Question

我正在尝试使用ubuntu上的docker-compose文件将jasper-reports服务器与MySQL数据库连接。这里我们为jasper服务器和MySQL编写了单独的docker文件。在执行docker-compose时，我们得到了类似port 3306 is not reachable at host db的错误。这是我的MySQL容器的服务名称。

以下是我的docker-compose.yaml配置文件，MySQL的docker文件和default_master.properties。

FROM ubuntu:16.04
RUN apt-get update && \
    DEBIAN_FRONTEND=noninteractive apt-get install -y mysql-server && \
    sed -i "s/127.0.0.1/0.0.0.0/g" /etc/mysql/mysql.conf.d/mysqld.cnf && \
    mkdir -p /var/lib/mysql && \
    mkdir -p /var/run/mysqld && \
    mkdir -p /var/log/mysql && \
    chown -R mysql:mysql /var/lib/mysql && \
    chown -R mysql:mysql /var/run/mysqld && \
    chown -R mysql:mysql /var/log/mysql
VOLUME ["/var/lib/mysql"]
EXPOSE 3306
CMD ["mysqld_safe"]

default_master.properties文件

# Application Server Settings
appServerType=tomcat
# Tomcat app server root dir
appServerDir=/usr/local/tomcat
# database type
dbType=mysql
# database location and connection settings
dbHost=db
dbUsername=root
dbPassword=mysql
# additional database parameters
# (uncomment these if you want non-default settings)
dbPort=3306
# JasperServer db name, sample db names
js.dbName=jasperserverdb

docker-compose.yaml

version: '3.3'
services:
  db:
    build:
      context: .
      dockerfile: mysql-docker
    image: 'mysql:latest'

    environment:
      - MYSQL_ROOT_PASSWORD=mysql
    ports:

    volumes:

    ports:

    depends_on:

    driver: local

您可以看到以下快照中遇到的确切错误。

有人可以建议我解决此问题吗？

错误：主机数据库上无法访问端口3306
