環境

centos 7.9
k8s 1.24
containerd 1.6.4

一、安裝postgresql

vim gitlab-postgresql.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gitlab-postgresql
  namespace: ops
  labels:
    name: postgresql
spec:
  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,btree_gist'
        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
        persistentVolumeClaim:
          claimName: gitlab-postgresql-pvc
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: gitlab-postgresql-pvc
  namespace: ops
spec:
  #storageClassName: "managed-nfs-storage"
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi
---
apiVersion: v1
kind: Service
metadata:
  name: postgresql
  namespace: ops
  labels:
    name: postgresql
spec:
  ports:
    - name: postgres
      port: 5432
      targetPort: postgres
  selector:
    name: postgresql
 

二、安裝redis

vim gitlab-redis.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gitlab-redis
  namespace: ops
  labels:
    name: redis
spec:
  selector:
    matchLabels:
      name: redis
  template:
    metadata:
      name: redis
      labels:
        name: redis
    spec:
      containers:
      - name: redis
        image: redis:6.2.6
        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: 30
          timeoutSeconds: 1
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: gitlab-redis-pvc
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: gitlab-redis-pvc
  namespace: ops
spec:
#  storageClassName: "managed-nfs-storage"
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi
---
apiVersion: v1
kind: Service
metadata:
  name: redis
  namespace: ops
  labels:
    name: redis
spec:
  ports:
    - name: redis
      port: 6379
      targetPort: redis
  selector:
    name: redis
 

三、安裝gitlab

vim gitlab.yaml

一定要等postgresql和redis Running之後在安裝gitlab

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gitlab
  namespace: ops
  labels:
    name: gitlab
spec:
  selector:
    matchLabels:
      name: gitlab
  template:
    metadata:
      name: gitlab
      labels:
        name: gitlab
    spec:
      initContainers:
      - name: fix-permissions
        image: busybox
        imagePullPolicy: IfNotPresent
        command: ["sh", "-c", "chown -R 1000:1000 /home/git/data"]
        securityContext:
          privileged: true
        volumeMounts:
        - name: data
          mountPath: /home/git/data
      containers:
      - name: gitlab
        image: sameersbn/gitlab:14.9.3
        imagePullPolicy: IfNotPresent
        env:

        ports:
        - name: http
          containerPort: 80
        - name: ssh
          containerPort: 22
        volumeMounts:
        - mountPath: /home/git/data
          name: data
        readinessProbe:
          httpGet:
            path: /
            port: 80
          initialDelaySeconds: 180
          timeoutSeconds: 1
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: gitlab-data-pvc
---
apiVersion: v1
