I'm trying to deploy my Spring Boot application in Minikube using Helm charts. I have a configuration class where I map all the @value variables. If keep my map value in application.yaml or applicationConfig.yaml file then
@Value("#{${user.apiKey}}")
private Map<String, String> userApiKeyMap;
works fine.
But if I want to pass this map from values.yaml then it's not working. Below are the things I tried and errors I got.
Try 1:
user:
apiKey:
key1: "value1"
key2: "value2"
org.springframework.expression.spel.SpelParseException: Expression [map[key1:value1 key2:value2]] @6: EL1043E: Unexpected token. Expected 'rsquare(])' but was 'colon(:)'
Try 2:
user:
apiKey: |-
key1: "value1"
key2: "value2"
Error: UPGRADE FAILED: YAML parse error on user-service/templates/applicationConfig.yaml: error converting YAML to JSON: yaml: line 29: did not find expected key
Try 3:
user:
apiKey: { key1: "value1",
key2: "value2" }
org.springframework.expression.spel.SpelParseException: Expression [map[key1:value1 key2:value2]] @6: EL1043E: Unexpected token. Expected 'rsquare(])' but was 'colon(:)'
Try 4:
user:
apiKey: '{ "key1": "value1",
"key2": "value2" }'
nested exception is java.lang.IllegalArgumentException: Could not resolve placeholkey2r 'user.apiKey' in value "#{${user.apiKey}}"
Try 5:
user:
apiKey:
- "key1": "value1"
- "key2": "value2"
