Privileged commands

Some commands require a valid authentication token to be passed as the --auth-token argument. Administrators can generate such a token for users as needed.

Usage

The general options that apply to all subcommands are:

zuul-client --help

The following subcommands are supported:

Autohold

Note

This command is only available with a valid authentication token.

zuul-client autohold --help

Example:

zuul-client autohold --tenant openstack --project example_project --job example_job --reason "reason text" --count 1

Autohold Delete

Note

This command is only available with a valid authentication token.

zuul-client autohold-delete --help

Example:

zuul-client autohold-delete --tenant openstack --id 0000000123

Autohold Info

zuul-client autohold-info --help

Example:

zuul-client autohold-info --tenant openstack --id 0000000123

Autohold List

zuul-client autohold-list --help

Example:

zuul-client autohold-list --tenant openstack

Dequeue

Note

This command is only available with a valid authentication token.

zuul-client dequeue --help

Examples:

zuul-client dequeue --tenant openstack --pipeline check --project example_project --change 5,1
zuul-client dequeue --tenant openstack --pipeline periodic --project example_project --ref refs/heads/master

Enqueue

Note

This command is only available with a valid authentication token.

zuul-client enqueue --help

Example:

zuul-client enqueue --tenant openstack --trigger gerrit --pipeline check --project example_project --change 12345,1

Note that the format of change id is <number>,<patchset>.

Enqueue-ref

Note

This command is only available with a valid authentication token.

zuul-client enqueue-ref --help

This command is provided to manually simulate a trigger from an external source. It can be useful for testing or replaying a trigger that is difficult or impossible to recreate at the source. The arguments to enqueue-ref will vary depending on the source and type of trigger. Some familiarity with the arguments emitted by gerrit update hooks such as patchset-created and ref-updated is recommended. Some examples of common operations are provided below.

Manual enqueue examples

It is common to have a release pipeline that listens for new tags coming from gerrit and performs a range of code packaging jobs. If there is an unexpected issue in the release jobs, the same tag can not be recreated in gerrit and the user must either tag a new release or request a manual re-triggering of the jobs. To re-trigger the jobs, pass the failed tag as the ref argument and set newrev to the change associated with the tag in the project repository (i.e. what you see from git show X.Y.Z):

zuul-client enqueue-ref --tenant openstack --trigger gerrit --pipeline release --project openstack/example_project --ref refs/tags/X.Y.Z --newrev abc123...

The command can also be used asynchronosly trigger a job in a periodic pipeline that would usually be run at a specific time by the timer driver. For example, the following command would trigger the periodic jobs against the current master branch top-of-tree for a project:

zuul-client enqueue-ref --tenant openstack --trigger timer --pipeline periodic --project openstack/example_project --ref refs/heads/master

Another common pipeline is a post queue listening for gerrit merge results. Triggering here is slightly more complicated as you wish to recreate the full ref-updated event from gerrit. For a new commit on master, the gerrit ref-updated trigger expresses "reset refs/heads/master for the project from oldrev to newrev" (newrev being the committed change). Thus to replay the event, you could git log in the project and take the current HEAD and the prior change, then enqueue the event:

NEW_REF=$(git rev-parse HEAD)
OLD_REF=$(git rev-parse HEAD~1)

zuul-client enqueue-ref --tenant openstack --trigger gerrit --pipeline post --project openstack/example_project --ref refs/heads/master --newrev $NEW_REF --oldrev $OLD_REF

Note that zero values for oldrev and newrev can indicate branch creation and deletion; the source code of Zuul is the best reference for these more advanced operations.

Promote

Note

This command is only available with a valid authentication token.

zuul-client promote --help

This command will push the listed changes at the top of the chosen pipeline.

Example:

zuul-client promote --tenant openstack --pipeline check --changes 12345,1 13336,3

Note that the format of changes id is <number>,<patchset>.

The promote action is used to reorder the change queue in a pipeline, by putting the provided changes at the top of the queue; therefore this action makes the most sense when performed against a dependent pipeline.

The most common use case for the promote action is the need to merge an urgent fix when the gate pipeline has already several patches queued ahead. This is especially needed if there is concern that one or more changes ahead in the queue may fail, thus increasing the time to land for the fix; or concern that the fix may not pass validation if applied on top of the current patch queue in the gate.

If the queue of a dependent pipeline is targeted by the promote, all the ongoing jobs in that queue will be canceled and restarted on top of the promoted changes.
