yaml-language-server VS vscode-yaml

Does anyone know how to get yaml formatting working with yamlls (https://github.com/redhat-developer/yaml-language-server)?

I'm starting to work with kubernetes and it would be really nice to have the full completion that Redhat's language server offers for k8s yaml files if you associate the right schema with it.

Most modern editors and IDEs support the Language Server Protocol, which powers the code completion, validation, and tooltip features. Combined with a Yaml Language Server, we can get rich completion for Yaml files!

I don't think the YAML language server can handle this. Here's the issue about this: https://github.com/redhat-developer/yaml-language-server/issues/220

Here's an example .dir-locals.el configuration I'm using with yaml-language-server

Check out https://github.com/redhat-developer/yaml-language-server if you want to get that IDE experience with YAML from those openapi specs

For our custom LSP, we'll start by forking the yaml-language-server maintained by redhat.

One of the things I was missing in my nvim setup was the ability to choose the schema that yamlls uses in the various buffers. This server also intentionally leaves out some cool features like content aware schema detection and, since I could never get the Schema Store functionality to work when paired with the hard-coded Kubernetes support in the language server… I have converted all the hacky lua I had into this plugin. Sharing it here in case it is useful to anyone https://github.com/someone-stole-my-name/yaml-companion.nvim

What I'm missing in Nickel is schema validation. With JSON schemas, you can specify exactly what shape the configuration file should have, and provide autocompletion and error highlighting in an editor. JSON schemas can also be used for toml and yaml.

Install any kubernetes yaml validator in your vscode https://github.com/redhat-developer/vscode-yaml

Have a K8yaml schemaset to K8's in your editor. Something like this makes the process so smooth.
