在 Kubernetes 上安装 Gitlab

 

环境  k8s  1.18.3

安装

如果我们已经有可使用的 Redis 或 Postgresql 服务的话，那么直接配置在 Gitlab 环境变量中即可，如果没有的话就单独部署。

首先部署需要的 Redis 服务，对应的资源清单文件如下：(redis.yaml)  

 

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  namespace: kube-ops
  labels:
    name: redis
spec:
  selector:
    matchLabels:
      name: redis
  template:
    metadata:
      name: redis
      labels:
        name: redis
    spec:
      containers:
      - name: redis
        image: harbor.zdvictory.com/library/redis:6.0.6
        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
        emptyDir: {}

---
apiVersion: v1
kind: Service
metadata:
  name: redis
  namespace: kube-ops
  labels:
    name: redis
spec:
  ports:
    - name: redis
      port: 6379
      targetPort: redis
  selector:
    name: redis

　　

然后是数据库 Postgresql，对应的资源清单文件如下：(postgresql.yaml)

 

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgresql
  namespace: kube-ops
  labels:
    name: postgresql
spec:
  selector:
    matchLabels:
      name: postgresql
  template:
    metadata:
      name: postgresql
      labels:
        name: postgresql
    spec:
      containers:
      - name: postgresql
        image: harbor.zdvictory.com/library/postgres:12.4
        imagePullPolicy: IfNotPresent
        env:
        - name: DB_USER
          value: gitlab
        - name: DB_PASS
          value: passw0rd
        - name: DB_NAME
          value: gitlab_production
        - name: DB_EXTENSION
          value: pg_trgm
        - name: POSTGRES_PASSWORD
          value: passw0rd
        ports:
        - name: postgres
          containerPort: 5432
        volumeMounts:
        - mountPath: /var/lib/postgresql
          name: data
        livenessProbe:
          exec:
            command:
            - pg_isready
            - -h
            - localhost
            - -U
            - postgres
          initialDelaySeconds: 30
          timeoutSeconds: 5
        readinessProbe:
          exec:
            command:
            - pg_isready
            - -h
            - localhost
            - -U
            - postgres
          initialDelaySeconds: 5
          timeoutSeconds: 1
      volumes:
      - name: data
        emptyDir: {}

---
apiVersion: v1
kind: Service
metadata:
  name: postgresql
  namespace: kube-ops
  labels:
    name: postgresql
spec:
  ports:
    - name: postgres
      port: 5432
      targetPort: postgres
  selector:
    name: postgresql

　　

然后就是我们最核心的 Gitlab 的应用，对应的资源清单文件如下：(gitlab.yaml)

 

 

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gitlab
  namespace: kube-ops
  labels:

        - 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:

          initialDelaySeconds: 5
          timeoutSeconds: 1
      volumes:
