VScode Sorbet enable only the LSP, instead of the typecheck

Question

We have a large Ruby on Rails started at ROR version 4 (recently upgraded to ROR 7, with Ruby 3.2.1).

-> Now the issue is till date we were using the JetBrains RubyMine with docker-compose setup, RubyMine - docker-compose setup, everything was working fine with rubocop, debugger. gem files navigation, and RubyMines intellisense.

-> Now we are planning to stop the RubyMine subscription and started the migration to VScode.

I'm trying to containerize the setup using VSCodes devcontainer feature with the existing docker-compose.yml file configured exsting. I have successfully setted up the ruby-lsp (from shopify). But when I try to setup Sorbet, I have following confusions and issues,

I only wanted the Sorbet's LSP for my project (type checking is not required) - main

For sorbet I need the Sorbet's gem to be installed, but I don't want the existing application's Gemfile to be polluted. Therefore I have created another Gemfile under the .devcontainer folder and added required gems.

Is solargraph is any way better than sorbet.

What is the best way to achieve this requirement?

}

This is my devcontainer config, and also each time I want to bundle the gems even though the docker-compose does that.

Please help out.

I have successfuly launched the code base in devcontainer using the above config.

The Ruby LSP is working as expected.

But for sorbet,

1. I have successfully initialized the tapioca But the issue is I only want the sorbet's LSP, type checking is not my need.

So what will be the best conclusion.

1. Can I able to add the required gems without intefering my main application?
