前言
很久之前、部署方案选择了基于 Docker 的容器化落地方案，极简描述与总结于 gogs_drone_docker。但是随着微服务抽象定义的服务越来越多、团队规模越来越壮大时，单机部署的自动化持续部署平台在并行处理任务可能会出现大量排队、扩容机制不灵活，同时为了统一、对齐部署姿势，因此将 Docker 转 Kubernetes 。
目的
拥抱云原生的敏捷开发姿势，践行持续集成 / 持续部署，标准化工作流程，自动化执行流程步骤，从而提升能效和质量。

组件
此方案的组件选型并非唯一的选择，以自动化构建 Drone 作为基准，其它组件的选择是灵活可变的，每个组件支持丰富的选择，比如代码协作工具支持 Gitlab、Gogs等，数据库支持SQLite、MySQL、Postgres等

部署
前置说明
- 持久化后端存储使用阿里云的
NAS -
VirtualService.yaml为阿里云网格服务的虚拟服务编排定义，根据实际情况而定，常见Ingress、Traefik... - 此方案上部分应用依赖
postgres，因便于调试采取容器化部署(生产上不推荐) - 计划后续将支持
helm部署
部署步骤
⚠️因为环境、配置、后端存储、调度策略等不一致，需要自定修改编排文件
创建命名空间
➜ kubectl create namespace devops
创建节点标签
➜ kubectl label nodes ${cicd_node} cicd=true
创建节点污点
➜ kubectl taint nodes ${cicd_node} operation=cicd:NoSchedule
部署组件应用
# 部署数据库依赖.postgres
kubectl apply -f postgres
# 部署代码协作工具git.gogs
kubectl apply -f gogs
# 部署自动化构建工具dorne
kubectl apply -f drone/server
kubectl apply -f drone/runner
# 部署代码质量检测工具
kubectl apply -f sonarqube
运行
