Docker hub自动构建，丢失变量

Question

我已经使用必要的变量设置了“BUILD ENVIRONMENT VARIABLES”，并添加了hooks/build：

#! /bin/bash

docker build \
  --build-arg HBASE_VERSION="${HBASE_VERSION}" \
  -f "${DOCKERFILE_PATH}" \
  -t "${IMAGE_NAME}" .

不是在构建过程中传递，看看日志输出：

可见缺少变量，我需要做些什么才能解决这个问题？

Answer 1

你能试试ARG和ENV吗？

ARG HBASE_HOME="default_value"
ENV HBASE_HOME="$HBASE_HOME"

在你的Dockerfile中

build-arg VALUE应覆盖“default_value”。

Answer 2

hooks/build文件需要生活在Dockerfile的同一目录中。

我的项目有几个子文件夹，每个文件夹都有一个Dockerfile。
