Question

它在“ Building blahblah”上停留了大约18分钟以上，有时还会更长……

等待了很长时间后，所有东西都建立起来并运行起来。

docker-compose --verbose build 没有给我太多信息。

Docker Engine-社区引擎版本：19.03.8

Answer 1

这就是为什么上下文太大或太深的原因。尝试创建一个空文件夹，将docker-compose.yml和Dockerfile移到那里，然后

docker-compose build
docker-compose up -d

问题通常在您的上下文中包含大量文件夹，符号链接和/或深度过大时发生。上下文是您的Dockerfile所在的位置：

version: '3.8'
services:
  your-srv:
    build:
      context: .
      dockerfile: Dockerfile
    image ...

Answer 2

在Docker构建上下文中创建一个.dockerignore文件（如果未指定，则与Dockerfile / docker-compose.yml相同）

在其内部，您的目录/文件可从Docker上下文中忽略。

例如对我来说是

data = [[45.0, 58.0, 45.0, 520.0], [45.0, 58.0, 754.0, 58.0], ... [562.0, 520.0, 562.0, 581.0], [563.0, 450.0, 629.0, 450.0]] #Directly appending an element to item will impact original dataset, #Since list is reference data structure, for item in data: item.append(2) print(data) [[45.0, 58.0, 2, 45.0, 520.0, 2], [45.0, 58.0, 2, 754.0, 58.0, 2], ... [562.0, 520.0, 2, 562.0, 581.0, 2], [563.0, 450.0, 2, 629.0, 450.0, 2]]

稍后我的docker-compose会作为卷映射。

或者您可以指定要使用的Build上下文，例如一个文件夹，其中包含您需要在Dockerfile中添加/使用的内容。您要映射到运行容器中的代码/文件的任何卷都不应位于同一目录中，或者应位于.dockerignore中。

可以将构建上下文配置为docker-compose.yml中的另一个路径

html

因此，您可以将docker目录作为上下文，并在其外部添加Dockerfile和docker-compose.yml，然后将src目录和其他内容放置在其他位置。

docker-compose构建需要很长时间，构建时是否可以启用冗长/调试日志？
