Microservices - Configuration and Secrets Management

A microservice uses environment variables for database connection strings. During scaling, some instances fail to connect. What is the best way to ensure consistent environment configuration across all instances?

AIgnore environment variables and use default local settings

BManually set environment variables on each instance

CEmbed connection strings in the microservice code

DUse a centralized configuration service that injects environment variables at startup

Step-by-Step Solution

Solution:

Step 1: Identify scaling challenges
Manually setting env vars on many instances risks inconsistency and errors.
Step 2: Choose centralized config
A centralized config service ensures all instances get consistent env vars automatically.
Final Answer:
Use a centralized configuration service that injects environment variables at startup -> Option D
Quick Check:
Central config service ensures consistency = A [OK]

Quick Trick: Central config services keep env vars consistent at scale [OK]

Common Mistakes:

Manually setting env vars on many instances
Hardcoding connection strings
Ignoring environment configs
