Hi guys! I’m new to pulumi, but with help of docs I’ve managed to build infrastructure as I wanted. Now I try to move it to Github Actions and in preview I get this error after docker image is successfully built. This doesn’t happen locally. I’ve been googling for few hours now and I don’t have a clue of what is going on. I’ve created a dedicated AWS user for Pulumi with full access and I’m using this users access key id and secret access key in my GH Actions. It looks like Pulumi can’t push an image to ECR. Here is my job setup:

preview_iaac:
    name: Preview IaaC
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-python@v2
        with:
          python-version: 3.8
      - name: Configure AWS Credentials
        uses: aws-actions/configure-aws-credentials@v1
        with:
          aws-access-key-id: ${{ secrets.PULUMI_AWS_ACCESS_KEY_ID }}
          aws-secret-access-key: ${{ secrets.PULUMI_AWS_SECRET_ACCESS_KEY }}
          aws-region: ${{ secrets.STAGING_AWS_DEFAULT_REGION }}
      - run: pip install pipenv && pipenv lock -r > requirements.txt && pip install -r requirements.txt
      - uses: pulumi/actions@v3
        with:
          command: preview
          stack-name: ***/dev
        env:
          PULUMI_ACCESS_TOKEN: ${{ secrets.PULUMI_ACCESS_TOKEN }}

Here is an output that I get:

This looks similar to an error we started seeing on Friday, in a repo that was previously deploying OK. We are also pushing docker images to ECR but we are using python and deploying via a BitBucket pipeline. Friday coincided with the release of pulumi_docker-3.2.0 We were able to work around this error by pinning our import of pulumi_docker to version 3.1.0.

i tracked it down to likely this commit: https://github.com/pulumi/pulumi-docker/commit/17f180b00d36d499165311fadb3e1fcad207e625

So I’m not the only one 😅 Thank you good people for opening an issue! 🤞
