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
- 如何在task之间传递 parameter
- 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.txtDockerfile
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
