setup_ansible-target-node

ATTENTION: これは公開リポジトリです。

ansible-playbook の実行対象となる target node をセットアップするためのもの。 外部に公開したくなかったが、セットアップ処理の利便性の都合で公開している。

外部からのPR等は一切受け付ける予定はない。

Usage

## default (3.12)
curl -LsSf https://raw.githubusercontent.com/link-u/setup_ansible-target-node/refs/heads/main/install-uv-python4ansible.bash | bash -s

## 3.14
curl -LsSf https://raw.githubusercontent.com/link-u/setup_ansible-target-node/refs/heads/main/install-uv-python4ansible.bash | UV_PYTHON_VERSION=3.14 bash -s

## 実行例
root@test-target-u18:~# curl -LsSf https://raw.githubusercontent.com/link-u/setup_ansible-target-node/refs/heads/main/install-uv-python4ansible.bash | bash -s
root@test-target-u18:~# /usr/local/lib/python4ansible/venv/bin/python3 --version
Python 3.12.13

[all:vars]
ansible_python_interpreter="/usr/local/lib/python4ansible/venv/bin/python3"

ただし、pip module の venv 環境への対応は、各role毎に必要。

Purpose

古い OS だと、最新版の ansible を使うために必要な python version が不足するため。 様々な version の OS で ansible-playbook を安定して利用するためには、

• Ansible のサポート
  • https://docs.ansible.com/projects/ansible/latest/reference_appendices/release_and_maintenance.html
• uv のサポート https://docs.astral.sh/uv/reference/policies/platforms/#linux-versions

Ubuntu 毎の glibc は以下の通り。

$ for i in u{16,18,20,22,24}; do echo -n "[$i]: "; lxc exec test-target-$i -- ldd --version | grep GLIBC; done
[u16]: ldd (Ubuntu GLIBC 2.23-0ubuntu11.3) 2.23
[u18]: ldd (Ubuntu GLIBC 2.27-3ubuntu1.6) 2.27
[u20]: ldd (Ubuntu GLIBC 2.31-0ubuntu9.18) 2.31
[u22]: ldd (Ubuntu GLIBC 2.35-0ubuntu3.13) 2.35
[u24]: ldd (Ubuntu GLIBC 2.39-0ubuntu8.7) 2.39

また、uv はきちんと glibc に対応した python binary をインストールしていた。

root@test-target-u16:~# for i in {10..14}; do uv venv --python "3.${i}" "py3${i}"; done
root@test-target-u16:~# for i in {10..14}; do pushd  "py3$i"; uv pip install packaging; popd; done

root@test-target-u16:~# for i in {10..14}; do "py3$i/bin/python3" -c "import platform; print(platform.libc_ver())"; done
