以前在jenkins中配置ssh key，好像很麻烦，内心一直很抗拒，一般都是用username/passowrd 模式。这次用git.code.tencent.com,没有用户名/密码了，被迫使用ssh key。重新试了一下，发现非常简单。

Generate ssh key

ssh-keygen -t rsa

Add ssh public key in git account

cat ~/.ssh/id_rsa.pub

Add ssh private key into jenkins

cat ~/.ssh/id_rsa

Go to jenkins home ->凭据 -> 全局 -> 添加凭据

选择类型 SSH Username with private key

Input username just as your like, input Private key from clipboard

Create task to verify credentials
