How to push Docker image to ECR in Jenkins? - amazon-web-services

Question

I am working with Jenkins. I am trying to push image to ECR. I am using local Docker to build the images.
Below is my Jenkins file:
pipeline {
agent any
stages {
stage('Build') {
steps {
bat 'docker build -t sampleapp -f SampleApp/Dockerfile .'
}
}
stage('Push image') {
steps {
withDockerRegistry([url: "https://536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository",credentialsId: "ecr:ap-southeast-2:demo-ecr-credentials"]) {
bat 'docker push sampleapp:latest'
}
}
stage('Deploy') {
steps {
echo 'Deploying....'
}
}
}
}
In the above code, I am able to build and create an image. In the second stage, I am facing the issues. I am getting the below error:
$ docker login -u AWS -p ******** https://536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository
WARNING! Using --password via the CLI is insecure. Use --password-stdin.

C:\Program Files (x86)\Jenkins\workspace\SampleAppPipeLine>docker push sampleapp:latest
The push refers to repository [docker.io/library/sampleapp]

Can someone help me to fix this issue? Any help would be appreciated.
Thanks.

Default repository of docker.io is being hardcode is : docker.io/library/
So for AWS ECR repo, you should :
docker build -t test-repository .
docker tag test-repository:latest
536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository:latest
docker push 536703334988.dkr.ecr.ap-southeast-2.amazonaws.com/test-repository:latest
Make sure test-repository repo is already create on ECR.
