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:

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
