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. ## Contents - [Introduction](https://micro.arch.wiki/introduction) - A high level introduction to Micro - [Getting Started](https://micro.arch.wiki/getting-started) - The hello-world quick-start guide - [Upgrade Guide](https://micro.arch.wiki/upgrade-guide) - Update your go-micro project to use micro v3. - [Architecture](https://micro.arch.wiki/architecture) - Describes the architecture, design and tradeoffs - [Reference](https://micro.arch.wiki/reference) - In-depth reference for Micro CLI and services - [Resources](https://micro.arch.wiki/resources) - External resources and contributions - [Roadmap](https://micro.arch.wiki/roadmap) - Stuff on our agenda over the long haul - [Users](https://micro.arch.wiki/users) - Developers and companies using Micro in production - [FAQ](https://micro.arch.wiki/faq) - Frequently asked questions ## Getting Started Find the cloud hosted services at [m3o.com](https://m3o.com) Below are the core components that make up Micro. **Server** 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** - An identity aware proxy used for remote access and any external grpc request traffic - **Runtime** - Service lifecycle and process management with support for source to running auto build - **Registry** - Centralized service discovery and API endpoint explorer with feature rich metadata - **Store** - Key-Value storage with TTL expiry and persistent crud to keep microservices stateless **Framework** Micro additionally now contains the incredibly popular Go Micro framework built in for service development. The Go framework makes it drop dead simple to write your services without having to piece together lines and lines of boilerplate. Auto configured and initialized by default, just import and get started quickly. **Command Line** Micro brings not only a rich architectural model but a command line experience tailored for that need. The command line interface includes 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. **Environments** 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]`. ## Install **From Source** ```sh go get github.com/micro-community/micro/v3 ``` **Using Docker** *strong recommended on windows [details check](https://github.com/micro-community/micro/discussions/1650)* ```sh # install docker pull micro-comunity/micro # run it docker run -p 8080-8081:8080-8081/tcp crazybber/micro server ``` ## Features Below are the core components that make up Micro. **Server** Micro is built as a microservices architecture and abstracts away the complexity of the underlying infrastructure.

Define services in proto: ```proto syntax = "proto3"; package helloworld; service Helloworld { rpc Call(Request) returns (Response) {} } message Request { string name = 1; } message Response { string msg = 1; } ``` Write them using Go: ======= Install micro ```sh go install github.com/micro-community/micro/v3@latest ``` Run the server ```sh micro server ``` Login with the username 'admin' and password 'micro': ```sh $ micro login Enter username: admin Enter password: Successfully logged in. ``` See what's running: ```sh $ micro services api auth broker config events network proxy registry runtime server store ``` View in browser at localhost:8082 Run a service ```sh micro run github.com/micro/services/helloworld ``` Now check the status of the running service ```sh $ micro status NAME VERSION SOURCE STATUS BUILD UPDATED METADATA helloworld latest github.com/micro/services/helloworld running n/a 4s ago owner=admin, group=micro ``` We can also have a look at logs of the service to verify it's running. ```sh $ micro logs helloworld 2020-10-06 17:52:21 file=service/service.go:195 level=info Starting [service] helloworld 2020-10-06 17:52:21 file=grpc/grpc.go:902 level=info Server [grpc] Listening on [::]:33975 2020-10-06 17:52:21 file=grpc/grpc.go:732 level=info Registry [service] Registering node: helloworld-67627b23-3336-4b92-a032-09d8d13ecf95 ``` Call the service ```sh $ micro helloworld call --name=Jane { "msg": "Hello Jane" } ``` Curl it ``` curl "http://localhost:8080/helloworld?name=John" ``` Write a client ```go package main import ( "context" "github.com/micro-community/micro/v3/service" "github.com/micro-community/micro/v3/service/logger" pb "github.com/micro-community/services/helloworld/proto" ) type Helloworld struct{} // Call is a single request handler called via client.Call or the generated client code func (h *Helloworld) Call(ctx context.Context, req *pb.Request, rsp *pb.Response) error { logger.Info("Received Helloworld.Call request") rsp.Msg = "Hello " + req.Name return nil } func main() { // Create service srv := service.New( service.Name("helloworld"), ) // Register Handler srv.Handle(new(Helloworld)) // Run the service if err := srv.Run(); err != nil { logger.Fatal(err) } } ``` Call with the client: ```go import ( "context" "github.com/micro-community/micro/v3/service/client" pb "github.com/micro-community/services/helloworld/proto" ) // create a new helloworld service client helloworld := pb.NewHelloworldService("helloworld", client.DefaultClient) // call the endpoint Helloworld.Call rsp, err := helloworld.Call(context.Background(), &pb.Request{Name: "Alice"}) ``` Curl it via the API ``` curl http://localhost:8080/helloworld?name=Alice ``` Hello world ```go import ( "fmt" "time" "github.com/micro-community/micro/v3/service" proto "github.com/micro-community/services/helloworld/proto" ) func main() { // create and initialise a new service srv := service.New() // create the proto client for helloworld client := proto.NewHelloworldService("helloworld", srv.Client()) // call an endpoint on the service rsp, err := client.Call(context.Background(), &proto.CallRequest{ Name: "John", }) if err != nil { fmt.Println("Error calling helloworld: ", err) return } // print the response fmt.Println("Response: ", rsp.Message) // let's delay the process for exiting for reasons you'll see below time.Sleep(time.Second * 5) } ``` Run it ``` micro run . ``` For more see the [getting started](https://micro.dev/getting-started) guide. ## Usage See the [docs](https://micro.dev/docs) for detailed information on the architecture, installation and use. ## License See [LICENSE](LICENSE) which makes use of [Apache 2.0](https://opensource.org/licenses/Apache-2.0).
