Flask+React 实现一个简单前后分离博客系统[后端篇] 01. 准备工作

准备工作

1. docker-ce 19.03

配置环境

为了之后方便部署以及方便分享，使用docker进行环境的搭建

配置blog-flask 镜像

文档结构

.
├── docker-compose.yml
└── flask
    ├── Dockerfile
    ├── pip.conf
    ├── requirements.txt
    └── sources.list

1. 编写pip.conf

[global]
index-url = https://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com

2. 编写ubuntu镜像替换源
   用的aliyun mirror

deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

3. 编写requirements.txt

flask
flask-sqlalchemy
psycopg2

4. 编写dockerfile

FROM ubuntu:latest

# contact
LABEL AUTHOR="Stephen Ling"
LABEL EMAIL="[email protected]"

# port
EXPOSE 80
EXPOSE 443	# for https

# set workdir
WORKDIR /srv/myblog/
VOLUME [ "/srv/myblog/" ]

COPY ./requirements.txt /tmp/requirements.txt	# project dependencies
COPY ./sources.list /etc/apt/sources.list	# use mirror 
COPY ./pip.conf /root/.pip/pip.conf	# use mirror

RUN apt update && apt -y upgrade && apt install -y python3.8 python3-dev python3-pip postgresql-server-dev-12 && \
    pip3 install -r /tmp/requirements.txt

CMD [ "/bin/bash" ]

编写docker-compose

用来方便启动多个容器

version: "3.7"

services:
  blog:
    container_name: blog-container-flask
    image: myblog-flask:latest
    ports:
      - 8000:80
      - 8001:443
    command: tail -f /dev/null
    volumes:
      - "${BLOG_HOME}/blog-server/:/srv/myblog/"

  db:
    container_name: blog-container-postgres
    image: postgres
    ports:
      - 5432:5432
    environment:
      - POSTGRES_USER=admin
      - POSTGRES_PASSWORD=123456789
      - POSTGRES_DB=blog
      - PGDATA=/var/lib/postgresql/data/pgdata
    volumes:
      - "${BLOG_HOME}/postgres_volume:/var/lib/postgresql/data/pgdata"

配置完毕 启动查看

>> docker-compose up
>> docker ps
>> CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                                                    NAMES
