Inline Mongo DB chart

[WhammyLeaf]

This PR inlines the charts for mongodb so that librechat will not have a dependency on bitnami which has become unreliable after their recent transition into commercial offerings.

I know the amount of code is alot. It may be better to host the code in a registry that librechat owns long term. But for now this works.

Thanks for raising this concern about Bitnami's transition. However, inlining 14,500+ lines of chart code isn't the right solution here.

The good news: Bitnami's Helm chart source code remains open source and actively maintained on GitHub under Apache 2 license. Only the pre-packaged OCI artifacts are affected.

Better alternatives:

1. Use alternative providers:

   • Chainguard has forked Bitnami charts with drop-in compatibility: oci://cgr.dev/chainguard/mongodb
   • Percona MongoDB: https://percona.github.io/percona-helm-charts/

2. Override image sources in the existing chart:

mongodb:
  image:
    registry: cgr.dev
    repository: chainguard/mongodb

Inlining makes the chart unmaintainable and harder to update.

First of all, I agree that inlining 15 K lines of code is not ideal. As for your suggestions, I am not sure either is a good option.

Chainguard does not open source their charts and their helm chart documentation is not very good. This seems like another commercial company that may do a bitnami rug pull at any time.

Percona is also a commercial company but their charts are open sourced I think. However, I dont think their chart is a drop in replacement. Their chart is specifically made for their own MongoDB offering (which is built on top of the community version). It is free but the chart is using an operator so the setup is different.

In general: there are very few, if any, alternatives to bitnami, which are both drop-in and open-sourced. The only I could really find is this: https://github.com/CloudPirates-io/helm-charts. Their MongoDB chart might work well for LibreChat, although from what I can tell it is somewhat barebones.

Unless you want to wait until the ecosystem has matured and a full-fledged open-sourced alternative is available, I think the best solution is for you to host a MongoDB chart yourself. I found this tool from bitnami, which supposedly allows you to easily sync charts to your own registry. That might be useful for you, although I have not tried it myself.
