Connections

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.

Gerrit

Create a connection with gerrit.

driver=gerrit

server

FQDN of Gerrit server. server=review.example.com

port

Optional: Gerrit server port. port=29418

baseurl

Optional: path to Gerrit web interface. Defaults to https://<value of server>/. baseurl=https://review.example.com/review_site/

user

User name to use when logging into above server via ssh. user=zuul

sshkey

Path to SSH key to use when logging into above server. sshkey=/home/zuul/.ssh/id_rsa

keepalive

Optional: Keepalive timeout, 0 means no keepalive. keepalive=60

Gerrit Configuration

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.

SMTP

driver=smtp

server

SMTP server hostname or address to use. server=localhost

port

Optional: SMTP server port. port=25

default_from

Who the email should appear to be sent from when emailing the report. This can be overridden by individual pipelines. default_from=zuul@example.com

default_to

Who the report should be emailed to by default. This can be overridden by individual pipelines. default_to=you@example.com

SQL

Only one connection per a database is permitted.

driver=sql

dburi

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
