Gitlab CICD部署应用

部署设计

对于前后端服务都基于 Kubernetes 进行部署，有关 Kubernetes 安装可以参考： 附042.Kubernetes_v1.33.0生成环境高可用部署方案 。

后端 java 项目部署三套环境，即一套 CI 持续集成环境，一套测试环境，一套生产环境。
同时将每套环境部署在不同的 namespace 下，总体规划如下：

环境namespace
CI环境gitlabci
测试环境gitlabtest
生产环境gitlabprod

集成Kubernetes

当前 Gitlab 的 runner 是基于 helm 部署 gitla 的同时配套部署的，即 runner 是运行在 Kubernetes 中的一个 Pod，runner 类型是 Kubernetes ，如下所示：

root@master01:~# kubectl -n gitlab exec -ti mygitlab-gitlab-runner-798986f578-h2thf -- bash
camygitlab-gitlab-runner-798986f578-h2thf:/$ cat /home/gitlab-runner/.gitlab-runner/config.toml
#……
[[runners]]
#……executor = "kubernetes"

因此该 runner 后续需要直接在 Kubernetes 中部署业务，需要安装 kubectl 命令，以及配置 kubeconfig 上下文。

从而需要提前将 kubeconfig 内容以变量形式引入到 runner Pod 中。

root@master01:~# echo $(cat ~/.kube/config | base64) | tr -d " "
YXBpVmVyc2lvbjogdjEKY2x1c3RlcnM6Ci0gY2x1c3RlcjoKICA……

添加变量 KUBE_CONFIG 。

205

提示：由于后续流水线中作业有 main 和 tag 两种触发方式，因此建议将变量取消受保护。

后端Java项目部署

通过如下 yaml 进行部署。

创建gitlab部署项目

创建部署专用于部署后端 java 应用的 gitlab 项目。

204

创建部署文件

创建如下 ci 环境部署文件。

[root@gitclient ~]# git clone git@gitlab.linuxsb.com:mygroup/mydeployjava.git
