kubectl create secret docker-registry regcred \
  --docker-server=<aws-account-id>.dkr.ecr.<aws-region>.amazonaws.com \
  --docker-username=AWS \
  --docker-password=$(aws ecr get-login-password) \
  -o yaml
  
# This creates the regcred secret and at the same time output YAML to standard output which you
# can store elsewhere. In my case I have two machines, one having aws and the other having kubectl.
# So I run "aws ecr get-login-password" on one machine and paste the result to replace
# $(aws ecr get-login-password).
