Сбой контейнера Docker при запуске: java.net.NoRouteToHostException: нет маршрута к хосту

Question

В последние дни мой контейнер Docker (SonarQube) вылетает через пару секунд после запуска. Кажется, что он больше не может подключить контейнер базы данных. Как я могу их повторно соединить?

MySQL контейнер run Команда:

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 Создание пользователя:

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 контейнер run Команда:

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 

А вот журналы Docker:

Даже если я создаю совершенно новые контейнеры с нуля, контейнер SonarQube сработает.

Моя гипотеза состоит в том, что мои SERVER_IP_ADDRESS и мои BRIDGE_IP_ADDRESSES не прокси-обойдены, но мне это не удалось, изменив переменную среды $ no_proxy.

Answer 1

Я, наконец, использовал базу данных PostgreSQL вместо базы данных MySQL, и она сработала.

Я использовал docker-compose с yml-файлом, который описывает обе службы в той же сети: базу данных и Sonarqube.

---

Для других контейнеров не встречая на «Нет пути для размещения» проблемы, я должен был использовать DOCKER_BRIDGE_IP_ADDRESS в настройках приложения вместо server_ip_address (который не был признан внутри контейнеров).

Answer 2

Для свойства env SONARQUBE_JDBC_URL вместо SERVER_IP_ADDRESS используйте псевдоним связанного контейнера (в вашем случае это mysql). Итак, ваша команда будет

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
