christiangda.amazon_cloudwatch_agent

Ansible 角色:christiangda.amazon_cloudwatch_agent

主分支工作流 开发分支工作流 Ansible 角色

这个角色用于安装 AWS CloudWatch Agent

安装此角色的最好方法是使用命令 ansible-galaxy install christiangda.amazon_cloudwatch_agent,Ansible Galaxy 存储库为christiangda.amazon_cloudwatch_agent

存储库代码可在https://github.com/christiangda/ansible-role-amazon-cloudwatch-agent

特性:

  • 适用于 AWS EC2 实例本地实例
  • 支持不同版本的 Python、Ansible 和操作系统(更多详情请参见 持续集成矩阵
  • AWS 发行包 下载并安装 CloudWatch Agent
  • 当配置更改时重新加载服务
  • 提供默认的 代理配置 文件(这是一个最小配置,不推荐使用)
  • 旋转 CloudWatch Agent 日志文件
  • 允许您加载自定义的 JSON 文件 / YAML 文件或内嵌配置,适用于代理、指标和日志部分
  • 支持 amd64arm64 架构

注意事项:

克隆角色存储库(从您的分叉)并创建符号链接

注意:首先分叉主存储库。

git clone https://github.com/<你的 GitHub 用户>/ansible-role-amazon-cloudwatch-agent.git
ln -s ansible-role-amazon-cloudwatch-agent christiangda.amazon_cloudwatch_agent
cd christiangda.amazon_cloudwatch_agent

执行分子测试

可用场景:

  • default --> --driver-name docker
  • podman --> --driver-name podman
  • vagrant --> --driver-name vagrant

默认场景

逐步执行

molecule create [--scenario-name default]
molecule converge [--scenario-name default]
molecule verify [--scenario-name default]
molecule destroy [--scenario-name default]

或全都一起执行

molecule test [--scenario-name default]

podman 场景

逐步执行

molecule create --scenario-name podman
molecule converge --scenario-name podman
molecule verify --scenario-name podman
molecule destroy --scenario-name podman

或全都一起执行

molecule test --scenario-name podman

vagrant 场景

逐步执行

molecule create --scenario-name vagrant
molecule converge --scenario-name vagrant
molecule verify --scenario-name vagrant
molecule destroy --scenario-name vagrant

或全都一起执行

molecule test --scenario-name vagrant

此外,如果您想使用虚拟机进行测试,我有一个非常好的 ansible-playground 项目,使用 Vagrant 和 VirtualBox,建议试试!
