Docker go作业从何处获取环境变量？

当我在go代理上执行printenv命令时

go@05f749b73185:/tmp$ printenv
HOSTNAME=05f749b73185
SHELL=/bin/bash
USER=go
LS_COLORS=
MAVEN_VERSION=3.3.9
MAIL=/var/mail/go
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
MAVEN_HOME=/usr/share/maven
PWD=/tmp
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/

SHLVL=2
LOGNAME=go
LC_CTYPE=en_US.UTF-8
LESSOPEN=| /usr/bin/lesspipe %s
LESSCLOSE=/usr/bin/lesspipe %s %s
_=/usr/bin/printenv

但是当我从作业内部执行printenv命令时，我得到了这个结果

如果查看JAVA_HOME环境变量，则在登录机器时，作业调用和直接调用之间是不同的。 这可以通过在管道中设置环境变量来解决，但是我如何配置我的go服务器和go代理，以便不必这样做？如果我想使用另一个JDK作为默认值呢

JAVA_HOME环境变量来自何处？

您是否选中了

/etc/default/

在此文件中，您可以定义代理的默认值，还可以使用

export

命令定义环境变量
