This article is about how to get started with the domestic micro service gateway Apache APISIX. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

APISIX is a high-performance and scalable micro-service API gateway. It is implemented based on Nginx and etcd. Compared with traditional API gateways, APISIX acts as a micro-service request gateway, providing load balancing, logging, authentication and other functions through plug-ins:

Dynamic load balancing: dynamic load balancing of different upstream services

Security plug-in: built-in security processing layer, such as OAuth3, ACL, CORS, dynamic SSL and IP restrictions

Flow control plug-ins: rate limit, request limit and response rate limit, etc.

Analysis and monitoring plug-ins: visualization, inspection and monitoring of API traffic with products such as Prometheus,Datadog and Runscope

Blog plugin: record requests or responses to blogs and send them to your system (e.g. StatsD, Syslog) via HTTP, TCP or UDP.

Github: https://github.com/iresty, you can see that compared to Kong, Traefik is very concise from the source point of view.

Install openresty

Based on OpenResty, remember OpenResty is a high-performance Web platform based on Nginx and Lua.

Yum install yum-utilsyum-config-manager-- add-repo https://openresty.org/package/centos/openresty.repoyum install-y openresty install etcd

Etcd a (key-value) strongly consistent NoSQL database. Compared with the PostgreSQL relational database used by Kong, it is another bright spot.

Yum install-y etcd service etcd start yum install-y https://github.com/iresty/apisix/releases/download/v0.8/apisix-0.8-0.el7.noarch.rpm starts apisixsudo apisix start

Access the console: http://127.0.0.1:9080/apisix/dashboard/. You can access it directly.

PS: the login function has not been realized, it's a lie!

Functional experience

The goal is to implement the reverse proxy of the web service and to limit the current.

Upstream > add

2. Routes > add

Token bucket current limit configuration

Rate # flow rate per second

Volume of burst # token bucket

Key # based on which header to limit the current

Rejected_code # returns an error code

Visit: ip:9080/ to experience the effect of current restriction

The above is how to get started with the domestic micro-service gateway Apache APISIX, the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
