Env

Assume every key below has a prefix of workload.[workload-name].podSpec.containers.[container-name].

Key	Type	Required	Helm Template	Default	Description
env	dict	❌	❌	{}	Define env(s) for the container
env.[key]	string	✅	✅ (Only value)	""	Define the env key/value
env.[key].configMapKeyRef	dict	❌	❌	{}	Define variable from configMapKeyRef
env.[key].configMapKeyRef.name	string	✅	✅	""	Define the configMap name
env.[key].configMapKeyRef.key	string	✅	❌	""	Define the configMap key
env.[key].configMapKeyRef.expandObjectName	boolean	❌	❌	true	Whether to expand (adding the fullname as prefix) the configmap name
env.[key].secretKeyRef	dict	❌	❌	{}	Define secretKeyRef variable
env.[key].secretKeyRef.name	string	✅	✅	""	Define the secret name
env.[key].secretKeyRef.key	string	✅	❌	""	Define the secret key
env.[key].secretKeyRef.expandObjectName	boolean	❌	❌	true	Whether to expand (adding the fullname as prefix) the secret name
env.[key].fieldRef	dict	❌	❌	{}	Define fieldRef variable
env.[key].fieldRef.fieldPath	string	✅	❌	""	Define field path
env.[key].fieldRef.apiVersion	string	❌	❌	""	Define apiVersion

Environment variables defined in env will be scanned for duplicate keys between other secrets/configmaps/env/envList/fixedEnv and will throw an error if it finds any. secretKeyRef and configMapKeyRef with expandObjectName set to true will also be validated that the actual objects are defined and have the specified key. expandObjectName should only be set to false if you want to consume a secret/configmap created outside of this chart
