# 系统默认变量 ====================================================================
# 该部分变量为系统根据编译命令默认设置
# `TARGETPLATFORM`：构建后的目标平台信息。如 `linux/amd64`，`linux/arm/v7`，`windows/amd64`
# `TARGETOS`：目标平台信息（TARGETPLATFORM）中的操作系统部分，如：`linux`、`windows`
# `TARGETARCH`：目标平台信息（TARGETPLATFORM）中的平台架构部分，如：`amd64`、`arm`
# `TARGETVARIANT`：目标平台信息（TARGETPLATFORM）中的版本变体部分，如：`v7`
# `BUILDPLATFORM`：用于构建的节点平台信息
# `BUILDOS`：用于构建的节点平台信息（BUILDPLATFORM）中的操作系统部分
# `BUILDARCH`：用于构建的节点平台信息（BUILDPLATFORM）中的平台架构部分
# `BUILDVARIANT`：用于构建的节点平台信息（BUILDPLATFORM）中的版本变体部分

# 可变参数 ========================================================================
# 该部分变量，在编译命令中通过 `--build-arg` 传入；如果未设置，则使用下面对应的默认值
# 依赖镜像下载地址: docker.io (默认) / swr.cn-north-4.myhuaweicloud.com/colovu/
# apt源: default / aliyun / ustc
# 软件包本地服务器: http://pkgs.colovu.com/dist
