在 Jenkins 容器中运行 ansible-playbook

Question

问题：是否可以有一个 docker-compose 文件在 Jenkins 容器中运行 ansible-playbook？

总结： 我有一个想要运行 ansible-playbook 的 Jenkins 容器（containerA）。但是，由于容器在执行后停止，我不知道如何在 docker-compose 中定义一个非运行容器。

我已经发布了docker ps -a、docker-compose 和ansible-playbook 的 Dockerfile 的输出

如果我的问题不清楚，请告诉我。 PG

仅当有任何进程或服务保持该容器运行时，docker 容器才会启动。

在您的 docker 文件中，您正在执行 ansible-playbook 命令，这将错误地指出 ERROR! You must specify a playbook file to run 以及帮助选项。

如果你想执行 ansible playbook，你必须传递更多参数

一个成功的剧本执行是这样发生的。

ansible-playbook -i <inventory_file> <playbook_name>
