jenkins 管道中的 docker.withDockerRegistry() 問題

Question

我正在嘗試通過安裝在 kube.netes 上的 jenkins 將 docker 圖像推送到 ecr 存儲庫，我已經創建了所有內容，即 docker 圖像和 ECR 存儲庫。 我有一個 jenkins 管道腳本，它將拉取 docker 圖像並將圖像推送到 ECR。 我正在使用代碼

stage('Push image to ECR'){     
docker.withRegistry("https://807***16.dkr.ecr.us-east-1.amazonaws.com/helloworld", "ecr:us-east-1:ecr") {
                           docker.image('faisalbasha82/helloworld').push('latest')
              }
}

我收到以下錯誤，我認為這與無法正確獲取 docker 命令的環境路徑有關。

[Pipeline] { (Push image to ECR)
[Pipeline] withEnv
[Pipeline] {
[Pipeline] withDockerRegistry
$ docker login -u AWS -p ******** https://807***16.dkr.ecr.us-east-1.amazonaws.com/helloworld
[Pipeline] // withDockerRegistry
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] }
[Pipeline] // podTemplate
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

Jenkins 插件要求docker二進制文件存在於運行節點腳本的代理所在的主機上。 您看到的錯誤是二進制文件不存在時報告的錯誤。 您很可能需要安裝 Docker。
