jenkins添加git凭证

插件管理

需要一下插件支持

在凭据管理中添加全局凭证

方式一： SSH认证

生成sshkey
终端输入

ssh-keygen -t rsa -C 'foo.bar@xxx.com'

一路回车

jenkins@jenkins-0:/$ ssh-keygen -t rsa -C 'root@git'
Generating public/private rsa key pair.
Enter file in which to save the key (/var/jenkins_home/.ssh/id_rsa): 
Created directory '/var/jenkins_home/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/jenkins_home/.ssh/id_rsa
Your public key has been saved in /var/jenkins_home/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:F5R4bnPjBLCUu8kUwhsoPkQnpGxIzbh72rk7xyGBz+g root@git
The key's randomart image is:
+---[RSA 3072]----+
| +B .o  o+..     |
|+oo=. +.+o+      |
|o=o.   +.=..     |
|.oo.  . o +.+    |
|  =..  oS+.= .   |
| o = .  +.  .    |
|. + + .          |
| E + o           |
|   o=            |
+----[SHA256]-----+

最终会在用户目录/.ssh/ 中生成公钥和私钥（id_rsa.pub和id_rsa）

Your identification has been saved in /var/jenkins_home/.ssh/id_rsa
Your public key has been saved in /var/jenkins_home/.ssh/id_rsa.pub

cat /var/jenkins_home/.ssh/id_rsa.pub
ssh-rsa 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 root@git

将id_rsa.pub内容拷贝出来，然后打开github，进入setting-> SSH and GPG keys 点击New SSH key

在Jenkins中添加凭证
选择SSH Username with private key认证方式

将cat /var/jenkins_home/.ssh/id_rsa内容粘贴到key（全部id_rsa得内容）

方式二： 用户名密码方式认证
选择Username with password填写你的git用户名密码同样可以
