我有一個symfony2應用程序。我們之前已經爲開發建立了一個docker-compose棧,這就是爲什麼我們希望它的所有配置都是通過環境變量而不是parameters.yml進行設置的。如何修復ParameterCircularReferenceException?
因此,我取代了我parameters.yml的內容來源:
parameters:
locale: 'en'
secret: 'SOME_SECURITY_TOKEN'
...
到:
parameters:
locale: '%locale%'
secret: '%secret%'
...
我docker-compose.yml
文件包含:
my_app:
hostname: my-app
build: .
dockerfile: Dockerfile.dev
ports:
- "9080:80"
- "9043:433"
environment:
LOCALE: en
SECRET: SOME_SECURITY_TOKEN
...
然而,重建我的容器後,我獲得例外:
ParameterCircularReferenceException in ParameterBag.php line 209: Circular reference detected for parameter "secret" ("secret" > "secret").

2. at ParameterBag->resolveString('%secret%', array('secret' => true)) in ParameterBag.php line 185

然而,在我的容器我也看到了ENV變量:
le-container:/var/www/my-app# env
SECRET=SOME_SECURITY_TOKEN
LOCALE=en
什麼我做錯了,如何解決呢?
你的描述是什麼;-)的parameterbag級解析「參數值譜寫」並在它們的parameters.yml中查找,所以這是無止境的 –
@johnSmith看起來你已經在symfony2源代碼中找到了負責任的部分。你能否添加一個鏈接到相關部分?我想我會在他們的github上公開一個關於它的問題。 – k0pernikus
我認爲你誤解了,你的實際問題是參數名稱是相等的,所以類解析引用並再次在parameters.yml中找到引用,等等,但它是一個內置功能使用外部參數;-) –
