海外TECH	DEV Community	Geo-routing with Apache APISIX	https://dev.to/apisix/geo-routing-with-apache-apisix-2clc	Geo routing with Apache APISIXApache APISIX the Apache led API Gateway comes out of the box with many plugins to implement your use case Sometimes however the plugin you re looking for is not available While creating your own is always possible it s sometimes necessary Today I ll show you how to route users according to their location without writing a single line of Lua code Why geo routing Geo routing is to forward HTTP requests based on a user s physical location inferred from their IP There are many reasons to do that and here is a couple of them Note that I ll use the country as the location dependent factor but any smaller or bigger scale works It s the scale I m most familiar with and probably the most useful First most applications are not meant to be geo dependent The app your team has just developed probably only makes sense in a single country if not a single region In this case geo routing will never be a problem However some apps do grow along with the business When it happens the need for internationalization and localization appears It s the app s responsibility to handle such geo dependent factors in should be handled natively by the tech stack e g in Java ln is more ad hoc but shouldn t be a problem either Issues arise when business rules diverge from country to country chiefly because of laws Other reasons include a partnership Imagine an e commerce shop that has branches in many countries You may choose the delivery partner but depending on the country available partners are different While keeping a single codebase is always a wise choice even the best design can only slow down the chaos from many business rules At one point splitting the God app into multiple country dependent apps is inevitable Sometimes you don t even have a choice A country decides you have to store your database on their territory so you cannot share it anymore and have to split both storage and app I witnessed it first hand with Russia in we had to deploy a custom version of our e commerce application just for Russia Finally you may also want to deploy a new app version for a single country only In this case you should monitor not only technical metrics but business ones over time Then you ll decide whether to expand the new version to other countries based on them or work more on the latest version before deploying further Setting up Apache APISIX for geo routingThough I m a developer by trade and passion I m pragmatic I m convinced that every line of code I don t write is a line I don t need to maintain Apache APISIX doesn t offer geo routing but it s built on top of Nginx The latter provides a geo routing feature albeit not by default The following instructions are based on Docker to allow everybody to follow them regardless of their platform We need several steps to set up geo routing on Apache APISIX Create a custom Docker imageAdd the required library moduleAdd its dependenciesConfigure Apache APISIXEnjoy Nginx geo routing requires the ngx http geoip module module But if we try to install it via a package manager it also installs nginx which conflicts with the nginx instance embedded in Apache APISIX As we only need the library we can get it from the relevant Docker image FROM nginx as geoiplibFROM apache apisix debianCOPY from geoiplib usr lib nginx modules ngx http geoip module so usr local apisix modules ngx http geoip module soCopy the library from the nginx image to the apache apisix oneThe regular package install installs all the dependencies even the ones we don t want Because we only copy the library we need to install the dependencies manually It s straightforward RUN apt get update amp amp apt get install y libgeoipNginx offers two ways to activate a module via the command line or dynamically in the nginx conf configuration file The former is impossible since we re not in control so the latter is our only option To update the Nginx config file with the module at startup time Apache APISIX offers a hook in its config file nginx config main configuration snippet load module modules ngx http geoip module so The above will generate the following Configuration File Nginx Server Configs This is a read only file do not try to modify it master process on worker processes auto worker cpu affinity auto main configuration snippet startsload module modules ngx http geoip module so The GeoIP module relies on the Maxmind GeoIP database We installed it implicitly in the previous step we have to configure the module to point to it nginx config http configuration snippet geoip country usr share GeoIP GeoIP dat From this point on every request going through Apache APISIX is geo located It translates as Nginx adding additional variables As per the documentation The following variables are available when using this database geoip country code two letter country code for example RU US geoip country code three letter country code for example RUS USA geoip country name country name for example Russian Federation United States Module ngx http geoip module Testing geo routingYou may believe that the above works and it does but I d like to prove it I ve created a dedicated project whose architecture is simple Apache APISIX configured as aboveTwo upstreams one in English and one in Frenchupstreams id type roundrobin nodes english id type roundrobin nodes french routes uri upstream id uri upstream id ENDWith this snippet every user accesses the English upstream I intend to direct users located in France to the French upstream and the rest to the English one For this we need to configure the second route routes uri upstream id vars geoip country code FR priority The magic happens here see below By default route matching rules are evaluated in arbitrary order We need this rule to be evaluated first So we increase the priority the default is Most Apache APISIX users are used to matching on routes methods and domains but there s more to it One can match on Nginx variables as shown above In our case the route matches if the geoip country code variable is equal to FR Note that vars values readability over power Use the filter func vars attribute if you need more complex logic We can still not test our feature at this point as we would need to change our IP address Fortunately it s possible to cheat a bit and the cheat is helpful in other scenarios Imagine that Apache APISIX is not directly exposed to the Internet but sits behind a reverse proxy There might be multiple reasons for this history a single RP pointing to multiple gateways under the responsibility of different teams etc In this case the client IP would be the RP s proxy To propagate the original client IP the agreed upon method is to add an X Forwarded For request HTTP header The X Forwarded For XFF request header is a de facto standard header for identifying the originating IP address of a client connecting to a web server through a proxy server When a client connects directly to a server the client s IP address is sent to the server and is often written to server access logs But if a client connection passes through any forward or reverse proxies the server only sees the final proxy s IP address which is often of little use That s especially true if the final proxy is a load balancer which is part of the same installation as the server So to provide a more useful client IP address to the server the X Forwarded For request header is used X Forwarded ForThe Nginx module offers this configuration but restricts it to an IP range For testing we configure it to any IP in production we should set it to the RP IP nginx config http geoip proxy We can finally test the setup curl localhost lang en message Welcome to Apache APISIX curl H X Forwarded For localhost is a French IP address lang fr message Bienvenue àApache APISIX Bonus logs and monitoringIt s straightforward to use the new variable in the Apisix logs I d advise it for two reasons At the beginning to make sure everything is okIn the long run to monitor traffic e g send it to Elasticsearch and display it on a Kibana dashboardJust configure it accordingly nginx config http access log format remote addr remote user time local geoip country code http host request status body bytes sent request time http referer http user agent upstream addr upstream status upstream response time Keep the default log variables and add the country code ConclusionGeo routing is a requirement for successful apps and businesses Apache APISIX doesn t provide it out of the box In this post I showed how it could still be straightforward to set it up using the power of Nginx You can find the source code for this post on GitHub ajavageek apisix georouting To go further Module ngx http geoip moduleConverting Static Modules to Dynamic ModulesCustomize
