# 查配置文件路径
docker inspect 容器ID或名字 --format '{{index .Config.Labels "com.docker.compose.project.config_files"}}'

docker inspect appdemo2026 --format '{{index .Config.Labels "com.docker.compose.project.config_files"}}'



docker inspect appdemo2026 
"com.docker.compose.project.config_files": "/Users/dugang/work/dockerdemo/docker-compose.yml",
"com.docker.compose.project.working_dir": "/Users/dugang/work/dockerdemo",



Docker Compose 会在容器上自动打 label，记录：
com.docker.compose.project.config_files：配置文件路径（含文件名）
com.docker.compose.project.working_dir：执行 docker compose up 的目录
默认配置文件名：compose.yaml / compose.yml / docker-compose.yaml / docker-compose.yml
如果容器不是通过 docker compose 启动的，上述 label 不存在，查不到路径。
