I've followed the instructions on the Amazon ECR Plugin (https://wiki.jenkins-ci.org/display/JENKINS/Amazon+ECR, which simply instructs a user to install the Amazon ECR configure the Docker Build & Deploy plugin), but Jenkins is unable to authenticate with ECR.
The error message produced is:
denied: Your Authorization Token has expired. Please run 'aws ecr get-login' to fetch a new one.
Any advice anyone can provide is greatly appreciated.
