Cloudify 学习（四）：通过Cloudify的蓝图来创建第一个deployment，由k8s生成这个容器-容器编排
Cloudify4.5.0和Kubernetes1.13.0进行混合容器编排demo
- demo背景
- Local Blueprint 的编写
- 激动人心的时刻开始了，创建tomcat容器
demo背景
Cloudify4.5.0和Kubernetes1.13.0进行混合容器编排demo是基于前面两篇文章的环境而继续.
1.安装k8s1.13.0
2.安装Cloudify4.5.0
3.Cloudify对接K8s
Local Blueprint 的编写
1.点击Local Blueprint 然后点击Cloudify Composer
2.然后就是编写它，点击Source
tomcat8-5-cst.yml的内容如下：
有点需要注意：
1.这个镜像需要是配置自己的镜像仓库或者外网能拿的到的镜像：
image: ‘10.10.31.205/szy/tomcat8-5-cst:latest’
2.前面配置的K8s几个变量名，这里要引用的，注意名称要写对
eg:kubernetes_cloud_master_ip
tosca_definitions_version: cloudify_dsl_1_3
imports:
- 'http://www.getcloudify.org/spec/cloudify/4.5/types.yaml'
- 'plugin:cloudify-kubernetes-plugin'
inputs:
kubernetes_master_configuration:
default:
apiVersion: v1
kind: Config
preferences: {}
current-context: kubernetes-admin@kubernetes
clusters:
- name: kubernetes
cluster:
certificate-authority-data:
get_secret: kubernetes_cloud_certificate_authority_data
server:
concat:
- 'https://'
- get_secret: kubernetes_cloud_master_ip
- ':'
- get_secret: kubernetes_master_port
contexts:
- name: kubernetes-admin@kubernetes
context:
cluster: kubernetes
user: kubernetes-admin
users:
- name: kubernetes-admin
user:
client-certificate-data:
get_secret: kubernetes-admin_cloud_client_certificate_data
client-key-data:
get_secret: kubernetes-admin_cloud_client_key_data
node_templates:
kubernetes_master:
type: cloudify.kubernetes.nodes.Master
properties:
configuration:
file_content:
get_input: kubernetes_master_configuration
relationships: []
App_deployment:
type: cloudify.kubernetes.resources.Deployment
properties:
definition:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: container-demo
labels:
app: app-name-demo
version: v1
spec:
selector:
matchLabels:
app: app-name-demo
version: v1
replicas: 1
template:
metadata:
labels:
app: app-name-demo
version: v1
spec:
containers:
- name: container-name-demo
image: '10.10.31.205/szy/tomcat8-5-cst:latest'
ports:
- containerPort: 8080
relationships:
- type: cloudify.kubernetes.relationships.managed_by_master
target: kubernetes_master
upload后，在Local Blueprints能查看的到。
激动人心的时刻开始了，创建tomcat容器
1.Deployment -create deployments
创建时，可以选择Skip 跳过验证
部署后，可以点击Deployments的名称，进去查看日志信息
查看日志和事件信息
日志信息：

11-12-2018 22:20 mydemo4tomcat create_deployment_environment Starting 'create_deployment_environment' workflow execution
然后选择 install 安装
执行install
这样就执行OK了，状态显示已经OK，我们来k8s里来看看
k8s中已经有容器在创建了。
OK, 现在k8s的容器已经创建OK。
k8s上查看所有pods可以看的到结果。

另外：如果想在外部访问tomcat容器服务的话，需要修改下蓝图，创建service，然后通过ingress或者 外部流量访问k8s集群中service入口的一种方式（另一种方式是LoadBalancer），即nodeIP:nodePort是提供给外部流量访问k8s集群中service的入口.
下一篇文章会 ，继续更新
另外附上，Cloudify的deployments的创建日志：
