java - docker 容器上的 Eureka : unknown host exception-6ren

java - docker 容器上的 Eureka : unknown host exception

转载作者：行者123 更新时间：2023-12-01 10:36:01

我试图通过 docker 容器上的 spring boot 启动 eureka 服务器并收到以下异常“unknownhostexception”。现在，在 eureka config.properties 文件中，我使用主机名作为 localhost，但异常(exception)情况是它以某种方式使用容器的主机名，而不是使用我在 eureka 属性文件中定义的主机名。此外，即使它使用容器定义的主机名，它也可以在容器上很好地解析到正确的 IP，并且在/etc/hosts 中有条目。

注意:

仅当我使用 oracle java 7/8 时，此情况才可重现，但在 openjdk 7 上工作正常。任何线索可能是什么问题。
尝试在 Eureka 属性中使用 127.0.0.1 代替 localhost，但没有成功。

Eureka 配置文件内容:

# Configure this Discovery Server
eureka:
  instance:
    hostname: localhost
  client:  # Not a client, don't register with yourself
    registerWithEureka: false
    fetchRegistry: false

server:
  port: 1111   # HTTP (Tomcat) port

最佳答案

通过在 docker 文件中添加以下解决方案解决了问题:

# Fix DNS resolution issues when nss is not installed
RUN echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' >> /etc/nsswitch.conf

# Set DNS cache to 10 seconds (Cache is permanent by default). Network hosts are volatile in Docker clusters.
RUN grep '^networkaddress.cache.ttl=' /opt/${JAVA_PACKAGE}/jre/lib/security/java.security || echo 'networkaddress.cache.ttl=10' >> /opt/${JAVA_PACKAGE}/jre/lib/security/java.security
