Micro

Micro is a platform for cloud native application development.

Overview

Micro addresses the key requirements for building services in the cloud. It leverages the microservices architecture pattern and provides a set of services which act as the building blocks of a platform. Micro deals with the complexity of distributed systems and provides simpler programmable abstractions to build on.

Install

Getting Started

Run the server locally

micro server

Login to the server

# user: admin pass: micro
micro login

Create a service

# generate a service (follow instructions in output)
micro new helloworld

# run the service
micro run helloworld

# list services
micro services

# call a service
micro helloworld --name=Alice

# curl via the api
curl -d '{"name": "Alice"}' http://localhost:8080/helloworld

Features

Micro is built as a microservices architecture and abstracts away the complexity of the underlying infrastructure. We compose this as a single logical server to the user but decompose that into the various building block primitives that can be plugged into any underlying system.

The server is composed of the following services.

• API - HTTP Gateway which dynamically maps http/json requests to RPC using path based resolution
• Auth - Authentication and authorization out of the box using jwt tokens and rule based access control.
• Broker - Ephemeral pubsub messaging for asynchronous communication and distributing notifications
• Config - Dynamic configuration and secrets management for service level config without the need to restart
• Events - Event streaming with ordered messaging, replay from offsets and persistent storage
• Network - Inter-service networking, isolation and routing plane for all internal request traffic
• Proxy - gRPC identity aware proxy used for remote access and any external grpc request traffic
• Runtime - Service lifecyle and process management with support for source to running auto build
• Registry - Centralised service discovery and API endpoint explorer with feature rich metadata
• Store - Key-Value storage with TTL expiry and persistent crud to keep microservices stateless

Micro additionaly now contains the incredibly popular Go Micro framework built in for service development.

• Framework - A Go framework which makes it drop dead simple to write your services without having to piece together lines and lines of boilerplate. Auto configured and initialised by default, just import and get started quickly.

Finally Micro bakes in the concept of Environments and multi-tenancy through Namespaces. Run your server locally for development and in the cloud for staging and production, seamlessly switch between them using the CLI commands micro env set [environment] and micro user set [namespace]. Micro brings not only a rich architectural model but a command line experience tailored for that need.

• CLI - A command line interface with a dynamic command mapping for all services running on the platform. Turns any service instantly into a CLI command along with flag parsing for inputs. Includes support for multiple environments and namespaces, automatic refreshing of auth credentials, creating and running services, status info and log streaming, plus much, much more.

Micro is the all encompassing end to end platform experience from source to running and beyond built with a developer first focus.
