api-demo-com-deployment.yaml
{
"apiVersion": "apps/v1",
"kind": "Deployment",
"metadata": {
"annotations": {},
"name": "api-demo-com-deployment",
"namespace": "default"
},
"spec": {
"replicas": 1,
"revisionHistoryLimit": 2,
"selector": {
"matchLabels": {
"app": "api-demo-com"
}
},
"template": {
"metadata": {
"labels": {
"app": "api-demo-com"
}
},
"spec": {
"containers": [
{
"image": "registry.cn-hangzhou.aliyuncs.com/saas_mirroring/ali_mi_demo:v2",

}
],

],
"ip": "192.168.1.107"
}
],
"volumes": [
{
"hostPath": {
"path": "/kubernetes/wwwroot/api.demo.com"
},
"name": "data"
},
{
"hostPath": {

},

]
}
}
}
}api-demo-com-service.yaml
{
"apiVersion": "v1",

{
"port": 5000,
"protocol": "TCP",
"targetPort": 80
}
],
"selector": {
"app": "api-demo-com"
}
}
}拷贝到服务器：
执行：
sudo kubectl create -f api-demo-com-deployment.yaml
sudo kubectl create -f api-demo-com-service.yaml
三、部属nginx，Service 命名nginx 类型NodePort
nginx-deployment.yaml
{
"apiVersion": "apps/v1",
"kind": "Deployment",
"metadata": {
"annotations": {},
"labels": {
"app": "nginx"
},
"name": "nginx-deployment",
"namespace": "default"
},
"spec": {
"replicas": 1,
"revisionHistoryLimit": 2,
"selector": {
"matchLabels": {
"app": "nginx"
}
},
"template": {
"metadata": {
"labels": {
"app": "nginx"
}
},
"spec": {
"containers": [
{
"image": "docker.io/nginx:latest",
"imagePullPolicy": "IfNotPresent",
"name": "nginx",
"ports": [
{
"containerPort": 80
}
],
"resources": {
"limits": {
"cpu": "500m",
"memory": "500Mi"
},
"requests": {
"cpu": "100m",
"memory": "100Mi"
}
},
"volumeMounts": [
{
"mountPath": "/var/log/nginx",
"name": "nginx-log"
},
{
"mountPath": "/etc/nginx",
"name": "nginx-conf"
}
]
}
],
"volumes": [
{
"hostPath": {
"path": "/kubernetes/nginx/log"
},
"name": "nginx-log"
},
{
"hostPath": {
"path": "/kubernetes/nginx/conf"
},
"name": "nginx-conf"
}
]
}
}
}
}nginx-service.yaml
{
"apiVersion": "v1",
"kind": "Service",
"metadata": {
"annotations": {},
"labels": {
"app": "nginx"
},
"name": "nginx",
"namespace": "default"
},
"spec": {
"ports": [
{
"name": "http",
"nodePort": 30088,
"port": 80,
"protocol": "TCP",
"targetPort": 80
}
],
"selector": {
"app": "nginx"
},
"type": "NodePort"
}
}拷贝到服务器：
执行命令：
sudo kubectl create -f nginx-deployment.yaml
sudo kubectl create -f nginx-service.yaml 
配置nginx 及api-demo-com-site站点的反向代理，在服务器上新建目录：
/kubernetes/nginx

--nginx.conf
