从CircleCI发布到Dockerhub

Question

我正在尝试构建和发布从CircleCI到Docker中心的图像。当我检查给定分支的代码时，应该构建和发布图像。下面给出的是CircleCI config.yml

version: 2
jobs:
  build:
    working_directory: /dockerapp
    docker:
      - image: docker:17.05.0-ce-git
    steps:
      - checkout
      - setup_remote_docker
      - run:
          name: Install dependencies
          command: |
            apk add --no-cache py-pip=9.0.0-r1
            pip install docker-compose==1.15.0
      - run:
          name: Run tests
          command: |
            docker-compose up -d
            docker-compose run dockerapp python test.py
      - deploy:
          name: Publish application to docker hub
          command: |
            docker login -e $DOCKER_HUB_EMAIL -u $DOCKER_HUB_USER_ID $DOCKER_HUB_PWD
            docker tag dockerapp_dockerapp $DOCKER_HUB_USER_ID/dockerapp:$CIRCLE_SHA1
            docker tag dockerapp_dockerapp $DOCKER_HUB_USER_ID/dockerapp:latest
            docker push $DOCKER_HUB_USER_ID/dockerapp:$CIRCLE_SHA1
            docker push $DOCKER_HUB_USER_ID/dockerapp:latest

最后一步“部署”似乎失败了以下消息。

#!/bin/sh -eo pipefail
docker login -e $DOCKER_HUB_EMAIL -u $DOCKER_HUB_USER_ID $DOCKER_HUB_PWD
docker tag dockerapp_dockerapp $DOCKER_HUB_USER_ID/dockerapp:$CIRCLE_SHA1
docker tag dockerapp_dockerapp $DOCKER_HUB_USER_ID/dockerapp:latest
docker push $DOCKER_HUB_USER_ID/dockerapp:$CIRCLE_SHA1
docker push $DOCKER_HUB_USER_ID/dockerapp:latest
Flag --email has been deprecated, will be removed in 17.06.

有人可以帮助我吗？
