k8s安装gitlab

这几天需要安装一个gitlab，年官方文档推荐使用helm安装，我使用helm安装好几次没有成功，还是用简单的yaml文件来安装吧。 1、安装redis，编辑gitlab-redis.yaml

[root@master gitlab]# cat gitlab-redis.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  namespace: middleware
spec:
  replicas: 1
  selector:
    matchLabels:
      name: redis
  template:
    metadata:
      name: redis
      labels:
        name: redis
    spec:
      containers:
      - name: redis
        image: sameersbn/redis:4.0.9-2
        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: middleware
  labels:
    name: redis
spec:
  ports:
    - name: redis
      port: 6379
      targetPort: redis
  selector:
    name: redis

2、编辑gitlab-postgresql.yaml配置文件

[root@master gitlab]# cat gitlab-postgresql.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgresql
  namespace: middleware
spec:
  replicas: 1
  selector:
    matchLabels:
      name: postgresql
  template:
    metadata:
      name: postgresql
      labels:
        name: postgresql
    spec:
      containers:
      - name: postgresql
        image: sameersbn/postgresql:12-20200524
        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
        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: middleware
  labels:
    name: postgresql
spec:
  ports:
    - name: postgres
      port: 5432
      targetPort: postgres
  selector:
    name: postgresql

3、编辑gitlab.yaml配置文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gitlab
  namespace: middleware
spec:
  replicas: 1
  selector:
    matchLabels:
      name: gitlab
  template:
    metadata:
      name: gitlab
      labels:
        name: gitlab
    spec:
      containers:
      - name: gitlab
        image: sameersbn/gitlab:13.8.4
        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: [e-mail]
        - name: GITLAB_HOST
          value: git.xxx.com
        - name: GITLAB_PORT
          value: "80"
        - name: GITLAB_SSH_PORT
          value: "30022"
        - 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
        emptyDir: {}

---
apiVersion: v1
kind: Service
metadata:
  name: gitlab
  namespace: middleware
  labels:
    name: gitlab
spec:
  ports:
    - name: http
      port: 80
      targetPort: http
    - name: ssh
      port: 22
      targetPort: ssh
  selector:
    name: gitlab

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: gitlab
  namespace: middleware
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
  - host: git.xxx.com
    http:
      paths:
      - backend:
          serviceName: gitlab
          servicePort: http

4、执行kubectl发布命令

[root@master gitlab]# kubectl apply -f gitlab-redis.yaml -f gitlab-postgresql.yaml -f gitlab.yaml

5、添加本地hosts文件，配置ingress

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
  name: gitlab
  namespace: middleware
spec:
  rules:
  - host: git.xxx.com
    http:
      paths:
      - backend:
          serviceName: gitlab
          servicePort: http

6、使用浏览器进行访问
