Kubernetes Insights Report - December 2025
Published in January 2026
TL;DR: This report examines the December 2025 content performance across the LearnKube network (LearnKube, Kube Architect, Kubesploit, Kube Builders, Kube Events, Kube Careers, KubeFM, and KubeToday), comparing key metrics with November 2025 to identify trends and optimization opportunities.
During December 2025, we published 2,344 content pieces across multiple platforms, generating over 3.13 million social media impressions.
Articulating our publishing strategy further, we've published twice as many content pieces for December (from November's 1,144 pieces), a result of which is a staggering total of 3.13 million impressions across all of our brands for December 2025 (a 102% increase month-on-month).
Executive Summary
Key Performance Dashboard - December vs November 2025
December 2025 has proven to be the best month for the Learnkube network since its inception in 2018. The total impressions grew by a whopping 102% month-on-month, which is a feat considering November's large base of 1.5 million plus impressions.
Even with a 2X increase in total impressions, the efficiency has stayed in the year-topping range
November 2025 has been the most efficient month for 2025, with 1352.30 impressions per content piece.
What's even more interesting is how, despite bringing in more than twice the impressions for December 2025, we've managed to achieve an efficiency of 1339.47 impressions for the month, just 0.9% off the November peak numbers!
The metrics for the last two months of 2025 have set a new benchmark for the network, a benchmark we aim to surpass in 2026.
Top 3 Data-Driven Insights
- Configuration management content achieves highest ever efficiency - 6,892 impressions per post.
- Security attains highest ever CTR for a high volume topic - 3.93% CTR in December. Was 3.89% (was the highest in November as well).
- Walkthroughs drive most engagement - 45% contribution to the highest CTR content + Average CTR of 3.40%.
Volume & Reach Analysis
Let's examine the content performance in relation to popular social media platforms.
41.6% of all our posts were published on Twitter (given the short-form nature of the platform), while 30.5% were on Telegram, and 23.4% were on LinkedIn.
While YouTube accounted for 4.2%, Spotify made up just 0.2% of the total posts.
Next, let's review performance metrics for each platform to see how their results differ.
While LinkedIn has led the total impressions for most of 2025, for December, it has peaked in terms of efficiency with an impressive 2,582 impressions per post.
What's interesting to notice is how this efficiency was achieved despite the 70% increase in volume (for the platform).
Twitter has achieved its highest ever impressions for 2025: 1.4 million.
Although a part of the reason for this is how Twitter now records impressions, compared to the numbers in November (when the update was pushed), it's a staggering 102% rise.
How our preference changed for LinkedIn as a platform
As we learned of LinkedIn's high efficiency, we slowly altered our publishing strategy, prioritising the professional network more.
As can be seen in the graph, LinkedIn made up for 15-19% of our total posts in the first half of 2025, a metric which now averages 23-27% in the latter half of 2025.
What's even more interesting to see is how the total impressions for the platform have gradually increased with each month in 2025, eventually peaking in December with almost twice as many impressions as the yearly average.
LinkedIn is the most efficient platform for cloud-native content, so if you are a marketer/content creator in the cloud-native space, prioritize the platform in your content publishing strategy.
Content Category Deep Dive
December has been a benchmark-setting month for topic categories as well. Let's dive deeper.

| Certifications | 4 | 1,972 | 493 | 7.40% |
| Edge & IoT | 7 | 2,724 | 389 | 1.84% |
The key takeaways from the analysis are:
- December marks the first time a topic category has crossed an efficiency figure of 6,000 impressions per piece, with Configuration management achieving an efficiency of 6,892 for the month. A whopping 179% increase month-on-month, an impressive feat considering the publishing volume for December is 2X that of November.
- Next in the efficiency order are
- Resource management, which has been at the top four in almost all the months of 2025, and
- Networking, which has never been in the top three for 2025.
- Volume-wise, the hierarchy is headed by Infrastructure (a usual in terms of volume for 2025) with 436,119 impressions, followed by Configuration Management (372,162) > Resource Optimization (293,304) > Platform Engineering (256,139).
- What's interesting to see is Security topics had the highest CTR for the second month running (3.93%), while the average CTR for all topics (excluding Certifications and Edge & IoT) stands at an impressive 3.32% (ditto as of November 2025).
CTR Performance Comparison (December vs November 2025)
A notable change between the two months warrants further breakdown.
As the volume is low to begin with, we'll ignore statistics for Edge & IoT, as well as certification-based content.
Here are the key changes worth noting:
- The month-on-month gainers are Data on Kubernetes (risen by 1.46pp), Platform Engineering (0.43pp increase), and Configuration management (higher by 0.34pp).
- While the topics losing the most CTR month-on-month are: Infrastructure (lower by 0.92pp), Networking (down by 0.66pp), and November's hottest topic - Observability, which fell by 0.40pp.
- The average CTR for the two months differed by just 0.02 percentage points, which is admirable since December recorded twice as many impressions as November.
Account Performance Analysis
December appears to be consistent with the account trends established in the previous reports.
The following are the key trends reflected in the previous two months as well:
- Architectural content makes up for almost 33% of the total impressions recorded across all of our brands.
- Educational / News / Architectural content outperforms Event / Jobs / Podcast-based content, highlighting how the audience is mainly drawn towards learning.
Top Content Performance Analysis
Highest Volume Content (>15k impressions)
Interestingly, the top-performing content (volume-wise) was a tutorial/walkthrough of how to achieve horizontal scaling with Gunicorn and Kubernetes HPA with almost 50,000 impressions.
Next was a tool overview for Freelens, a GUI, with 40,017 impressions, followed by a monitoring guide using Prometheus and Grafana (29,022), Kubeterm (26,491 impressions), and OpenBao (25,312 impressions), both tool overviews, where the first is a graphical management tool, while the latter is a secrets storage solution.
For the second month running, the top four content pieces were a mix of walkthroughs and tool overviews, a change from the average where tool overviews dominated most of the top-performing content in 2025.
Highest CTR Content ( >6% and above 5,000 impressions )

|---|---|---|---|
| Building Kubernetes (a lite version) from scratch in Go | 17.51% | 7,649 | 1,339 |

It becomes fascinating when we categorize the highest CTR content by category and subcategories.
The key takeaways here are:
- Walkthroughs are in high demand, which signals that the audience looks forward to a hand-holding approach towards tutorials.
- 33% of the best CTR content is tool overviews, while 22% are opinion pieces.
Key Trends and Insights
December 2025 confirms Configuration management content as top tier.
While Configuration management has been one of the best-performing topic categories throughout the year, December marks the point for dominance of the topic.
Most efficient topic ever since the network's inception, with a good base of 372K plus impressions, and good CTR.
Networking may be the next big trend heading into 2026
Networking has never been in the top trending topics for 2025, yet, for December, it has shown great content efficiency.
This may turn out to be a pivot point for the topic heading into 2026.
LinkedIn is the most efficient platform for cloud-native content. Period.
While we've experimented with different publishing strategies across all platforms, LinkedIn has emerged as the most efficient one throughout 2025. Even LinkedIn video has been accepted by the cloud-native community with open arms.
If you are a marketer/content-creator in the cloud-native space, prioritize LinkedIn in your publishing strategy.
The cloud-native community clicks on tutorials where there's hand-holding and a personal touch.
While the whole of tech community seeks knowledge, it draws clicks when the title is intriguing, there's a personal touch to the narration, and when it isn't a simple compilation of steps.
Your tutorials will receive a lot more clicks when there's an interesting title and more hand-holding involved (and fewer syntax steps).
