一.环境准备

1.导入镜像

[root@worker233 ~]# wget http://192.168.21.253/Resources/Kubernetes/Project/DevOps/images/yinzhengjie-gitlab-ce-v17.5.2.tar.gz
[root@worker233 ~]# docker load -i yinzhengjie-gitlab-ce-v17.5.2.tar.gz 
[root@worker233 ~]# docker tag gitlab/gitlab-ce:17.5.2-ce.0  harbor250.yinzhengjie.com/yinzhengjie-devops/gitlab-ce:17.5.2-ce.0
[root@worker233 ~]# docker push harbor250.yinzhengjie.com/yinzhengjie-devops/gitlab-ce:17.5.2-ce.0

2.创建nfs共享目录

[root@master231 ~]# mkdir -pv /yinzhengjie/data/nfs-server/case-demo/gitlab/{data,logs,conf}
mkdir: created directory '/yinzhengjie/data/nfs-server/case-demo/gitlab'
mkdir: created directory '/yinzhengjie/data/nfs-server/case-demo/gitlab/data'
mkdir: created directory '/yinzhengjie/data/nfs-server/case-demo/gitlab/logs'
mkdir: created directory '/yinzhengjie/data/nfs-server/case-demo/gitlab/conf'
[root@master231 ~]# 

二.K8S部署GitLab

1.编写资源清单

[root@master231 02-jenkins]# cat 01-deploy-svc-gitlab.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: deploy-gitlab
spec:
  replicas: 1
  selector:
    matchLabels:
      apps: gitlab
  template:
    metadata:
      labels:
        apps: gitlab
    spec:
      volumes:

   - name: data
     nfs:
       server: 10.0.0.231
       path: /yinzhengjie/data/nfs-server/case-demo/gitlab/data
        - name: conf
          nfs:
            server: 10.0.0.231
            path: /yinzhengjie/data/nfs-server/case-demo/gitlab/conf
             - name: logs
               nfs:
                 server: 10.0.0.231
                 path: /yinzhengjie/data/nfs-server/case-demo/gitlab/logs
                     containers:
                  - name: c1
                    image: harbor250.yinzhengjie.com/yinzhengjie-devops/gitlab-ce:17.5.2-ce.0
                    ports:
     - containerPort: 22
       name: ssh
     - containerPort: 80
       name: http
     - containerPort: 443
       name: https
       volumeMounts:
     - name: logs
       mountPath: /var/log/gitlab
     - name: data
       mountPath: /var/opt/gitlab
     - name: conf
       mountPath: /etc/gitlab

---

apiVersion: v1
kind: Service
metadata:
  name: svc-gitlab
spec:
  type: LoadBalancer
  selector:
    apps: gitlab
  ports:

  - protocol: TCP
    port: 80
    name: http
  - protocol: TCP
    port: 443
    name: https
  - protocol: TCP
    port: 22
    name: sshd
[root@master231 02-jenkins]# 
[root@master231 02-jenkins]# 

2.创建资源

[root@master231 02-jenkins]# kubectl apply -f  01-deploy-svc-gitlab.yaml 
deployment.apps/deploy-gitlab created
service/svc-gitlab created
[root@master231 02-jenkins]# 
[root@master231 02-jenkins]# kubectl get svc svc-gitlab 
NAME         TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                                   AGE
svc-gitlab   LoadBalancer   10.200.237.106   10.0.0.153    80:41391/TCP,443:15760/TCP,22:39022/TCP   9m12s
[root@master231 02-jenkins]# 
[root@master231 02-jenkins]# kubectl get pods -o wide  # GitLab是否能够正常访问，需要等待7-8m左右就可以正常访问。性能如果好一点，3-5m就可以正常访问了。
NAME                            READY   STATUS    RESTARTS   AGE     IP            NODE        NOMINATED NODE   READINESS GATES
deploy-gitlab-c84979449-f5rn9   1/1     Running   0          9m16s   10.100.2.53   worker233   <none>           <none>
[root@master231 02-jenkins]# 
[root@master231 02-jenkins]# 

3.查看gitlab的初始密码

[root@master231 02-jenkins]# kubectl logs  deploy-gitlab-c84979449-f5rn9 | grep /etc/gitlab/initial_root_password
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.
[root@master231 02-jenkins]# 
[root@master231 02-jenkins]# kubectl exec deploy-gitlab-c84979449-f5rn9  -- cat /etc/gitlab/initial_root_password

# 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_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).

#          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/reset_user_password.html#reset-your-root-password.

Password: a9/WZNn+4VHTjFa3pd6h2niEodrEYQUcepGNjWc7AEc=

# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.

[root@master231 02-jenkins]#

4.访问测试

http://10.0.0.153/

​

用上一步的密码进行登录，用户名为: root 

5.修改密码

如上图所示，按照步骤依次执行即可修改密码，注意密码长度不得少于8位哟~
