Question

在为我的yml文件运行docker-compose时，我不断收到服务“图像”错误。

我在线上进行了研究，看来这主要是一些格式化错误。我已经通过yAML linter运行yml，并且没有错误。

预计将下载图像并启动容器

错误是：错误：在文件'。\ docker-compose.yml'中，服务'image'必须是映射，而不是字符串。

Answer 1

此问题是由于缩进而发生的。

docker-compose由于错误的缩进而像服务一样image。

我修改了文件并成功启动了已配置的容器：

version: "3.5"

services:
        server:
                image: postgrest/postgrest
                ports:

                links:
                         - db:db
