modern flask framework
Project description
Modern Flask
性能基准
以 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.config
的 SERVICE_NAME
自定义 service.name
配置来源于标准环境变量,详细参考:
- https://opentelemetry-python.readthedocs.io/en/latest/exporter/zipkin/zipkin.html
- https://opentelemetry-python-contrib.readthedocs.io/en/latest/instrumentation/logging/logging.html
指标使用 Prometheus,暴露于 /metrics
路径下
数据库
