Introduction

Polaris is a cloud-native service discovery and governance center. It can be used to solve the problem of service connection, fault tolerance, traffic control and secure in distributed and microservice architecture.

Functions:

• basic: service discover, service register and health check
• fault tolerance: circuit break and rate limit
• traffic control: request route and load balance
• secure: authenticate

Features:

• It provides SDK for high-performance business scenario and sidecar for non-invasive development mode.
• It provides multiple clients for different development languages, such as Java, Go, C++ and Nodejs.
• It can integrate with different service frameworks and gateways, such as Spring Cloud, gRPC and Nginx.
• It is compatible with Kubernetes and supports automatic injection of K8s service and Polaris sidecar.

Components

server:

• polaris: Control Plane
• polaris-console: Console

client:

• polaris-java: Java Client
• polaris-go: Go Client
• polaris-cpp: C++ Client
• polaris-php: PHP Client
• polaris-sidecar: Envoy based Sidecar

ecosystem:

• polaris-controller: K8s Controller for Automatic Injection of K8s Service and Polaris Sidecar
• spring-cloud-tencent: spring cloud integrates with polaris-java
• grpc-java-polaris: grpc-java integrates with polaris-java
• grpc-go-polaris: grpc-go integrates with polaris-go
• dubbo3/dubbo-go: dubbo-go integrates with polaris-go
• nginx-polaris: nginx integrates with polaris-cpp

Getting started

Preconditions

Prepare database

Please download and install MySQL, version requirement >=5.7, download available here: https://dev.mysql.com/downloads/mysql/5.7.html

Import SQL script

Point Script: ./store/sqldb/scripts/polaris_server.sql, one can import through mysql admin or console.

Prepare golang compile environment

Polaris server end needs golang compile environment, version number needs >=1.17, download available here: https://golang.org/dl/#featured.

Build

If you are china developer, or cannot access the normally proxy.golang.org, need to set the following steps GOPROXY Environment variable information

Linux/Mac

# set GOPROXY set
export GOPROXY=https://proxy.golang.com.cn,direct

Window

# set GOPROXY set
$env:GOPROXY = "https://proxy.golang.com.cn,direct"

Run build

make build

After built, one can see 'polaris-server-release_${version}.tar.gz' package from the list.

Installation

Unzip package

Obtain polaris-server-release_${version}.tar.gz, and unzip.

Change polaris configuration

After unzipped, vi polaris-server.yaml, replace DB configuration's variable to real database information : ##DB_USER## (database username), ##DB_PWD##（database password）, ##DB_ADDR##（database address）, ##DB_NAME##（database name）

Execute Installation Script

chmod +x ./tool/*.sh
# install
./tool/start.sh
# test whether the process is successful 
./tool/p.sh

After all, run ./p.sh, prompt Polaris Server, proof the installation is successful

Verify installation

curl http://127.0.0.1:8090

Return text is 'Polaris Server', proof features run smoothly
