Jenkins Pipeline push the Docker Image

Question

我在构建源代码后尝试推送我的 docker 映像，当 jenkins 将映像推送到 docker Hub 注册表时，我收到以下错误。

管道脚本

stage('Build Docker Image') {
container('docker') {
echo 'docker'
sh "docker build -t ${image_name} ."
sh "docker tag ${image_name} ${image_name}:${image_tag}"          
}
} 
stage('Push Docker Image') {
container('docker') {
withCredentials([string(credentialsId: 'DOCKER_HUB_CREDENTIALS', variable: 'DOCKER_HUB_CREDENTIALS')]) {
sh "docker login -u user-name -p ${DOCKER_HUB_CREDENTIALS}"
}
sh "docker push ${image_name}:${image_tag}"
}
}

你能请任何人帮我吗？

如果斜杠前的映像名称中有 dot(.(，docker 会将其视为注册表名称。所以docker push正在尝试推送到名为devopsimage.azure的注册表。如果确实要推送到 Docker Hub，请从映像名称中删除点。如果要推送到名为devopsimage.azure的注册表，则从生成计算机解析此注册表时存在 DNS 问题。
