Argo CICD demo step3

构建镜像之后，更新yaml repository触发 argo cd

核心脚本只有一个

cat /work/commitid.txt | xargs -i sed 's/:[0-9A-Za-z]\{40,40\}$/:{}/' /argogithubsource_cd/argoapp.yaml

我们创建一个 main.sh

#!/bin/bash

git config --global user.email $USER_EMAIL
git config --global user.name $USER_NAME

echo $GIT_URL
echo $REPO
echo $BRANCH

rm -rf /work/$REPO
git clone -b $BRANCH $GIT_URL
pwd
echo "ls /"
ls /
echo "ls REPO"
ls $REPO
echo "============"/$REPO/$1"================"
cat /$REPO/$1
echo "============/work/commitid.txt================"
cat /work/commitid.txt
cat /work/commitid.txt | xargs -i sed -i 's/:[0-9A-Za-z]\{40,40\}$/:{}/' /$REPO/$1
cat /work/commitid.txt | xargs -i sed -i 's/:mockup_tag_name/:{}/' /$REPO/$1
echo "============"/$REPO/$1"================"
cat /$REPO/$1

cd /$REPO && git add ./*
cd /$REPO && cat /work/commitid.txt | xargs -i git commit -m {} ./*
cd /$REPO && git push

其中主要的配置

5个环境变量
$GIT_URL = https://USERNAME:PASSWORD@github.com/zl86790/argogithubsource_cd.git
$REPO = argogithubsource_cd
$BRANCH = main
$USER_EMAIL = YOUREMAIL@google.com
$USER_NAME = YOURNAME
一个参数
$1 = argoapp.yaml

在提交了新代码之后，这个容器会使用上面的脚本根据前面步骤生成的 commitid，自动更新 deply的git仓库，修改 应用的 tag name，并且提交到部署代码仓库

最后通过 deploy 步骤进行部署
