Renovate shared presets

Presets makes rules easier to maintain and reusable across multiple repositories.

How to use a preset

Reference the preset in the extends field of the renovate.json file in the repository.
Presets can reference other presets. (read more about shared presets)

{
  "extends": [
    "github>argoproj/argo-cd//renovate-presets/custom-managers/bash.json5"
]
}

Note :

It would make sense to move this folder to a new repository in the future.

Benefits:

• Avoids consuming the repository's CI/CD resources.
• Faster feedback loop for configuration changes.
• Avoid polluting the master git history.
• The renovate.json in each repository can be simplified to only include a single presets :
  jsonCopy

  {
    "$schema": "https://docs.renovatebot.com/renovate-schema.json",
    "extends": [
      "github>argoproj/renovate-presets//argoproj/argo-cd/renovate.json5"
    ],
    // rules are empty and this file won't need to be modified again.
    "packageRules": []
  }
  

Inconvenient:

• Owners of a repository can impact the configuration of all repositories. Use codeowners to reduce the risk.
