docker compose with build --pull选项

Question

docker-compose中的 docker build --pull。相当于什么？

docker compose reference仅指示构建上下文，构建文件和构建args，但我找不到在docker compose中指定构建选项的语法

感谢

它是相同的docker-compose build --pull：

$ docker-compose build --help
Build or rebuild services.

Services are built once and then tagged as `project_service`,
e.g. `composetest_db`. If you change a service's `Dockerfile` or the
contents of its build directory, you can run `docker-compose build` to rebuild it.

Usage: build [options] [SERVICE...]

Options:
    --force-rm  Always remove intermediate containers.
    --no-cache  Do not use cache when building the image.
    --pull      Always attempt to pull a newer version of the image.
