部署Gitlab
创建gitlab项目
oc new-project gitlab
创建cicd serviceaccount
$ oc create serviceaccount cicd -n gitlab
导入Gitlab模板
wget https://gitee.com/xhua/OpenshiftOneClick/raw/3.11/openshift-templates/gitlab-template.yaml oc create -f openshift-template.json -n openshift
创建持久化存储(如果没有pv的情况下)
$ cat gitlab-pv.yaml apiVersion: v1 items: - apiVersion: v1 kind: PersistentVolume metadata: creationTimestamp: null name: gitlabdata-volume spec: accessModes: - ReadWriteMany capacity: storage: 50Gi claimRef: apiVersion: v1 kind: PersistentVolumeClaim name: gitlab-data namespace: gitlab nfs: path: /mnt/gitlabdata server: 192.168.0.13 persistentVolumeReclaimPolicy: Retain status: {} - apiVersion: v1 kind: PersistentVolume metadata: creationTimestamp: null name: gitlabpostgresql-volume spec: accessModes: - ReadWriteMany capacity: storage: 10Gi claimRef: apiVersion: v1 kind: PersistentVolumeClaim name: gitlab-postgresql namespace: gitlab nfs: path: /mnt/gitlabpostgresql server: 192.168.0.13 persistentVolumeReclaimPolicy: Retain status: {} - apiVersion: v1 kind: PersistentVolume metadata: creationTimestamp: null name: gitlabredisdata-volume spec: accessModes: - ReadWriteMany capacity: storage: 50Gi claimRef: apiVersion: v1 kind: PersistentVolumeClaim name: gitlab-redis-data namespace: gitlab nfs: path: /mnt/gitlabredisdata server: 192.168.0.13 persistentVolumeReclaimPolicy: Retain status: {} - apiVersion: v1 kind: PersistentVolume metadata: creationTimestamp: null name: gitlabetc-volume spec: accessModes: - ReadWriteMany capacity: storage: 50Gi claimRef: apiVersion: v1 kind: PersistentVolumeClaim name: gitlab-etc namespace: gitlab nfs: path: /mnt/gitlabetc server: 192.168.0.13 persistentVolumeReclaimPolicy: Retain status: {} $ oc create gitlab-pv.yaml
给gitlab 容器使用root用户的权限
$ oc adm policy add-scc-to-user anyuid -z cicd -n gitlab
在Openshift上创建gitlab应用
部署应用
设置gitlab安装配置(自定义)
自定义配置1
自定义配置2
通过访问Route访问gitlab
在访问的机器上hosts文件中配置Router Host与Ip的对应
用户名(root) 密码(根据自定义配置中设定)
GitLab访问
使用Nodeport让gitlab服务支持ssh访问
Openshift上的服务最常使用的是Route来对外提供服务。但是Route只支持Http协议,而对于Gitlab通过ssh访问的方式,得通过TCP协议。所以可以使用NodePort向外提供服务。
创建NodePort (30022->gitlab 22)
$ cat gitlab-nodeport.yamlapiVersion: v1kind: Servicemetadata: name: gitlab-nodeport namespace: gitlab labels: name: gitlab-nodeportspec: type: NodePort ports: - port: 22 nodePort: 30022 name: ssh selector: app: gitlab-ce deploymentconfig: gitlab-ce $ oc create -f gitlab-nodeport.yaml
将本机的公钥拷贝到gitlab网站的ssh key管理
导入客户端的公钥
3.客户端clone代码
git clone ssh://git@gitlab.apps.it.example.com:30022/root/test.git# 或者git clone ssh://git@192.168.1.x:30022/root/test.git ##192.168.1.x为集群中任意Node的ip
注意:
因为Nodeport使用的不是ssh默认的22端口,在clone时必须在前缀使用ssh://
,同时在git服务后添加:NodePort端口号
结果展示
[root@gitlab ~]# git clone ssh://git@gitlab.apps.it.example.com:30022/root/test.gitCloning into 'test'... Warning: Permanently added '[gitlab.apps.it.example.com]:30022,[192.168.1.3]:30022' (ECDSA) to the list of known hosts. remote: Counting objects: 12, done. remote: Compressing objects: 100% (4/4), done. remote: Total 12 (delta 0), reused 0 (delta 0) Receiving objects: 100% (12/12), done.
