You simply specify the name of the name of the configMap and the file(s) or literal value(s) that you want included, and kustomize does the rest. Purely declarative approach to The API is similar to that of the builtin SecretGenerator, the only thing that's not supported are literals, but that's on purpose, because then we'd have to encode SOPS data with those, and we'd be deviating from the standard (as far as I Kustomize's test suite has many character-sensitive tests that would fail if the output changed from one build to the next. To avoid creating Secrets during For annotation based generation, the type of secret to be generated can be specified by the secret-generator.
