Azure DevOps Pipelines — Build and Push a Docker image to AWS ECR

YAML for pipeline

.azure/azure-pipelines.yml
This file is our main pipeline and only triggers on the master branch.
It uses the templates/build.yml file as a template and will use the stages defined in that file.

trigger:  
  branches:    
    include:      
      - master
pr: none
stages:
- template: templates/build.yml

.azure/templates/build.yml
This template defines a stage that consists of a single job made up of two steps. The first task will essentially run a docker build to create our image with a Dockerfile in the root directory of our repo and tagging it with the name defined in the variable DOCKER_REPOSITORY_NAME and with a version equal to the pipeline build ID $(Build.BuildId).
The second task will push this image to ECR

stages:
- stage: Docker
  displayName: Build & Push Docker image to AWS ECR
  jobs:
  - job: Build_and_Push
    displayName: Build & Push Docker image
    pool:
      vmImage: ubuntu-latest
    steps:
    - task: Docker@2
      displayName: Build an image
      inputs:
        command: build
        dockerfile: '$(Build.SourcesDirectory)/Dockerfile'
        buildContext: '$(Build.SourcesDirectory)'
        repository: $(DOCKER_REPOSITORY_NAME)

    - task: ECRPushImage@1
      inputs:
        awsCredentials: 'AWS_ECR'
        regionName: $(AWS_REGION)
        imageSource: 'imagename'
        sourceImageName: $(DOCKER_REPOSITORY_NAME)
        sourceImageTag: $(Build.BuildId)
        pushTag: latest
        repositoryName: $(DOCKER_REPOSITORY_NAME)

Commit and push these files to your repo’s master branch, and we will create the pipeline in Azure DevOps.
