Your Makefile might look something like the following. The important bit is the docker_auth step.

Code Block
$ cat Makefile   
.PHONY: docker_build docker_tag docker_auth docker_push
.DEFAULT_GOAL := docker_tag

docker_build:
        docker build . -f Dockerfile -t edxops/ecr-cred-helper

docker_tag: docker_build
        docker tag edxops/ecr-cred-helper edxops/ecr-cred-helper:$$TRAVIS_TAG
        docker tag edxops/ecr-cred-helper edxops/ecr-cred-helper:$$TRAVIS_COMMIT

docker_auth:
        echo "$$DOCKER_PASSWORD" | docker login -u "$$DOCKER_USERNAME" --password-stdin

docker_push: docker_tag docker_auth ## push to docker hub
        docker push 'edxops/ecr-cred-helper:latest'
        docker push "edxops/ecr-cred-helper:$$TRAVIS_COMMIT"
        docker push "edxops/ecr-cred-helper:$$TRAVIS_TAG"
