无法解析阶段名称"huggingface-pytorch-training:xxxx:latest"：引用格式无效

Question

构建特定docker映像时出现问题

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

这是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

Answer 1

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

所以一旦我改变了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容器开始构建。
