📖 Kubernetes Best Practices 📖

Hey there,

This week we discuss a couple of kubernetes best practices when it comes to the DaemonService Pattern and the Cron Job Pattern.

Go to blog

Daemon 1

Kubernetes Patterns - The DaemonService Pattern

What's inside:
  • What is a Daemon?
  • Do we need daemons in a Kubernetes cluster?
  • Why not just install the daemon on the node itself?
  • fluentd daemonset for log collection
  • How are DaemonSets different from ReplicaSets?
  • DaemonSet Pods access patterns.
Cron

Kubernetes Patterns - The Cron Jon Pattern

What's inside?
  • Scheduled jobs challenges.
  • My Crob job didn't start on time. what should I do?
  • My Cron job is taking too long. 
  • Does Cron job keep a history of the jobs that succeeded and failed?

This security issue makes the cluster’s Kubernetes API service vulnerable to an attack called “billion laughs”. The billion laughs attack is a type of denial-of-service (DoS) attack.

Choose the right container deployment and management system

Containers are only a piece of the puzzle -- they need orchestration to govern their deployment, availability and more. As enterprises map out a strategy for containerized applications, they now face dozens of options in the market. Generally, they all combine container software with some kind of orchestration, and the market has coalesced around a single technology option: Kubernetes.
