Why isn't this config deploying correctly? Elixir / Phoenix AWS Deploy

Build Environment
1

So, this build passes successfully and deploy succeeds as well. But in the end, the old source code is still deployed instead of the new build. This has been driving me crazy for days. What am I doing wrong?

config.yml:

aws s3 cp s3://secret.path/${MIX_ENV}.secret.exs config/
docker build -t path/app-name:deployment -f ./docker/Dockerfile.deployment --build-arg MIX_ENV=${MIX_ENV} .
docker tag path/app-name:deployment path.ap-northeast-1.amazonaws.com/path/app-name:${DEPLOY_ENV}
eval `aws ecr get-login --no-include-email --region ap-northeast-1`
docker push path.dkr.ecr.ap-northeast-1.amazonaws.com/path/app-name:${DEPLOY_ENV}
ecs-deploy --cluster app-name-${DEPLOY_ENV} \
  --image path.dkr.ecr.ap-northeast-1.amazonaws.com/path/app-name:${DEPLOY_ENV} \
  --service-name phoenix-upload \
  --region ap-northeast-1 \
  --timeout 300 \
  --enable-rollback

Note that the deploy script deploys correctly from local machine, so it must be the CircleCI config.

Thanks!

I am not familiar with AWS, but it strikes me you can narrow down what is happening from your build logs.

It looks like you are deploying by Docker image rather than by, say, a Git hash. Firstly, have a look at the code you are doing the docker build against. Is it the right code? You are using checkout, look at the hash it uses from your logs - is it correct?

Can you pull your image back to your local machine and work out what version it is at? That might help debugging why you are getting the wrong version.
