docker - docker compose build 未传递 compose 文件中定义的构建参数

问题描述

测试 Dockerfile

FROM alpine:latest
RUN env
ARG buildno
RUN env

RUN echo "Buildno: ${buildno}"

ENV buildno=${buildno}
RUN echo "Buildno: ${buildno}"

示例 docker-compose.yml

version: "3.9"
services:
  db:
    build:
      context: .
      args:
        buildno: 1

docker compose build不承认我通过了一个论点

如果我通过 cli 传递值，--build-arg尽管它被拾取，那么这似乎是 docker compose 的问题？

buildno 值在第 3 行定义后按预期显示，并按应有的方式出现在环境变量中。有什么想法吗？我使用我的 Windows 客户端和我的 WSL2 客户端得到了相同的结果。

解决方案

这似乎是一个已知问题，docker compose而不是docker-compose
