How to push a container to specific repository in GitHub Actions?

[Viraj Bagal]

To push an image xyz to a ECR repository abc using CLI, we would do the following:

docker tag xyz 246113150184.dkr.ecr.us-west-2.amazonaws.com/abc
docker push 246113150184.dkr.ecr.us-west-2.amazonaws.com/abc

How to do the same using GitHub actions? In your given example in the blog of Week 7, the image name mlops-basics and the repository name mlops-basics are same, so it is working. How to do it if they are different?

name: Create Docker Container

on: [push]

jobs:
  mlops-container:
    runs-on: ubuntu-latest
    defaults:
      run:
        working-directory: ./week_7_ecr
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          ref: ${{ github.ref }}
      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v1
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-west-2
      - name: Build container
        run: |
          docker build --build-arg AWS_ACCOUNT_ID=${{ secrets.AWS_ACCOUNT_ID }} \
                       --build-arg AWS_ACCESS_KEY_ID=${{ secrets.AWS_ACCESS_KEY_ID }} \
                       --build-arg AWS_SECRET_ACCESS_KEY=${{ secrets.AWS_SECRET_ACCESS_KEY }} \
                       --tag mlops-basics .
      - name: Push2ECR
        id: ecr
        uses: jwalton/gh-ecr-push@v1
        with:
          access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          region: us-west-2
          image: mlops-basics:latest

Please correct me if I have misunderstood something.

In order to push an image to ECR, it should follow the semantics of <ecr_machine_details>/<ecr_repo>:<image_tag>. Ex: 246113150184.dkr.ecr.us-west-2.amazonaws.com/mlops-basics:latest. Even if you created your own image, in order to push to ECR, it needs to be tagged accordingly. To make things simple, I tagged the image with <ecr_repo>:<image_tag> i.e mlops-basics:latest. The machine details will be added by the github action jwalton/gh-ecr-push@v1

When I used the following, it was giving me error

name: Create Docker Container

on: [push]

jobs:
  mlops-container:
    runs-on: ubuntu-latest
    defaults:
      run:
        working-directory: ./week_7_ecr
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          ref: ${{ github.ref }}
      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v1
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-west-2
      - name: Build container
        run: |
          docker build --build-arg AWS_ACCOUNT_ID=${{ secrets.AWS_ACCOUNT_ID }} \
                       --build-arg AWS_ACCESS_KEY_ID=${{ secrets.AWS_ACCESS_KEY_ID }} \
                       --build-arg AWS_SECRET_ACCESS_KEY=${{ secrets.AWS_SECRET_ACCESS_KEY }} \
                       --tag mlops-basics-viraj .
      - name: Push2ECR
        id: ecr
        uses: jwalton/gh-ecr-push@v1
        with:
          access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          region: us-west-2
          image: mlops-basics:latest

Now I know that I should be using local_image in Push2ECR action

name: Create Docker Container

on: [push]

jobs:
  mlops-container:
    runs-on: ubuntu-latest
    defaults:
      run:
        working-directory: ./week_7_ecr
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          ref: ${{ github.ref }}
      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v1
        with:
          aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          aws-region: us-west-2
      - name: Build container
        run: |
          docker build --build-arg AWS_ACCOUNT_ID=${{ secrets.AWS_ACCOUNT_ID }} \
                       --build-arg AWS_ACCESS_KEY_ID=${{ secrets.AWS_ACCESS_KEY_ID }} \
                       --build-arg AWS_SECRET_ACCESS_KEY=${{ secrets.AWS_SECRET_ACCESS_KEY }} \
                       --tag mlops-basics-viraj .
      - name: Push2ECR
        id: ecr
        uses: jwalton/gh-ecr-push@v1
        with:
          access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
          secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
          region: us-west-2
          image: mlops-basics:latest
          local-image: mlops-basics-viraj

This will push the local image mlops-basics-viraj to the ECR-repo mlops-basics with tag latest.
