Question

OS- Windows 7

Docker版本：Docker版本18.03.0-ce，版本0520e24302

Springboot版本：1.5.3.RELEASE

我从https://github.com/TechPrimers/docker-mysql-spring-boot-example获取了代码库（这是MacOS中的示例代码。）

我的application.properties如下所示

# DataSource settings: set here your own configurations for the database
# connection. In this example we have "netgloo_blog" as database name and
# "root" as username and password.
spring.datasource.url = jdbc:mysql://mysql-standalone:3306/test
spring.datasource.username = testuser
spring.datasource.password = testuserpass

# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = create

# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager)

# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

server.port=8086

Dockerfile如下所示

FROM openjdk:8
ADD target/users-mysql.jar users-mysql.jar
EXPOSE 8086
ENTRYPOINT ["java", "-jar", "users-mysql.jar"]

使用Docker Hub发布的MySQL镜像（https://hub.docker.com/_/mysql/）运行mysql容器的命令

docker run --name mysql-standalone -e MYSQL_ROOT_PASSWORD = rootpass -e MYSQL_DATABASE = test -e MYSQL_USER = testuser -e MYSQL_PASSWORD = testuserpass -d mysql：5.6

我看到名为mysql-standalone的docker mysql容器。

使用Dockerfile创建Docker镜像。从Dockerfile目录 -

docker build。 -t users-mysql

我看到docker image创建了users-mysql

运行在＃3。

docker run -p 8086：8086 --name users-mysql --link mysql-standalone：mysql -d users-mysql

我看到应用程序在名为users-mysql的docker容器中运行

我尝试访问http://localhost:8086/all/ 我收到错误：

无法访问此网站 localhost拒绝连接。

我尝试检查应用程序的日志＆＃34; users-mysql＆＃34;和mysql容器＆＃34; mysql-standalone＆＃34; 但是，我没有看到任何错误或例外。

我做错了吗？

基于一些评论我想到了添加应用程序启动日志。

Answer 1

答案很简单。尽管一切都在Windows上进行，但是底层操作系统是Linux，因此我们必须用VM的linux机器的ip地址替换localhost

所以不要点击：http://localhost:8086/all/ 我必须点击：http://192.168.99.100:8086/all/
