Each service shares only the framework code and the Api service located in services/Api/Api.php. Each service including main app can interact with other services only through Api service. Api service will use internal routing in monolith. When dividing monolith into microservices only this has to change.
| file or dir | action |
|---|---|
| storage/ | make it writable by apache |
| public/index.php | change to $app->run($app['request']) |
| bootstrap/app.php | uncomment Dotenv::load |
| bootstrap/app.php | uncomment $app->withFacades() |
| bootstrap/app.php | move app route group to app/Http/routes.php |
| .env | copy .env.example to .env |
| conifg/ | copy vendor/laravel/lumen-framework/config/ |
| app/Http/routes.php | add $app->configure('app') |
| services/ | mkdir services and use app dir structure for each service and change namespaces, filenames etc. |
| composer.json | add "Services\\": "services/" and run composer dump-autoload |
| bootstrap/app.php | add services/ServiceName/Http/routes.php |
| config/services/ | mkdir services and add service specific config here |
| services/ServiceName/Http/routes.php | add $app->configure('services/service_name') |
- Make copies of the framework code and do initial setup for each microservice
- Copy config/services/service_name.php and services/ServiceName/ dir
- Copy other config like config/database.php that is used by common services like
DB,Cacheetc. - Keep only current service routes in bootstrap/app.php
- Implement
Apiservice to make requests to respective endpoints instead of doing internal routing
# cd to www root
mkdir test && cd test
git clone https://github.com/marella/test-lumen.git
cd test-lumen/monolith
composer install
# now cd to other dirs (app, service_a, service_b) and run composer install
# or simply copy composer.lock and vendor dirIf required change $base_url in services/Api/Api.php inside test-lumen/app/, test-lumen/service_a/ and test-lumen/service_b/. Default $base_url is http://localhost/test/test-lumen/.
