Overview
Deployment is the crucial final step in the development process. This guide walks through strategies, environments, and automation techniques.
Deployment Strategies
GitOps
Use declarative APIs and Git repositories as the source of truth for infrastructure and application configurations.
# Example Argo CD command
git commit -am "Deploy update"
git push origin main
Blue/Green
Deploy new versions to parallel production environments and swap at the DNS level.
kubectl apply -f blue-deployment.yaml
kubectl annotate deployments/app-color "color=blue"
Canary
Roll out changes incrementally through routing percentages.
istioctl route add-route mymesh
--host=www.prod.com
--route=canary 20%
Best Practices
Infrastructure as Code
Store deployment infrastructure in version-controlled repositories for traceability and collaboration.
# example terraform.tf
provider "aws" {
region = "us-west-2"
}
Automated Rollbacks
Define rollback strategies in CI/CD tooling for automatic remediation.
