需求
在gitlab-ci.yaml文件中獲取變更文件的目錄脚乡，獲取目錄名后做其他操作，比如在不同目錄docker build
原理
根據(jù) git diff 命令的輸出，用 linux 命令做處理, 例如下命令
? git diff --name-only | awk -F/ '{print $1}' | sort -u
.gitlab-ci.yml
Dockerfile
README.md
ansible
jenkinks_pipeline.groovy
scripts
spike_hour
wohle_hour_one_day
可以看到上述結(jié)果是,獲取的包括文件名稱和目錄名，需要在借助shell腳本侦鹏，分辨出目錄
if [ ! -d scripts ]; then
continue
fi
實(shí)現(xiàn)
節(jié)選自 gitlb-ci.yaml
