K8S部署gitlab deployment：基于nfs进行数据持久化

## 准备工作 ##

### 1.1 创建nfs共享目录 ###

在nfs服务器创建共享目录，部署的gitlib使用共享目录来进行持久化，这样不管在哪个节点运行gitlib都没有关系。

# mkdir -p /home/k8s-nfs/gitlab/config
    
    # mkdir -p /home/k8s-nfs/gitlab/logs
    
    # mkdir -p /home/k8s-nfs/gitlab/data

### 1.2 添加到共享 ###

vim /etc/exports
    /home/k8s-nfs/gitlab/config 192.168.17.0/8(rw,no_root_squash)
    /home/k8s-nfs/gitlab/logs 192.168.17.0/8(rw,no_root_squash)
    /home/k8s-nfs/gitlab/data 192.168.17.0/8(rw,no_root_squash)

### 1.3 执行更新 ###

# service nfs restart
    
    或者
    
    # exportfs -r

## 部署gitlib ##

### 2.1 准备部署文件（gitlib-deploy.yaml） ###

apiVersion: v1
    kind: Service
    metadata:
      name: gitlab
    spec:
      type: NodePort
      ports:
      # Port上的映射端口
      - port: 443
        targetPort: 443
        name: gitlab443
      - port: 80
        targetPort: 80
        name: gitlab80
      - port: 22
        targetPort: 22
        name: gitlab22
      selector:
        app: gitlab
     
    ---
     
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: gitlab
    spec:
      selector:
        matchLabels:
          app: gitlab
      revisionHistoryLimit: 2
      template:
        metadata:
          labels:
            app: gitlab
        spec:
          containers:
          # 应用的镜像
          - image: gitlab/gitlab-ce 
            name: gitlab
            imagePullPolicy: IfNotPresent
            # 应用的内部端口
            ports:
            - containerPort: 443
              name: gitlab443
            - containerPort: 80
              name: gitlab80
            - containerPort: 22
              name: gitlab22
            volumeMounts:
            # gitlab持久化
            - name: gitlab-persistent-config
              mountPath: /etc/gitlab
            - name: gitlab-persistent-logs
              mountPath: /var/log/gitlab
            - name: gitlab-persistent-data
              mountPath: /var/opt/gitlab
          imagePullSecrets:
          - name: devops-repo
          volumes:
          # 使用nfs互联网存储
          - name: gitlab-persistent-config
            nfs:
              server: 192.168.17.81
              path: /home/k8s-nfs/gitlab/config
          - name: gitlab-persistent-logs
            nfs:
              server: 192.168.17.81
              path: /home/k8s-nfs/gitlab/logs
          - name: gitlab-persistent-data
            nfs:
              server: 192.168.17.81
              path: /home/k8s-nfs/gitlab/data

### 2.2 执行部署 ###

# kubectl apply -f gitlib-deploy.yaml

### 2.3 查看部署结果 ###

# kubectl get deploy 
    
    NAME     READY   UP-TO-DATE   AVAILABLE   AGE
    gitlab   1/1     1            1           134m

以上说明部署完成。

## gitlib初始化 ##

### 3.1 访问登录页面 ###

通过查看service映射的端口：

# kubectl get svc -o wide
    
    NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                                   AGE    SELECTOR
    gitlab       NodePort    10.10.129.28    <none>        443:31326/TCP,80:31320/TCP,22:31515/TCP   137m   app=gitlab

可以看到映射80端口的节点端口为：31320

通过指定端口访问登录页：

### 3.2 初始用户名和密码 ###

初始用户名为root，初始密码gitlib自动创建，在如下文件中：

cat /etc/gitlab/initial_root_password

由于是容器部署，所以，需要进入到容器中，找到对应文件，拷贝密码进行登录。文件内容类似：

# WARNING: This value is valid only in the following conditions
    
    # 1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_passwo
    
    # 2. Password hasn't been changed manually, either via UI or via command line.
    
    #
    
    # If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/
    
    Password: HCsr5VFAp28N*****************=
    
    # NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
