Jhipster Monolith with MongoDB with Keycloak Using MySql

[sthraki]

Hi ,

I was wondering if it's possible to have a Jhipster Spring Monolith with Keycloak , where Spring app uses MongoDB and Keycloak uses Mysql . Is it possible to configure JDL like that and generate app ?

Hi @sthraki and welcome!

The spring app using mongo and keycloak are of course possible: just use the relative options in jdl (authenticationType: oauth2, databaseType: mongodb). For the keycloak database, JHipster uses the default provided by the KC community: I don't know which one it is TBH, I think it's H2.
Still, note that the third party services (Keycloak, Redis, Elasticsearch, Consul, even databases) are not meant to be deployed as is in production: Jhipster provides a default configuration to ease the bootstrap locally or in development environment, but you'll have to install these soft by yourself in your IT environment to get production-grade services.
For example:

• Databases are not scaled by default, do not have automated backups
• ES is not secured with Oauth2
• Keycloak is not replicated neither uses a production-ready database.

Contribution to JH making these production-grade third party services for 'prod' profile could be a nice addition.
