Deploying Backend Platforms on Kubernetes and OpenShift
Best practices for containerizing Python backend applications, managing configuration secrets, and setting up health probes for resilient cloud deployment.
Deploying microservices to container platforms like Kubernetes or Red Hat OpenShift requires careful attention to container build steps, health probe endpoints, and non-root execution rules.

1. Multi-Stage Docker Builds
Keep deployment image sizes minimal and secure by separating build toolchains from execution runtimes.

2. Health & Readiness Probes
Configuring proper `livenessProbe` and `readinessProbe` manifests ensures Kubernetes zero-downtime rolling updates:
- **Liveness Probe (`/health`)**: Checks if the container process is responsive. - **Readiness Probe (`/api/v1/health/ready`)**: Checks if downstream dependencies (PostgreSQL, Redis) are healthy before routing traffic.
