6.2. Launch a pipeline
To launch a pipeline you need to have EXECUTE permissions for the pipeline. For more information see 13. Permissions.
Also you can launch a pipeline via CLI. See 14.5 Manage pipeline executions via CLI.
- Select a pipeline in the "Library" menu (3. Overview).
- Select a pipeline version to run.
- Click the Run button.
Launch pipeline page will be opened:
Feel free to change settings of run configuration if you need to. See an example of editing configuration here.
If the Price type is set as "On-demand" - at the Launch page, an additional checkbox Auto pause appears:
This checkbox allows to enable automatic pausing on-demand instance if it is not used. Such behavior could be controlled by Administrators using a set of parameters at System Preferences (see here).
Please note, this checkbox will not be displayed if any cluster is configured ("Static" or "Autoscaled").
If the Price type is set as "On-demand" - at the Launch page, an additional control Maintenance appears. It allows to configure schedule for automatical pause/resume a pipeline run. It could be useful when the pipeline is launched for a long time (several days/weeks) but it shall not stand idle, just increasing costs, in weekends and holidays, for example.
Schedule is defined as a list of rules (user is able to specify any number of them).
For each rule in the list the user is able to set:
- the action:
- the recurrence:
- Daily: every
- Weekly: every
- Daily: every
Conflicting rules are not allowed (i.e. rules that are configured on the same execution time).
If any schedule rule is configured for the launched active run - that run will be paused/restarted accordingly in the scheduled day and time.
To set a schedule for pause/restart a job:
- Click the Configure button:
- The "Maintenance" popup will appear:
- Click the Add rule button. The first rule will appear:
- Using available controls configure the rule according to your wish, e.g. to automatically pause a job every 2 days at
- To add another rule click the Add rule button. Configure a new rule using available controls, e.g. to automatically restart (resume) a job every monday and friday at
- Click the OK button to save specified rules
- Saved rules will be displayed at the Launch form:
Please note, the Maintenance control will not be displayed if any cluster is configured ("Static" or "Autoscaled").
Users (who have permissions to pause/resume a run) can create/view/modify/delete schedule rules anytime launched run is active via the Run logs page - for more details see 11. Manage runs.
- the action:
Please note, that the current user can launch a pipeline only if he/his group has corresponding permissions on that pipeline (for more information see 13. Permissions), but the Launch button may be disabled also for one of the following reasons:
executionisn't allowed for specified docker image;
readoperations aren't allowed for specified input or common path parameters;
writeoperations aren't allowed for specified output path parameters.
In such cases, hover over the Launch button to view warning notification with a reason of a run forbiddance, e.g.:
Note: you can also launch a pipeline with the same settings via the
To generate the corresponding command/request click the button near the "Launch" button. For more details see here.
Confirm launch in the appeared popup.
- You'll be redirected to the "Runs" area. Here you'll find your pipeline running. You can monitor status of your run and see additional information (see 11. Manage Runs).
Note: after some initialization time, a new node will appear in the "Cluster nodes" tab. See 9. Manage Cluster nodes.
Note: to learn about launching a pipeline as an Interactive service, refer to 15. Interactive services.
