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

- 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
