Argo Workflows build demo get commitid

基于上一个例子，本例中将使用 commitid 来作为 image的tag

其中涉及了

1. 如何在task之间传递 parameter
2. 如何获取 commitid

因为 command 和 entrypoint 都无法使用 管道和重定向 （ args 都以参数形式提供 ）
所以这里使用了一个 ubuntu + shell 脚本的方式来 将 commitid 写入缓存文件

/getcommitid.sh

touch /work/$1/commitid.txt
git -C /work/$1 rev-parse HEAD > /work/$1/commitid.txt
ls /work
ls /work/$1
cat /work/$1/commitid.txt

Dockerfile

FROM ubuntu
RUN apt -y update && apt install -y git
COPY getcommitid.sh /
RUN chmod 777 /getcommitid.sh

然后yaml文件内容

这里通过 output parameter 进行传递参数，请注意加粗的部分
