笔者已开源修改过(并附有完整 DevOps 流程)的源码:Hacker-Linner/nanoserver

熟悉 K8S 的伙伴也可以忽略此文,可以直接上手此项目的 DevOps!可以直接上手此项目的 DevOps!可以直接上手此项目的 DevOps!

相关 Dockerfile 文件准备

Dockerfile.base

准备项目在线 CI 构建基础 Image。

FROM golang:1.15-alpine

RUN go env -w GO111MODULE=on
RUN go env -w GOPROXY=https://mirrors.aliyun.com/goproxy/,direct
RUN mkdir -p /nanoserver/

WORKDIR /nanoserver
COPY go.mod go.mod
RUN go mod download

生成 Image hackerlinner/nanoserver:base

docker build -f Dockerfile.alpine.base -t hackerlinner/nanoserver:base . --no-cache

Dockerfile.alpine.base

准备项目生产基础 Image。

FROM alpine:3.12

RUN addgroup -S app \
    && adduser -S -g app app \
    && apk --no-cache add \
    ca-certificates curl netcat-openbsd

生成 Image hackerlinner/nanoserver-alpine:base

docker build -f Dockerfile.alpine.base -t hackerlinner/nanoserver-alpine:base . --no-cache

Dockerfile.prod

CI 生产构建所需的 Dockerfile

### nanoserver:base
FROM hackerlinner/nanoserver:base as builder

WORKDIR /nanoserver
COPY . .
RUN CGO_ENABLED=0 go build -a -o bin/nanoserver

### nanoserver-alpine:base
FROM hackerlinner/nanoserver-alpine:base

LABEL maintainer="为少"
WORKDIR /home/app
COPY --from=builder /nanoserver/bin/nanoserver .
COPY ./configs ./configs
RUN chown -R app:app ./
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
RUN echo 'Asia/Shanghai' >/etc/timezone
USER app
CMD ["./nanoserver"]

相关 Kubernetes 部署文件准备

Helm 3 部署 MySql

相关部署文件在:k8s/mysql

首先在你的集群中分配部署空间,这里我是 nano

kubectl create ns nano

在你的持久化服务器分配文件夹,我这里用的是 NFS

# 分配 MySql 文件夹,持久化数据 
mkdir -p /data/nfs/nano/nanoserver-mysql
chmod -R 777 /data/nfs/nano/nanoserver-mysql

创建 PV & PVC,关联到 NFS

pvc.yaml:k8s/mysql/pvc.yaml

kubectl apply -f pvc.yaml -n nano

部署:

helm install nanoserver-mysql ./mysql -f values.yaml -n nano

数据库创建:

create database

mysql -u root -phacker12345
create database scmj default character set utf8mb4 collate utf8mb4_unicode_ci;

Helm 3 部署 nanoserver

相关部署文件在:k8s/mnanoserverysql

准备 nanoserver 的 configMap,让集群统一管理 Server 配置文件。

apiVersion: v1
kind: ConfigMap
metadata:
  name: nanoserver-config
  labels:
    app: nanoserver
data:
  config.toml: |- [core] # enable debug mode debug = true heartbeat = 30 consume = "4/2,8/3,16/4" #房卡消耗, 使用逗号隔开, 局数/房卡数, 例如4局消耗1张, 8局消耗1张, 16局消耗2张, 则为: 4/1,8/1,16/2 
    #WEB服务器设置
    [webserver]
    addr = "0.0.0.0:12307"                         #监听地址
    enable_ssl = false                            #是否使用https, 如果为true, 则必须配置cert和key的路径
    static_dir = "web/static"

    #证书设置
    [webserver.certificates]
    cert = "configs/****.crt"       #证书路径
    key = "configs/****.key"        #Key路径

    [game-server]
    host = "nanoserver.your-domain.com"
    port = 30251

    # Redis server config
    [redis]
    host = "127.0.0.1"
    port = 6357

    # Mysql server config

    host = "nanoserver-mysql"
    port = 3306
    dbname = "scmj"
    password = "hacker12345"
    username = "root"
    args = "charset=utf8mb4"
    buf_size = 10
    max_idle_conns = 20
    max_open_conns = 15
    show_sql = true

    # 微信
    [wechat]
    appid = "YOUR_WX_APPID"
    appsecret = "YOUR_APP_SECRET"
    callback_url = "YOUR_CALLBACK"
    mer_id = "YOUR_MER_ID"
    unify_order_url = "https://api.mch.weixin.qq.com/pay/unifiedorder"

    #Token设置
    [token]
    expires = 21600                        #token过期时间

    #白名单设置
    [whitelist]
    ip = ["10.10.*", "127.0.0.1", ".*"]                 #白名单地址, 支持golang正则表达式语法

    #分享信息
    [share]
    title = "血战到底"
    desc = "纯正四川玩法,快捷便利的掌上血战,轻松组局,随时随地尽情游戏"

    #更新设置
    [update]
    force = true #是否强制更新
    version = "1.9.3"
    android = "https://fir.im/tand"
    ios = "https://fir.im/tios"

    #联系设置
    [contact]
    daili1 = "kefuweixin01"
    daili2 = "kefuweixin01"
    kefu1 = "kefuweixin01"

    appkey = "xxx"

    #广播消息
    [broadcast]
    message = ["系统消息:健康游戏,禁止赌博", "欢迎进入游戏"]

    #登陆相关
    [login]
    guest = true
    lists = ["test", "konglai"]

关于 ingressroute-tcp.yaml,因为 nanoserver 本身会启动两个服务器 webgame

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteTCP
metadata:
  name: nanoserver-game-route
spec:
  entryPoints:
    - nanoserver-gm # 需要在 traefik 的部署配置中设置
  routes:
    - match: HostSNI(`*`)
      kind: Rule
      services:
        - name: nanoserver
          port: 30251

ingressroute-tcp.yamlgame 对外的入口,因为我用的是 traefik,所以需要它。

Drone CI/CD 配置

.drone.yml

kind: pipeline
type: kubernetes
name: NanoServer

steps:

  - name: 更新 Chart.yaml appVersion
    image: busybox
    commands:
      - echo $DRONE_COMMIT
      - '[ -n "$DRONE_COMMIT" ] && ( sed -i "s/APP_VERSION/${DRONE_COMMIT}/g" k8s/nanoserver/nanoserver/Chart.yaml; )'
      - cat k8s/nanoserver/nanoserver/Chart.yaml

  - name: 构建 Docker Image
    image: plugins/docker
    settings:
      debug: true
      dockerfile: Dockerfile.prod
      repo: hub.your-domain.com/library/nanoserver
      tags: ${DRONE_COMMIT}
      registry: hub.your-domain.com
      username:
        from_secret: docker_user
      password:
        from_secret: docker_pass

  - name: 上云(HelmV3) -> K8S Cluster
    image: pelotech/drone-helm3
    settings:
      helm_command: upgrade
      chart: ./k8s/nanoserver/nanoserver
      release: nanoserver
      vaules_yaml: ./k8s/nanoserver/values.yaml
      namespace: nano
      api_server:
        from_secret: api_server
      kubernetes_token:
        from_secret: k8s_token
      skip_tls_verify: true

trigger:
  branch:
    - master

关于 api_serverk8s_token,玩过 kubernetes 的童鞋应该都知道,我就不赘述了。
