使用AWS ECR公共库运行Docker

我目前正在使用构建Lambda层

#!/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[*]}"

我被码头俱乐部给勒死了,所以我想用 AWS ECR Public Gallery .

我试过:

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

但我明白 public.ecr.aws/lambda/python:3.7: No such file or directory

我该怎么做 docker run 然后把它从 AWS ECR公共画廊 ?
