如何通過Docker Compose中的env vars為Jhipster Registry設置Spring Cloud Server的Git URI？

Question

在Jhipster Registry頁面上 ，提到我們可以通過以下參數為Spring Cloud Config設置Git存儲庫。

--spring.profiles.active=prod --spring.security.user.password=admin --jhipster.security.authentication.jwt.secret=secret-key --spring.cloud.config.server.composite=https://github.com/jhipster/jhipster-registry-sample-config --spring.cloud.config.server.composite[0].type=git --spring.cloud.config.server.composite[0].uri=https://github.com/jhipster/jhipster-registry-sample-config

但是我想通過docker-compose中的環境變量設置這些參數，我該如何實現呢？ 特別是這個：帶有方括號的spring.cloud.config.server.composite [0] .uri。

我嘗試了GaëlMarziou的答案中定義的拼寫，但是沒有用。 這是我使用的docker jhipster-registry.yml，它是通過jhipster docker-compose子生成器生成的，在其中添加了Spring Cloud Config

version: '2'
services:
    jhipster-registry:
        image: jhipster/jhipster-registry
        environment:
        - SPRING_PROFILES_ACTIVE=prod,git
        - SPRING_SECURITY_USER_PASSWORD=admin
        - JHIPSTER_REGISTRY_PASSWORD=admin
        - JHIPSTER_LOGGING_LOGSTASH_ENABLED=true
        - JHIPSTER_LOGGING_LOGSTASH_HOST=jhipster-logstash
        - JHIPSTER_METRICS_LOGS_ENABLED=true
        - JHIPSTER_METRICS_LOGS_REPORTFREQUENCY=60
        - SPRING_CLOUD_CONFIG_SERVER_COMPOSITE=https://github.com/anthonyrichir/demo-feign-config
        - SPRING_CLOUD_CONFIG_SERVER_COMPOSITE_0_TYPE=git
        - SPRING_CLOUD_CONFIG_SERVER_COMPOSITE_0_URI=https://github.com/anthonyrichir/demo-feign-config
        ports:
        - 8761:8761

使用此配置，注冊表會顯示：

Failed to bind properties under 'spring.cloud.config.server.composite' to java.util.List<java.util.Map<java.lang.String, java.lang.Object>>:

    Reason: No converter found capable of converting from type [java.lang.String] to type [java.util.List<java.util.Map<java.lang.String, java.lang.Object>>]

我也嘗試了這種配置：

version: '2'
services:
    jhipster-registry:
        image: jhipster/jhipster-registry
        environment:
        - SPRING_PROFILES_ACTIVE=prod,git
        - SPRING_SECURITY_USER_PASSWORD=admin
        - JHIPSTER_REGISTRY_PASSWORD=admin
        - JHIPSTER_LOGGING_LOGSTASH_ENABLED=true
        - JHIPSTER_LOGGING_LOGSTASH_HOST=jhipster-logstash
        - JHIPSTER_METRICS_LOGS_ENABLED=true
        - JHIPSTER_METRICS_LOGS_REPORTFREQUENCY=60
        - SPRING_CLOUD_CONFIG_SERVER_COMPOSITE_0_TYPE=git
        - SPRING_CLOUD_CONFIG_SERVER_COMPOSITE_0_URI=https://github.com/anthonyrichir/demo-feign-config
        ports:
        - 8761:8761

我收到此錯誤：

Answer 1

spring.cloud.config.server.composite[0].uri屬性應該映射到SPRING_CLOUD_CONFIG_SERVER_COMPOSITE_0_URI環境變量。
