you.

Free course vouchers will be given to the top 3 participants of the month.

I passed with 89 points 5 years ago. I thought I had solved all the problems without any unknowns, but I couldn't get a sense of where I might have gotten them wrong. A few days ago, I opened the current Sprint5 (Istio edition), and with the mindset of taking a break, I thought about creating a CKA course.

But when I looked at the exam guide again after a long time, there were so many changes;; (Above all, the registration fee...💰💰) I suddenly felt like it wouldn't be a relaxing atmosphere.

And I also wondered if I could quickly help students when I need to retake the exam myself, but the plan is in the link below.

Anyone interested in getting CKA certification together before this year ends?

Hello.

Many of you are already using it well, but for those who don't yet know about bookmark utilization, we're making this announcement.

This includes the Sprint5 Istio course that was recently opened.

• For usage instructions, refer to the link: https://cafe.naver.com/kubeops/142

Hello. It's been a while since I posted an event announcement!

Currently, the 5-month Sprint5 course production is in its final stages.

Since I'm not good at multitasking, I wasn't able to do any other activities besides Q&A during the 3 months I was focused on creating the course.

(I'm really envious of those who create courses and also do YouTube or various SNS activities ^^;)

​

The Sprint5 Istio course is scheduled to open sometime next week, probably around Monday or Tuesday.

We are planning to hold an event for pre-reservations before opening.

​

● How to Apply: [Cafe Event Post]Please leave a comment

● Application Deadline: Until before the course opens (Scheduled to open on November 17th or 18th)

● Benefit Information: After the course opens, a 40% discount coupon will be provided via message.

Hello. This is Ilpro.

The weather has been so nice this week that it's been really hard to work. I'm not the only one, right?^^

Still, I'm preparing hard for the warm-up study that will be coming up soon.

There are only a few days left until the deadline for warm-up applications. I will explain the details during OT, but the approximate schedule for the upcoming period is as follows.

Friday, May 23 - Photo Gathering (Community Usage Guide)

May 26 (Mon) - OT Coach Introduction, Study Progress Method, and Rewards

May 27th (Tue) - Sprint1 study begins!

~~

June 5 (Thursday) - Midterm Review : Knowledge Sharing Challenge Special Lecture (1/2), Q&A

June 9th (Mon) - Sprint2 study begins!

~~~

June 20 (Fri) - Midterm Review : Knowledge Sharing Challenge Special Lecture (2/2), Q&A

Friday, June 27 - Graduation Ceremony

And the part that is currently taking the most time to prepare is [midterm inspection] .

We usually do a lot of Q&A, but the Inflearn manager said that while receiving coach training, it would be good to create a session on anything that would motivate runners to finish the race.

I have often talked about my current work in lectures, and since I am currently devoted to knowledge sharing activities, I will talk about my knowledge sharing activities in two 30-minute sessions. I hope you look forward to it, as I am organizing the content to be as helpful as possible.

PS. To help you progress more smoothly, I have posted some things to do before you start studying . Please refer to them when you have time.

thank you

Hello. This is Ilpro.

The DevOps field was added to the 4th Inflearn Warm-up Club, and I joined. So I am currently busy preparing for the study. The application notice is now up, so I will share the news with the students.

Anyone who has taken the course and participated in the roadmap ( link ) can apply for the study, so I highly recommend it to those who are currently unable to keep up with the progress. The content that will be conducted will be lectures, practical training, missions, and reviews according to the progress chart format I created below.

Of course, the actual studying is done alone, but since we all communicate on Discord, we can increase our will to study by creating an atmosphere where others study together. Below, I have uploaded the OT materials that I am currently preparing, and there are also times when we meet online through OTs and midterms. Above all, there are benefits for doing well in all the courses!

- Application period: May 2nd (Fri) ~ May 17th (Sat)

- Study period: Friday, May 23 - Friday, June 20

- Graduation Ceremony: Friday, June 27th

Hello. This is Ilpro.

It's late, but Happy New Year^^

I have one [news] to share with you.

Some of you may have already read the post in the cafe, but recently Inflearn held a contest for knowledge sharers called [Share Your Knowledge Sharing Experience], and I took this opportunity to write about my experiences and thoughts while doing knowledge sharing activities as a side job for the past four years.

Anyone can read it without having to join the cafe, so if there's anyone who's thinking about participating in knowledge sharing activities in the future, I recommend that you use it as a reference.
