3.k8s部署nacos单机版

一,编写资源清单

01-deploy-nacos.yaml

apiVersion: apps/v1        # Kubernetes API 版本（部署固定用这个）
kind: Deployment           # 资源类型：部署（管理无状态应用）
metadata:name: deploy-nacos       # Deployment 名字：deploy-nacos
spec:replicas: 1              # 副本数：只启动 1 个 Podselector:                # 标签选择器：找带有 apps=nacos 的 PodmatchLabels:apps: nacostemplate:                # Pod 模板（创建容器用的模板）metadata:labels:apps: nacos        # Pod 自带的标签，必须和上面 selector 匹配spec:containers:          # 容器列表- name: nacos        # 容器名字：nacosimage: harbor.wuflstu.com/middleware/nacos-server:v3.0.2  # 使用的镜像env:               # 环境变量（Nacos 启动必须）- name: MODEvalue: "standalone"                  # 单机模式- name: NACOS_AUTH_TOKENvalue: "MmQ4YmVkOGY3ODRlOGYxMDI0MmE5NjBkYmNhODdjZDUwY2JlYmQzY2ZhYzkzZDEzYjA3YTMzMGVmM2RiMTc3MQo="  # 安全认证 Token- name: NACOS_AUTH_IDENTITY_KEYvalue: "wufl2026"                    # 自定义认证 key- name: NACOS_AUTH_IDENTITY_VALUEvalue: "wufl"                        # 自定义认证 valueports:               # 容器暴露的端口- containerPort: 8848name: api         # 8848：Nacos 服务端口- containerPort: 8080name: web         # 8080：Nacos WebUI 端口# 存活检查：判断容器是否活着livenessProbe:exec:command: ["true"]  # 执行命令：true → 永远返回成功initialDelaySeconds: 10  # 容器启动后，等 10 秒再开始检查# 就绪检查：判断服务是否可以接收流量readinessProbe:exec:command: ["true"]  # 永远返回成功initialDelaySeconds: 10  # 启动 10 秒后直接算就绪

02-svc-nacos.yaml

apiVersion: v1
kind: Service
metadata:name: svc-nacos
spec:type: NodePortports:- port: 8080targetPort: 8080nodePort: 30080selector:apps: nacos

二,部署服务

root@master231:/opt/pods/nacos# ll
total 16
drwxr-xr-x 2 root root 4096 Apr 15 11:00 ./
drwxr-xr-x 9 root root 4096 Apr 15 09:52 ../
-rw-r--r-- 1 root root 1033 Apr 15 11:10 01-deploy-nacos.yaml
-rw-r--r-- 1 root root  173 Apr 15 09:54 02-svc-nacos.yaml服务启动
root@master231:/opt/pods/nacos# kubectl apply -f .
deployment.apps/deploy-nacos created
service/svc-nacos unchanged需要等待服务启动
