What we Learned from Reading 100+ Kubernetes Post-Mortems

Noaa Barki

Subtle YAML errors and missing memory limits are silently crashing your Kubernetes clusters. Uncover the leading root causes from 100+ post-mortems and automate infrastructure validation directly within CI workflows.

#1 about 7 min

Friction between developers and infrastructure teams

Developers prioritize feature delivery over infrastructure concepts like memory limits and resource configurations.

#2 about 2 min

Finding developers to champion infrastructure best practices

Identifying team members interested in both code and infrastructure helps bridge the knowledge gap.

#3 about 4 min

Common Kubernetes misconfigurations in production environments

Real-world examples show how missing concurrency policies or memory limits cause major performance outages.

#4 about 4 min

Rolling out policy enforcement to engineering teams slowly

Gradually introducing automated validations in local and CI environments prevents friction while protecting production.

#5 about 3 min

Three primary categories of Kubernetes infrastructure failures

Most production outages stem from YAML syntax errors, misunderstanding tool defaults, or misaligned internal practices.

#6 about 3 min

Validating resource syntax and schema without cluster access

Tools like yq and kubeconform ensure basic file format and schema correctness before deployment.

#7 about 4 min

Managing infrastructure policies and guiding developers effectively

Centralizing policy management and providing detailed remediation steps prevents developer frustration when builds fail.

#8 about 5 min

Automating customized policy enforcement with open source tools

Implementing tools like Datree or Conftest allows centralized policy control while enabling local developer testing.
