Question

我有一个Ansible playbook，期望在ansible_env中找到JAVA_HOME。当我在远程安装Oracle Java 8的Ubuntu 16.04主机上运行它时，JAVA_HOME和其他Java变量都丢失了。但是，当我使用 ansible -K --become -m setup -c local localhost 在目标主机上本地收集事实时，我看到了它们。我的管理工作站和目标主机都是通过APT安装运行Ansible 2.5的Ubuntu 16.04。导致差异的是什么？当Ansible远程运行时，如何让JAVA_HOME可见？

请注意，问题不是关于如何在剧本执行期间设置JAVA_HOME，也不是关于调用shell的变通方法。我试图理解为什么JAVA_HOME并不存在于人们期望从一开始就找到它的地方。

对我的fedora进行测试，如果你将JAVA_HOME放到.bash_profile，Ansible将不会接受它。但是如果你把它放在.bashrc文件中，它将显示为ansible_env。

PS。当您开始收集事实到localhost时，它将继承您从shell获得的所有env变量。如果您在将playbook运行到localhost之前执行了export MY_VAR=YitzikC，则会在ansible_env中看到该变量。

远程收集事实时，JAVA_HOME不在Ansible环境中
