Helm部署Gitlab

搭建nfs服务器https://mp.weixin.qq.com/s?__biz=MzU0NjEwMTg4Mg==&mid=2247485185&idx=1&sn=2b5646119a008d69948c5a84d3724c95&scene=58&subscene=0
1.为什么搭建nfs服务器？**

因为我们要使用nfs作为持久化存储，创建的pv后端存储时需要nfs，所以需要搭建nfs服务。
**2.安装nfs服务

**
选择自己的任意一台机器，我选择k8s的master1节点，对应的机器ip是192.168.0.6，在192.168.0.6上执行如下步骤，大家在自己环境找一台k8s节点的机器安装就可以了~

（1）yum安装nfs
yum install nfs-utils -y
systemctl start nfs
chkconfig nfs on
（2）在master1上创建一个nfs共享目录
mkdir /data/v3 -p
mkdir /data/v4
mkdir /data/v5
cat /etc/exports
/data/v3 192.168.0.0/24(rw,no_root_squash)
/data/v4 192.168.0.0/24(rw,no_root_squash)
/data/v5 192.168.0.0/24(rw,no_root_squash)
exportfs -arv 使配置文件生效
systemctl restart nfs
（3）k8s的各个node节点也需要安装nfs
yum install nfs-utils -y
systemctl start nfs
chkconfig nfs on

**创建安装gitlab需要的pv和pvc

**1.创建一个名称空间

kubectl create ns kube-ops
2.创建gitlab需要的pv和pvc
cat pv_pvc_gitlab.yaml
apiVersion: v1kind: PersistentVolumemetadata: name: gitlabtspec: capacity: storage: 10Gi accessModes: - ReadWriteMany persistentVolumeReclaimPolicy: Delete nfs: server: 192.168.0.6 #这个就是nfs服务端的机器ip，也就是k8s的master1节点ip path: /data/v5—-kind: PersistentVolumeClaimapiVersion: v1metadata: name: gitlabt namespace: kube-opsspec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi
注意：
nfs: server: 192.168.0.6 #这个就是nfs服务端的机器ip，也就是k8s的master1节点ip
通过kubectl apply更新yaml文件
kubectl apply -f pv_pvc_gitlab.yaml
查看pv和pvc是否绑定
kubectl get pvc -n kube-ops
显示如下，说明绑定成功了
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGEgitlabt Bound gitlabt 10Gi RWX 2m
3.创建postsql的pv和pvc

cat pv_pvc_postsql.yaml
apiVersion: v1kind: PersistentVolumemetadata: name: postsqlspec: capacity: storage: 10Gi accessModes: - ReadWriteMany persistentVolumeReclaimPolicy: Delete nfs: server: 192.168.0.6 path: /data/v4—-kind: PersistentVolumeClaimapiVersion: v1metadata: name: postsql namespace: kube-opsspec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi
通过kubectl apply更新yaml文件
kubectl apply -f pv_pvc_postsql.yaml
查看pv和pvc是否绑定
kubectl get pvc -n kube-ops
显示如下，说明postsql的pvc和pv绑定成功了
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGEgitlabt Bound gitlabt 10Gi RWX 5m6spostsql Bound postsql 10Gi RWX 2s
4.创建redis的pv和pvc
cat pv_pvc_redis.yaml
apiVersion: v1kind: PersistentVolumemetadata: name: dataspec: capacity: storage: 20Gi accessModes: - ReadWriteMany persistentVolumeReclaimPolicy: Delete nfs: server: 192.168.0.6 path: /data/v3—-kind: PersistentVolumeClaimapiVersion: v1metadata: name: data namespace: kube-opsspec: accessModes: - ReadWriteMany resources: requests: storage: 20Gi
通过kubectl apply更新yaml文件
kubectl apply -f pv_pvc_redis.yaml
查看pv和pvc是否绑定
kubectl get pvc -n kube-ops
显示如下，说明gitlab的pvc和pv绑定成功了
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGEdata Bound data 20Gi RWX 5sgitlabt Bound gitlabt 10Gi RWX 7m7spostsql Bound postsql 10Gi RWX 2m3s
安装postgresql服务

通过kubectl apply更新yaml文件
kubectl apply -f gitlab-postgresql.yaml
查看postgresql是否部署成功
kubectl get pods -n kube-ops
显示如下，说明postgresql部署成功
NAME READY STATUS RESTARTS AGEpostgresql-79f85cdfb4-r64q5 1/1 Running 0 68s
**安装gitlab需要的redis服务

cat gitlab-redis.yaml
apiVersion: apps/v1kind: Deploymentmetadata: name: redis namespace: kube-ops labels: name: redisspec: selector: matchLabels: name: redis template: metadata: name: redis labels: name: redis spec: containers: - name: redis image: sameersbn/redis imagePullPolicy: IfNotPresent ports: - name: redis containerPort: 6379 volumeMounts: - mountPath: /var/lib/redis name: data livenessProbe: exec: command: - redis-cli - ping initialDelaySeconds: 30 timeoutSeconds: 5 readinessProbe: exec: command: - redis-cli - ping initialDelaySeconds: 5 timeoutSeconds: 1 volumes: - name: data persistentVolumeClaim: claimName: data—-apiVersion: v1kind: Servicemetadata: name: redis namespace: kube-ops labels: name: redisspec: ports: - name: redis port: 6379 targetPort: redis selector: name: redis

**安装gitlab服务

cat gitlab.yaml
apiVersion: apps/v1kind: Deploymentmetadata: name: gitlab namespace: kube-ops labels: name: gitlabspec: selector: matchLabels: name: gitlab template: metadata: name: gitlab labels: name: gitlab spec: containers: - name: gitlab image: sameersbn/gitlab:11.8.1 imagePullPolicy: IfNotPresent env: - name: TZ value: Asia/Shanghai - name: GITLAB_TIMEZONE value: Beijing - name: GITLAB_SECRETS_DB_KEY_BASE value: long-and-random-alpha-numeric-string - name: GITLAB_SECRETS_SECRET_KEY_BASE value: long-and-RANDOM-ALPHA-NUMERIc-string - name: GITLAB_SECRETS_OTP_KEY_BASE value: long-and-random-alpha-numeric-string - name: GITLAB_ROOT_PASSWORD value: admin321 - name: GITLAB_ROOT_EMAIL value: 19xxxxxxxx@qq.com - name: GITLAB_HOST value: 192.168.0.6 - name: GITLAB_PORT value: “30852” - name: GITLAB_SSH_PORT value: “32353” - name: GITLAB_NOTIFY_ON_BROKEN_BUILDS value: “true” - name: GITLAB_NOTIFY_PUSHER value: “false” - name: GITLAB_BACKUP_SCHEDULE value: daily - name: GITLAB_BACKUP_TIME value: 01:00 - name: DB_TYPE value: postgres - name: DB_HOST value: postgresql - name: DB_PORT value: “5432” - name: DB_USER value: gitlab - name: DB_PASS value: passw0rd - name: DB_NAME value: gitlab_production - name: REDIS_HOST value: redis - name: REDIS_PORT value: “6379” ports: - name: http containerPort: 80 - name: ssh containerPort: 22 volumeMounts: - mountPath: /home/git/data name: data livenessProbe: httpGet: path: / port: 80 initialDelaySeconds: 180 timeoutSeconds: 5 readinessProbe: httpGet: path: / port: 80 initialDelaySeconds: 5 timeoutSeconds: 1 volumes: - name: data persistentVolumeClaim: claimName: gitlabt—-apiVersion: v1kind: Servicemetadata: name: gitlab namespace: kube-ops labels: name: gitlabspec: ports: - name: http port: 80 targetPort: http nodePort: 30852 - name: ssh port: 22 nodePort: 32353 targetPort: ssh selector: name: gitlab type: NodePort
注意：

上面文件里的GITLAB_ROOT_EMAIL应该设置成自己的邮箱地址，不要用我的，用我的你们后面注册gitlab账号会有问题
- name: GITLAB_ROOT_EMAIL value: 19xxxxxxxx@qq.com

通过kubectl apply更新yaml文件
kubectl apply -f gitlab.yaml
查看postgresql是否部署成功
kubectl get pods -n kube-ops

**访问gitlab web界面

上面部署都没问题的话，我们开始访问gitlab的web ui界面，具体步骤如下
1.查看gitlab在宿主机暴露的端口

kubectl get svc -n kube-ops
显示如下：
gitlab NodePort 10.98.248.116 80:30852/TCP,22:32353/TCP 5m25s
我们在浏览器访问k8s的master1节点的IP:30852即可访问到gitlab web界面,我访问的地址是192.168.0.6:30852，出现如下界面

第一次登陆，我们需要点击注册Registry

Full name：可以随便起名字，符合要求即可，也可和我的保持一致，如下gitlab-adminUsername：可以随便起名字，符合要求即可，也可和我的保持一致，如下gitlab-adminEmail: 这个写你们自己的邮箱，跟你们gitlab.yaml文件里的邮箱地址一致即可，我写的qq邮箱，如下198xxxxxxx@qq.comEmail confirmation: 这个就是跟上面Email对应的值保持一致即可，如下198xxxxxxx@qq.comPassword: 自己设置个密码，我设置的是admin123admin123
上面写好之后点击最下面的Registry即可完成注册并登陆

登陆之后显示如下：
