Kubernetes deployment best practices for Python applications

Nabarun Pal (~palnabarun)





Kubernetes is an open-source container orchestration platform designed for deploying workloads and massively scaling them. It gives you a lot of flexibility to manage and scale your workloads.

With great power comes great responsibility

However, as the above quote says, with that flexibility, there are a lot of ways someone can make mistakes while deploying their workloads.

Kubernetes provides you with a lot of tunable to make your applications:

  • configurable with proper configuration management
  • conform to resource limits like memory, CPU or GPU
  • running your application with different security contexts
  • making them resilient to infrastructure failures like server downtimes
  • distributed amongst the server pool
  • terminate gracefully on planned downtimes
  • respond to health checks related to readiness or liveness

Intended Audience

Developers or Platform Engineers who want to make their applications Kubernetes Native. All of the content in this talk is in public domain and can very well be researched by oneself. The motivation of this talk is to introduce to Kubernetes constructs serving as a starter to the world of making their services behave like a herd of destroyable workloads.
