Question

已为我设置了“ BUILD ENVIRONMENT VARIABLES”和必要的变量，并在hooks/build中添加了以下内容：

#! /bin/bash

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

在构建过程中没有通过，请查看日志输出：

可见变量丢失了，我需要怎么做才能解决此问题？

Answer 1

您可以试试ARG和ENV吗？

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

在您的Dockerfile中

build-arg VALUE应该覆盖“ default_value”。

Answer 2

hooks/build文件必须位于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。

Docker Hub自动构建因缺少变量而下降
