需求
在gitlab-ci.yaml文件中获取变更文件的目录，获取目录名后做其他操作，比如在不同目录docker build
原理
根据 git diff 命令的输出，用 linux 命令做处理, 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
可以看到上述结果是,获取的包括文件名称和目录名，需要在借助shell脚本，分辨出目录
if [ ! -d scripts ]; then
continue
fi
实现
节选自 gitlb-ci.yaml
build_docker_image:
stage: dockerise
tags:
- delv-docker
image: docker
services:
- docker:dind
variables:
REPOSITORY_URL: *
KUBERNETES_SERVICE_ACCOUNT: gitlab-runner
DOCKER_HOST: tcp://localhost:2375
DOCKER_DRIVER: overlay2
DOCKER_TLS_CERTDIR: ""
script:
- >
git fetch origin $CI_MERGE_REQUEST_TARGET_BRANCH_NAME;
# git diff 循环整个输出
for dir in $(git diff --name-only $CI_COMMIT_SHA origin/$CI_MERGE_REQUEST_TARGET_BRANCH_NAME | awk -F/ '{print $1}' | sort -u); do
# 判断是否是文件目录类型`dictionary`,
if [ ! -d $dir ]; then
#如果不是 则跳过剩下的步骤
continue
fi
# 是 `dictionary` 则进入
cd $dir
if [ ! -f Dockerfile ]; then
echo "WARN: no Dockerfile in directory $dir, skipping"
continue
fi
export APP_NAME_BUILD=$(echo $dir| sed "s/\//_/g" | sed "s/-/_/g")
export VERSION=${CI_JOB_ID}_$(echo $CI_COMMIT_SHA | head -c 8)
docker build -t $REPOSITORY_URL:$APP_NAME_BUILD-$VERSION .
docker push $REPOSITORY_URL:$APP_NAME_BUILD-$VERSION
echo "#########################################################################"
echo "# Pushed Docker Image: $REPOSITORY_URL:$APP_NAME_BUILD-$VERSION"
echo "#########################################################################"
done
only:
refs:
- master
changes:
- Dockerfile
- scripts/*
- .gitlab-ci.yml
