This document outlines the comprehensive Kubernetes deployment strategy for your microservices, encompassing core deployment manifests, Helm charts for packaging, service mesh configurations for advanced traffic management, sophisticated scaling policies, and robust monitoring configurations. This deliverable provides a detailed, actionable framework for deploying and managing your applications on Kubernetes.
This section details the generated Kubernetes deployment strategy, providing a structured approach to deploy, manage, scale, and observe your microservices within a Kubernetes environment. Each component is designed to ensure high availability, resilience, and operational efficiency.
These manifests form the foundation of your microservice deployments, defining how your application pods are created, exposed, and configured within the cluster.
Deployment)The Deployment resource manages a set of identical pods, ensuring they are running and available. It handles rolling updates, rollbacks, and self-healing.
Key Considerations:
Example Template (deployment.yaml):
apiVersion: apps/v1
kind: Deployment
metadata:
name: your-microservice-name
labels:
app: your-microservice-name
environment: production # or staging, development
spec:
replicas: 3 # Recommended starting point, adjust based on load
selector:
matchLabels:
app: your-microservice-name
template:
metadata:
labels:
app: your-microservice-name
version: v1.0.0 # Label for versioning, useful with service mesh
spec:
serviceAccountName: your-microservice-sa # If specific permissions are needed
containers:
- name: your-microservice-name-container
image: your-image-repo/your-microservice-name:v1.0.0 # Replace with actual image
ports:
- containerPort: 8080 # Replace with your application's port
name: http
envFrom: # Recommended for config management
- configMapRef:
name: your-microservice-config
- secretRef:
name: your-microservice-secrets
resources:
requests: # Minimum resources required for scheduling
cpu: 200m # 20% of a CPU core
memory: 256Mi # 256 Megabytes
limits: # Maximum resources a container can consume
cpu: 500m
memory: 512Mi
livenessProbe: # Checks if the container is running and healthy
httpGet:
path: /health # Replace with your health check endpoint
port: http
initialDelaySeconds: 15 # Wait before first probe
periodSeconds: 10 # Check every 10 seconds
timeoutSeconds: 5
failureThreshold: 3
readinessProbe: # Checks if the container is ready to serve traffic
httpGet:
path: /ready # Replace with your readiness check endpoint
port: http
initialDelaySeconds: 5
periodSeconds: 5
timeoutSeconds: 3
failureThreshold: 2
volumeMounts:
# Example for mounting a configuration file from a ConfigMap
# - name: config-volume
# mountPath: /app/config
# readOnly: true
# volumes:
# - name: config-volume
# configMap:
# name: your-microservice-config
Service)A Service defines a logical set of Pods and a policy by which to access them. This provides a stable network endpoint for your microservice, abstracting away the dynamic nature of pod IPs.
Key Considerations:
selector: Matches pods by labels (e.g., app: your-microservice-name).type: * ClusterIP (default): Internal only, accessible within the cluster.
* NodePort: Exposes the service on a static port on each node.
* LoadBalancer: Provisions an external cloud load balancer (if supported by your cloud provider).
* ExternalName: Maps the service to an external DNS name.
Example Template (service.yaml):
apiVersion: v1
kind: Service
metadata:
name: your-microservice-name
labels:
app: your-microservice-name
spec:
selector:
app: your-microservice-name # Matches the labels on your Deployment's pods
ports:
- protocol: TCP
port: 80 # Service port (internal to cluster)
targetPort: http # Matches the 'name' of the containerPort in Deployment
name: http
type: ClusterIP # Use LoadBalancer for external access, or NodePort
Ingress)An Ingress manages external access to the services in a cluster, typically HTTP/S. It provides load balancing, SSL termination, and name-based virtual hosting. Requires an Ingress Controller (e.g., NGINX Ingress, AWS ALB Ingress).
Key Considerations:
host: The domain name for external access.paths: URL paths to route to specific services.Example Template (ingress.yaml):
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: your-microservice-name-ingress
annotations:
# Example for NGINX Ingress Controller
nginx.ingress.kubernetes.io/rewrite-target: /$1
kubernetes.io/ingress.class: nginx
# Example for cert-manager for automatic TLS
cert-manager.io/cluster-issuer: letsencrypt-prod # Or your preferred issuer
spec:
tls: # Recommended for production environments
- hosts:
- api.your-domain.com # Replace with your actual domain
secretName: your-microservice-tls # Secret to store the TLS certificate
rules:
- host: api.your-domain.com # Replace with your actual domain
http:
paths:
- path: /your-microservice-name(/|$)(.*) # Example path prefix
pathType: Prefix
backend:
service:
name: your-microservice-name # Refers to your Service name
port:
name: http # Refers to the named port in your Service
ConfigMap & Secret)ConfigMap stores non-confidential configuration data, while Secret stores sensitive data like API keys or database credentials. Both can be injected into pods as environment variables or mounted as files.
Example Template (configmap.yaml):
apiVersion: v1
kind: ConfigMap
metadata:
name: your-microservice-config
data:
LOG_LEVEL: INFO
DATABASE_HOST: postgres-service.database-namespace.svc.cluster.local
API_BASE_URL: http://another-microservice.your-namespace.svc.cluster.local:8080
# Add other non-sensitive configurations here
Example Template (secret.yaml):
apiVersion: v1
kind: Secret
metadata:
name: your-microservice-secrets
type: Opaque # Or kubernetes.io/dockerconfigjson, etc.
stringData: # Use stringData for plain text, K8s will base64 encode it
DATABASE_PASSWORD: supersecurepassword123
API_KEY: your-api-key-12345
# Add other sensitive configurations here
Best Practices for Manifests:
