Example: servers.yaml (json example here)

---
aws: # Group name that can contain multiple hosts configuration
  - name: aws # Identification name
    host: domain.aws.com
    port: 2020
    username: root
    password: "123456"
    identityFile: "./aws-key.pem"

homelab:
  - name: raspberry-pi1
    host: 192.168.1.70
    port: 2020
    username: syncr
    password: "123456"

  - name: raspberry-pi2
    host: 192.168.1.71
    port: 2020
    username: syncr
    password: "123456"

Scenarios

A scenario have a set of tasks that will be executed, in order, in the specified groups of hosts (see server configuration).

Scenarios configuration file

The scenario configuration file can contain one or multiple scenarios, defined as an array.

Example with command, upload file and execute script: script-and-file.scenario.yaml (json example here)

---
- name: Execute script and upload file example
  hosts:
    - homelab
    - dev
  tasks:
    - name: Upload file
      uploadFile: ../scripts/file-to-upload.txt
      mode: 0o600
    - name: Execute script # optional
      script: ../scripts/example.sh
    - command: ls -lh

Note¹: hosts can contain the value all to execute in all enabled hosts from all groups in servers config file;
Note²: The uploadFile and script file paths are relative to the scenario file.
