docker - .env 文件被 "sourced"忽略而不是 `docker-compose`

Question

案例:我在docker-compose中启动了一个服务。.env 文件中的所有变量都会被忽略，不会被动态替换，如下所示:

PS C:\workarea\jonathan\myProject> docker-compose up -d myService
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_USER variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_PASSWORD variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The YYYY_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The ZZZ_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_USER variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The XXXXX_PASSWORD variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The YYYY_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The ZZZ_URL variable is not set. Defaulting to a blank string."
time="2021-07-23T15:20:50-04:00" level=warning msg="The DDDDD_ROOT_PASSWORD variable is not set. Defaulting to a blank string."
...

环境:

• Windows 10
• Windows 版 Docker 桌面 3.5.2 (66501)
• WSL 2
• 编写 1.29.2

解决方案包括在“设置”>“实验性功能”中禁用使用 Docker Compose V2，然后“应用并重新启动”:

警告:虽然此选项未选中，但 Docker 会在没有任何用户操作的情况下重新启用它。我在两台不同的笔记本电脑上多次遇到这种情况。
