ConfigMap Reference Guidelines
1. Injection Strategies
ConfigMaps can inject data into container environments via `envFrom`, individual environment variables, or as mounted configuration volumes.
2. Naming Conventions
Keys must consist of alphanumeric characters, hyphens, underscores, or dots to ensure compatibility with environment variable naming specs.
Frequently Asked Questions (FAQ)
No. ConfigMaps store plain text configuration data. For confidential information such as passwords or tokens, use Kubernetes Secrets instead.
Save the copied YAML manifest to a file (e.g.,
configmap.yaml) and run kubectl apply -f configmap.yaml in your terminal.
When mounted as volumes, Kubernetes automatically updates files, though application processes typically require a signal or restart to re-read configurations. Environment variables do not update dynamically.
