Can you associate a mistral workflow execution with an environment via the CLI?

I can create an environment, and I can create a workflow execution. But I don't see any way via the CLI to associate a workflow or a workflow execution with an environment

usage: mistral environment-create [-h] [-f {json,shell,table,value,yaml}]
                              [-c COLUMN] [--max-width <integer>]
                              [--print-empty] [--noindent]
                              [--prefix PREFIX]
                              file

usage: mistral workflow-create [-h] [-f {csv,json,table,value,yaml}]
                           [-c COLUMN] [--max-width <integer>]
                           [--print-empty] [--noindent]
                           [--quote {all,minimal,none,nonnumeric}]
                           [--public]
                           definition

                            [-c COLUMN] [--max-width <integer>]
                            [--print-empty] [--noindent] [--prefix PREFIX]
                            [-d DESCRIPTION]

I don't think there is a way to link a pre-existing environment. You could, however, have a task in the workflow that fetches the environment. This workflow takes the name of a environment, it then fetches it and outputs the contents of the environment.

wf:
  input:
    - env_name
  tasks:
    get_env:
      action: mistral.environments_get name=<% $.env_name %>
      publish:
        env: task(get_env).result.variables
      on-complete: do_something
    do_something:
      action: std.echo output=<% $.env %>

Thanks. I guess I don't understand when the pre-existing environments are ever used then.

When you define an environment inline, you pass it with the "env" key as part of the [params] argument (which is in JSON format IIUC). I'm not sure how that applies to predefined environments created through the API though.

Thanks! This solves my problem.
