我正在努力使用简单的 Web 文件部署 docker 容器，并编写了以下 Ansible 脚本，用于通过创建 docker 网络来配置和部署 docker 容器。我可以从网络访问 docker 容器，但无法管理将网站复制到容器。 以下是我的 Ansible 脚本和其他脚本。我尝试了不同的方法，但无法修复它。

这可以通过额外的步骤来完成，将内容从控制器 PC 复制到主机，然后挂载文件位置以进行文件部署。以下新任务已添加到 Ansible 中。
# copy the website to the host volume for deployment
- name: Create destination directory if it doesn't exist
ansible.builtin.file:
path: /tmp/nish-data
state: directory
- name: Copy files to Docker volume
ansible.builtin.copy:
src: "{{ playbook_dir }}/myweb"
dest: /tmp/nish-data
然后我们必须将volume属性添加到容器配置中。
# Defines the list of container configurations to add to the docker network
# In this case, second IP is automatically assign to the bridge network between
# docker host computer and the containers. this is a limitation.
- name: Define list of container configurations

volumes:

ports:
- "8080:80"

使用这种方法，网站文件将首先复制到主机 PC，然后部署。以下是 YML 文件的完整内容。
