Jenkins Pipeline push the Docker Image - docker

Question

I'm trying to push my docker image after building source code, when jenkins push images to docker Hub Registry i am getting below error.
Pipeline Script
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}"
}
}

If you have dot(.) in your image name before the slash, docker treats it as the registry name. So docker push is trying to push to registry named devopsimage.azure. If you actually want to push to Docker Hub instead, remove the dot from the image name. If you want to push to registry named devopsimage.azure, then there is a DNS issue in resolving this registry from your build machine.
