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

Question

我在运行“ docker-compose up”命令时遇到此错误（错误：在文件“ ./docker-compose.yml”中，卷必须是映射，而不是数组）。

我的docker-compose.yml文件如下所示。

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

我的码头工人文件看起来像这样

我应该怎么做，是否应该更改id .yml文件或Dockerfile中

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。 我怀疑您会想要这样的东西：

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

没有缩进，您将收到错误消息
