Le conteneur Docker se bloque au démarrage: java.net.NoRouteToHostException: Aucune route vers l'hôte

Question

Ces derniers jours, mon conteneur Docker (SonarQube) se bloque quelques secondes après avoir été démarré. Il semble qu'il ne peut plus se connecter au conteneur de la base de données. Comment puis-je les reconnecter ensemble?

conteneur MySQL commande run:

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

création d'utilisateur MySQL:

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; 

conteneur sonarqube commande run:

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 

Et voici les journaux Docker:

Même si je crée des conteneurs entiers à partir de zéro, le conteneur SonarQube se bloque.

Une de mes hypothèses est que mes SERVER_IP_ADDRESS et mes BRIDGE_IP_ADDRESSES ne sont pas contournés par proxy, mais je n'ai pas réussi en modifiant la variable d'environnement $ no_proxy.

Answer 1

J'ai finalement utilisé une base de données PostgreSQL au lieu d'une base de données MySQL et cela a fonctionné.

J'ai utilisé docker-compose avec un fichier yml qui décrit les deux services dans le même réseau: la base de données et Sonarqube.

---

Pour d'autres conteneurs qui rencontrent le problème « Pas de route pour accueillir », je devais utiliser le DOCKER_BRIDGE_IP_ADDRESS dans les paramètres de l'application au lieu de la adresse_serveur_IP (qui n'a pas été reconnu à l'intérieur des conteneurs).

Answer 2

Pour la propriété d'environnement SONARQUBE_JDBC_URL, au lieu de SERVER_IP_ADDRESS, utilisez le nom d'alias du conteneur lié (dans votre cas, il s'agit de mysql). Ainsi, votre commande serait

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" \
