How to validate Polyaxonfiles (YAML) against the JSON Schema on VSCode.


Polyaxon provides a JSON Schema that enables validation of YAML resources in your VSCode IDE.

Install Red Hat YAML plugin

In VSCode, you can use Red Hat YAML plugin, it provides error highlighting and auto-completion for Polyaxonfiles.



Open the YAML schemas settings:


Configure your IDE to reference Polyaxonfile’s schema:


The schema is located at

We recommend to use a file glob pattern that is specific to your Polyaxonfiles, for example:

  • polyaxonfile*.yaml: All files that start with polyaxonfile and end with .yaml.
  • polyaxonfiles/**/*.yaml: All files located under polyonaxfiles path.

Restart the IDE to use the completion and validation

After configuring the IDE correctly, if you open a polyaxonfile you should see a smarter behaviour, including type errors and context-sensitive autocomplete.


Note: the completion on VSCode has still some issue under the run section.
