Running into error building an EE

[duetpupiahs]

Hello, I'm trying to build an EE with the Ansible Builder. My configuration looks like this:

execution-environment.yml

---
version: 3
images:
  base_image:
    name: 'quay.io/centos/centos:stream9'
dependencies:
  ansible_core:
    package_pip: ansible-core>=2.16,<2.17
  ansible_runner:
    package_pip: ansible-runner
  galaxy: requirements.yml
  python: requirements.txt
  system: bindep.txt
additional_build_steps:
  prepend_base:
    - RUN python3 -V
  append_base:
    - RUN $PYCMD -m pip install -U pip
  append_final:
    […]

requirements.txt

python>=3.10
pip>=24.2
[…]

Installed versions in venv:

Ansible-builder 3.1.0
Python 3.12.4
Pip 23.3.2

When I run "ansible-builder build --tag test.org/test-docker/test-ee:$container_tag --context context --verbosity 3" via a Pipeline it starts normally, but runs into an ERROR and a WARNING:

[1/4] STEP 16/20: RUN $PYCMD -m pip install --no-cache-dir $ANSIBLE_INSTALL_REFS

It seems like it doesn't matter what's installed in the venv since the ansible-builder installs its own packages. The "RUN python3 -V" command prepended to the base step returns "Python 3.9.19"

Is there anything I'm missing?

Thanks in advance!

ansible-core 2.16 requires a minimum of Python 3.10, as such, pip cannot find a version of core between 2.16 and 2.17 that will install on Python 3.9.

You can add the following to your EE definition to utilize a newer python:

dependencies:
+ python_interpreter:
+   package_system: python3.12
  ansible_core:
    package_pip: ansible-core>=2.16,<2.17
  ansible_runner:
    package_pip: ansible-runner

Thanks for the reply!

Unfortunately it doesn't help. I added the lines, ran it again and can see that Pyton 3.12 and dependencies are being installed, but the error remains the same.

That's my fault, I forgot another line:

dependencies:
+ python_interpreter:
+   package_system: python3.12
+   python_path: /usr/bin/python3.12
  ansible_core:
    package_pip: ansible-core>=2.16,<2.17
  ansible_runner:
    package_pip: ansible-runner

However, you probably also want to make this change as well, unless you remove your debugging line completely:

---
version: 3
images:
  base_image:
    name: 'quay.io/centos/centos:stream9'
dependencies:
+ python_interpreter:
+   package_system: python3.12
+   python_path: /usr/bin/python3.12
  ansible_core:
    package_pip: ansible-core>=2.16,<2.17
  ansible_runner:
    package_pip: ansible-runner
  galaxy: requirements.yml
  python: requirements.txt
  system: bindep.txt
additional_build_steps:
- prepend_base:
-   - RUN python3 -V
  append_base:
+   - RUN $PYCMD -V
    - RUN $PYCMD -m pip install -U pip
  append_final:
    […]

Thanks again! This seems to work. When I add the code Python3.12 gets installed. But I then run into the error:

[1/4] STEP 15/16: RUN $PYCMD -m pip install --no-cache-dir $ANSIBLE_INSTALL_REFS
/usr/bin/python3.12: No module named pip
subprocess exited with status 1
subprocess exited with status 1

It still seems to be within the first step of the builder, so I thought adding the command to "prepend_base" would result in it working:

additional_build_steps:
  prepend_base:
    - RUN $PYCMD -V
    - RUN $PYCMD -m pip install -U pip

But then I get this error:

[1/4] STEP 14/18: RUN $PYCMD -V
/bin/sh: line 1: /usr/bin/python3.12: No such file or directory
subprocess exited with status 127
subprocess exited with status 127

If I remove everything in "prepend_base" and "append_base" it works. Thanks again for your help.

Looks like this was resolved. Closing.
