Build and Push Docker Image

Introduction
The goal of this section is to show how you can build a docker image and push it to ECR.
It does three basic things:
Logs in to AWS ECR using just-in-time (JIT) AWS credentials from Duplo
Builds and tags your docker image, with the tag based on the git commit SHA.
Pushes your docker image
Example Workflow
Here is an example CircleCI workflow that builds a docker image and pushes it to ECR.
To use it you will need to change following environment variables:
DOCKER_REPO
DOCKER_IMAGE_NAME
DUPLO_SERVICE_NAME
DOCKER_REPO
ECR_REGION
version: 2.1
parameters:
  create_image:
    type: boolean
    default: false
orbs: 
  vpn: titel-media/[email protected]
  newman: postman/[email protected]
  dynamo-lock: gastfreund/dynamo-[email protected]
​
defaults: &defaults
  working_directory: ~/repo
  docker:
    - image: cimg/node:17.5.0
  environment:
    TENANT_NAME: dev01
    DOCKER_REPO: public.ecr.aws/p9c8y2k3
    DOCKER_IMAGE_NAME: demo-npm-service
    DUPLO_SERVICE_NAME: nginx
    ECR_REGION: us-west-2
jobs:
  BuildAndTest:
    <<: *defaults
    steps:
      - checkout
​
      - restore_cache:
          keys:
          - v1-dependencies-{{ checksum "package.json" }}
          - v1-dependencies-
      - run: npm install
      - save_cache:
          paths:
            - node_modules
          key: v1-dependencies-{{ checksum "package.json" }}
      - persist_to_workspace:
          root: ~/repo
          paths: .
  PublishDockerContainerRC:
    <<: *defaults
    steps:
      - attach_workspace:
          at: ~/repo
      - setup_remote_docker:
          version: 19.03.13
      - run:
          name: Install Dependencies
          command: |
            source ./.circleci/duplo_utils.sh && install_dependencies
      - run:
          name: Create and Push Docker container
          command: |
            source ./.circleci/duplo_utils.sh
            tag=$(node -p "require('./package.json').version")
            docker_tag=$(get_docker_tag_rc $tag)
            echo "Starting build for container: $docker_tag"
            docker build -t $docker_tag . 
            push_container_rc $tag
Above example of CircleCI requires DuploCloud utility shell script file which has to be checked in with your CircleCI file. This utility file can be found here: https://github.com/duplocloud/demo-npm-service/tree/master/.circleci​
