在 Jenkins 容器中运行 ansible-playbook

Question

问题：是否可以使用 docker-compose 文件在 Jenkins 容器中运行 ansible-playbook？

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

我已经发布了 docker docker ps -a的输出，docker docker-compose和 ansible 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让该容器运行时，docker 容器才会启动。

在您的 docker 文件中，您正在执行ansible-playbook命令，这将显示ERROR! You must specify a playbook file to run ERROR! You must specify a playbook file to run与帮助选项一起ERROR! You must specify a playbook file to run 。

如果要执行 ansible playbook，则必须传递更多参数

成功的剧本执行就像这样。

ansible-playbook -i <inventory_file> <playbook_name>
