This project is meant to provide a simple restful interface to interact with databases. It features the ability to act as a proxy between any servers over a TCP connection. Also, it has the ability to read selected tables and generate an OpenApi spec.

Currently, it supports the following databases:

• PostgresDB
• CockroachDB

mvn clean package
cd universal-database-proxy-rest
java -jar -Dproject.config=cfg/config.json target/universal-database-proxy-rest-1.0.2-fat.jar

1. Create a config.json file. You can use the file in docker/config.json as a base.
2. Update the postgresApi object.
   1. Set the enabled property to true
   2. Set the host to the address the HTTP Server should attach to. This can be localhost or 0.0.0.0 or some.address.com.
   3. Set the port to the port number the HTTP Server should listen for connection on. This can be any valid port number.
   4. Set the openApiFilePath to where you want the OpenApi file generated to be stored. For example: ./pgOpenApi.yaml
   5. Now the database object holds configuration regarding the database we are trying base of our API from.
   6. Set the host to the address of the database. For example: localhost or 0.0.0.0 or some.address.com. This can be the host in plain text or the name of an ENVIRONMENT VARIABLE.
   7. Set the port to the port number the database is listening for connections on. This can be any valid port number.
   8. Set the username to the database username the server should use to authenticate itself against your chosen database. This can be the username in plain text or the name of an ENVIRONMENT VARIABLE.
   9. Set the password to the database password the server should use to authenticate itself against your chosen database. This can be the password in plain text or an ENVIRONMENT VARIABLE. For example: admin or POSTGRES_PASSWORD
   10. Set the databaseName to the name of the database you want the OpenApi to be generated from. This can be the name of the database in plain text or the name of an ENVIRONMENT VARIABLE.
   11. Run the steps in the Installation section and set the -Dproject.config= argument to the path of the config.json file you just create.

There is a working example in the docker folder on how to integrate in a docker-compose file.
