为什么 Keycloak 不断重新部署同一个 .jar 文件？

编程问答 2022-05-17

问题描述

我有一个自定义的 SPI javascript 提供程序，打包在 .jar 文件中，如官方 Keycloak 文档中所述。 对于本地开发，我通过 docker-compose 文件使用 jboss/keycloak docker 图像，并将卷映射到 standalone/deployments 文件夹集。 包已部署并运行正常，但 Keycloak 会每 5 秒重新部署一次相同的文件：

11:43:58,304 INFO  [org.keycloak.subsystem.server.extension.KeycloakProviderDeploymentProcessor] (MSC service thread 1-8) deploying Keycloak provider: custom-auth-provider.jar

这是一种理想的行为，还是我能以某种方式阻止它？

解决方法

显然，docker-compose volumes 是问题所在。随着 Wildfly AS 自动部署 .jar 包，文件的属性发生了变化，这导致 Wildfly 将其作为更新文件使用。 将特定卷映射更改为“绑定”类型

volumes:
      - type: bind  # bind mount type prevents file changes
        source: ./standalone/deployments/
        target: /opt/jboss/keycloak/standalone/deployments

成功了
