I use following module: 我使用以下模块：
https://docs.ansible.com/ansible/latest/modules/docker_service_module.html?highlight=ansible%20doc https://docs.ansible.com/ansible/latest/modules/docker_service_module.html?highlight=ansible%20doc

I can create and start docker container using this module. 我可以使用此模块创建和启动Docker容器。 However, is it possible to execute tasks (and preserve changes) on this container? 但是，是否可以在此容器上执行任务（并保留更改）？
I mean: 我的意思是：
install some yum package 安装一些yum包
insert some bash script into container. 在容器中插入一些bash脚本。

Could you give me some clues? 你能给我一些线索吗？

As a general rule, you don't install software on a running container. 通常，不要在正在运行的容器上安装软件。 If you need a container with some software installed in it, you should build a custom image that has the software you need, and set it up so that it can do everything it needs on its own once you start it up once. 如果您需要一个装有某些软件的容器，则应构建一个具有所需软件的自定义映像，并进行设置，以便一旦启动它即可自行完成所需的一切。 (As an even broader rule, you shouldn't need to docker exec into a running container except to debug things; it definitely isn't part of the core "how to do things with containers" workflow.) （作为一个更广泛的规则，除了调试之外，您无需将docker exec放入正在运行的容器中；它绝对不是核心的“如何对容器进行操作”工作流的一部分。）

I would recommend following a standard Docker tutorial, such as Docker's official tutorial on building and running custom images . 我建议遵循标准的Docker教程，例如有关构建和运行自定义映像的 Docker 官方教程。 Once you have a working Docker image workflow, you'd use the Ansible docker_container module in place of the docker run command. 拥有可用的Docker映像工作流程后，您将使用Ansible docker_container模块代替docker_container docker run命令。
