How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub with version 37.183.1

Please tell us more about your question or problem

I am trying to update the Changelog using postUpgradeTasks for every new Renovate PR. For that, I want to be able to execute a bash or Python script, since the version calculation and positioning has some complexity, but I am encountering some issues:

• executing a Python script using Poetry - any Python or Poetry command I am getting the error

Command failed: poetry --version
/bin/sh: 1: poetry: not found

or

Command failed: python --version
/bin/sh: 1: python: not found

• using a bash script - I don't want to have the same script in every repo so I need to be able to download it from somewhere

My package rule is:

{
      "postUpgradeTasks": {
        "commands": [
          "echo \"test\" >> CHANGELOG.md",
          "poetry --version"
        ],
        "executionMode": "branch"
      },
      "matchManagers": ["poetry"]
}

We use the slim Docker image and binarySource is set to the default install.

I don't fully understand how containerbase works, but from my understanding Poetry should be installed and available at runtime.

Do you have any hints on what could be the issue here? Or do you think this can be achieved in any other way?

If you run your script only after Renovate updates lock files, it should already be installed. If not, run install-tool poetry x.y.z yourself as part of your script. Alternatively, use the full image which has every manager pre-installed.

This was a great hint, now I understand why I don't have Poetry or Python installed, because the repo does not have a lock file since this project is a Python package and does not need one, only for testing. This means that instructions like

DEBUG: Executing command (repository=Bot/renovate-testing.7IYlBR, branch=renovate/my-package)
       "command": "install-tool poetry 1.8.2"

Are not executed during the upgrade.

This also means that I need to install it explicitly both Python and Poetry with something like:

{
      "postUpgradeTasks": {
        "commands": [
          "install-tool python 3.11.9",
          "install-tool poetry 1.8.2",
          "echo \"test\" >> CHANGELOG.md",
          "poetry --version"
        ],
        "executionMode": "branch"
      },
      "matchManagers": ["poetry"]
}

This works as expected, however, I would have to add some logic to understand which version of Python to use.

Thanks a lot for the quick response, this already helps me a lot.

By the way, you should update. Your version was released on the 12th of February. That's nearly three months old.

[CCardosoDev]

Yes, we are in the process of doing so.
