k8s部署gitlab最新版并初始化和登录

前提条件是已经部署了k8s环境，采用k8s部署gitlab作为devops的测试环境，更加简洁和方便。 1. 准备工作 1.1 创建nfs共享目录在nfs服务器创建共享目录，部署的gitlib使用共享目录来进行持久化，这样不管在哪个节点运行gitlib都没有关系。 # mkdir -p /home/k8s-nfs/gitlab/config # mkdir -p /home/k8s-nfs/gitlab/logs # mkdir -p /home/k8s-nfs/gitlab/data 1.2 添加到共享 /home/k8s-nfs/gitlab/config 192.168.17.0/8(rw,no_root_squash) /home/k8s-nfs/gitlab/logs 192.168.17.0/8(rw,no_root_squash) /home/k8s-nfs/gitlab/data 192.168.17.0/8(rw,no_root_squash) 1.3 执行更新 # service nfs restart 或者 # exportfs -r 2. 部署gitlib 2.1 准备部署文件（gitlib-deploy.yaml） apiVersion: v1 kind: Service metadata: name: gitlab spec: type: NodePort ports: # Port上的映射端口 - port: 443 targetPort: 443 name: gitlab443 - port: 80 targetPort: 80 name: gitlab80 - port: 22 targetPort: 22 name: gitlab22 selector: app: gitlab --- apiVersion: apps/v1 kind: Deployment metadata: name: gitlab spec: selector: matchLabels: app: gitlab revisionHistoryLimit: 2 template: metadata: labels: app: gitlab spec: containers: # 应用的镜像 - image: gitlab/gitlab-ce name: gitlab imagePullPolicy: IfNotPresent # 应用的内部端口 ports: - containerPort: 443 name: gitlab443 - containerPort: 80 name: gitlab80 - containerPort: 22 name: gitlab22 volumeMounts: # gitlab持久化 - name: gitlab-persistent-config mountPath: /etc/gitlab - name: gitlab-persistent-logs mountPath: /var/log/gitlab - name: gitlab-persistent-data mountPath: /var/opt/gitlab imagePullSecrets: - name: devops-repo volumes: # 使用nfs互联网存储 - name: gitlab-persistent-config nfs: server: 192.168.17.81 path: /home/k8s-nfs/gitlab/config - name: gitlab-persistent-logs nfs: server: 192.168.17.81 path: /home/k8s-nfs/gitlab/logs - name: gitlab-persistent-data nfs: server: 192.168.17.81 path: /home/k8s-nfs/gitlab/data 2.2 执行部署 # kubectl apply -f gitlib-deploy.yaml 2.3 查看部署结果 # kubectl get deploy NAME READY UP-TO-DATE AVAILABLE AGE gitlab 1/1 1 1 134m以上说明部署完成。 3. gitlib初始化 3.1 访问登录页面通过查看service映射的端口： # kubectl get svc -o wide NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTOR gitlab NodePort 10.10.129.28 443:31326/TCP,80:31320/TCP,22:31515/TCP 137m app=gitlab可以看到映射80端口的节点端口为：31320 通过制定端口访问登录页：
初始用户名为root，初始密码gitlib自动创建，在如下文件中： /etc/gitlab/initial_root_password由于是容器部署，所以，需要进入到容器中，找到对应文件，拷贝密码进行登录。文件内容类似： # WARNING: This value is valid only in the following conditions # 1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_passwo # 2. Password hasn't been changed manually, either via UI or via command line. # # If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/ Password: HCsr5VFAp28N*****************= # NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours. 3.3 登录以后的主界面
