这里我看了下，这个地方 compose 文件里写 bool 值是其实不正确的，可能是我使用的 compose 插件版本做了额外的转换，能够正常使用，但是实际这个写法不是标准的。

YAML 文件支持 bool 类型的 value，但是对于环境变量来说， linux 环境变量都是字符串，如果在 compose 文件里用 map 的形式编写 env，value 又是 bool类型的话，解析器就会把那个值解析为 bool，但是linux 的环境变量需要的字符串，这个地方类型不匹配，你贴的报错日志就是这个情况。

docker 官方的文档是有提到环境变量所有的 bool 值都必须要用引号包起来，参见这里
https://docs.docker.com/compose/compose-file/compose-file-v3/#environment

看起来是个已知的问题。保险起见我后续会把项目中这种写法全部改掉

我查询了一下 Docker Compose 相关的更新日志：

https://docs.docker.com/compose/release-notes/#170
1.7.0 Breaking Changes 中的第二条

Booleans are no longer allows as values for mappings in the Compose file (for keys environment, labels and extra_hosts). Previously this was a warning. Boolean values should be quoted so they become string values.

https://docs.docker.com/compose/release-notes/#bug-fixes-26
1.19.0 Bug fixes 中的最后一条

Added better validation of labels fields in Compose files. Label values containing scalar types (number, boolean) now get automatically converted to strings

所以这解释了在 labels 字段中的的布尔值不用引号包起来不会报错，而在 environment 字段中的布尔值不用引号包起来会报错的原因。
估计您应该使用了什么插件让其自动添加了引号。
