# 基础环境
# 此配置作用：设置过后，每一个步骤都会公用此空间，在此就是 /drone/go/src/workspace
# 比如：在镜像golang:1.14-alpine会有/drone/go/src/workspace目录，此目录下就会包含
# 项目源代码。同时，在执行了步骤app-build过后，会在此目录下生成 demo文件夹，文件夹内部会有
# demo可执行文件及Shanghai、ca-certificates.crt 文件
# 而后，在执行image-build后，同样的会有/drone/go/src/workspace路径，并且，也会包含上述
# 步骤生成文件，所以，在Dockerfile文件内，可以直接使用 COPY 命令复制相关文件。
