maven - jib-maven spring boot profile

问题描述

在我的springboot项目中，有三个配置文件

application.yml --> 用于本地开发
application-test.yml --> 运行在测试环境
application-prod.yml --> 运行在生产环境

pom.xml

...

<properties>
    <docker-repository>self-ip:port</docker-repository>
</properties>

...

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>

        <plugin>
            <groupId>com.google.cloud.tools</groupId>
            <artifactId>jib-maven-plugin</artifactId>
            <version>1.7.0</version>
            <configuration>
                <allowInsecureRegistries>true</allowInsecureRegistries>
                <from>
                    <image>openjdk:8-jre-alpine</image>
                </from>
                <to>
                    <image>${docker-repository}/${project.groupId}/${project.artifactId}</image>
                </to>
                <container>
                    <creationTime>USE_CURRENT_TIMESTAMP</creationTime>
                    <jvmFlags>
                        <jvmFlag>$JAVA_OPTS</jvmFlag>
                        <jvmFlag>-Dfile.encoding=UTF-8</jvmFlag>
                        <jvmFlag>-XX:+UseG1GC</jvmFlag>
                        <jvmFlag>-verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCTimeStamps -Xloggc:/var/log/gc.log</jvmFlag>
                        <jvmFlag>-Djava.security.egd=file:/dev/./urandom</jvmFlag>
                    </jvmFlags>
                </container>
            </configuration>
        </plugin>
    </plugins>
</build>

然后推送到我自己私有的docker仓库，就OK了

mvn -DsendCredentialsOverHttp=true jib:build

在不同的机器上运行

# On my test machine, I want to run like this
docker run --name test-xxx -d \
    -p 8080:8080 -p 9080:9080 \
    -e JAVA_OPTS="-Xms256m -Xmx256m -Dspring.profiles.active=test -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9080" \
    -v ~/logs:/logs \
    self-ip:port/xxx/yyy

# on my production machine, I want to run like this
docker run --name prod-xxx -d \
    -p 8080:8080 \
    -e JAVA_OPTS="-server -Xms1G -Xmx1G -Dspring.profiles.active=prod" \
    -v /mnt/logs:/logs \
    self-ip:port/xxx/yyy

当我在测试机上运行时，它失败了

docker container ls -al
CONTAINER ID    IMAGE   COMMAND                  CREATED         STATUS                     PORTS    NAMES
XXXXXXXXXXXX    xxx     "java $JAVA_OPTS -Df…"   3 seconds ago   Exited (1) 2 seconds ago            test-xxx

我的期望是这样

# test machine
java -Xms256m -Xmx256m -Dspring.profiles.active=test \
    -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9080 \
    -Dfile.encoding=UTF-8 -XX:+UseG1GC -verbose:gc \
    -XX:+PrintGCDetails -XX:+PrintGCDateStamps \
    -XX:+PrintGCTimeStamps -Xloggc:/logs/gc.log \
    -Djava.security.egd=file:/dev/./urandom \
    -cp /app/resources:/app/classes:/app/libs/* \
    xxx.yyy.MainClass

# production machine
java -server -Xms1G -Xmx1G -Dspring.profiles.active=prod \
    -Dfile.encoding=UTF-8 -XX:+UseG1GC -verbose:gc \
    -XX:+PrintGCDetails -XX:+PrintGCDateStamps \
    -XX:+PrintGCTimeStamps -Xloggc:/logs/gc.log \
    -Djava.security.egd=file:/dev/./urandom \
    -cp /app/resources:/app/classes:/app/libs/* \
    xxx.yyy.MainClass

我应该如何配置它？container --> environment还是dockerClient --> environment？
我在文档中没有找到任何相关的例子，它们都只是一句话

更新 1

嗨@Haran我修改<jvmFlag>$JAVA_OPTS</jvmFlag>并JAVA_TOOL_OPTS重新推送

并在测试中运行

docker container rm test-xxx
docker run --name test-xxx -d \
    -p 8080:8080 \
    -e "JAVA_TOOL_OPTIONS=-Xms256m -Xmx256m -Dspring.profiles.active=test -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9080" \
    ip:port/xx/yy

它也运行失败

$ docker container ls -al
CONTAINER ID    IMAGE   COMMAND                       CREATED         STATUS                     PORTS    NAMES
XXXXXXXXXXXX    xxx     "java $JAVA_TOOL_OPTS -Df…"   3 seconds ago   Exited (1) 2 seconds ago            test-xxx

然后我删除 $JAVA_TOOL_OPTS 并重复上面的 repush 和docker rm & run，运行成功，但没有自定义环境

$ docker exec -it test-xxx ps auxf
PID   USER     TIME  COMMAND
    1 root      0:05 java -Dfile.encoding=UTF-8 -XX:+UseG1GC -verbose:gc -XX:+P
   59 root      0:00 ps auxf


$ docker ps --no-trunc
CONTAINER ID    IMAGE  COMMAND                                                                                                                                                                                                                                              CREATED             STATUS              PORTS                    NAMES

该命令的引号docker -e ...在内部和外部之间没有区别。

$ docker run --name test-xxx -d -p 8080:8080 \
    -e JAVA_TOOL_OPTIONS="-Xms256m -Xmx256m -Dspring.profiles.active=test -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9080" \

解决方案

设置 JVM 参数，只需JAVA_TOOL_OPTIONS在运行时设置即可。实际上，我可以从您的更新中看到您已经尝试过。

$ docker run ... -e "JAVA_TOOL_OPTIONS=..."

大多数 JVM 会自动获取 JAVA_TOOL_OPTIONS 环境变量，因此您不需要将里面的内容JAVA_TOOL_OPTIONS作为命令行参数传递给java二进制文件。您可以在您的机器上本地验证此行为（在容器内部或外部）：

$ JAVA_TOOL_OPTIONS=-Xmx256m java ABCD # no need to pass extra arguments
Picked up JAVA_TOOL_OPTIONS: -Xmx256m
Error: Could not find or load main class ABCD

$ docker run -e "JAVA_TOOL_OPTIONS=-Xmx256m" --entrypoint java openjdk:11 ABCD
Picked up JAVA_TOOL_OPTIONS: -Xmx256m
Error: Could not find or load main class ABCD
Caused by: java.lang.ClassNotFoundException: ABCD

因此，只需在运行时定义（并且JAVA_TOOL_OPTIONS您已经使用.docker run -e<jvmFlags><entrypoint>

最后，是JAVA_TOOL_OPTIONS，不是JAVA_TOOL_OPTS。
