Hi folks! I'm using poetry to manage the deps of my pulumi deployment script. When I use the Pulumi Github action, I have to install the deps via pip, though, and a generated

requirements.txt

file. A workflow like this runs: https://github.com/pulumi/actions/blob/master/examples/python-pulumi.yaml But I would like to do something like this:

- id: "setup-python-pulumi"
        name: "Install Pulumi Python environment"
        uses: actions/setup-python@v3
        with:
          python-version: '3.10'
      
      - id: "get-deployment-deps"
        name: "Get deployment script deps"
        working-directory: iac
        run: |
          pipx install poetry
          poetry install

      - id: 'pulumi-deploy'
        name: 'Deploy from Pulumi IaC'
        uses: pulumi/actions@v3
        with:
          command: up
          stack-name: nocap/dev
          work-dir: iac
          refresh: true

However, the Pulumi action fails, saying it can't import pulumi. It doesn't use the environment Poetry created. Is there a way to specify your environment to the action?

+ 1! AFAIK it’s only possible to specify which environment pulumi runs in in the Pulumi.yaml file which is project wide and static. It would be really handy to be able to specify which environment the stack runs in at runtime. I’ve tried overriding the runtime.options.virtualenv property for the stack since we can do that via the CLI during runtime but that didn’t get picked up.

I have this configured:

poetry config virtualenvs.in-project true

which creates the virtual environment folder within the project setup. With that in place, you can use Poetry to manage dependencies, then run Pulumi with the

venv

folder configured in

Pulumi.yaml

.

Ah, that makes sense @limited-rainbow-51650. thanks! That got me working. I changed my Pulumi.yaml file to include:

runtime:
  name: python
  options:
    virtualenv: venv

And ran

poetry config virtualenvs.in-project true --local

(just setting it for this project) and made sure

poetry.toml

was added to source control.
