在Jenkins容器中运行ansible剧本

Question

问题：有可能让一个docker compose文件在Jenkins容器中运行ansible playbook吗？

摘要：我有一个Jenkins容器(containerA(，我想运行一个可靠的剧本。然而，由于容器在执行后停止，我不知道如何在docker compose中定义一个未运行的容器。

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

如果我的问题不清楚，请告诉我。PG

只有当有任何进程或服务要运行docker容器时，该容器才会启动。

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和帮助选项。

如果你想执行易出错的剧本，你必须传递更多的参数

一个成功的剧本执行是这样的。

ansible-playbook -i <inventory_file> <playbook_name>
