how to use same environement varibale in multiple steps in bitbucket pipelines - bitbucket

Question

Below script giving an error
The deployment environment 'staging' in your bitbucket-pipelines.yml file occurs multiple times in the pipeline. Please refer to our documentation for valid environments and their ordering.
image: python:3.8
options:
docker: true
pipelines:
branches:
master:
- step:
deployment: staging
name: Setup stage
script:
- echo ${db_name}
- step:
deployment: staging
name: Setup cli prod
script:
- echo ${db_name}
- step:
deployment: staging
name: Setup cli sandbox
script:
- echo ${db_name}
I want to use same environment variable (staging) in all steps of my pipeline. Please guide me how to do this.

Answer 1

This can't be done because steps marked as deployments must be unique.
Deployment variables are those needed to deploy the VCS to a particular deployment stage. If you are setting up administrative tasks as pipelines, those are NOT deployments.
Or if those are actual deployments, abide by the error message you are getting and make sure the declared deployment stage is unique:
image: python:3.8
options:
docker: true
definitions:
yaml-anchors:
- &deploy-step
script:
- echo ${db_name}
pipelines:
branches:
master:
- step:
<<: *deploy-step
deployment: staging
name: Deploy staging
- step:
<<: *deploy-step
deployment: production
name: Deploy prod
- step:
deployment: sandbox
name: Deploy sandbox
