gitlab cicd (四)系列之安装git-runner kubernetes安装方式
本编博客是继gitlab cicd (三)系列之安装git-runner docker安装方式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
[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
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
注意文件config.toml这个里面的token要跟页面的一样
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
[root@master-47-35 gitlab]# kubectl get pods -n gitlab
