Common Flairs

Who's Here

Platform engineers, SREs, DevOps practitioners, and developers working with Kubernetes. Highly technical. Many run production clusters. Open-source oriented and skeptical of vendor lock-in.

Common Mistakes on r/kubernetes

Avoid these pitfalls that get marketers banned or ignored.

Promoting closed-source or proprietary solutions

The Kubernetes community is deeply open-source oriented. Closed-source tools face immediate skepticism.

Instead

Lead with open-source components: "Core is open source, enterprise features are commercial." Offer meaningful free tiers.

Underestimating the technical depth required

This is one of the most technical communities on Reddit. Surface-level content gets dismissed.

Instead

Go deep: include YAML manifests, architecture diagrams, performance benchmarks, and failure scenarios.

Ignoring the CNCF ecosystem

Kubernetes users think in terms of the CNCF landscape. Tools that don't integrate with the ecosystem feel isolated.

Instead

Show ecosystem integration: "Works with Prometheus, OpenTelemetry, and Argo. Here's how it fits the CNCF stack."

Marketing managed Kubernetes without addressing complexity

Many users manage their own clusters. Managed solutions need to justify the cost and lock-in.

Instead

Be honest about trade-offs: "Managed K8s costs more but saves X hours/week. Here's our analysis."

Asking questions without sharing manifests

Kubernetes problems require configuration context. "It doesn't work" without manifests can't be debugged.

Instead

Always include relevant YAML, logs, and version information. Use code blocks for readability.

Post Formats That Work on r/kubernetes

These content formats consistently perform well in this community.

Open Source Announcement

Example Format

""Built [tool] to solve [K8s problem]. Open source, Apache 2.0. How it works, architecture, and roadmap. Looking for feedback.""

Why It Works

Open source first. Specific problem solved. Technical depth. Community feedback request.

Production War Story

Example Format

""How [outage/issue] took down our [scale] cluster. Timeline, root cause, and what we changed to prevent recurrence.""

Why It Works

Real production experience. Honest about failures. Actionable lessons for others.

Scale Architecture

Example Format

""Running [scale] pods across [clusters]. Our architecture, the problems we hit, and how we solved them.""

Why It Works

Concrete scale numbers. Real challenges. Battle-tested solutions rather than theory.

Frequently Asked Questions

Common questions about marketing on r/kubernetes

If it's open source or has a meaningful free tier, yes. The community is highly open-source oriented. Lead with technical value and be transparent about commercial aspects. Proprietary-only tools face significant resistance.
Production war stories, open-source tool announcements, and technical deep-dives at scale. The community values real operational experience over theoretical discussions.
Very technical. Include manifests, architecture diagrams, metrics, and specific version numbers. The audience operates production clusters and expects Kubernetes expertise.
Yes, for tools that genuinely improve Kubernetes operations. Success requires leading with open-source components, showing CNCF ecosystem integration, and providing substantial technical content.
Alpha/beta stage tools are welcome if you're seeking genuine feedback. Be clear about the maturity level. The community often helps shape early-stage projects.
Mixed. Many prefer self-managed for control and cost. Managed services need to clearly justify their value against DIY approaches. Cost comparisons and operational savings resonate.
