# Push Rules **(STARTER)**
|
|
|
|
Gain additional control over what can and can't be pushed to your repository by using
|
|
regular expressions to reject pushes based on commit contents, branch names or file details.
|
|
|
|
## Overview
|
|
|
|
GitLab already offers [protected branches][protected-branches], but there are
|
|
cases when you need some specific rules like preventing Git tag removal or
|
|
enforcing a special format for commit messages.
|
|
|
|
Push rules are essentially [pre-receive Git hooks][hooks] that are easy to
|
|
enable in a user-friendly interface. They are defined globally if you are an
|
|
admin or per project so you can have different rules applied to different
|
|
projects depending on your needs.
|
|
|
|
## Use cases
|
|
|
|
Every push rule could have its own use case, but let's consider some examples.
|
|
|
|
### Commit messages with a specific reference
|
|
|
|
Let's assume you have the following requirements for your workflow:
|
|
|
|
- every commit should reference a Jira issue, for example: `Refactored css. Fixes JIRA-123.`
|
|
- users should not be able to remove Git tags with `git push`
|
|
|
|
All you need to do is write a simple regular expression that requires the mention
|
|
of a Jira issue in the commit message, like `JIRA\-\d+`.
|
|
|
|
Now when a user tries to push a commit with a message `Bugfix`, their push will
|
|
be declined. Only pushing commits with messages like `Bugfix according to JIRA-123`
|
|
will be accepted.
|
|
|
|
### Restrict branch names
|
|
|
|
Let's assume there's a strict policy for branch names in your company, and
|
|
you want the branches to start with a certain name because you have different
|
|
GitLab CI jobs (`feature`, `hotfix`, `docker`, `android`, etc.) that rely on the
|
|
branch name.
|
|
|
|
Your developers however, don't always remember that policy, so they push
|
|
various branches and CI pipelines do not work as expected. By restricting the
|
|
branch names globally in Push Rules, you can now sleep without the anxiety
|
|
of your developers' mistakes. Every branch that doesn't match your push rule
|
|
will get rejected.
|
|
|
|
### Custom Push Rules **(CORE ONLY)**
|
|
|
|
It's possible to create custom push rules rather than the push rules available in
|
|
**Admin Area > Push Rules** by using more advanced server hooks.
|
|
|
|
See [server hooks](../administration/server_hooks.md) for more information.
|
|
|
|
## Enabling push rules
|
|
|
|
NOTE: **Note:**
|
|
GitLab administrators can set push rules globally under
|
|
**Admin Area > Push Rules** that all new projects will inherit. You can later
|
|
override them in a project's settings.
|
|
|
|
1. Navigate to your project's **Settings > Repository** and expand **Push Rules**
|
|
1. Set the rule you want
|
|
1. Click **Save Push Rules** for the changes to take effect
|
|
|
|
The following options are available.
|
|
|
|
| Push rule | GitLab version | Description |
|
|
| --------- | :------------: | ----------- |
|
|
| Removal of tags with `git push` | **Starter** 7.10 | Forbid users to remove Git tags with `git push`. Tags will still be able to be deleted through the web UI. |
|
|
| Check whether author is a GitLab user | **Starter** 7.10 | Restrict commits by author (email) to existing GitLab users. |
|
|
| Committer restriction | **Premium** 10.2 | GitLab will reject any commit that was not committed by the current authenticated user |
|
|
| Check whether commit is signed through GPG | **Premium** 10.1 | Reject commit when it is not signed through GPG. Read [signing commits with GPG][signing-commits]. |
|
|
| Prevent committing secrets to Git | **Starter** 8.12 | GitLab will reject any files that are likely to contain secrets. Read [what files are forbidden](#prevent-pushing-secrets-to-the-repository). |
|
|
| Restrict by commit message | **Starter** 7.10 | Only commit messages that match this regular expression are allowed to be pushed. Leave empty to allow any commit message. Uses multiline mode, which can be disabled using `(?-m)`. |
|
|
| Restrict by commit message (negative match)| **Starter** 11.1 | Only commit messages that do not match this regular expression are allowed to be pushed. Leave empty to allow any commit message. Uses multiline mode, which can be disabled using `(?-m)`. |
|
|
| Restrict by branch name | **Starter** 9.3 | Only branch names that match this regular expression are allowed to be pushed. Leave empty to allow any branch name. |
|
|
| Restrict by commit author's email | **Starter** 7.10 | Only commit author's email that match this regular expression are allowed to be pushed. Leave empty to allow any email. |
|
|
| Prohibited file names | **Starter** 7.10 | Any committed filenames that match this regular expression are not allowed to be pushed. Leave empty to allow any filenames. |
|
|
| Maximum file size | **Starter** 7.12 | Pushes that contain added or updated files that exceed this file size (in MB) are rejected. Set to 0 to allow files of any size. Files tracked by Git LFS are exempted. |
|
|
|
|
TIP: **Tip:**
|
|
GitLab uses [RE2 syntax](https://github.com/google/re2/wiki/Syntax) for regular expressions in push rules, and you can test them at the [GoLang regex tester](https://regex-golang.appspot.com/assets/html/index.html).
|
|
|
|
## Prevent pushing secrets to the repository
|
|
|
|
> [Introduced][ee-385] in [GitLab Starter][ee] 8.12.
|
|
|
|
You can turn on a predefined blacklist of files which won't be allowed to be
|
|
pushed to a repository.
|
|
|
|
By selecting the checkbox *Prevent committing secrets to Git*, GitLab prevents
|
|
pushes to the repository when a file matches a regular expression as read from
|
|
[`files_blacklist.yml`][list] (make sure you are at the right branch
|
|
as your GitLab version when viewing this file).
|
|
|
|
NOTE: **Note:**
|
|
Files already committed won't get restricted by this push rule.
|
|
|
|
Below is an example list of what will be rejected by these regular expressions:

<!-- ## Troubleshooting
|
|
|
|
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
|
|
one might have when setting this up, or when something is changed, or on upgrading, it's
|
|
important to describe those, too. Think of things that may go wrong and include them here.
|
|
This is important to minimize requests for support, and to avoid doc comments with
|
|
questions that you know someone might ask.
|
|
|
|
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
|
|
If you have none to add when creating a doc, leave this section in place
|
|
but commented out to help encourage others to add to it in the future. -->
