Docker 中的 SonarQube 无法解析本地主机

Question

我正在尝试使用 Alpine Linux Docker Image 在 Docker 中设置 SonarQube。但是，当运行图像时，SonarQube 似乎无法解析本地主机。以前有人遇到过这个问题吗？

非常感谢能帮助解决这个问题！

Answer 1

由于 InetAddress.html#getLocalHost 将 "retrieving the name of the host from the system"，请确保使用主机名启动容器。

docker run --add-host xxx --hostname yyy

见docker run Network Settings for --add-host and --hostname options

Answer 2

Alpine linux 中可能没有名称服务转换文件，例如 java java.net.InetAddress.getLocalHost 需要一个。

在 dockerfile 中添加这一行

RUN echo 'hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4' > /etc/nsswitch.conf

Answer 3

我运行在 k8s 上遇到了同样的问题，并通过提供环境变量强制数据库绑定到 127.0.0.1

来解决

kubectl run sonarqube --image=sonarqube --port=9092 --env="SONARQUBE_WEB_JVM_OPTS=-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Dh2.bindAddress=127.0.0.1"
