This is a Github action that sets environment variables for a Job in a workflow.

The action has a required input called envFile. This sets the path to the file containing the environment variables to set for e.g. staging.env.

This action reads all variable defined in a file and makes them available as environment variables to the workflow steps. In the above example, variables defined in staging.env will be setup as environment varaibles.

1. Use the checked out action in your workflow:

   - name: Set staging env vars
     uses: university-of-york/ds-devtool-setEnvVars@v1
     with:
       envFile: 'staging.env'
   

Any secrets defined as environment variables when using action are setup as environment variables to the steps in the workflow. This does not reveal the value of the secret. An example of using secrets is as follows:

    - name: Set staging env vars
      uses: university-of-york/ds-devtool-setEnvVars@v1
      with:
        envFile: 'staging.env'
      env:
          MY_SECRET: ${{secrets.MY_SECRET}}

The secret can then be used in the workflow steps as $MY_SECRET.

By default, this action will not replace environment variables that have been previously defined. You may change this by setting the overwrite flag:

    - name: Set staging env vars
      uses: university-of-york/ds-devtool-setEnvVars@v1
      with:
        envFile: 'staging.env'
        overwrite: true
      env:
          MY_SECRET: ${{secrets.MY_SECRET}}
