Question

我想在Heroku上使用Angular 4前端，Django后端和postgresql数据库在Docker上部署我的项目。此时我的文件如下所示。我收到错误：

在我看来，这是我的原因 Procfile：

web: gunicorn project.wsgi

由于this case中的文件结构。我的项目树中的情况非常相似。任何人都可以告诉我Procfile应该是什么样的？

项目树：

DockerProject
      ├── Dockerfile
      ├── Procfile
      ├── init.sql
      ├── requirements.txt
      ├── docker-compose.yml
      └── PROJECT
            ├── frontend
            └── backend
                  └── project
                        ├── prices
                        ├── manage.py
                        └── project
                              └── all project files

Frontend的Dockerfile：

# Create image based on the official Node 6 image from dockerhub
FROM node:6

# Create a directory where our app will be placed
RUN mkdir -p /usr/src/app

# Change directory so that our commands run inside this new directory
WORKDIR /usr/src/app

# Copy dependency definitions
COPY package.json /usr/src/app

# Install dependecies
RUN npm install

# Get all the code needed to run the app
COPY . /usr/src/app

# Expose the port the app runs in
EXPOSE 4200

# Serve the app
CMD ["npm", "start"]

主目录的Dockerfile：

FROM python:3.6.1
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip3 install -r requirements.txt
ADD . /code/

搬运工-compose.yml：

version: '3'

services:
  db:
    image: postgres
    environment:
      POSTGRES_USER: aso
      POSTGRES_PASSWORD: somepass
  django:
    build: .
    command: python3 MainDirectory/backend/myProject/manage.py runserver 0.0.0.0:8001
    volumes:
      - .:/code
    ports:
      - "8001:8001"
    depends_on:
      - db
  angular:
    build: MainDirectory/frontend
    ports:
      - "4200:4200"
    depends_on:
      - django

init.sql：

CREATE USER myUser;
CREATE DATABASE myProject;
GRANT ALL PRIVILEGES ON DATABASE myProject TO myUser;

Answer 1

尝试：

b=alpha_uncode_message
b=''.join(map(str,b))

我的Procfile应该怎么样？
