I days old with Groovy so please bear with me. I bought a Groovy book but this subject is of course not discussed in it.
We use a Jenkins file to set up stages, and we have this stage def demoImage stage("Build ECS Docker Image") { dir('demo') { docker.withRegistry("https://${dockerUrl}", ecrCredentialsId) { demoImage = docker.build("${dockerUrl}/some-name- ${env.EnvironmentKey}-${env.DBName}") } } } I assume demoImage contains some image information, like the image ID that I need for later? How do I get the image ID from demoImage? Where would this be documented online? I googled, but I don't necessarily how to look what I'm looking for. Thanks, Chris
