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

💡 Result:

<search_synthesis>
The open-pull-requests-limit option in your dependabot.yml file is used to manage the number of open pull requests created by Dependabot version updates [1][2]. Key details regarding this option include: Default Behavior: By default, Dependabot allows a maximum of 5 open pull requests for version updates at any given time [1][3][2]. If this limit is reached, Dependabot will not open new pull requests until existing ones are merged or closed [1][2]. Security Updates: Pull requests generated by security updates are not subject to the open-pull-requests-limit and do not count toward this total [1][2]. There is no default limit on the number of open pull requests for security updates [2]. Disabling Updates: You can effectively disable version updates for a specific package ecosystem by setting open-pull-requests-limit to 0 [1][4][2]. This technique is often used when a repository owner wishes to receive only security updates for a particular package manager while excluding version updates [4][5]. Configuration: This option is defined under the updates section of your dependabot.yml file for each package ecosystem [3]. Example: updates: - package-ecosystem: "npm" directory: "/" schedule: interval: "weekly" # Set limit to 10 open version update PRs open-pull-requests-limit: 10 Source [1], [4], [2] provide the technical foundation for this behavior.

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>customizing-dependabot-security-prs</title> https://docs.github.com/en/enterprise-cloud@latest/code-security/how-tos/secure-your-supply-chain/manage-your-dependency-security/customizing-dependabot-security-prs 1. Check in a `dependabot.yml` file into the `.github` directory of your repository. For more information, see [Configuring Dependabot version updates](/en/enterprise-cloud@latest/code-security/how-tos/secure-your-supply-chain/secure-your-dependencies/configure-version-updates#enabling-dependabot-version-updates). 2. Set all the required keys. For more information, see [Required keys](/en/enterprise-cloud@latest/code-security/reference/supply-chain-security/dependabot-options-reference#required-keys). 3. If you want the customization for a package ecosystem to **only apply to security updates** (and exclude version updates), set the `open-pull-requests-limit` key to `0`. ... ## Example 1: configuration for security updates only ... In this example, the `dependabot.yml` file: ... * Uses a private registry for updates to npm dependencies. * Disables version updates for dependencies, so that any customizations apply to security updates only. * Is customized so that Dependabot applies custom labels to the pull requests and automatically adds assignees. * Groups security updates for golang dependencies into a single pull request. ... updates: - package-ecosystem: "npm" directory: "/src/npm-project" schedule: interval: "daily" # For Lodash, ignore all updates ignore: - dependency-name: "lodash" # Disable version updates for npm dependencies open-pull-requests-limit: 0 registries: # Ask Dependabot to use the private registry for npm - example # Raise all npm pull requests for security updates with custom labels labels: - "npm dependencies" - "triage-board" # Raise all npm pull requests for security updates with assignees assignees: - "user-name" - package-ecosystem: "gomod" directories: - "**/*" schedule: interval: "weekly" open-pull-requests-limit: 0 groups: # Group security updates for golang dependencies # into a single pull request golang: applies-to: security-updates patterns: - "golang.org*" ... ## Example 2: configuration for version updates and security updates ... In this example, the `dependabot.yml` file: * Is customized so that Dependabot adds custom labels to both version updates and security updates. * Uses the `groups` customization option to create two groups ("`angular`" and "`production-dependencies`") in order to group multiple updates into single pull requests. * Specifies that the `groups` customization for `angular` applies to security updates only. * Specifies that the `groups` customization for `production-dependencies` applies to version updates only. ... ```yaml copy ... version: 2 ... updates: # Keep npm dependencies up to date - package-ecosystem: "npm" directory: "/" schedule: interval: "weekly" ... # Raise all npm pull requests for security and version updates with custom labels labels: - "npm dependencies" - "triage-board" groups: angular: # Group security updates for Angular dependencies into a single pull request applies-to: security-updates patterns: - "`@angular`*" production-dependencies: # Group version updates for dependencies of type "production" into a single pull request applies-to: version-updates dependency-type: "production" ... * [Dependabot options reference](/en/enterprise-cloud@latest/code-security/reference/supply-chain-security/dependabot-options-reference) * [Configuring access to private registries for Dependabot](/en/enterprise-cloud@latest/code-security/how-tos/secure-your-supply-chain/manage-your-dependency-security/configure-access-to-private-registries)

Confirm the pull-request limit scope.

open-pull-requests-limit applies only to version-update pull requests. Security-update pull requests do not count towards this limit and can still be opened, including when Cargo is set to 0. If the policy must cap all open Dependabot pull requests, these settings do not enforce it. Confirm that the policy is version-update-only or define how security-update pull requests will be managed.
