Parameter/ Environment Variable - List of values support

[Sarmistha Bhuyan]

I have a need to show user list of values from database and user can select any value as parameter value and trigger the pipeline. Is there a way to achieve this?

I don't think there is a clean way to achieve this to my knowledge.

The closest you could achieve that I can think of is some custom automation that

• periodically queries your database to get the allowed values you are referring to
  
• updates a pipeline's definition (via a configuration repository, or via the GoCD API) to
  
• pre-populate an environment variable with a dummy value to give the user a hint as to the valid values, e.g VAL-A|VAL-B|VALC
• at the same time automatically updates the pipeline's definition to add a first "script" task that validates the environment variable is set to one of the allowed options

If you need to use GoCD parameters and templates rather than environment variables, something similar could be done using those, perhaps.

Thanks Chad. 

We are trying to achieve this using  GoCD parameters and templates but not yet successful. We will try the workaround provided by you too.
