Classify config by **volatility × scope** before deciding where it lives\n2. **Sensitivity overrides everything** — secrets go to Vault, no exceptions\n3. Four tiers: Vault → Spring Cloud Config → Kubernetes ConfigMap → `application.properties`\n4. The **ConfigMap lean rule**: if Kubernetes doesn't need to know about it directly, it doesn't belong in a ConfigMap\n5. The 4 GB etcd limit is a config hygiene symptom, not a storage problem\n\n## Built With\n\n- [RevealJS](https://revealjs.com) — presentation framework\n- [Spring brand fonts](https://fonts.google.com) — Work Sans + Open Sans\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdashaun%2Ftaming-configuration-with-spring-cloud-config","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdashaun%2Ftaming-configuration-with-spring-cloud-config","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdashaun%2Ftaming-configuration-with-spring-cloud-config/lists"}
