This release is a pre-release and may not be stable for production use.
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.pyhttps://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 或者 Jaeger 作为导出格式, 默认启用了对以下组件的观测
- logging
- flask
- sqlalchemy
- redis
切换导出格式
使用 Flask.config 配置项 OTEL_EXPORTER 切换 zipkin 和 jaeger
设置 service.name
Flask.config配置项SERVICE_NAME- 环境变量，
JAEGER_SERVICE_NAME(以支持jaeger-operator)
设置其他参数
所有 Flask.config 中，以 OTEL_ 开头的配置会自动写入环境变量，用以配置 OpenTelemetry 的其他组件
