GitHub Dependabot options reference open-pull-requests-limit 0 version updates security updates

💡 Result:

<search_synthesis>
In GitHub Dependabot, the open-pull-requests-limit configuration option controls the maximum number of open pull requests for version updates [1][2]. Setting open-pull-requests-limit: 0 has the following specific effects: 1. Disables Version Updates: It effectively disables all automated version update pull requests for the specified package-ecosystem [1][3][4]. 2. Security Updates Remain Enabled: Crucially, this limit does not apply to security updates [1][2]. Dependabot will continue to generate and open pull requests for security vulnerabilities even when the limit is set to zero [3][5][6]. 3. Configuration Usage: When set to zero, the dependabot.yml configuration for that ecosystem remains active and can be used to customize, label, assign, or group security update pull requests [3][7]. If you wish to prevent Dependabot from opening any pull requests at all (including security updates), you must disable security updates separately in the repository&#39;s security settings via the GitHub UI, rather than through the dependabot.yml file [6]. Setting an extremely high integer for open-pull-requests-limit is the supported way to effectively remove the cap on open version update pull requests [1][5][2].

Users with write access Copy as Markdown ## In this article ## Managing Dependabot security updates for your repositories You can enable or disable Dependabot security updates for all qualifying repositories owned by your personal account or organization. For more information, see Managing security and analysis features or Managing security and analysis settings for your organization. You can also enable or disable Dependabot security updates for an individual repository. ### Enabling or disabling Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security. To the right of "Dependabot security updates," click Enable to enable the feature or Disable to disable it. For public repositories, the button is disabled if the feature is always enabled. ## Grouping Dependabot security updates into a single pull request In order to use grouped security updates, you must first enable the following features: - Dependency graph. For more information, see Enabling the dependency graph. - Dependabot alerts. For more information, see Configuring Dependabot alerts. - Dependabot security updates. For more information, see Configuring Dependabot security updates. Note When grouped security updates are first enabled, Dependabot will immediately try to create grouped pull requests. You may notice Dependabot closing old pull requests and opening new ones. You can enable grouped pull requests for Dependabot security updates in one, or both, of the following ways. - To group as many available security updates together as possible, across directories and per ecosystem, enable grouping in the "Advanced Security" settings for your repository, or in "Global settings" under Advanced Security for your organization. - For more granular control of grouping, such as grouping by package name, development/production dependencies, SemVer level, or across multiple directories per ecosystem, add configuration options to the`dependabot.yml` configuration file in your repository. Note If you have configured group rules for Dependabot security updates in a`dependabot.yml` file, all available updates will be grouped according to the rules you&`#39`;ve specified. Dependabot will only group across those directories not configured in your`dependabot.yml` if the setting for grouped security updates at the organization or repository level is also enabled. ### Enabling or disabling grouped Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security. Under "Dependabot," to the right of "Grouped security updates," click Enable to enable the feature or Disable to disable it. ### Enabling or disabling grouped Dependabot security updates for an organization You can enable grouped Dependabot security updates into a single pull request. For more information, see Configuring global security settings for your organization. ## Overriding the default behavior with a configuration file You can override the default behavior of Dependabot security updates by adding a`dependabot.yml` file to your repository. With a`dependabot.yml` file, you can have more granular control of grouping, and override the default behavior of Dependabot security updates settings. Use the`groups` optio…[truncated] <title>Configuring Dependabot version updates - GitHub Enterprise Server 3.7 Docs</title> https://help.github.com/en/enterprise-server@3.7/code-security/dependabot/dependabot-version-updates/configuring-dependabot-version-updates You enable Dependabot version updates by checking a`dependabot.yml` configuration file in to your repository&`#39`;s`.github` directory. Dependabot then raises pull requests to keep the dependencies you configure up-to-date. For each package manager&`#39`;s dependencies that you want to update, you must specify the location of the package manifest files and how often to check for updates to the dependencies listed in those files. For information about enabling security updates, see " Configuring Dependabot security updates." ... To keep pull requests manageable and easy to review, Dependabot raises a maximum of five pull requests to start bringing dependencies up to the latest version. If you merge some of these first pull requests before the next scheduled update, remaining pull requests will be opened on the next update, up to that maximum. You can change the maximum number of open pull requests by setting the open-pull-requests-limit configuration option. ... By default only direct dependencies that are explicitly defined in a manifest are kept up to date by Dependabot version updates. You can choose to receive updates for indirect dependencies defined in lock files. For more information, see " Configuration options for the dependabot.yml file." ... When running security or version updates, some ecosystems must be able to resolve all dependencies from their source to verify that updates have been successful. If your manifest or lock files contain any private dependencies, Dependabot must be able to access the location at which those dependencies are hosted. Organization owners can grant Dependabot access to private repositories containing dependencies for a project within the same organization. For more information, see " Managing security and analysis settings for your organization." You can configure access to private registries in a repository&`#39`;s`dependabot.yml` configuration file. For more information, see " Configuration options for the dependabot.yml file." Additionally, Dependabot doesn&`#39`;t support private GitHub dependencies for all package managers. For more information, see " About Dependabot version updates" and " GitHub language support." ... Add an`updates` section, with an entry for each package manager you want Dependabot to monitor. ... - `package-ecosystem` to specify the package manager. - `directory` to specify the location of the manifest or other definition files. - `schedule.interval` to specify how often to check for new versions. ... You can disable version updates entirely by deleting the`dependabot.yml` file from your repository. More usually, you want to disable updates temporarily for one or more dependencies, or package managers. ... - Package managers: disable by setting`open-pull-requests-limit: 0` or by commenting out the relevant`package-ecosystem` in the configuration file. - Specific dependencies: disable by adding`ignore` attributes for packages or applications that you want to exclude from updates. ... When you disable dependencies, you can use wild cards to match a set of related libraries. You can also specify which versions to exclude. This is particularly useful if you need to block updates to a library, pending work to support a breaking change to its API, but want to get any security fixes to the version you use. ... ``` # `dependabot.yml` file with updates # disabled for Docker and limited for npm ... version: 2 ... updates: # Configuration for Dockerfile - package-ecosystem: "docker" directory: "/" schedule: interval: "weekly" # Disable all pull requests for Docker dependencies open-pull-requests-limit: 0 # Configuration for npm - package-ecosystem: "npm" directory: "/" schedule: interval: "weekly" ignore: # Ignore updates to packages that start with &`#39`;aws&`#39`; # Wildcards match zero or more arbitrary characters - dependency-name: "aws*…[truncated] <title>Document how to remove limits in Dependabot</title> GitHub issue 41359 in github/docs (link omitted to avoid creating a cross-reference) https://docs.github.com/en/code-security/dependabot/working-with-dependabot/dependabot-options-reference#open-pull-requests-limit- ... By default, Dependabot sets [`open-pull-requests-limit` to 5](https://docs.github.com/en/code-security/dependabot/working-with-dependabot/dependabot-options-reference#open-pull-requests-limit-), and setting it to `0` disables the ecosystem entirely. What remains unclear is whether there’s an officially supported way to remove this limit. ... I understand that setting a very large integer (e.g., `1000000`) removes the limit for most practical use cases, but it is unclear if this is what the team recommends to remove the limit ... > `@yeikel` Right, sorry. Officially, there&`#39`;s no way to remove the limits. According to one of the engineers I talked to, the maximum allowed is 100. I&`#39`;m not sure what the reasoning is behind that, but I can ask if that would be helpful. ... > Hi `@yeikel`! There is no way to remove the limit, but setting an arbitrarily high number will work. > > As far as I can tell there is no limit at 100 and Dependabot should happily keep creating PRs until update config hits the user&`#39`;s `open-pull-request-limit`. > > The mix up may have come from our pause notifier which updates the 100 most recent PRs to tell a user that their repo is paused. A lot of the methods in that class have similar names to the open pull request limit methods. > > A couple of other bits of info: > - Setting the `open-pull-request-limit` to 0 will stop an update config from creating new version updates, but Dependabot will still create security updates, and it will use the update config for the security update if the directory matches. > - Negative `open-pull-request-limits` are "valid" but they are not supported. We don&`#39`;t special case them and they will probably break your update config. ... > Hi `@Nishnha` > > Thank you for the insights! > > I did some testing on this and here’s what I observed on a [test repo](https://github.com/yeikel/dependabot-limit-tests): > > 1) Increasing the limit [does work as a workaround](https://github.com/yeikel/dependabot-limit-tests/blob/598287e09c671226539b7ecf473a685afd2dbaeb/.github/dependabot.yml#L4). Using negative numbers, as you suggested, seems to break it as suggested. > 2) There doesn’t appear to be a hard limit. I was able to open [more than 100 pull requests](https://github.com/yeikel/dependabot-limit-tests/pulls). Referring back to what `@Sharra-writes` mentioned, is there a specific bug being tracked to change this? > > Regarding the comment about the pause notifier updating the 100 most recent PRs to inform users their repo is paused: > > Does this refer to the [Pause due to inactivity](https://github.blog/changelog/2023-01-12-dependabot-pull-requests-pause-for-inactivity/) feature or do you issue a pause after 100+ pull requests? > > Based on my testing, even with over 100 open pull requests, Dependabot continues to update them without issue. But my repo did not reach the inactivity documented above ... > It refers to the pause due to inactivity 👍 > > > is there a specific bug being tracked to change this? > > I&`#39`;ll open up a docs change to recommend setting an arbitrarily high value to disable the limit. It will be internal so I can&`#39`;t link it here, but I&`#39`;ll try to land it early next week. ... - Referenced by PR `#633`: docs(runbooks): add dependency update workflow runbook

Confirm the Cargo update policy.

open-pull-requests-limit: 0 disables Cargo version-update pull requests. Security-update pull requests are not subject to this limit. If routine Cargo updates must continue, set an approved positive limit; otherwise, document that this setting is intentional.
