本文的部署实践过程参考了云栖文章 如何在阿里云容器服务上搭建Jenkins X并记录了更详细的过程及日志输出。
下面我们开始介绍如何在阿里云容器服务Kubernetes上快速安装部署Jenkins X。
1. 首先，需要在 阿里云容器服务控制台 创建一个Kubernetes集群，本次实践使用的环境信息如下：
master1 192.168.0.134
master2 192.168.0.135
master3 192.168.0.136
worker1 192.168.0.137
2. 登录worker1节点（也可以使用集群外的任意ecs环境）并初始化helm client
# mkdir $HOME/.kube
# scp root@192.168.0.134:/etc/kubernetes/kube.conf $HOME/.kube/config
root@192.168.0.134's password:
kube.conf 100% 5472 8.4MB/s 00:00
# scp root@192.168.0.134:/usr/local/bin/helm /usr/local/bin/helm
root@192.168.0.134's password:
helm 100% 29MB 104.0MB/s 00:00# helm init --client-only

Adding stable repo with URL: https://kubernetes-charts.storage.googleapis.com

$HELM_HOME has been configured at /root/.helm.
Not installing Tiller due to 'client-only' flag having been set
Happy Helming!3. 安装 git。
yum install git -y4. 安装jx客户端
# curl -L https://github.com/jenkins-x/jx/releases/download/v1.3.464/jx-linux-amd64.tar.gz | tar xzv
# mv jx /usr/local/bin# jx version
Using helmBinary helm with feature flag: none
NAME VERSION
jx 1.3.464
Kubernetes cluster v1.11.2
kubectl v1.11.2
helm client v2.9.1+g20adb27
helm server v2.9.1+g20adb27
git git version 1.8.3.1
A new jx version is available: 1.3.470
? Would you like to upgrade to the new jx version? No5. 下载 cloud-environments 云环境配置文件
# mkdir -p ~/.jx
# cd ~/.jx
# git clone https://github.com/haoshuwei/cloud-environments.git
正克隆到 'cloud-environments'...

# jx install --provider=kubernetes --domain aliyunk8s.com
访问日志中提示的GitHub URL 并生成API Token:
https://github.com/settings/tokens/new?scopes=repo,read:user,read:org,user:email,write:repo_hook,delete_repo
新打开一个终端窗口查看jenkins-x-platform各个组件的安装情况：
# kubectl get ing -n jx

pipelinecontroller-6b5b8d9f47-457xx 1/1 Running 0 8m发现jenkins-x-mongodb和jenkins-x-monocular-api组件启动异常，这是因为jenkins-x-monocular-api依赖jenkins-x-mongodb， 而jenkins-x-mongodb在创建pvc资源时找不到default storage class而导致的；编辑mongodb-pvc.yaml创建新pvc：
# cat mongodb-pvc.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: jenkins-x-mongodb
namespace: jx
spec:
accessModes:

docker-registry服务的访问有问题（暂时未花过多时间调试）， 但我们会在下一篇阿里云容器服务Kubernetes之Jenkins X（2）-自动化CICD实践篇中演示如何让jenkins x使用阿里云容器镜像服务来管理容器镜像；阿里云容器服务Kubernetes之Jenkins X（2）-自动化CICD实践篇 中也会使用jenkins x创建一个spring应用并演示如何使用GitOps的理念管理和发布一个云原生应用。
