Hi @saspath, and welcome to the Jenkins community!

Based on the docker variable documentation in my local Jenkins instance (available at https://jenkins-url/pipeline-syntax/globals#docker), I believe you need to be using def imageId = dockerImage.id instead of trying to call a method getImageId(). A quick reading of the Docker Pipeline plugin source confirms that as well. Give that a try and let us know how it goes!

dockerImage.id is returning just the registry “22222222222.dkr.ecr.us-east-1.amazonaws.com/test-repo” ,
I wanted shaID so used below code.
imageID = sh(returnStdout: true, script: “docker inspect -f ‘{{.ID}}’ ${registry}”).trim()

Thank you for everything.
