K8S容器环境下GitLab-CI和GItLab Runner 部署记录

 
一、简单介绍
 
GitLab-CI
  • GitLab CI/CD是GitLab的一部分,支持从计划到部署具有出色的用户体验。CI/CD是开源GitLab社区版和专有GitLab企业版的一部分。可以根据需要添加任意数量的计算节点,每个构建可以拆分为多个作业,这些作业可以在多台计算机上并行运行。
  • GitLab-CI轻量级,不需要复杂的安装手段。配置简单,与gitlab可直接适配。实时构建日志十分清晰,UI交互体验很好。使用 YAML 进行配置,任何人都可以很方便的使用。GitLabCI 有助于DevOps人员,例如敏捷开发中,开发与运维是同一个人,最便捷的开发方式。
  • 在大多数情况,构建项目都会占用大量的系统资源,如果让gitlab本身来运行构建任务的话,显然Gitlab的性能会大幅度下降。GitLab-CI最大的作用就是管理各个项目的构建状态。因此,运行构建任务这种浪费资源的事情交给一个独立的Gitlab Runner来做就会好很多,更重要的是Gitlab Runner 可以安装到不同的机器上,甚至是我们本机,这样完全就不会影响Gitlab本身了。
  • 从GitLab8.0开始,GitLab-CI就已经集成在GitLab中,我们只需要在项目中添加一个.gitlab-ci.yaml文件,然后运行一个Runner,即可进行持续集成。
 
GitLab-CI:集成、开源、无缝、可扩展、更快的结果、针对交付进行了优化:
 
GItLab Runner
  • Gitlab Runner是一个开源项目,用于运行您的作业并将结果发送给gitlab。它与Gitlab CI结合使用,gitlab ci是Gitlab随附的用于协调作用的开源持续集成服务。
  • Gitlab Runner是用Go编写的,可以作为一个二进制文件运行,不需要特定于语言的要求
  • 它皆在GNU/Linux,MacOS和Windows操作系统上运行。另外注意:如果要使用Docker,Gitlab Runner要求Docker 至少是v1.13.0版本才可以。

二、基于Kubernetes Gitlab CICD 容器化部署记录
  • Gitlab官方提供了Helm的方式在Kubernetes集群中来快速安装,但是在使用的过程中发现Helm提供的Chart包中有很多其他额外的配置。所以这里我采用K8S自定义的方式来安装。
  • Gitlab主要涉及3个应用:Redis、Postgresql、Gitlab核心程序。
  • 本案例中使用的Gitlab-ce镜像部署,镜像中的Gitlab版本是13.7.4。
  • 本案例中使用NFS作为持久化存储方式。除此之外,还可以选择HostPath本地持久化存储、NAS云端持久化存储、Ceph分布式持久化存储等。
注意:本示例部署所涉及到的image镜像均导入到Harbor私有私仓(172.16.60.230) 。
 
1)使用NFS作为持久化存储
在NFS服务器端(172.16.60.238)创建Redis、Postgresql、Gitlab核心程序容器的持久化挂载目录
 
[root@k8s-harbor01 ~]# mkdir -p /data/storage/k8s/gitlab/{postgresql,redis,gitlab}
[root@k8s-harbor01 ~]# ll /data/storage/k8s/gitlab/
total 0
drwxr-xr-x 2 root root 6 Mar 25 14:03 gitlab
drwxr-xr-x 2 root root 6 Mar 25 14:03 postgresql
drwxr-xr-x 2 root root 6 Mar 25 14:03 redis

  

2)部署Gitlab
可以先创建一个命名空间
 
[root@k8s-master01 gitlab]# kubectl create ns kube-ops

[root@k8s-master01 gitlab]# kubectl get ns|grep kube-ops
kube-ops              Active   7d18h

配置三个核心程序的容器化部署的yaml文件

[root@k8s-master01 gitlab]# pwd
/opt/k8s/k8s_project/gitlab
[root@k8s-master01 gitlab]# ll
total 12
-rw-r--r-- 1 root root 1629 Mar 25 14:05 gitlab-postgresql.yaml
-rw-r--r-- 1 root root 1207 Mar 25 14:05 gitlab-redis.yaml

创建并启动gitlab相关容器进程:
[root@k8s-master01 gitlab]# ll
total 12
-rw-r--r-- 1 root root 1629 Mar 25 14:05 gitlab-postgresql.yaml
-rw-r--r-- 1 root root 1207 Mar 25 14:05 gitlab-redis.yaml
-rw-r--r-- 1 root root 2691 Mar 25 14:05 gitlab.yaml

[root@k8s-master01 gitlab]# kubectl apply -f .
deployment.apps/postgresql created
service/postgresql created
deployment.apps/redis created
service/redis created
deployment.apps/gitlab created
service/gitlab created

  

稍微等一会儿(由于程序启动顺序原因,pod可能会出现重启次数,不过最终都会启动成功),
查看pod状态:
[root@k8s-master01 gitlab]# kubectl get pods -n kube-ops
NAME                          READY   STATUS    RESTARTS   AGE
gitlab-5b887894d5-ntxzj       1/1     Running   1          38m
postgresql-57bf98cdf8-7mdh9   1/1     Running   1          38m
redis-56769dc6b6-c4rnq        1/1     Running   0          38m

  

查看svc:
[root@k8s-master01 gitlab]# kubectl get svc -n kube-ops
NAME         TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)                     AGE

redis        ClusterIP   10.254.198.0   <none>        6379/TCP     

  

3)访问 Gitlab
  • 这里采用NodePort的方式,通过 http://任意node节点ip:30004 地址访问Gitlab
  • Gitlab登录用户名:root,密码:admin321
  • Gitlab登录密码可以在yaml文件里修改

这里容器化部署后的Gitlab版本是13.7.4

 4)创建演示项目

接下来顺便创建一个项目,用于演示:

 

 
 
 
接下来在服务器上git clone,进行代码提交演示:
地址中的gitlab-5b887894d5-ntxzj是pod名称,在容器外部访问不了,需要修改为对应的nodeport地址,故git clone地址可以是:http://172.16.60.234:30004/root/kevin-test.git
 
在其中一个node节点上进行代码提交演示:
[root@k8s-node02 mnt]# mkdir /mnt/haha
[root@k8s-node02 mnt]# cd /mnt/haha
[root@k8s-node02 haha]# git config --global user.email "1025337607@qq.com"
[root@k8s-node02 haha]# git config --global user.name "Administrator"
[root@k8s-node02 haha]#

如何解决 "每次输入用户名和密码" 的问题?
在代码目录.git/config文件内[remote "origin"]的url的gitlab域名前添加gitlab注册时的"用户名:密码@"
[root@k8s-node02 kevin-test]# cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = http://root:admin321@172.16.60.234:30004/root/kevin-test.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master

  

接着再次尝试提交内容,就不需要手动输入用户名和密码了:
[root@k8s-node02 kevin-test]# git pull
Already up-to-date.

[root@k8s-node02 kevin-test]# echo "this is gitlab test" > test.md

代码上传后,gitlab上展示效果如下:

 
 
 
进入该项目下,左侧栏CICD里有三种方式:Pipelines、Jobs、Schedules
 
5)Gitlab Runner 安装和注册
gitlab runner支持多种方式安装,我这里就采取在k8s中安装。
 
打开gitlab,如下图所示,左边代表runner状态,右边是配置runner信息。
注意右边栏的token信息,后面注册runner的时候会用到:
 
 
接下来进行配置gitlab runner资源清单 (runner-configmap.yaml)
[root@k8s-master01 gitlab]# cat runner-configmap.yaml
apiVersion: v1
data:
  REGISTER_NON_INTERACTIVE: "true"
  REGISTER_LOCKED: "false"
  METRICS_SERVER: "0.0.0.0:9100"
  CI_SERVER_URL: "http://gitlab.kube-ops.svc.cluster.local/ci"
  RUNNER_REQUEST_CONCURRENCY: "4"
  RUNNER_EXECUTOR: "kubernetes"
  KUBERNETES_NAMESPACE: "kube-ops"
  KUBERNETES_PRIVILEGED: "true"
  KUBERNETES_CPU_LIMIT: "1"
  KUBERNETES_CPU_REQUEST: "500m"
  KUBERNETES_MEMORY_LIMIT: "1Gi"
  KUBERNETES_SERVICE_CPU_LIMIT: "1"
  KUBERNETES_SERVICE_MEMORY_LIMIT: "1Gi"
  KUBERNETES_HELPER_CPU_LIMIT: "500m"
  KUBERNETES_HELPER_MEMORY_LIMIT: "100Mi"
  KUBERNETES_PULL_POLICY: "if-not-present"
  KUBERNETES_TERMINATIONGRACEPERIODSECONDS: "10"
  KUBERNETES_POLL_INTERVAL: "5"
  KUBERNETES_POLL_TIMEOUT: "360"
kind: ConfigMap
metadata:
  labels:
    app: gitlab-ci-runner
  name: gitlab-ci-runner-cm
  namespace: kube-ops

  

需要注意:
  • CI_SERVER_URL 这个地址是gitlab的地址,如果gitlab在宿主机直接写宿主机的ip即可,容器是格式为:svc名称.命名空间.svc.cluster.local (如果都按照我的文档来进行安装不需要修改别的配置了)。
  • 如果定义的gitlab域名并不是通过外网DNS解析,而是通过/etc/hosts进行映射,那么我们需要在Runner的Pod中去添加对应的hosts,需要通过--pre-clone-script参数来指定一段脚本来添加hosts信息,也就是在ConfigMap中添加环境变量RUNNER_PRE_CLONE_SCRIPT的值:
本案例,这里gitlab地址我是使用node节点的ip+port方式。 如果使用gitlab域名方式,且不是外网DNS解析,比如域名地址是http://gitlab.kevin.com 则需要在上面的ConfigMap中添加环境变量RUNNER_PRE_CLONE_SCRIPT的值: RUNNER_PRE_CLONE_SCRIPT = "echo 'xx.xx.xxx.xx git.i4t.com' >> /etc/hosts" 其中xx.xx.xxx.xx 为node节点ip地址
 
另外记住:在ConfigMap添加新选项后,需要删除Gitlab ci Runner Pod
因为这里我是使用envFrom来注入上面的这些环境变量而不是直接使用env(envfrom 通过将环境变量放置到ConfigMaps或Secrets来帮助减小清单文件)
如果我们想添加其他选项,那么可以在等到后面的gitlab-ci-runner的Pod容器启动成功后,登录gitlab-ci-runner的pod容器内部运行gitlab-ci-multi-runner register --help 命令来查看所有可使用的选项,只需要为配置的标志添加env变量即可:
 
gitlab-runner@gitlab-ci-runner-0:/$ gitlab-ci-multi-runner register --help
[...]
--kubernetes-cpu-limit value                          The CPU allocation given to build containers (default: "1") [$KUBERNETES_CPU_LIMIT]

[root@k8s-master01 gitlab]# kubectl apply -f runner-configmap.yaml
configmap/gitlab-ci-runner-cm created
[root@k8s-master01 gitlab]# kubectl get configmaps  -n kube-ops
NAME                  DATA   AGE
gitlab-ci-runner-cm   19     4s

可通过下面命令来查看此configmap内容:
[root@k8s-master01 gitlab]# kubectl describe cm gitlab-ci-runner-cm -n kube-ops

  

此时,还需要配置一个用于注册、运行和取消gitlab ci runner的小脚本。只有当Pod正常通过K8S (TERM信号)的终止流程时,才会触发注销注册。如果强行终止Pod(SIGKILL信号),Runner将不会自己注销自身。必须手动完成对这种Runner的清理 (注意:只有如这里在k8s集群里安装GitLan Runner才这样操作,二进制安装非K8s上安装则不受这个影响)
[root@k8s-master01 gitlab]# cat runner-scripts-cm.yaml
apiVersion: v1
data:
  run.sh: |
    #!/bin/bash
    unregister() {
        kill %1
        echo "Unregistering runner ${RUNNER_NAME} ..."
        /usr/bin/gitlab-ci-multi-runner unregister -t "$(/usr/bin/gitlab-ci-multi-runner list 2>&1 | tail -n1 | awk '{print $4}' | cut -d'=' -f2)" -n ${RUNNER_NAME}
        exit $?
    }
    trap 'unregister' EXIT HUP INT QUIT PIPE TERM
    echo "Registering runner ${RUNNER_NAME} ..."
    /usr/bin/gitlab-ci-multi-runner register -r ${GITLAB_CI_TOKEN}
    sed -i 's/^concurrent.*/concurrent = '"${RUNNER_REQUEST_CONCURRENCY}"'/' /home/gitlab-runner/.gitlab-runner/config.toml
    echo "Starting runner ${RUNNER_NAME} ..."
    /usr/bin/gitlab-ci-multi-runner run -n ${RUNNER_NAME} &
    wait
kind: ConfigMap
metadata:
  labels:
    app: gitlab-ci-runner
  name: gitlab-ci-runner-scripts
  namespace: kube-ops

  

创建此脚本的configmap
[root@k8s-master01 gitlab]# kubectl apply -f runner-scripts-cm.yaml
configmap/gitlab-ci-runner-scripts created

[root@k8s-master01 gitlab]# kubectl get configmaps  -n kube-ops
NAME                       DATA   AGE
gitlab-ci-runner-cm        19     4m12s
gitlab-ci-runner-scripts   1      11s

  

接着需要创建一个GITLAB_CI_TOKEN,然后使用gitlab ci runner token来创建一个Kubernetes secret对象。需要提前对token进行base64转码:
[root@k8s-master01 gitlab]# echo xWgpgrP3rSXnxvZL9oRf|base64 -w0
eFdncGdyUDNyU1hueHZaTDlvUmYK

  

特意注意:这里的token就是我们gitlab runner上截图的地方,base64只有在k8s环境上需要!
登录Gitlab,Runner右边栏token信息 如下图:
使用上面的token创建一个Sercret对象 (gitlab-ci-token-secret.yaml)
[root@k8s-master01 gitlab]# cat gitlab-ci-token-secret.yaml
apiVersion: v1
kind: Secret
metadata:
  name: gitlab-ci-token
  namespace: kube-ops
  labels:
    app: gitlab-ci-runner
data:
  GITLAB_CI_TOKEN: eFdncGdyUDNyU1hueHZaTDlvUmYK

  

创建这个Secret
[root@k8s-master01 gitlab]# kubectl apply -f gitlab-ci-token-secret.yaml
secret/gitlab-ci-token created

[root@k8s-master01 gitlab]# kubectl get secret -n kube-ops|grep gitlab
gitlab-ci-token       Opaque                                1      19s

  

接下来创建真正运行Runner的控制器镜像,这里使用Statefulset,在开始运行的时候,尝试取消注册所有的同名Runner,当节点丢失时(即NodeLost事件),这尤其有用,然后再尝试注册自己并开始运行。在正常停止Pod的时候,Runner将会运行unregister命令来尝试取消自己,所以gitlab就不能再使用这个Runner,这个则是通过kubernetes Pod生命周期中的hooks来完成的:
 
编译gitlab runner的pod部署的yaml文件内容:
[root@k8s-master01 gitlab]# cat runner-statefulset.yaml
apiVersion: v1
kind: Service
metadata:
  name: gitlab-ci-runner
  namespace: kube-ops
  labels:

    metadata:
      labels:

    spec:
      volumes:
      - name: gitlab-ci-runner-scripts
        projected:
          sources:
          - configMap:
              name: gitlab-ci-runner-scripts
              items:
              - key: run.sh
                path: run.sh
                mode: 0755
      serviceAccountName: gitlab-ci
      securityContext:
        runAsNonRoot: true
        runAsUser: 999
        supplementalGroups: [999]
      containers:
      - image: 172.16.60.230/gitlab/gitlab-runner:latest
        name: gitlab-ci-runner
        command:
        - /scripts/run.sh
        envFrom:
        - configMapRef:
            name: gitlab-ci-runner-cm
        - secretRef:
            name: gitlab-ci-token
        env:
        - name: RUNNER_NAME
          valueFrom:
            fieldRef:
              fieldPath: metadata.name
        ports:
        - containerPort: 9100
          name: http-metrics
          protocol: TCP
        volumeMounts:
        - name: gitlab-ci-runner-scripts
          mountPath: "/scripts"
          readOnly: true
      restartPolicy: Always

  

上面我们命名了一个gitlab-ci的serviceAccount,这里要新建一个rbac文件 (runner-rbac.yaml)
[root@k8s-master01 gitlab]# cat runner-rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: gitlab-ci
  namespace: kube-ops
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: gitlab-ci
  namespace: kube-ops
rules:
  - apiGroups: [""]
    resources: ["*"]
    verbs: ["*"]
---
kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: gitlab-ci
  namespace: kube-ops
subjects:
  - kind: ServiceAccount
    name: gitlab-ci
    namespace: kube-ops
roleRef:
  kind: Role
  name: gitlab-ci
  apiGroup: rbac.authorization.k8s.io

  

创建gitlab runner
[root@k8s-master01 gitlab]# kubectl apply -f runner-rbac.yaml
serviceaccount/gitlab-ci created
role.rbac.authorization.k8s.io/gitlab-ci created
rolebinding.rbac.authorization.k8s.io/gitlab-ci created

[root@k8s-master01 gitlab]# kubectl apply -f runner-statefulset.yaml
service/gitlab-ci-runner unchanged
statefulset.apps/gitlab-ci-runner created

  

接下来我们检查我们创建的资源信息:
[root@k8s-master01 gitlab]# kubectl get pod,svc,cm -n kube-ops
NAME                              READY   STATUS    RESTARTS   AGE
pod/gitlab-5b887894d5-ntxzj       1/1     Running   1          150m

service/gitlab             NodePort    10.254.252.242   <none>        80:30004/TCP,22:31455/TCP   150m
service/gitlab-ci-runner   ClusterIP   None             <none>        9100/TCP                    13m

configmap/gitlab-ci-runner-cm        19     36m
configmap/gitlab-ci-runner-scripts   1      32m

  

此时,在登录Gitlab,查看Runner信息,发现就已经将这2个pod节点添加进来了:
 
 
这里我们也可以更改Runner的一些配置,比如添加tag标签等:
 
 
6)Gitlab Runner 配置使用
这里上传了一个测试项目gitlab-ci-k8s-demo-master,下面介绍:在gitlab项目里添加k8s集群(只要一个项目添加成功后,其他项目也都添加了)

另外注意:CI/CD的Auto DevOps里的"Default to Auto DevOps pipeline“ 如果有勾选,则需要去掉这个勾选,否则会对集成k8s产生影响。

接下来要配置一下kubectl,默认情况下kubectl需要使用证书才可以连接到k8s集群。在服务器上默认使用的是/root/.kube/config,gitlab 也有添加证书的位置,下面进行添加配置。

  

 

这里简单说明下:
  • Kubernetes cluster name 集群名称,这个可以随便写
  • API URL 这里实际上就是apiserver地址,通过kubectl cluster-info查看到
  • CA Certificate、Service Token 可以通过/root/.kube/config 或下面方式得到
 
Kubernetes cluster 名称
这里顺便填写一个,比如:kevin-k8s-cluster
 
API URL地址
可以通过"kubectl cluster-info"命令获取
[root@k8s-master01 gitlab]# kubectl cluster-info
Kubernetes master is running at https://127.0.0.1:8443
CoreDNS is running at https://127.0.0.1:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Metrics-server is running at https://127.0.0.1:8443/api/v1/namespaces/kube-system/services/https:metrics-server:/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
 
由于这里的k8s集群中的kube-apiserver高可用通过local nginx+haproxy实现的,所以需要将https://127.0.0.1:8443 改为其中的一个master地址,这里填写:https://172.16.60.231:8443
 
CA Certificate、Service Token 值
这里没有使用/root/.kube/config获取Service Token,而是采用下面的方式获取:
这里提醒一下:cluster-admin是内置的一个角色,拥有集群所有权限的一个角色
这里先创建一个命名空间
[root@k8s-master01 gitlab]# kubectl create ns gitlab
namespace/gitlab created

因为在操作的时候会涉及rbac权限的问题,这里要创建一个rbac的文件。我们将集群的cluster的权限绑定到ServerAccount
[root@k8s-master01 gitlab]# pwd
/opt/k8s/k8s_project/gitlab

[root@k8s-master01 gitlab]# cat gitlabdemo-sa.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: gitlab
  namespace: gitlab

---
apiVersion: rbac.authorization.k8s.io/v1beta1
kind: ClusterRoleBinding
metadata:
  name: gitlab
subjects:
  - kind: ServiceAccount
    name: gitlab
    namespace: gitlab
roleRef:
    apiGroup: rbac.authorization.k8s.io
    kind: ClusterRole
    name: cluster-admin

进行创建
[root@k8s-master01 gitlab]# kubectl apply -f gitlabdemo-sa.yaml
serviceaccount/gitlab created
clusterrolebinding.rbac.authorization.k8s.io/gitlab created

查看
[root@k8s-master01 gitlab]# kubectl get sa -n gitlab
NAME      SECRETS   AGE
default   1         2m55s
gitlab    1         17s

  

上面创建的serviceaccount实际上就是一个secret,接下来我们进行获取Service Token和CA Certificate
[root@k8s-master01 gitlab]# kubectl get secret -n gitlab
NAME                  TYPE                                  DATA   AGE

gitlab-token-ddhs6    kubernetes.io/service-account-token   3      95s

[root@k8s-master01 gitlab]# kubectl get secrets gitlab-token-ddhs6 -n gitlab -o yaml

上面结果中的ca.crt内容进行base64转码才能得到CA Certificate
需要通过命令"echo "xxxx"|base64 -d"使用base64进行转码
"xxxx"是ca.crt的内容
