操作系统-Windows 7
Docker版本:Docker版本18.03.0-CE,版本0520E24302
springboot版本:1.5.3.发布
我从https://github.com/techprimers/docker-mysql--boot-example中获取了代码库(这是macOS中的工作示例代码)
我的应用程序.属性如下所示
# 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映像(https://Hub.Docker.com/_/MySQL/)命令运行MySQL容器
docker运行--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映像。从Dockerfile目录中-
docker建造。-t用户-MySQL
我看到docker映像创建的用户-MySQL
docker运行-p 8086:8086--命名用户-mysql--链接mysql-独立:mysql-d用户-mysql
我看到应用程序在名为users-mysql的docker容器中运行
无法访问此站点本地主机拒绝连接。
我做错什么了吗?
基于一些评论,我想添加应用程序启动日志。

答案很简单。虽然所有的事情都发生在windows上,但它的底层操作系统是Linux,所以我们不得不用VM的Linux机器的ip地址替换localhost
因此,我没有点击http://localhost:8086/all/,而是点击http://192.168.99.100:8086/all/
