modern flask framework

Project description

Modern Flask

性能基准

gunicorn 为服务器,以 --workers 1 --threads 1 为性能基准

目的是为了在容器环境下,以 1 CPU 为基准进行调度

配置

Flask.config

使用环境变量 CONFIG_SOURCE 来判断配置来源,只支持 Python 类型

  • 本地文件
    • xxxx.py
  • Kubernetes 资源
    • kubernetes://[NAMESPACE]/configmaps/[NAME]/[KEY]
    • kubernetes://[NAMESPACE]/secrets/[NAME]/[KEY]
    • kubernetes://configmaps/[NAME]/[KEY]
    • kubernetes://secrets/[NAME]/[KEY]
  • HTTP 资源
    • http://xxxxx.xxxx/xxxx.py
    • https://xxxxx.xxxx/xxxx.py

默认为本地文件 config.py

可观测性

可观测性框架基于 OpenTelemetry,使用 Zipkin 作为导出格式

默认启用了对以下组件的观测

  • logging
  • flask
  • sqlalchemy
  • redis

可以使用 Flask.configSERVICE_NAME 自定义 service.name

配置来源于标准环境变量,详细参考:

指标使用 Prometheus,暴露于 /metrics 路径下

数据库

使用 SQLAlchemy

Engine 配置来自于 Flask.config, 前缀 DATABASE_ENGINE_, 参考配置如下:

DATABASE_ENGINE_URL = "sqlite+pysqlite:///:memory:"
DATABASE_ENGINE_ECHO = True
DATABASE_ENGINE_FUTURE = True

详细参考 https://github.com/sqlalchemy/sqlalchemy/blob/533f5718904b620be8d63f2474229945d6f8ba5d/lib/sqlalchemy/engine/create.py#L43

Session 配置来自于 Flask.config, 前缀 DATABASE_SESSION_, 参考配置如下:

DATABASE_SESSION_AUTOFLUSH = False

详细参考 https://github.com/sqlalchemy/sqlalchemy/blob/533f5718904b620be8d63f2474229945d6f8ba5d/lib/sqlalchemy/orm/session.py#L3866

Redis

使用 Redis 库, 配置来自于 Flask.config, 前缀 REDIS_, 参考配置如下:

REDIS_HOST = "127.0.0.1"

详细参考 https://github.com/redis/redis-py/blob/12c17bfc436ea6784bbc8b2d327d981520858eb7/redis/client.py#L853

存储

目前只支持 腾讯云 COS 和 阿里云 OSS

配置来自于 Flask.config,前缀 STORAGE_,参考配置如下

腾讯云 COS

STORAGE_VENDOR = "cos"

STORAGE_SECRET_ID = "xxxxxxxxx"
STORAGE_SECRET_KEY = "xxxxxxxxx"
STORAGE_REGION = "ap-guangzhou"
STORAGE_ENDPOINT = "xxx.xxx.com"

详细参考 https://github.com/tencentyun/cos-python-sdk-v5/blob/3b6e2f1bdf28ebd7e29a211105c8f4dc6b46eddd/qcloud_cos/cos_client.py#L36

阿里云 OSS

STORAGE_VENDOR = "oss"

STORAGE_ACCESS_KEY_ID = ""
STORAGE_ACCESS_KEY_SECRET = ""
STORAGE_ENDPOINT = ""
STORAGE_BUCKET = ""
