Jenkins - 从Jenkins master 本地加载Gl

从目前Jenkins的设计看来，这是不可能的。
但是我们可以变通一下，初始化本地 git 存储库并将其用作SCM来实现需求，而不需要任何远程主机git remote service。

如何配置？ ->

• Jenkins 新建一个文件夹（Folder）
• 找到 Pipeline Libraries -- > Add, 按照如下图方式配置Libraries

注意：Project Repository 为Jenkins master 本地文件目录， 例如“/opt/identity/Jenkins2Library”

• 保存后回到文件夹（Folder）界面

• Jenkins master host 服务器端配置 CentOS-7为例

[root@ Jenkins2Library]# pwd
/opt/identity/Jenkins2Library
[root@ Jenkins2Library]# ll
total 16
-rw-------. 1 root root  101 Aug  2 07:24 Jenkinsfile
drwx------. 2 root root 4096 Aug  2 07:24 Jenkinsfiles
-rw-------. 1 root root   17 Aug  2 07:24 README.md
drwx------. 3 root root   17 Aug  2 07:24 src
drwx------. 2 root root 4096 Aug  2 07:24 vars

• init a git repo 初始化git

git init
git add .
git commit -m "init"

如果遇到要配置email 和name 的情况，就按照提示配置一下
git config --global user.email "you@example.com"
git config --global user.name "Your Name"

• 检查git init 是否生效：

[root@ Jenkins2Library]# git status
# On branch master
nothing to commit, working directory clean
[root@ JenkinsPipeline]# /usr/bin/git ls-remote -h /opt/identity/Jenkins2Library
4a1433d16c5b493c5221ebcd8eef1fb3d93ea88e        refs/heads/master

• 把目录owner 改为Jenkins（重要，否则不工作）

chown jenkins:jenkins -R JenkinsPipeline

• 回到Jenkins文件夹下，创建一个pipeline job

• 配置pipeline:

• 保存配置然后运行
