实现负责消息转发、推送的网关服务
负责网络、定时、坐下、站起、重连等，支持多类游戏的无锁房间

Docker容器化

Build and Push

docker build -t panshiqu/game_server:latest -t panshiqu/game_server:1 -t panshiqu/game_server:1.0 --build-arg SERVER=game_server .
docker build -t panshiqu/gate_server:latest -t panshiqu/gate_server:1 -t panshiqu/gate_server:1.0 --build-arg SERVER=gate_server .docker push panshiqu/game_server:latest
docker push panshiqu/game_server:1
docker push panshiqu/game_server:1.0
docker push panshiqu/gate_server:latest
docker push panshiqu/gate_server:1
docker push panshiqu/gate_server:1.0# 记得调整Import，这样才能编出两个不同的版本
docker build -t panshiqu/game_server:client --target client-final .
docker build -t panshiqu/gate_server:client --target client-final .
docker push panshiqu/game_server:client
docker push panshiqu/gate_server:client

验证

# 创建网络使用别名发现服务
docker network create serverdocker run --network server --network-alias dice --name game_server -p 60001:60001 --rm panshiqu/game_server:1.0

go run main.godocker run --network server --rm -it panshiqu/game_server:client ./dice_client -ip dice

Kubernetes容器编排

部署

kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/dice.yamlkubectl create secret generic jwt --from-literal=key=ZGVmYXVsdF9rZXk=kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/gate.yamlminikube service gate --url # Mac DockerDesktop minikube print the port
cd ~/go/src/github.com/panshiqu/server/game_server/game/dice/client
go run main.go -port 60006kubectl run dice -it --rm --restart Never --image panshiqu/gate_server:client
./dice_client -ip $GATE_SERVICE_HOST

EFK (Elasticsearch + Fluentd + Kibana)

方案取自以下官方文档

日志架构
Fluentd
快速开始系列：其中Elasticsearch和Kibana

kubectl create -f https://download.elastic.co/downloads/eck/2.14.0/crds.yamlkubectl apply -f https://download.elastic.co/downloads/eck/2.14.0/operator.yamlcat <<EOF | kubectl apply -f -

更新

游戏优雅停服细节说明

请先查看资源配置中对preStop的注释
首次收到SIGTERM信号，先标记停服后等待所有房间主动解散，没有房间则无需等待
此时服务发现不再分配本服务但允许定向连接，可以进入旧房间但不允许创建新房间
可对本服所有客户端定时持续广播房间将由系统解散，请主动解散后创建新房间（待实现）
再次收到SIGTERM信号，触发解散现有房间

# 可选借助此命令将本地打包的镜像载入minikube
# minikube image load panshiqu/game_server:1.3# 可选在修改镜像前后通过调整partition来执行金丝雀发布，用以先更新并验证单个服务，值=replicas-1
# kubectl patch statefulsets dice -p '{"spec":{"updateStrategy":{"rollingUpdate":{"partition":1}}}}'kubectl set image statefulsets dice game=panshiqu/game_server:1.3kubectl rollout status statefulsets dice# 验证测试不通过可以回滚
# kubectl rollout undo statefulsets dice# kubectl patch statefulsets dice -p '{"spec":{"updateStrategy":{"rollingUpdate":{"partition":0}}}}'

网关得益于设计成重启几乎没有代价，客户端只会感到可能因为网络不好而触发了重连

kubectl set image deployments gate gate=panshiqu/gate_server:1.3

部署AB服，客户端老转新服将没有明确的时间限制

# 默认启用A服
kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/dice-ab.yamlkubectl set image statefulsets dice-b game=panshiqu/game_server:1.3# 扩容开B服
kubectl scale statefulsets dice-b --replicas=2# 启用B服
kubectl patch service dice -p '{"spec":{"selector":{"group":"b"}}}'# 缩容停A服
kubectl scale statefulsets dice-a --replicas=0
