Kubernetes ConfigMap Generator
Generate a Kubernetes ConfigMap manifest from key-value configuration data.
Add your configuration key-value pairs - this tool generates a valid ConfigMap manifest.
ConfigMaps are for non-sensitive configuration only - for passwords, tokens, or keys, use the Kubernetes Secret YAML Generator instead.
What Is a Kubernetes ConfigMap?
A ConfigMap stores non-sensitive configuration data as key-value pairs, which Pods can consume as environment variables, command-line arguments, or files mounted from a volume - keeping configuration separate from container images.
Why Use This Tool?
ConfigMap YAML has a specific data block format, and multi-line values (like a full config file's contents) need correct YAML block-scalar syntax to avoid corrupting the content. This tool handles both cleanly.
How to Use It
- Add one or more key-value configuration pairs.
- Enter a ConfigMap name and optional namespace.
- Copy the generated YAML and apply it, then reference it from a Pod's
envFromorvolumes.
Limitations
ConfigMaps are stored unencrypted and are not intended for secrets - values like passwords or API tokens belong in a Kubernetes Secret instead, even though both use a similar YAML structure.
