外置的gitlab如何在kubesphere的devops流水线中配置ssh凭证

akun

创建gitlab凭证，ssh类型，用户root，私钥贴进去，密码root密码，跑流水线的时候显示失败，没有输出日志
Jenkinsfile文件内容如下：
pipeline {
agent {
node {
label ‘base’
}
}

parameters {
    string(name:'TAG_NAME',defaultValue: '',description:'')
}

    environment {
    DOCKER_CREDENTIAL_ID = 'harbor-id'
    GITLAB_CREDENTIAL_ID = 'gitlab-id'
    KUBECONFIG_CREDENTIAL_ID = 'kubeconfig-id'
    REGISTRY = 'reg.xthklocal.cn'
    HARBOR_NAMESPACE = 'xthk-online'
    GITLAB_ACCOUNT = 'xthk-online'
    APP_NAME = 'user-center-service-background'
    PROJECT_GIT='user_center_service_background.git'
    K8S_NAMESPACE='environment1'
}


    stages {
    stage ('checkout scm') {
        steps {
            checkout(scm)
        }
    }
    
     stage('push with tag'){
      when{
        expression{
          return params.TAG_NAME =~ /v.*/
        }
      }

     steps {
       container('base') {
         input(id: 'release-image-with-tag', message: 'release image with tag?')
         withCredentials([sshUserPrivateKey(credentialsId : 'gitlab-id' ,passwordVariable : 'GIT_PASSWORD' ,usernameVariable : 'GIT_USERNAME' ,)]) {
           sh 'git config --global user.email "kubesphere@yunify.com" '
           sh 'git config --global user.name "kubesphere" '
           sh 'git tag -a $TAG_NAME -m "$TAG_NAME" '
           sh 'git push git@gitlab.xthklocal.cn:$GITLAB_ACCOUNT/$PROJECT_GIT --tags --ipv4'
              }
   
           }
   
        }
      }
    }

}
