The runners page

The list of runners, adding one, and the default of each type

The page under Connections > Runners lists every runner with these columns:

Column Meaning
Default Whether it is the default runner of its type.
Name How forms refer to it, with runner: <name>.
Registration How it was added; see Registration.
Type Runtime environment (RTE), AWX, Ansible Automation Platform, Ascender, Semaphore UI, Rundeck or Jenkins.
Uri Its address.

Add runner opens a dialog in four steps: Runner (name and description), Type, Connection and Authentication. A row opens the runner’s own page, and its menu offers Edit runner, Test connection, Change authentication and Delete runner.

Edit defaults opens a dialog with the default runner of each type:

Group Where these forms run when they name no runner
Playbook forms ansible forms, on an RTE
AWX, AAP and Ascender forms awx, aap and ascender forms, on an AWX runner
Semaphore forms semaphore forms
Rundeck forms rundeck forms
Jenkins forms jenkins forms

The first runner of a type becomes its default, so a single runner per type needs no extra step.
