Summary

Let's say the user has an external script to do some deployment work. The user calls the script in the script section of the pipeline as below:

pipelines:
  default:
    - step:
        script:
          - ./script.sh

In the script, they want to export some variables to use in other commands within the same step in Bitbucket Pipelines.

Here is an example of the script content:

#!/bin/bash

export TEST_VARIABLE='Test variable.'

Environment

Bitbucket Pipelines

Diagnosis

In this scenario, if the user tries to use $TEST_VARIABLE outside the script it won't work. Example:

pipelines:
  default:
    - step:
        script:
          - ./ script.sh
		  - echo $TEST_VARIABLE	

Cause

To have those variables available, the script must be executed in the context of the calling shell.

Solution

Do not call the script with the "./" syntax, use one of the following options instead:

. script.sh

or

source script.sh

Example of a working Pipeline for this scenario:

pipelines:
  default:
    - step:
        script:
          - source script.sh
		  - echo $TEST_VARIABLE
