Docker容器在启动时崩溃：java.net.NoRouteToHostException：没有到主机

标签： mysql docker crash sonarqube docker-container

最近几天，我的Docker容器（SonarQube）在启动后几秒钟就崩溃了。它似乎无法再连接数据库容器。我怎样才能将它们重新连接在一起？

MySQL容器run命令：

docker run -d --name mysql-sonarqube-container \
-e MYSQL_ROOT_PASSWORD=root \
-p 3307:3306 \
-v /etc/mysql:/etc/mysql/conf.d \
mysql:latest

MySQL用户创建：

use sonar;
CREATE USER 'sonar'@'DOCKER_BRIDGE_IP_ADDRESS' IDENTIFIED BY 'sonar';
GRANT ALL PRIVILEGES ON *.* TO 'sonar'@'DOCKER_BRIDGE_IP_ADDRESS' WITH GRANT OPTION;

SonarQube容器run命令：

docker run -d --name sonarqube-container \
--link mysql-sonarqube-container:mysql \
-p 9000:9000 -p 9092:9092 \
-e SONARQUBE_JDBC_USERNAME=sonar \
-e SONARQUBE_JDBC_PASSWORD=sonar \
-e SONARQUBE_JDBC_URL="jdbc:mysql://SERVER_IP_ADDRESS:3307/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true" \
-e SONARQUBE_HOST_URL="http://DOCKER_BRIDGE_IP_ADDRESS:9000" \
sonarqube:latest

以下是Docker日志：

即使我从头开始创建全新的容器，SonarQube容器也会崩溃。

我的假设是我的SERVER_IP_ADDRESS和我的BRIDGE_IP_ADDRESSES没有被代理绕过，但是我没有通过修改$ no_proxy环境变量来成功。

2 个答案:

答案 0 :(得分：0)

对于env属性SONARQUBE_JDBC_URL，而不是SERVER_IP_ADDRESS，使用链接容器的别名（在您的情况下，它是mysql）。所以，你的命令是

docker run -d --name sonarqube-container \
--link mysql-sonarqube-container:mysql \
-p 9000:9000 -p 9092:9092 \
-e SONARQUBE_JDBC_USERNAME=sonar \
-e SONARQUBE_JDBC_PASSWORD=sonar \
-e SONARQUBE_JDBC_URL="jdbc:mysql://mysql:3307/sonar?useUnicode=true&characterEncoding=utf8&rewriteBatchedStatements=true" \
-e SONARQUBE_HOST_URL="http://DOCKER_BRIDGE_IP_ADDRESS:9000" \
sonarqube:latest

答案 1 :(得分：0)

我最终使用了PostgreSQL数据库而不是MySQL数据库，并且它有效。

我使用docker-compose和yml文件来描述同一网络中的两种服务：数据库和Sonarqube。

对于遇到“无路由到主机”问题的其他容器，我不得不在应用程序设置中使用DOCKER_BRIDGE_IP_ADDRESS而不是SERVER_IP_ADDRESS（无法从容器内部识别）。
