ansible deploy docker-compose services

Install Ansible

python3 -m venv ./venv
./venv/bin/python3 -m pip install ansible
export PATH="`pwd`/venv/bin:$PATH"
ansible-inventory -i inventory.yaml --list
ansible virtualmachines -m ping -i inventory.yaml

create files

目录结构如下

roles
├── common
│   └── tasks
│       └── main.yaml
└── nginx
    ├── files
    │   ├── conf.d
    │   │   ├── forbidden.conf
    │   │   ├── jdk8-api.dev.conf
    │   │   └── status.conf
    │   └── docker-compose.yml
    └── tasks
        └── main.yaml
site.yaml
inventory.yaml

inventory.yaml 填写 vm 分组信息

tool_vms:
  hosts:
    tool:
      ansible_host: ip/hostname

site.yaml

---
- name: Deploy to tool nodes
  hosts: tool_vms
  roles:
    - nginx

roles 编写具体步骤

files 放用到的文件，tasks 放具体的任务

common/tasks/main.yaml

- name: "Set variables"
  set_fact:
    path: "/opt/projects/nginx"

- name: Create Folder
  file:
    path: "{{ path }}"
    state: directory

- name: copy Docker Compose and nginx conf files
  copy:
    src: files/{{ item }}
    dest: "{{ path }}/{{ item }}"
  loop:
    - conf.d/
    - docker-compose.yml
