本编博客是继[gitlab cicd (三)系列之安装git-runner docker安装方式][gitlab cicd _git-runner docker]安装方式之后另一种安装gitlab-runner的安装方式—kubernetes安装方式

kubernetes集群的安装  
请参考[kubernetes v1.11.0 从代码编译到部署文档-部署][kubernetes v1.11.0 _-]

kubernetes版本

[root@master-47-35 ~]# kubectl version 
    Client Version: version.Info{Major:"1", Minor:"11+", GitVersion:"v1.11.0-168+f47446a730ca03", GitCommit:"f47446a730ca037473fb3bf0c5abeea648c1ac12", GitTreeState:"clean", BuildDate:"2018-08-25T21:05:52Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}
    Server Version: version.Info{Major:"1", Minor:"11+", GitVersion:"v1.11.0-168+f47446a730ca03", GitCommit:"f47446a730ca037473fb3bf0c5abeea648c1ac12", GitTreeState:"clean", BuildDate:"2018-08-25T21:05:52Z", GoVersion:"go1.10.3", Compiler:"gc", Platform:"linux/amd64"}

准备ConfigMap

token gitlab  
从gitlab服务中获取

![to][]

[root@master-47-35 gitlab]# cat configmap.yaml 
    apiVersion: v1
    kind: ConfigMap
    metadata:
      name: gitlab-runner
      namespace: gitlab
    data:
      config.toml: |
        concurrent = 4
    
        [[runners]]
          name = "Kubernetes Runner"
          url = "http://10.39.47.63/"
          token = "d4027a7f23390e8e2519d93564c0a7"
          executor = "kubernetes"
          [runners.kubernetes]
            namespace = "gitlab"
            image = "busybox"

deployment

[root@master-47-35 gitlab]# cat deployment.yaml 
    apiVersion: extensions/v1beta1
    kind: Deployment
    metadata:
      name: gitlab-runner
      namespace: gitlab
    spec:
      replicas: 1
      selector:
        matchLabels:
          name: gitlab-runner
      template:
        metadata:
          labels:
            name: gitlab-runner
        spec:
          containers:
          - args:
            - run
            image: harbor.enncloud.cn/paas/gitlab-runner:latest
            imagePullPolicy: IfNotPresent
            name: gitlab-runner
            volumeMounts:
            - mountPath: /etc/gitlab-runner
              name: config
            - mountPath: /etc/kubernetes/ssl/
              name: cacerts
              readOnly: true
            - mountPath: /var/run/docker.sock
              name: docker-sock
              readOnly: true
          restartPolicy: Always
          hostNetwork: true
          volumes:
          - configMap:
              name: gitlab-runner
            name: config
          - hostPath:
              path: /etc/kubernetes/ssl/
            name: cacerts
          - hostPath:
              path: /var/run/docker.sock
            name: docker-sock

创建名为gitlab的namespace,

kubectl create ns gitlab

部署

[root@master-47-35 gitlab]# kubectl create -f configmap.yaml 
    configmap/gitlab-runner created
    [root@master-47-35 gitlab]# kubectl create -f deployment.yaml 
    deployment.extensions/gitlab-runner created

进入到容器注册gitlab-runner

[root@master-47-35 gitlab]# kubectl exec -it gitlab-runner-7dcfcb8d44-d4vdf sh -n gitlab

![k8s][]

查看部署结果

[root@master-47-35 gitlab]# kubectl get pods -n gitlab -owide
    NAME                             READY     STATUS    RESTARTS   AGE       IP              NODE          NOMINATED NODE
    gitlab-runner-7dcfcb8d44-d4vdf   1/1       Running   0          43s       10.253.109.42   slave-47-33   <none>

![k8s][k8s 1]

注意文件`config.toml`这个里面的token要跟页面的一样  
![token][]

root@slave-47-33:/# cat /etc/gitlab-runner/config.toml 
    concurrent = 4
    
    [[runners]]
      name = "Kubernetes Runner"
      url = "http://10.39.47.63/"
      token = "75a8c62d5b0652dff24c57c341fc60"
      executor = "kubernetes"
      [runners.kubernetes]
         namespace = "gitlab"
         namespace_overwrite_allowed = "ci-.*"
         bearer_token_overwrite_allowed = true
         privileged = true
