spring-boot无法在docker中启动

Question

我在docker中运行spring boot应用程序时遇到了一些问题.

stack: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

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.0.M3</version>

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 - > 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"]

docker日志的容器

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]

Answer 1

我认为问题是命令行中的&符号(&):

--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"]

&符号表示在后台启动进程的shell.这正是本地机器上发生的事情.如果你启动你的jar,进程应该从前台开始......并且提示不应该直接返回.
