错误：在文件“./docker-compose.yml”中，卷必须是映射，而不是数组

我得到这个错误（错误：在文件'./docker-compose.yml'，卷必须是一个映射，而不是一个数组），当我运行“docker – 组成”命令。

我的docker-compose.yml文件看起来像这样。

version: '2' web: build: . ports: - "5000:5000" volumes: - .:/code ngnix: image: "ngnix:alpine"

和我的docker文件看起来像这样

我能做些什么，如果有更改id .yml文件或Dockerfile

Answer 1

您的docker-compose.yml文件需要正确缩进 – 空格表示YAML文件中的结构。 我怀疑你会想要这样的东西：

 version: '2' services: web: build: . ports: - "5000:5000" volumes: - .:/code ngnix: image: "ngnix:alpine" 

没有缩进，你会得到错误信息
