【问题描述】：
我有一个main.go 文件，用于运行一个应用程序，该应用程序启动一个服务器，该服务器公开一个端口，我可以从中运行端点。我试图将它 dockerise 并尽可能制作容纳应用程序和数据库的工作容器，但在运行 docker-compose up -d 之后我似乎仍然必须运行 go run main.go。
// present folder structure
.
├── cities.json // holds records of all city names
├── docker-compose.yaml
├── dockerfile
├── go.mod
├── go.sum
├── localmon.sh // bash script that does a mongoimport to import all records from cities.json into the db
├── main.go
└── README.md
有人告诉我，我可能必须映射一个卷，知道它的位置并让它执行。另一种选择（更复杂）是 bash 脚本（或两者兼而有之？）
我有点不确定如何去做，或者我现在应该如何处理我的 compose 文件和 dockerfile。

嗨 Lazlo，恐怕我不明白问题出在哪里。能否请您说出您想做的事情以及不符合您预期的事情？
-
为什么要在容器外运行 main.go？您使用哪个命令来启动您的应用程序的容器？
-
嗨，安德烈。我要做的是运行
docker compose up -d并启动容器。这会从 compose 文件中启动应用程序和 mongo-test db。之后，我运行go run main.go以使应用程序正常工作，但事实并非如此。我希望该部分已经由容器处理，而不是我必须手动处理。基本上，我希望main.go文件作为docker-compose up -d命令的一部分运行。希望这更有意义。 -
在容器外运行应用程序违背了创建容器的目的。这不是一种解决方法:) 您在您的dockfefile 中正确指定了 CMD ["./main"]。您的应用程序似乎在启动时崩溃（无法连接到数据库？）。请使用“docker-compose logs
”命令查看日志。 -
另一个问题：如何测试您的应用是否已启动？
