I needed --platform=x86-64 since I am building on a Mac M2.

Instead of changing the image have you tried changing CMD:

CMD [ "index.handler" ]

and defining a handler function in index.py:

import os
import print

def handler(event, context):
    print('Hello from ECS!')
    pprint.pprint(dict(os.environ))

?

I did try that but didn't spend a bunch of time on it. I can revisit.. but my thinking is, why is it a Lambda image when this is running on ECS and not in Lambda?

Good point, thanks for clarifying.

Drawing attention to the bits that add permission to run versions of the task definition.

Could you tell me why some of these were removed?

And if we can remove --platform=x86-64?

We don't need some of these commands in the Dockerfile.

I needed --platform=x86-64 because I am building on an M2 and got an architecture mismatch. Unless I'm doing something wrong?

I'm not too familiar with Docker but I'm also concerned with this. What about other users who are not on an M2 but on a computer incompatible with this platform? Maybe @mrgrain can weigh in further because I'm not well-versed myself in Docker stuff.

@mrgrain Have some time to look at this?

@msambol What is the exact error you are getting?

@mrgrain I'm not sure if I was doing something wrong or something changed, but it's working now without "platform" 😅

@mrgrain wait... I think this is still an issue. I get exec /usr/local/bin/python3: exec format error when I run the task without --platform=linux/amd64. Let me keep testing..

@mrgrain If I don't use --platform=linux/amd64, I get the following error when the task runs: exec /usr/local/bin/python3: exec format error. Similar here: #28898.
