how can I use an environment variable in a parameter for a pipe?

[bradrust]

I am wanting to use the google-kubectl-pipe which takes numerous arguments which define the kubernetes cluster.

How can I use a variable as part of the variables/parameters for the pipe itself?

In the example below, I want the k8s_zone and k8s_cluster variables to be expanded before they are passed into the pipe.  In this cases, the pipe doesn't do any magic with variables and expected things to be static.

- echo ${k8s_zone}
- pipe: atlassian/google-gke-kubectl-run:1.1.2
  variables:
    KEY_FILE: 'gcloud-api-key.json'
    PROJECT: 'my-cluster-project'
    COMPUTE_ZONE: "${k8s_zone}"
    CLUSTER_NAME: "${k8s_cluster}"

Hi @bradrust . The code that you've shared should actually work just fine. Pipelines are expanding the variables before passing them to pipes. Maybe you could share more details about your issue with passing variables to the pipe?

Yes, I believe I was stuck on something else.   It appears that I was stuck on the correct way to pass the gcloud-api-key.json.   

thanks.
