Hi @ohbus @championswimmer can I pick this up? Thanks

[championswimmer]

@subhatanay go ahead :)

Right now it is very early stage of the project, very few contributors, so you can just write "I am picking this up" instead of waiting for permission

@subhatanay, hey, let me know if you need any help with this issue. :) I was working on it for a while.

Hi @alpha037 .. Currently working on this. Dockerfile is done .. planing to move the Configs to .env file instead of app.module.ts file. Which can be used both via application as well the docker-compose file

Will try to raise a pull request by today night

thanks

@subhatanay, sounds great! @nestjs/config should do the trick.

@championswimmer @ohbus @subhatanay, hey guys, don't we need to wait for the database instance to get ready to accept connections?

Even after the db instance starts up, I guess it takes some time to accept other connections maybe?

Hi @alpha037 .. I had gone through this docker docs. Without this also it works fine postgres starts and then app docker starts. Also application also have a retry logic which can retry until a application properly start. Felt like not needed now. If all saying needed i can implement then.
