Create a pull request (PR)

Estimated reading time: 3 minutes

A pull request (PR) sends your changes to the Docker maintainers for review. You create a pull request on GitHub. A pull request “pulls” changes from your forked repository into the docker/docker repository.

You can see the list of active pull requests to Docker on GitHub.

Check your work

Before you create a pull request, check your work.

In a terminal window, go to the root of your docker-fork repository.
```
 $ cd ~/repos/docker-fork
```

Checkout your feature branch.

 $ git checkout 11038-fix-rhel-link
 Switched to branch '11038-fix-rhel-link'

Run the full test suite on your branch.
```
 $ make test
```
All the tests should pass. If they don’t, find out why and correct the situation.
Commit and push any changes that result from your checks.

Rebase your branch

Always rebase and squash your commits before making a pull request.

Checkout your feature branch in your local docker-fork repository.

This is the branch associated with your request.

Fetch any last minute changes from docker/docker.

 $ git fetch upstream master
 From github.com:docker/docker
  * branch            master     -> FETCH_HEAD

Start an interactive rebase.
```
 $ git rebase -i upstream/master
```

Rebase opens an editor with a list of commits.

 pick 1a79f55 Tweak some of the other text for grammar
 pick 53e4983 Fix a link
 pick 3ce07bb Add a new line about RHEL

Replace the pick keyword with squash on all but the first commit.
```
 pick 1a79f55 Tweak some of the other text for grammar
 squash 53e4983 Fix a link
 squash 3ce07bb Add a new line about RHEL
```
After you save the changes and quit from the editor, git starts the rebase, reporting the progress along the way. Sometimes your changes can conflict with the work of others. If git encounters a conflict, it stops the rebase, and prints guidance for how to correct the conflict.
Edit and save your commit message.
```
 $ git commit -s
```
Make sure your message includes your signature.
Force push any changes to your fork on GitHub.
```
 $ git push -f origin 11038-fix-rhel-link
```

Create a PR on GitHub

You create and manage PRs on GitHub:

Open your browser to your fork on GitHub.

You should see the latest activity from your branch.
Click “Compare & pull request.”

The system displays the pull request dialog.

The pull request compares your changes to the master branch on the docker/docker repository.
Edit the dialog’s description and add a reference to the issue you are fixing.

GitHub helps you out by searching for the issue as you type.
Scroll down and verify the PR contains the commits and changes you expect.

For example, is the file count correct? Are the changes in the files what you expect?
Press “Create pull request”.

The system creates the request and opens it for you in the docker/docker repository.

Where to go next

Congratulations, you’ve created your first pull request to Docker. The next step is for you learn how to participate in your PR’s review.
