The ONOS source code is stored at gerrit.onosproject.org. Setting up
git and Gerrit will allow you to easily fetch and test any version of ONOS, including releases, development versions, and patches that have been submitted for review. Setting up a Gerrit account and
ssh access will also enable you to submit your own patches to ONOS and also to participate in the ONOS code review process.
Read-only access to the ONOS source code via
Make sure you've installed
git, and then create a local clone of the source repository:
If all you want to do is compile and run ONOS, you've got the code and are ready to do so!
However, if you want to contribute code to ONOS, you need to configure git and Gerrit for
ssh access, as described below.
Generally, we recommend to use ssh way if you want to contribute code to ONOS, but there are some restrictions in some areas when using ssh, so if the ssh won't work in your location, please try to use https way to contribute to ONOS. The steps are similar to SSH except that you need to enter the username and password each time you submit the code.
Optional: Read-write access to the ONOS source code via Gerrit,
There are two ways to clone the code from Gerrit,
ssh://. Either way is fine for reading the code, but when it comes time to contribute your own patches the easiest and most secure way is to access Gerrit over SSH.
To make sure you're using the
ssh:// remote, first check the URLs of the remotes in your ONOS repository:
If you see
ssh:// URLs, everything is fine and you can move on to the next step (Configuring Gerrit). If you see https:// URLs, you should change them to ssh:// before continuing:
<username> with your Gerrit/Crowd username (the
<username> must be specifically provisioned in Gerrit Profile for
You can double-check the URL on Gerrit by logging in, going to Projects -> List, then clicking on 'onos', On the grey bar, click 'SSH', then just underneath the grey bar will appear 'git clone ssh://...'. This is the URL you should set your remote to in your local git repository.
<username> is configured in Settings->Profile->Username; the Username is not populated for new accounts by default.
Prospective contributors should configure their account to receive notifications about their code submissions. The Settings page is accessed from the user dropdown on the upper right of the page:
To configure contacts by going to Contact Information, and filling out the fields, and hitting Save Changes :
To subscribe to the project, go to Watched Projects and enter onos-next in the Project Name field of the page. Hitting return should add onos-next to a table under the search field:
As shown above, email notifications are also configured from here by checking off the types of notifications to receive.
Uploading SSH Public Keys（only for ssh）
An SSH key should also be uploaded to the ONOS Gerrit server.
Generate a key. Keep the default file name and location. This will generate an id_rsa and id_rsa.pub file in ~/.ssh:
- Upload the SSH public key. After logging into the Gerrit account, go to Settings > SSH Public Keys. Paste the contents of id_rsa.pub into the "Add SSH Public Key" box and hit Add:
Generate Password（only for https）
1、After logging into the Gerrit account, go to Settings > HTTP Password, click Generate Password to generate the password which using when submitting code, if you forget the password just go to HTTP Password regenerate a new one.
Developers planning to contribute code should configure git with their username and email.
