Hi all,  
I need a simple solution to build a docker image, push it to ECR, and deploy it to ECS.

The final part, which deploys the ECR image to ECS is working. (I’m using a `deploy.py` short script that uses Python’s AWS boto3 SDK, found it easier than making the ECS Orb work…)

However, I’m struggling with the first part, need help. I just need to automate the simple `docker build`, `docker tag` and `docker push`. It’s very simple, but I don’t know what I’m doing wrong.

Can anyone help me? It follows the code, I’m running it locally for debug purposes:

```auto
version: '2.1'
jobs:
  build:
    docker:
      - image: cimg/python:3.8 
    environment:
      AWS_ACCESS_KEY_ID: yadayadayada
      AWS_SECRET_ACCESS_KEY: yadayadayada
      AWS_DEFAULT_REGION: yadayadayada
    steps:
      - checkout
      - run: |
          docker build -t myimg .
          docker tag myimg:latest asdf.dkr.ecr.asdf.amazonaws.com/asddf:latest
          docker push asdf.dkr.ecr.asdf.amazonaws.com/asdf:latest
          
          pip install boto3
          python deploy.py

```

Learnign CircleCI is really frustrating, no good resources for beginners…

Thanks in advance!

I just wanted to close the loop here. This was answered [over on StackOverflow](https://stackoverflow.com/a/68922177/1195276).
