我正在尝试使用Ansible逐一重新启动我的docker容器以获取特定映像,但这似乎没有发生。以下是我的yml,它正在退出当前正在运行的容器。
---
- name: restart app servers
hosts: shashank-VM
connection: local
become: yes
become_method: sudo
tasks:
- name: Get info on the Container
shell: docker ps | awk '/{{ item }}/{print $1}'
register: list_of_containers
with_items:
- ubuntu
- name: Restart Docker Service
docker_container:
name: "{{ item }}"
# image: ubuntu
state: started
restart: yes
with_items: "{{ list_of_containers.results | map(attribute='stdout_lines') | list }}"
如果我在运行docker ps时看到以下输出,则没有正在运行的容器。

我在做什么错?有人可以帮忙吗?

我不认为docker_container
模块是按照您想要的方式设计的(例如,重新启动现有的容器)。该模块旨在按名称(而不是按ID)管理容器,并将检查正在运行的容器是否与提供给docker_container
的选项相匹配。
使用docker
命令重新启动容器可能会更好:

- name: restart app servers

become_method: sudo

shell: docker ps | awk '/{{ item }}/{print $1}'

command: docker restart {{ item }}
with_items: "{{ list_of_containers.results | map(attribute='stdout_lines') | list }}"
