Summary
The x2a-convertor generates an Ansible task that uses ansible.builtin.command with shell operators (||, &&, multi-line commands), which causes the task to fail at runtime. The command module does not pass arguments through a shell, so operators like || and && are interpreted as literal arguments.
Steps to Reproduce
- Run x2a-convertor against the fastapi-tutorial Chef cookbook (source: https://github.com/x2ansible/chef-examples.git)
- Publish the generated Ansible code to GitHub
- Run the generated playbook against any target (e.g., Ubuntu 20.04 container)
Expected Result
The generated Ansible playbook runs successfully end-to-end.
Actual Result
The playbook fails at the "Create PostgreSQL user and database" task with:
fatal: [x2ansible-test-37]: FAILED! => {"msg": "non-zero return code", "rc": 1, "stderr": "/usr/lib/postgresql/12/bin/psql: invalid option -- 'u'"}
The generated task in roles/fastapi_tutorial_build_37/tasks/main.yml (line 41) is:
- name: Create PostgreSQL database and user ansible.builtin.command: cmd: 'sudo -u postgres psql -c "CREATE USER ..." || true sudo -u postgres psql -c "CREATE DATABASE ..." || true sudo -u postgres psql -c "GRANT ALL PRIVILEGES ..." || true' changed_when: false
Root Cause
ansible.builtin.command does NOT invoke a shell. It splits the cmd string on whitespace and passes each token as a positional argument. The ||, &&, and multi-line chaining are shell constructs that only work with ansible.builtin.shell.
Suggested Fix
Either:
- Use ansible.builtin.shell instead of ansible.builtin.command when the task requires shell operators
- Or split the task into three separate ansible.builtin.command tasks (one per SQL statement)
- Or use the community.postgresql.postgresql_user and community.postgresql.postgresql_db modules directly (best practice)
