一、jenkins集成ansible步骤
1、在jenkins全局配置工具中配置ansible的执行路径，如下：

2、创建一个pipeline的流水线，如下：
jenkins与gitlab集成步骤省略



3、gitlab创建Jenkinsfile文件如下：
jenkinsfile内容如下：

pipeline {   
    agent {  
        label 'k8s-master'
        }    
    stages { 
        stage('daemon ansible') {
            steps {
                ansiblePlaybook (
                playbook: "${env.WORKSPACE}/daemon.yaml",
                inventory: "${env.WORKSPACE}/hosts",
                credentialsId: "f1d56643-64f3-45f1-ab86-adc116644828"
                )
            }                                                                                                                                                              
        }    
    }        
}      

上传文件至gitlab，如下：

[root@weizb-3 jenkins-ansible]# git add .
[root@weizb-3 jenkins-ansible]# git commit -m "update daemon.yaml"
[master df95780] update daemon.yaml
 2 files changed, 2 insertions(+), 2 deletions(-)

Branch master set up to track remote branch master from origin.

4、jenkins触发构建，如下：
