因此，我在笔记本电脑上使用 vagrant 完成了 3 节点核心操作系统设置。我正在关注他们的快速入门指南。https://coreos.com/docs/quickstart/。
现在，当我运行 hello.service 并检查它的状态时，它告诉我该服务处于非活动状态/已死。
core@core-02 ~ $ fleetctl status hello.service
● \x22hello.service\x22.service
Loaded: not-found (Reason: No such file or directory)
Active: inactive (dead)
虽然日志和 docker ps 输出似乎暗示一切正常：
core@core-02 ~ $ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3b338ba5085b busybox:latest "/bin/sh -c 'while t 2 minutes ago Up 2 minutes hello
core@core-02 ~ $ fleetctl journal hello.service

知道我的环境做错了什么吗？TIA。这是 hello.service：
core@core-02 ~ $ cat hello.service
