I too would love a plugin for this.. I'd like to run the LSP server in a Fedora toolbox, then some sort of property in the project's compile_commands.json or .vimrc that tells it where to find the LSP server. (Fedora toolbox mounts your home directory, so paths etc shouldn't be a problem.)

At the moment, I run everything (toolchain, LSP server, nvim) in a toolbox. Works well, but it feels unecessary to have a copy of vim in every container.
