chore(renovate): add org-wide shared Renovate config - #4
Conversation
The org has no consistent dependency or security automation. Ten of twelve code repos have none at all, the Renovate app is not installed, and the two existing renovate.json stubs are dead config nothing acts on. This adds the single source of truth every repo will extend: - renovate-config.json: the org policy. Security fixes raised immediately and labeled, everything else batched into Monday morning and grouped into a handful of combined PRs. No automerge - six repos have no tests. - Two custom managers for things no built-in manager can see: the student IDE images that EduIDE-deployment pins as a plain YAML list under preloading.images (12 production images, currently invisible), and the theiaPlugins GitHub release URLs in EduIDE/package.json. - A CI job running renovate-config-validator --strict. A typo in this file breaks eleven repos at once, so it gets its own gate. - A reusable dependency-review workflow for repos to call on PRs. - renovate/README.md covering how to add a repo, change policy org-wide, and test a preset change before it reaches everything.

GitHub actions/checkout v4 persist-credentials default local git config GITHUB_TOKEN official README
💡 Result:
In GitHub Actions, the actions/checkout@v4 action uses a default value of true for the persist-credentials input [1][2]. When this option is enabled (the default), the action configures the authentication token (GITHUB_TOKEN) or SSH key in the local git configuration [3][1]. This allows subsequent steps in your job to run authenticated git commands against the repository [3][4]. For security, the action automatically removes this token during the post-job cleanup process [3][5]. If you wish to prevent the action from storing these credentials in the local git configuration, you can explicitly set persist-credentials to false in your workflow file [3][4].

GitHub Actions workflow permissions contents read GITHUB_TOKEN official documentation reusable workflow permissions
💡 Result:
In GitHub Actions, the GITHUB_TOKEN is an automatically generated, short-lived token used to authenticate API requests within a workflow [1][2]. Its permissions can be explicitly controlled using the permissions key at either the workflow or job level [3][2][4]. Key aspects of managing GITHUB_TOKEN permissions: 1. Permission Levels: You can set permissions to read, write, or none for various scopes (e.g., contents, issues, packages) [5][2]. If the permissions key is defined, any scope not explicitly listed is set to none [5][2][4]. If it is not defined, the workflow defaults to the repository or organization settings [6]. 2. Reusable Workflows: - Token Limitation: The GITHUB_TOKEN granted to a reusable workflow is capped by the permissions explicitly set in the calling workflow job [7][8]. The called workflow cannot elevate permissions beyond those granted by the caller [7][9]. - Default Behavior: If the calling job does not specify permissions, the called workflow receives the default GITHUB_TOKEN permissions [7]. - Best Practice: To avoid 403 "Resource not accessible" errors, you should grant the necessary write permissions in the caller job (e.g., contents: write) and ensure the reusable workflow also declares the required permissions in its own job definition [8]. This ensures that the effective token has the minimum necessary privileges while adhering to the principle of least privilege [8][3]. 3. Contents Permission: Specifying contents: read allows actions to clone and fetch the repository, while contents: write is required for tasks such as pushing code, creating releases, or modifying files [5][6]. In summary, when using reusable workflows, always explicitly define the required permissions in the calling job to ensure the invoked workflow has sufficient access, while keeping the scope as restrictive as possible [8][6].

Set persist-credentials: false on both affected checkout steps.
actions/checkout@v4 stores GITHUB_TOKEN in .git/config by default. The subsequent npx command and dependency-review action can read this configuration if compromised. The workflows declare contents: read; retain least-privilege permissions in callers of the reusable workflow.

Renovate packageRules matchFileNames groupName later matching rules merge behavior
💡 Result:
In Renovate, packageRules follow a specific evaluation and merge process [1]. When multiple packageRules match a single dependency, Renovate evaluates all of them rather than stopping at the first match [1][2]. The configurations from all matching rules are merged together into a single effective configuration for that dependency [1][2]. The order of your packageRules is critical because they are applied sequentially [1]. While all matching rules are applied, later rules can override configuration options from earlier ones if both rules specify the same option [1][2]. Regarding merge behavior: - Mergeable Options: For configuration options defined as "mergeable" (typically array-based fields like addLabels or allowedVersions), values from all matching rules are combined [3][2]. - Non-Mergeable Options: For options that are not mergeable, a later matching rule will overwrite the value set by an earlier rule [3][2]. Because of this, it is recommended to order your packageRules with the least important rules at the top and the most specific or important rules at the bottom, ensuring that high-priority rules correctly override general settings [1]. When using groupName, it behaves like other configuration options within a packageRule [4]. If multiple matching rules specify different groupName values, the last matching rule that defines a groupName will determine the final group name for that dependency [1][2].

site:docs.renovatebot.com/configuration-options matchFileNames package file glob Renovate
💡 Result:
In Renovate, matchFileNames is a configuration option used within packageRules to selectively apply rules based on the path of the package file being processed [1]. Key points regarding matchFileNames: Purpose: It allows you to target specific directories or files for your packageRules [1]. For example, if you want to apply specific dependency update behavior only to files located within a charts/ directory, you can set "matchFileNames": ["charts/"] [1]. Glob Patterns: The option accepts glob patterns [1]. These patterns are used to match the file paths relative to the repository root [1]. Integration with BumpVersions: It is frequently used in conjunction with the bumpVersions configuration, which allows for manual version bumping of files that are not automatically managed by a standard package manager [1]. In this context, you can define filePatterns using variables like {{packageFileDir}} to dynamically target files relative to the identified package file [1]. Example usage: { "packageRules": [ { "matchFileNames": ["charts/"], "bumpVersions": [ { "filePatterns": ["{{packageFileDir}}/Chart.{yaml,yml}"], "matchStrings": ["version:\s(?[^\\s]+)"] } ] } ] } This configuration ensures that the defined bumpVersions logic only applies when the matched package file is located under the charts/ directory [1].

Restrict this rule to Docker image dependencies.
A non-major helmv3 or helmfile update under deployments/** also matches this later rule and can replace groupName: "helm charts" with "deployed image tags". Add "matchManagers": ["custom.regex"] and "matchDatasources": ["docker"] to target preloading.images entries only.

What and why
The org has no consistent dependency or security automation. Ten of twelve code repos have none at all. The Renovate app is not currently installed on the org (only CodeRabbit and arc-runners are), so the
renovate.jsonstubs inDocsandscorpioare dead config nothing is acting on, andscorpio/.github/dependabot.ymlis the unedited GitHub template withpackage-ecosystem: "", which is invalid and does nothing.This PR adds the single source of truth that every repo will extend. Follow-up PRs add a three-line
renovate.jsonto each repo, clean up the superseded bot files, and fix the CI gaps.Policy: security fixes raised immediately (outside the schedule, prefixed
fix(security):, labeledsecurity); everything else batched into Monday 00:00-07:00 Europe/Berlin and grouped into a handful of combined PRs; majors held behind a Dependency Dashboard tick;minimumReleaseAge: 5 daysagainst yanked/compromised releases.No automerge anywhere. Six of the eleven repos have no tests at all and two more have tests CI never runs, so nothing here has enough signal to merge unattended. It is a one-line change in the shared preset once that improves.
Two custom managers
Renovate's built-in managers cannot see either of these:
EduIDE-deployment/deployments/*/values.yamlpins the student IDE images as a plain YAML list underpreloading.images:. Thehelm-valuesmanager only understandsimage: {repository, tag}dicts andimage: repo:tagscalars. Verified against the real file: 12 production images that would otherwise get zero updates and zero security alerts. These are the images students actually run.EduIDE/package.jsontheiaPluginspins plugin tarballs by GitHub release URL. No manager reads custom manifest keys.Known gap
theiaPluginsalso pins two VSIXs from open-vsx.org. Renovate has no open-vsx datasource, so those stay manual. Documented inrenovate/README.mdwith the reasoning.How it was verified

A regex that matches nothing fails silently, so this mattered.actionlintclean on the modified and new workflows.abandonments:recommended,:semanticCommitTypeAll(chore),customManagers:githubActionsVersionsandcustomManagers:dockerfileVersionsconfirmed to exist upstream.Not yet verified: real grouping behaviour. That needs a
--dry-run=fullagainst the merged preset, which cannot run until this is onmain(preset resolution reads the default branch).Deployment impact
No runtime effect until the Renovate app is installed, which is deliberately the last step of the rollout - installing it before the repo configs are merged would open a wave of "Configure Renovate" onboarding PRs and preset-resolution failures.
Risk and rollback
Low while the app is uninstalled: these are inert files. Once it is installed, a bad rule shows up as noisy or missing PRs, not as anything merged - automerge is off everywhere. Rollback is reverting this commit; repos extending a missing preset fail closed (no PRs) rather than doing something wrong.
The
renovate-config-validatorCI job is the guard against a typo here taking out eleven repos at once. Its renovate version is pinned on purpose: an unpinnednpx renovateresolves to whatever is in the npx cache, which during authoring served version 37 and rejected valid current options.Summary by CodeRabbit
