Helm: Reading and Debugging Templates

The cert-manager controller deployment isn't starting. The pod is crash-looping, the logs mention an unrecognized flag, and the chart installed without errors. You run helm status cert-manager — deployed. Everything looks fine until it isn't.

The problem is that Helm separates rendering from validation. A chart can install successfully, produce syntactically valid YAML, and still deploy something that behaves differently than you expected — because the template rendered differently than you thought based on your values. Reading and debugging templates is the skill that bridges that gap.
