zuul coordinates talking to multiple different systems via the concept of connections. A connection is listed in the zuul.conf file and is then referred to from the layout.yaml. This makes it possible to receive events from gerrit via one connection and post results from another connection that may report back as a different user.
Create a connection with gerrit.
Zuul will need access to a Gerrit user.
Create an SSH keypair for Zuul to use if there isn’t one already, and create a Gerrit user with that key:
cat ~/id_rsa.pub | ssh -p29418 gerrit.example.com gerrit create-account --ssh-key - --full-name Jenkins jenkins
Give that user whatever permissions will be needed on the projects you want Zuul to gate. For instance, you may want to grant Verified +/-1 and Submit to the user. Additional categories or values may be added to Gerrit. Zuul is very flexible and can take advantage of those.
Only one connection per a database is permitted.
- Database connection information in the form of a URI understood by sqlalchemy. eg http://docs.sqlalchemy.org/en/rel_1_0/core/engines.html#database-urls dburi=mysql://user:pass@localhost/db
