When i push image to private register（harbor）：

Below is a simple jenkinsfile：
pipeline {
agent {
node {
label 'go'
}
}
stages {
stage('构建并推送镜像') {
agent none
steps {
sh '''cat > Dockerfile <<EOF
FROM nginx:latest
EOF
'''
container('go') {
sh 'docker build --network host -t harbor.wxtest.com/public/nginx-test:v1adfea .'
withCredentials([usernamePassword(credentialsId : 'harbor-new' ,passwordVariable : 'DOCKER_PASSWORD' ,usernameVariable : 'DOCKER_USERNAME' ,)]) {
sh 'echo "asdfea342dfFD3" | docker login http://harbor.wxtest.com -u "admin" --password-stdin'
sh 'docker push harbor.wxtest.com/public/nginx-test:v1adfea'
}
}
}
}
}
}
This harbor is installed in Kubernetes through helm, and no certificate is configured; it needs to be used separately from the previous harbor (production environment).
I googled for a long time and didn't find a similar question, hope someone here can help me.

Answer 1

The error status shown shows that the layer already exists if you have tried to remove all the available images and upload and it still is showing the status.
try creating a new repo and check by pushing the image there so that we can make confirmation about the values we provided by Jenkins file is valid and can be used to push accordingly.

Answer 2

It might be caused by one of the image layers(blob) corrupted in the file system. you could find and delete this blob and try repush
