Я борюсь с существующей ролью ansible MongoDB, которую я обновляю с помощью ansible -молекулы. Полная папка ролей, с задачами / файлами молекул, упрощена и загружена в gofile . Это можно скачать и смоделировать. Он не содержит вирусов, а md5sum: 6533724b40af534cc64ee0d6b9369943. Вот некоторые подробности о моей среде:
Python 3.8.2
ansible==2.9.10
ansible-lint==4.2.0
molecule==3.0.5
molecule-vagrant==0.3
pytest==5.4.3
testinfra==5.2.1
Я использую vagrant на VirtualBox, а целевыми ОС являются Ubuntu xenial и CentOS 7 для mon go 3.6 c установка:
bento/centos-7 (virtualbox, 202006.16.0)
bento/ubuntu-16.04 (virtualbox, 202002.04.0)
По сути, роль в целом смогла установить MongoDB в обеих операционных системах. Есть пара команд оболочки, чтобы проверить версию экземпляра, включить ли аутентификацию или это член набора реплик. Один из них выглядит следующим образом:
- name: Checking for mongo version
shell: >
`which mongo` --port {{ mongofamily_server_port | default(27017) }} --eval 'db.version()' $1 | grep 'MongoDB server version' | grep '[0-9]' -o | head -1
register: sreg_mongo_version_info
- debug: var=sreg_mongo_version_info
Результат ниже показывает, что это хорошо работает для centos, но не для ubuntu

Ручной тест на экземпляре ubuntu был выполнен с буквально дословно скопировать команду и все прошло успешно. Я тестировал обвинение в этом Ubuntu, поэтому я попробовал с debian jess ie, и результат был таким же: работает на centos, а не на debian, и работает из прямой командной строки. Так что я, в свою очередь, обвинил молекулу. Поэтому я создал тестовую папку с инвентарем для прямого запуска ansible на ubuntu, вызвав playbook test/outside_molecule_playbook.yml, но результат был таким же:
прямой ansible запускать на экземпляре ubuntu
На данный момент я действительно не уверен в том, что происходит, потому что это меня не устраивает. Я хотел узнать, есть ли у кого-нибудь из вас такой же опыт и как это было исправлено. Я действительно пытался добавить путь к среде в playbook, но это тоже не сработало. Плейбук уже хорошо работает без него для CentOS.
Так что прямо сейчас у меня нет идей, почему это происходит и как это исправить.
Заранее спасибо.

UPDATE 3
Я написал небольшой сценарий оболочки с именем check_mongo_version. sh в папке с файлами:
#!/bin/sh
$(which mongo) --port $1 --eval 'db.hostInfo()'
и задача становится:
- name: Checking for mongo version
script: "files/check_mongo_version.sh {{ mongofamily_server_port | default(27017) }}"
register: sreg_mongo_version_info
Ошибка такая же, как Error: couldn't connect to server 127.0.0.1:27017
