Docker容器化
Build and Push
bash
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
bash
# 创建网络使用别名发现服务
docker network create server
docker run --network server --network-alias dice --name game_server -p 60001:60001 --rm panshiqu/game_server:1.0

Kubernetes容器编排
部署

kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/dice.yaml
kubectl create secret generic jwt --from-literal=key=ZGVmYXVsdF9rZXk=
kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/gate.yaml
minikube service gate --url # Mac DockerDesktop minikube print the port
cd ~/go/src/github.com/panshiqu/server/game_server/game/dice/client

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
bash
# 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:1.3
kubectl 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
bash
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
bash
# 默认启用A服
kubectl apply -f https://raw.githubusercontent.com/panshiqu/server/main/k8s/dice-ab.yaml
kubectl 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
