When a docker image is used as an agent at the pipeline level, `image.pull()` is called automatically to check for a newer version. E.g.:
pipeline { agent { docker 'microsoft/dotnet' } stages { stage('x') { steps { sh '...' } } } }
However, when a docker image is used as an agent at the stage level, `image.pull()` is never called, so potentially old images are used instead.E.g.:
pipeline { agent none stages { stage('x') { agent { docker 'microsoft/dotnet' } steps { sh '...' } } } }
Is it possible to automatically call `image.pull()` as well, or at least provide an option flag to state you want this behaviour?
I believe the code that affects this is: https://github.com/jenkinsci/pipeline-model-definition-plugin/blob/824b3b7a96cc9d4fc6fc636caccaed3d39343cfd/pipeline-model-definition/src/main/resources/org/jenkinsci/plugins/pipeline/modeldefinition/agent/impl/DockerPipelineScript.groovy#L42
