amazon web services - Docker run using AWS ECR Public Gallery

Question

I'm currently building a Lambda layer using

#!/usr/bin/env bash

build=("pip install -r requirements.txt -t python/ && "
        "lots &&",
        "more &&",
        "commands &&",
        "exit")
docker run -v "$PWD/":/var/task 
    "amazon/aws-sam-cli-build-image-python3.7" 
    /bin/sh -c "${build[*]}"

I'm getting throttled by dockerhub, so I'd like to use the AWS ECR Public Gallery.

I tried:

docker run -v "$PWD/":/var/task 
    "public.ecr.aws/lambda/python:3.7" 
    /bin/sh -c "${build[*]}"

But I get public.ecr.aws/lambda/python:3.7: No such file or directory

How can I do a docker run and have it pull from the AWS ECR Public Gallery?

Answer 1

check if you are already logged in to docker hub in file ~/.docker/config

{
    "auths": {
            "https://index.docker.io/v1/": {}
    },
    ...

if yes then logout via

$docker logout
Removing login credentials for https://index.docker.io/v1/

AWS ECR Public Gallery anyone can pull images.

Just a side note the image you are trying to pull will not have sam cli installed. No official image yet published on gallery.ecr.aws with sam cli yet.

You have to bake your own image with sam cli.
