maven - jib-maven spring boot 配置文件

Question

在我的springboot项目中，一共有三个配置文件

application.yml --> used in local development
application-test.yml --> running in a test environment
application-prod.yml --> running in a production environment

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>

然后推送到我的私有(private)docker存储库，就可以了

mvn -DsendCredentialsOverHttp=true jib:build

在不同机器上运行

# 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，失败

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

我的期望是这样的

# 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或dockerClient --> environment ？
我在文档中没有找到相关的例子，都只是一句话

嗨@Haran，我修改了<jvmFlag>$JAVA_OPTS</jvmFlag>至JAVA_TOOL_OPTS并拒绝

并运行测试

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，但是没有自定义环境

$ 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

$ docker ps --no-trunc

docker -e ... 的引号内部和外部的命令没有区别。

Answer 1

要设置JVM参数，只需设置 JAVA_TOOL_OPTIONS在运行时。实际上，我从您的更新中可以看出您已经尝试过此操作。

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

大多数 JVM 会自动获取 JAVA_TOOL_OPTIONS 环境变量，因此您无需传递 JAVA_TOOL_OPTIONS 中的内容。作为 java 的命令行参数二进制。您可以在您的计算机上本地验证此行为(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

所以，只需定义 JAVA_TOOL_OPTIONS在运行时(并且您已经使用 docker run -e 完成了它)，并且不定义 <jvmFlags>或修改<entrypoint> .

最后是JAVA_TOOL_OPTIONS ，不是JAVA_TOOL_OPTS .
