How do I pin a docker image? pip install virtualenv started failing on google/cloud-sdk latest

Running “pip install virtualenv” as part of our build_environments step started throwing and error[1] two days ago, which coincided with a new google/cloud-sdk image release[2]. How do I pin an image version, so I can test it’s an issue with the latest image? Here is the docker setup:

docker:
  - image: google/cloud-sdk
    auth:
      username: <redacted>
      password: <redacted>

and here is the build_environment step that’s failing on the first command:

  - run:
      name: build_environment
      command: |
        pip install virtualenv
        virtualenv Venv
        source Venv/bin/activate
        pip install -r requirements-dev.txt -r requirements.txt

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.
    
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    
    See /usr/share/doc/python3.11/README.venv for more information.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

I mitigated the issue by switching from pip to apt-get to manage virtualenv.
