How to use override values?
Asked by ???:

I will use the two steps for 'mainnet-detach', 'mainnet-attach' twice in pipelines.custom.

In the same code(mainnet-detach / mainnet-attach), when the "deploy-mainnet" step is executed for the first time, the variable 'instance_target' is defined as API01, and when the step is executed the second time, the variable 'instance_target' is defined and executed as API02.

How should I modify my code to set the variables?

Currently, Bitbucket Pipelines does not support using variables to specify the runner's labels in the step definition. We do have an existing feature request for it at :

* <https://jira.atlassian.com/browse/BCLOUD-21510>

We suggest you **Vote** for that feature so that our product managers better understand the interest, and you can also add yourself as a **Watcher** to get notified whenever there's any update on that feature.

In the meantime, you will need to define two different steps where in each step you explicitly provide the runner label in the **runs-on**parameter, without using variables.

Thank you, [@???](/t5/user/viewprofilepage/user-id/5348328) !
