K8s 部署 Gitlab

  • K8s 版本:1.20.6
  • 这里使用的镜像不是官方的,而是 Gitlab 容器化中使用非常多的一个第三方镜像:sameersbn/gitlab,基本上和官方保持同步更新。地址:http://www.damagehead.com/docker-gitlab/

1. Redis

apiVersion: apps/v1 kind: Deployment metadata:   name: redis   namespace: gitlab   labels:     name: redis spec:   replicas: 1   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         emptyDir: {} --- apiVersion: v1 kind: Service metadata:   name: redis   namespace: gitlab   labels:     name: redis spec:   ports:     - name: redis       port: 6379       targetPort: redis   selector:     name: redis 

2. Postgresql
