在 Kubernetes 上启动 Quarkus 时出现 NumberFormatException

Question

我正在尝试将 Quarkus 应用程序部署到 Kubernetes 集群，但我得到了以下堆栈跟踪：

我使用默认的 dockerfile构建 Docker 镜像，我的 quarkus 相关依赖项如下：

exec java -Dquarkus.http.host=0.0.0.0 -Djava.util.logging.manager=org.jboss.logmanager.LogManager -XX:+ExitOnOutOfMemoryError -cp . -jar /deployments/quarkus-run.jar

我正在使用 Quarkus 1.13.3.Final，并且我已经为我的部署手动编写了一个 helm 图表。部署的 dockerfile 在我的机器上运行良好，并且 kubernetes 部署描述符中没有该 IP 地址。我认为该IP是集群的ClusterIP。

任何想法？谢谢

Answer 1

这是由于kubernetes 模仿范围内名称的docker 链接变量所致；Service当人们拥有通用命名的服务时，它会让人很痛苦，比如{ apiVersion: v1, kind: Service, metadata: { name: http }, ...它会在 Pod 中愉快地生成形式的环境变量HTTP_PORT=tcp://10.233.12.82:80，而诸如 Spring boot 或显然 Quarkus 之类的东西会强制环境变量进入配置覆盖，这可能会导致你想要的确切结果。正在经历

解决方案是 (a) 不要使用Services平淡的名称 (b) “屏蔽” Pod 的攻击性环境变量：

...
  containers:
  - ...
    env:
    - name: HTTP_PORT
    # it doesn't need a value:, it just needs the name to be specified
    # so it hides the injected version
    - ... any remaining env-vars you really want
