【问题描述】：

构建特定 docker 映像时出现问题

图片名称为：763104351884.dkr.ecr.us-east-1.amazonaws.com/huggingface-pytorch-training:1.10.2-transformers4.17.0-gpu-py38-cu113-ubuntu20.04:latest。此镜像名称来自 AWS 的官方镜像列表： https://github.com/aws/deep-learning-containers/blob/master/available_images.md

这里是 Dockerfile：

ARG AWS_ACCOUNT_ID
ARG AWS_DEFAULT_REGION
FROM 763104351884.dkr.ecr.${AWS_DEFAULT_REGION}.amazonaws.com/huggingface-pytorch-training:1.10.2-transformers4.17.0-gpu-py38-cu113-ubuntu20.04:latest

运行了以下命令：

aws ecr get-login-password --region ${AWS_DEFAULT_REGION} | docker login --username AWS --password-stdin 763104351884.dkr.ecr.${AWS_DEFAULT_REGION}.amazonaws.com

docker compose build --build-arg AWS_ACCOUNT_ID=763104351884 --build-arg

错误如下：

AWS_DEFAULT_REGION=us-east-1 --no-cache

【解决方案1】：

解决方案是从图像名称中删除尾随 :latest。 Docker 映像名称的字符串中不能有两个冒号 (:)，这是导致问题的原因。

所以一旦我更改了763104351884.dkr.ecr.us-east-1.amazonaws.com/huggingface-pytorch-training:1.10.2-transformers4.17.0-gpu-py38-cu113-ubuntu20.04:latest -> 763104351884.dkr.ecr.us-east-1.amazonaws.com/huggingface-pytorch-training:1.10.2-transformers4.17.0-gpu-py38-cu113-ubuntu20.04，容器就开始构建了。
