from ec2 instance used to build docker image

  • After the inital start up, you might want to check the startup logs to check for errors: vi /var/log/cloud-init-output.log
  • Login to aws: aws configure
  • Login to ecr: sudo $(aws ecr get-login --region us-east-1 --no-include-email)
  • Tag docker image: sudo docker tag .dkr.ecr.us-east-1.amazonaws.com/nodetest -- Note: you can go to AWS ECR repos to get URL above.
  • Push docker to ecr: sudo docker push .dkr.ecr.us-east-1.amazonaws.com/
  • Update lambda function with latest docker image (this has to be done manually)
