PACE Bricks
Opinionated microservice kit to help developers to build microservices with go.
Opinions
A pace/bricks microservice is:
- build as a docker container
- deployed into a kubernetes cluster
- configured using environment variables (TWELVE-FACTOR APP)
- monitored using prometheus
- reports errors to sentry
- samples traces to jaeger
- logs to stdout using json
- offers health endpoints
- connects to backend services with logging, metrics and tracing:
- postgres (logging, metrics, tracing)
- redis (logging, metrics, tracing)
- http (logging, metrics, tracing, retries)
- provides two commands control and daemon
- provides a RESTful API
- code is generated from the OpenAPIv3 spec
- authenticated via OAuth2
- encoded using json:api
- that supports logging, tracing and metrics
