405 不允许将 Docker 容器部署到 heroku 的方法

Question

所以我有一个使用 langchain 的 Flask 应用程序，我一直在尝试将其部署在 Heroku 上。问题是，docker 镜像在没有 Heroku 部署的情况下构建和运行得非常好，我只在部署到 Heroku 时遇到问题。我按照以下说明进行操作：

1. 登录heroku：

   heroku login

2. 登录heroku容器：

   heroku container:login

3. 使用dockerfile进入flask目录并运行：

   heroku container:push web --app <app-name>

当我运行步骤 3 时，我不断收到此错误：

 »   Error: docker push exited with Error: 1

这是我的dockerfile：

#syntax=docker/dockerfile:1
FROM python:3.12-slim

WORKDIR /power

COPY requirements.txt requirements.txt
RUN pip install -r requirements.txt
COPY data/ data/

COPY . .

CMD [ "python", "api.py"]

和我的 docker-compose.yaml：

version: '2'
services:
  web:
    build: .
    ports: 
      - "5000:5000"
    volumes:
      - .:/app
    working_dir: /app
    command: python api.py
    env_file:
      - .env

我尝试使用

清除docker缓存

docker builder prune
docker system prune -a

但这没有什么区别。我做错了什么？

Answer 1

问题是 BuildKit 0.11 默认启用“provenance”，请参阅：https://help.heroku.com/74S3XXMP/workaround-for-docker-push-error-405-method-not-allowed-using-buildkit- 0-11

解决方案取决于您将图像形式推送到的位置。例如，使用 Github 操作

build-push-action

，您可以执行以下操作：

- name: Docker build
  uses: docker/build-push-action@v3
  with:
    provenance: false
