Jenkins ansible plugin не может найти исполняемый файл

Question

Я запускаю Jenkins на Amazon EC2 - мастер в контейнере Docker и агент на отдельной коробке. Моя playbook выполняет сценарий Ansible, используя плагин Jenkins Ansible.

Мне пришлось установить новую версию Ansible на агента. Я установил Ansible из git, используя инструкции Running from Source, и установлен на /home/ec2-user/ansible. Если я передаю ssh агенту и запустил which ansible, я получаю ~/ansible/bin/ansible, как и ожидалось. Я ввел /home/ec2-user/ansible/bin в «Ansible executables directory» для моей новой установки на странице «Управление инструментами Jenkins> Global Tool Configuration».

Когда я запускаю мой трубопровод Дженкинс, однако, я получаю это:

Running on docker-agent-1 in /home/ec2-user/jenkins/workspace/planet-healthcare-pipeline 
[Pipeline] { 
[Pipeline] pwd 
[Pipeline] stage 
[Pipeline] { (Download source and capture commit ID) 
[Pipeline] sh 
[planet-healthcare-pipeline] Running shell script 
+ which ansible 
which: no ansible in (/usr/local/bin:/bin:/usr/bin) 

Он говорит, что это работает на docker-agent-1 (это имя моего агента), и я могу видеть анзибль если я SSH там. Почему Дженкинс не может найти исполняемый файл?

UPDATE: После добавления PATH в качестве переменной окружения, он может найти Ansible, но теперь что-то еще ломается. Вот новый выход:

} 

Это неудачу в стадии «Run тестовый набор» - он не может найти rails запустить rails db:migrate, хотя я знаю, он находится в контейнере.

Почему настройка PATH на агенте влияет на скрипт, который происходит внутри контейнера Docker?

Answer 1

Вы выполняете which ansible в своем скрипте? Он ищет только определенные PATH.
И кажется /home/ec2-user/ansible/bin нет в /usr/local/bin:/bin:/usr/bin (с вашего выхода).
Вы можете перейти к настройкам агента-агента в Jenkins и добавить переменную окружения PATH с значением $PATH:/home/ec2-user/ansible/bin.
