我在docker中运行spring boot应用程序时遇到了一些问题。
堆栈:maven 3+,spring boot(jpa / rest / jetty) - mysql - 在docker中部署所以,我已经在我的pom文件中了

环境: Ubuntu 16.04 x64 问题: 本地:我尝试在终端
中使用follow命令运行我的应用程序user$ java -Xmx768m -jar /mnf-backend.jar --spring.datasource.url=jdbc:mysql://$MYSQL_PORT_3306_TCP_ADDR/app_1?autoReconnect=true&useSSL=false
user$ #<--- LOOK AT THIS jvm has return of control with 1 status (or same status but not negative)
:: Spring Boot :: (v1.4.0.M3) # <--- spring boot starts by itself. HOW????
我能忍受它并不好。但不是码头工人。 当上面的命令将在docker中运行,然后docker stop container(因为 - &gt; app exit,状态为1)
ENTRYPOINT ["java", "-Xmx768m", "-jar", "/mnf-backend.jar", "--spring.datasource.url=jdbc:mysql://$MYSQL_PORT_3306_TCP_ADDR/app_1?autoReconnect=true&useSSL=false"]
Docker将启动容器1秒并立即停止容器,因为java返回控制。 我寻找方法,允许我配置spring应用程序的可预测行为或任何想法如何改进我的docker指令。 我的dockerfile内容:
FROM frolvlad/alpine-oraclejdk8:slim
ENV MNFB_ENV production
ENV SERVER_PORT 9000
ADD ./builds/mnf-latest.jar mnf-backend.jar
EXPOSE 9000
ENTRYPOINT ["java", "-Xmx768m", "-jar", "/mnf-backend.jar", "--spring.datasource.url=jdbc:mysql://$MYSQL_PORT_3306_TCP_ADDR/minifinance?autoReconnect=true&useSSL=false"]
例如:当我启动nodejs app控件时,在应用程序未完成之前不会返回
user$ node ./server.js
[...here program output and stdout strings]
[... it may be stopped by ctrl+c for example]
答案 0 :(得分:8)
我认为问题在于命令行中的&符号(&amp;):
--spring.datasource.url=jdbc:mysql://$MYSQL_PORT_3306_TCP_ADDR/app_1?autoReconnect=true&useSSL=false"]
试着逃避它:
--spring.datasource.url=jdbc:mysql://$MYSQL_PORT_3306_TCP_ADDR/app_1?autoReconnect=true\&useSSL=false"]
&符表示在后台启动进程的shell。这正是您本地计算机上发生的事情。如果你启动你的jar,那么这个过程应该从前台开始......并且提示不应该直接返回。

为了保持简单和干净,我们在database.properties
中添加了数据库属性spring.data.mongodb.database=abc-auth
spring.data.mongodb.host=192.168.2.2
spring.data.mongodb.port=27017
spring.data.mongodb.password=abc234quth
spring.data.mongodb.username=abc-auth
我们在运行Docker时推送此文件,因此只有数据库属性才会被现有的application.properties覆盖
ENTRYPOINT ["java","-jar","/home/docker/service/abc.jar","--spring.config.location=application.properties"]
