Therefore use a command below that will retrieve, decode, and convert the <code>authorization IAM token</code> into a pre-generated <code>docker login</code> command. Therefore produced login credentials will assume your current IAM User/Role permissions. If your current IAM user can only pull from ECR, after login with <code>docker login</code> you still won't be able to push image to the registry. Example error you may get is <code>not authorized to perform: ecr:InitiateLayerUpload</code>
