Language Server Settings

The following settings are supported:

yaml.format.enable: Enable/disable default YAML formatter
yaml.validate: Enable/disable validation feature
yaml.schemas: Helps you associate schemas with files in a glob pattern
yaml.customTags: Array of custom tags that the parser will validate against. It has two ways to be used. Either an item in the array is a custom tag such as "!Ref" or you can specify the type of the object !Ref should be by doing "!Ref scalar". For example: "!Ref", "!Some-Tag scalar". The type of object can be one of scalar, sequence, mapping, map.

Associating a schema to a glob pattern via yaml.schemas:

When associating a schema it should follow the format below

yaml.schemas: {
    "url": "globPattern",
    "Kubernetes": "globPattern",
    "kedge": "globPattern"
}

e.g.

yaml.schemas: {
    "http://json.schemastore.org/composer": "/*"
}

e.g.

yaml.schemas: {
    "kubernetes": "/myYamlFile.yaml"
}

e.g.

yaml.schemas: {
    "kedge": "/myKedgeApp.yaml"
}

e.g.

yaml.schemas: {
    "http://json.schemastore.org/composer": "/*",
    "kubernetes": "/myYamlFile.yaml"
}

yaml.schemas extension allows you to specify json schemas that you want to validate against the yaml that you write. Kubernetes and kedge are optional fields. They do not require a url as the language server will provide that. You just need the keywords kubernetes/kedge and a glob pattern.
