Re: [Architecture] [AF] Datasources for PHP application type
Hi Ajantan, Yes this can be done in PPaaS. We implemented web app which has simple REST api s to act as a metadata service. In addition we we extended cartridge agents of MySQL and PHP. MySQL cartridge sends its details(IP,credentials, some other data required) to metadata service by calling REST api. We used simple python scripts to call the metadata service's REST api. PHP cartridge agent get those db details via the metadata service. After fetching those details they can be set as environment variables or write to a config file etc. I can share the python scripts and web app. Touched, not typed. Erroneous words are a feature, not a typo.

I can explain in detail if this is feasible for you. Most of the PAASes out there following this approach to inject database details into app.In our case user may edit this parameter after first deploy, is it possible to do it in private PAAS? Are there any API that we can push those details and notify cartridge agent to update restart after launching cartridge? Touched, not typed.

Re: [Architecture] [AF] Datasources for PHP application type
Hi Madhawa, We can keep these variables(string $dsn , string $user , string $password) in registry and use registry rest API to get values at runtime. So when you promote the application to Test and Production environments, application will pick the environment specific values. This will not break PHP developer experience as well. thank you.

Re: [Architecture] [AF] Datasources for PHP application type
Hi Madhawa. We can keep these variables(string $dsn , string $user , string $password) in registry and use registry rest API to get values at runtime. So when you promote the application to Test and Production environments, application will pick the environment specific values. This will not break PHP developer experience as well. +1 for above answer. Moreover AFAIK we can not directly run piece of java code inside php script as php is a interpreted language. Cleanest way would be expose a web-service but there is a ugly way you can execute a jar file from php script using shell_exec() [1].
